Anemia
Which statement by the client is indicative of their condition?
Explanation
Choice A rationale:
The client's statement, "I've been experiencing frequent nosebleeds lately," is indicative of iron-deficiency anemia.
Iron is essential for the formation of hemoglobin, which carries oxygen in red blood cells.
When there is a deficiency of iron, the blood vessels in the nose can become fragile, leading to frequent nosebleeds.
This is a common symptom of iron-deficiency anemia.
Choice B rationale:
The client's statement, "I've been eating a lot of leafy greens in my diet," is not indicative of iron-deficiency anemia.
In fact, consuming leafy greens is a good dietary source of iron, which can help prevent iron deficiency.
Choice C rationale:
The client's statement, "I've had a fever for the past week," is not indicative of iron-deficiency anemia.
Fever is typically associated with infections or inflammatory conditions, not anemia.
Choice D rationale:
The client's statement, "I've been feeling more energetic than usual," is not indicative of iron-deficiency anemia.
In fact, one of the hallmark symptoms of iron-deficiency anemia is fatigue and a lack of energy due to reduced oxygen-carrying capacity in the blood.
Which statement by the nurse is accurate regarding iron absorption?
Explanation
Choice A rationale:
The nurse's statement, "Iron absorption can be impaired by consuming green leafy vegetables," is not accurate.
Green leafy vegetables contain non-heme iron, which is less readily absorbed than heme iron found in animal products.
However, they do not impair iron absorption.
Choice B rationale:
The nurse's statement, "Inadequate iron intake is usually caused by chronic diseases," is not accurate.
Inadequate iron intake is typically caused by dietary factors, such as a lack of iron-rich foods in the diet.
Chronic diseases can lead to anemia, but they do so by affecting the body's utilization of iron, not by causing inadequate intake.
Choice D rationale:
The nurse's statement, "Excessive iron loss can occur due to pregnancy and lactation," is partially accurate.
Pregnancy and lactation can lead to increased iron requirements, but they do not directly cause excessive iron loss.
Iron loss through menstruation is a more common cause of iron deficiency in women.
Select all the types of anemia that are characterized by RBCs that are smaller than normal.
Explanation
Choice A rationale:
Microcytic anemia is characterized by red blood cells (RBCs) that are smaller than normal.
This can occur in conditions like iron-deficiency anemia and thalassemia, where there is impaired hemoglobin production or insufficient iron for RBC formation.
Choice B rationale:
Normocytic anemia is characterized by RBCs that are of normal size.
This can occur in various conditions, including chronic diseases like chronic kidney disease and some types of anemia of chronic inflammation.
Choice C rationale:
Macrocytic anemia is characterized by RBCs that are larger than normal.
This can be seen in conditions like megaloblastic anemia, which is often caused by vitamin B12 or folate deficiency.
Choice D rationale:
Anisocytosis refers to a condition where RBCs are of unequal sizes.
While it is not a specific type of anemia, anisocytosis can be seen in various types of anemia, including iron-deficiency anemia, as RBCs may vary in size due to different stages of development.
Choice E rationale:
Poikilocytosis refers to a condition where RBCs have abnormal shapes.
Like anisocytosis, poikilocytosis is not a specific type of anemia but can be observed in various anemias, including sickle cell anemia, where RBCs take on a characteristic crescent shape.
What condition might have caused this type of anemia in the client?
Explanation
Choice A rationale:
Iron deficiency Iron deficiency anemia is characterized by a decrease in the body's iron stores, which results in reduced hemoglobin synthesis and decreased oxygen-carrying capacity of red blood cells (RBCs)
This condition is typically caused by insufficient dietary iron intake, malabsorption of iron, or blood loss, but it does not involve increased RBC destruction.
Therefore, iron deficiency is not the correct choice for the cause of anemia in this client.
Choice B rationale:
Vitamin B12 deficiency Vitamin B12 deficiency can lead to a type of anemia known as megaloblastic anemia, which is characterized by larger-than-normal RBCs and inadequate hemoglobin production.
However, this condition is not typically associated with increased RBC destruction.
Vitamin B12 deficiency anemia is usually caused by inadequate dietary intake, malabsorption, or certain medical conditions affecting vitamin B12 absorption, but it does not fit the scenario described in the question.
Therefore, vitamin B12 deficiency is not the correct choice for the cause of anemia in this client.
Choice C rationale:
Autoimmune disease (Correct Choice) Autoimmune diseases can lead to hemolytic anemias, a group of disorders characterized by the premature destruction of RBCs by the immune system.
In these conditions, the immune system mistakenly recognizes RBCs as foreign invaders and targets them for destruction.
This process results in anemia due to increased RBC destruction.
Conditions such as autoimmune hemolytic anemia (AIHA) and autoimmune thrombocytopenic purpura (ITP) are examples of autoimmune diseases that can cause hemolytic anemia.
Therefore, autoimmune disease is the correct choice for the cause of anemia in this client.
Choice D rationale:
Bone marrow disorder Bone marrow disorders, such as aplastic anemia or myelodysplastic syndrome, can lead to anemia by affecting the production of RBCs in the bone marrow.
However, these disorders do not typically involve increased RBC destruction.
Instead, they result in a decreased production of RBCs, leading to anemia.
Therefore, a bone marrow disorder is not the correct choice for the cause of anemia in this client.
What is the most likely reason for these symptoms in the client?
Explanation
Choice A rationale:
Increased oxygen-carrying capacity of the blood Increased oxygen-carrying capacity of the blood would not result in symptoms of fatigue, shortness of breath, and headache.
In fact, having more oxygen-carrying capacity would be expected to improve oxygen delivery to tissues, which would not cause these symptoms.
Therefore, this choice is not the correct reason for the client's symptoms.
Choice B rationale:
Tissue hypoxia (Correct Choice) Anemia is characterized by a decreased concentration of hemoglobin in the blood, which leads to reduced oxygen-carrying capacity.
As a result, tissues and organs may not receive an adequate supply of oxygen, leading to symptoms such as fatigue, shortness of breath, and headache.
Tissue hypoxia is the most likely reason for these symptoms in a client with anemia, as the body struggles to meet its oxygen demands due to the decreased hemoglobin levels.
Choice C rationale:
Excessive iron intake Excessive iron intake would not typically cause the symptoms of fatigue, shortness of breath, and headache.
Instead, excessive iron intake can lead to iron overload, which may result in gastrointestinal symptoms, liver damage, and other complications.
It is not a likely cause of anemia-related symptoms in this context.
Choice D rationale:
Enhanced immune function Enhanced immune function would not be a direct cause of symptoms like fatigue, shortness of breath, and headache in a client with anemia.
While anemia can weaken the immune system to some extent, it does not lead to enhanced immune function that would result in these particular symptoms.
Therefore, this choice is not the correct reason for the client's symptoms.
The client reports feeling fatigued and weak.
Which of the following clinical manifestations are consistent with iron-deficiency anemia in this client?
Explanation
Choice A rationale:
"My tongue has been inflamed lately." Inflammation of the tongue, a condition known as glossitis, can be a clinical manifestation of iron-deficiency anemia.
When the body lacks sufficient iron, it may not produce enough hemoglobin, which can lead to changes in the appearance and texture of the tongue.
Glossitis can cause the tongue to become red, swollen, and sore.
This symptom is consistent with iron-deficiency anemia.
Choice B rationale:
"I have a craving for ice all the time." Pica, which involves cravings for non-nutritive substances like ice, is a classic symptom of iron-deficiency anemia.
While the exact cause of pica in iron deficiency is not fully understood, it is considered a manifestation of the body's attempt to obtain more iron.
This unusual craving for ice or other non-food items is a significant indicator of iron-deficiency anemia.
Choice C rationale:
"I've been experiencing chest pain." Chest pain is not a typical manifestation of iron-deficiency anemia.
Instead, it may be associated with other cardiovascular or respiratory conditions.
Iron-deficiency anemia primarily affects the blood's oxygen-carrying capacity and may lead to symptoms such as fatigue, pallor, weakness, and shortness of breath, but chest pain is not a direct consequence of this type of anemia.
Choice D rationale:
"I often faint when I stand up." Fainting upon standing up may be indicative of orthostatic hypotension, which can occur in various medical conditions but is not a specific symptom of iron-deficiency anemia.
Iron-deficiency anemia can lead to weakness and dizziness, but fainting when changing positions may suggest other factors, such as blood pressure regulation issues.
The client's laboratory results show a low hemoglobin level and microcytic, hypochromic red blood cells on the peripheral blood smear.
What other laboratory findings are consistent with iron-deficiency anemia in this client?
Explanation
Choice A rationale:
Elevated serum iron levels are not consistent with iron-deficiency anemia.
Iron-deficiency anemia is characterized by low serum iron levels, as the body lacks sufficient iron to produce hemoglobin.
In this case, the client mentions that their serum iron levels are within the normal range, which does not align with the typical findings of iron-deficiency anemia.
Choice B rationale:
Transferrin saturation measures the amount of iron bound to transferrin in the blood.
In iron-deficiency anemia, transferrin saturation is typically below 20% because there is insufficient iron available for binding to transferrin.
Therefore, the statement that "My transferrin saturation is above 20%" is inconsistent with the diagnosis of iron-deficiency anemia.
Choice C rationale:
Serum ferritin is a key indicator of iron stores in the body.
In iron-deficiency anemia, serum ferritin levels are significantly decreased because the body has depleted its iron stores to maintain essential functions like hemoglobin synthesis.
Therefore, the statement "My serum ferritin is significantly elevated" contradicts the typical laboratory findings of iron-deficiency anemia.
Choice D rationale:
The mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) are both red blood cell indices.
In iron-deficiency anemia, these indices are often decreased, resulting in microcytic (small) and hypochromic (pale) red blood cells.
Therefore, the statement "My MCV and MCHC are both within the normal range" does not align with the characteristic findings of iron-deficiency anemia.
Which of the following factors should the nurse include as potential causes of iron-deficiency anemia? (Select all that apply.)
Explanation
Choice A rationale:
Chronic gastrointestinal bleeding is a common cause of iron-deficiency anemia.
Blood loss from the gastrointestinal tract leads to the loss of iron, ultimately depleting iron stores in the body and impairing hemoglobin synthesis.
Choice B rationale:
High serum iron levels are not a potential cause of iron-deficiency anemia.
Iron-deficiency anemia is characterized by low serum iron levels, as the body lacks sufficient iron to produce hemoglobin.
Choice C rationale:
Inadequate dietary intake of iron can lead to iron-deficiency anemia, especially in individuals who do not consume enough iron-rich foods.
A lack of dietary iron can result in reduced iron absorption and insufficient iron stores in the body.
Choice D rationale:
Elevated serum ferritin levels are not a potential cause of iron-deficiency anemia.
In fact, elevated serum ferritin levels are more indicative of iron overload conditions rather than iron deficiency.
Choice E rationale:
Increased erythropoietic activity can be a compensatory response to iron-deficiency anemia.
When the body senses low oxygen-carrying capacity due to reduced hemoglobin levels, it may increase erythropoietin production, leading to the production of more red blood cells (erythropoiesis) in an attempt to improve oxygen delivery to tissues.
Which of the following findings would confirm the diagnosis of iron-deficiency anemia?
Explanation
Choice A rationale:
High serum iron levels and low total iron-binding capacity (TIBC) are not indicative of iron-deficiency anemia.
In this scenario, elevated serum iron levels contradict the typical finding of low serum iron levels in iron-deficiency anemia.
Choice B rationale:
High mean corpuscular volume (MCV) and high mean corpuscular hemoglobin (MCH) are not consistent with the characteristic findings of iron-deficiency anemia.
Iron-deficiency anemia typically results in microcytic (small) and hypochromic (pale) red blood cells, leading to low MCV and low MCH.
Choice C rationale:
Low hemoglobin and low hematocrit are consistent with the diagnosis of iron-deficiency anemia.
In this condition, there is insufficient iron available to produce hemoglobin, leading to decreased hemoglobin levels and reduced hematocrit.
Choice D rationale:
Elevated mean corpuscular hemoglobin concentration (MCHC) and low red cell distribution width (RDW) are not typical findings of iron-deficiency anemia.
Iron-deficiency anemia is characterized by hypochromic (pale) red blood cells and often results in increased RDW due to variability in red cell size (anisocytosis)
Elevated MCHC is not expected in iron-deficiency anemia.
The nurse observes that the client has pallor and spoon-shaped nails.
Which additional clinical manifestation should the nurse expect to assess in this client?
Explanation
Choice A rationale:
Restless legs syndrome is not typically associated with iron-deficiency anemia.
The hallmark clinical manifestations of iron-deficiency anemia include pallor, spoon-shaped nails (koilonychia), fatigue, weakness, and cold intolerance.
Restless legs syndrome is characterized by uncomfortable sensations in the legs and an irresistible urge to move them, which is unrelated to iron-deficiency anemia.
Choice B rationale:
High transferrin saturation is not an expected clinical manifestation of iron-deficiency anemia.
In fact, iron-deficiency anemia is characterized by a decrease in transferrin saturation.
Transferrin saturation is a measure of the iron-carrying capacity of transferrin in the blood.
In iron-deficiency anemia, the body struggles to adequately transport iron, leading to low transferrin saturation.
Choice C rationale:
Normal white blood cell count is not a typical clinical manifestation of iron-deficiency anemia.
Iron-deficiency anemia primarily affects red blood cells and their ability to carry oxygen.
While anemia may lead to fatigue and weakness, it does not directly impact white blood cell counts.
Choice D rationale:
Elevated serum iron levels are not expected in iron-deficiency anemia.
In fact, iron-deficiency anemia is characterized by low serum iron levels due to insufficient iron stores in the body.
Elevated serum iron levels may be seen in other types of anemia or conditions, but they are not a hallmark of iron-deficiency anemia.
Which components should be included in the nursing assessment for this patient?
Explanation
Choice A rationale:
Review of the results of the CBC (Complete Blood Count) with differential and peripheral blood smear is essential in assessing a patient with iron-deficiency anemia.
The CBC provides information about hemoglobin levels, hematocrit, mean corpuscular volume (MCV), and red blood cell indices, which are crucial in diagnosing and monitoring anemia.
A peripheral blood smear can help identify the characteristic microcytic and hypochromic red blood cells seen in iron-deficiency anemia.
Choice B rationale:
Monitoring the patient's vital signs and oxygen saturation is essential in the assessment of a patient with iron-deficiency anemia.
Anemia can lead to reduced oxygen-carrying capacity in the blood, potentially causing symptoms such as shortness of breath and tachycardia.
Monitoring vital signs and oxygen saturation helps assess the patient's response to anemia and the need for oxygen supplementation.
Choice C rationale:
Administering iron supplements as prescribed is a nursing intervention rather than a component of the nursing assessment.
While it is important for the management of iron-deficiency anemia, the assessment phase involves gathering data about the patient's condition, not implementing interventions.
Choice D rationale:
Providing emotional support and counseling to the patient and family members is a crucial component of nursing care for patients with iron-deficiency anemia.
Anemia can have a significant impact on a patient's quality of life, causing fatigue, weakness, and emotional distress.
Offering emotional support and education to the patient and family members helps them cope with the condition and its management.
What should the nurse teach the client about taking iron supplements correctly?
Explanation
Choice A rationale:
Taking iron supplements with dairy products is not recommended for optimal iron absorption.
Calcium, present in dairy products, can inhibit the absorption of iron.
Therefore, it is best to take iron supplements separately from dairy products.
Choice B rationale:
Taking iron supplements on an empty stomach is the correct recommendation.
Iron absorption is enhanced when the supplements are taken on an empty stomach.
However, some individuals may experience gastrointestinal discomfort when taking iron on an empty stomach.
In such cases, it can be taken with a small amount of food that does not contain dairy products or high in calcium.
Choice C rationale:
Taking iron supplements with antacids is not recommended to reduce gastrointestinal side effects.
Antacids containing calcium can interfere with iron absorption, potentially worsening the anemia.
Therefore, it is best to avoid taking iron supplements with antacids.
Choice D rationale:
Taking iron supplements with a large meal is not the most effective way to improve their effectiveness.
In fact, taking iron supplements with a large meal can decrease iron absorption due to competition with other nutrients.
It is generally recommended to take iron supplements on an empty stomach or with a small, iron-friendly snack if gastrointestinal discomfort occurs.
A nurse is caring for a patient with iron-deficiency anemia.
Which nursing interventions are appropriate for this patient? Select all that apply.
Explanation
Choice A rationale:
Administering blood transfusions as prescribed.
Administering blood transfusions is not typically the first-line treatment for iron-deficiency anemia.
Blood transfusions are usually reserved for severe cases of anemia or when other treatments have failed.
Iron replacement therapy is the primary treatment for iron-deficiency anemia.
Choice B rationale:
Monitoring the patient's response to erythropoiesis-stimulating agents (ESAs)
Monitoring the patient's response to ESAs is appropriate because ESAs stimulate the production of red blood cells and can be used in the treatment of anemia, especially in chronic kidney disease patients.
However, ESAs are not the primary treatment for iron-deficiency anemia, so this choice is not the only appropriate intervention.
Choice C rationale:
Educating the patient about the causes, symptoms, and complications of sickle cell anemia.
Educating the patient about sickle cell anemia is not relevant to the care of a patient with iron-deficiency anemia.
Iron-deficiency anemia and sickle cell anemia are two distinct conditions with different causes, symptoms, and treatments.
Choice D rationale:
Encouraging the patient to eat a balanced diet rich in iron.
Encouraging the patient to eat a balanced diet rich in iron is an appropriate nursing intervention for a patient with iron-deficiency anemia.
Iron-rich foods can help replenish the body's iron stores and support the treatment of anemia.
Choice E rationale:
Providing emotional support and counseling to the patient and family members.
Providing emotional support and counseling is an important aspect of nursing care for any patient, including those with iron-deficiency anemia.
Dealing with a chronic condition can be emotionally challenging for patients and their families.
Emotional support can help improve the patient's overall well-being and compliance with treatment.
Which treatment option is typically reserved for cases of severe or symptomatic anemia that does not respond to iron supplements?
Explanation
Choice A rationale:
Administering iron supplements as prescribed.
Administering iron supplements is the primary treatment for iron-deficiency anemia.
However, in severe cases of anemia where the patient is symptomatic or unresponsive to iron supplements, blood transfusions may be necessary.
Choice B rationale:
Administering erythropoiesis-stimulating agents (ESAs)
ESAs can be used in the treatment of anemia, especially in chronic kidney disease patients, but they are not typically the first-line treatment for iron-deficiency anemia.
Iron replacement therapy is the primary approach to managing this condition.
Choice C rationale:
Administering blood transfusions as prescribed.
Administering blood transfusions is the correct choice for severe cases of iron-deficiency anemia that do not respond to iron supplements.
Blood transfusions can quickly increase the patient's red blood cell count and alleviate symptoms.
Choice D rationale:
Encouraging the patient to eat a balanced diet rich in iron.
Encouraging a balanced diet is important for preventing and managing iron-deficiency anemia, but it is not typically reserved for severe or symptomatic cases that do not respond to iron supplements.
In such cases, more immediate interventions like blood transfusions may be necessary.
What is the primary goal of treatment and management for this client?
Explanation
Choice A rationale:
To correct the underlying cause of iron deficiency.
The primary goal of treatment and management for a client with iron-deficiency anemia is to correct the underlying cause of iron deficiency.
This may involve addressing dietary deficiencies, identifying and treating gastrointestinal bleeding, or managing chronic conditions that contribute to iron loss.
Correcting the underlying cause is essential for long-term management.
Choice B rationale:
To restore normal hemoglobin and iron levels.
Restoring normal hemoglobin and iron levels is certainly a goal of treatment for iron-deficiency anemia, but it is not the primary goal.
Normalizing hemoglobin and iron levels is a means to an end, with the ultimate goal being to correct the underlying cause of the deficiency.
Choice C rationale:
To prevent or treat complications of anemia.
Preventing or treating complications of anemia is an important aspect of management, but it is not the primary goal.
Complications such as fatigue, weakness, and impaired oxygen delivery are addressed through the correction of the underlying iron deficiency.
Choice D rationale:
To provide immediate relief of anemia symptoms.
Providing immediate relief of anemia symptoms is a short-term goal of treatment, but it is not the primary goal.
The primary focus should be on addressing the root cause of iron deficiency to achieve long-term improvement in the patient's overall health and well-being.
Vitamin B12 deficiency anemia
Which statement by the patient indicates a possible cause of their condition?
Explanation
Choice A rationale:
Following a strict vegan diet can lead to vitamin B12 deficiency as it is primarily found in animal products.
However, the patient's recent gastrectomy is a more likely cause of their condition.
Choice B rationale:
This is the correct answer.
A gastrectomy can interfere with the absorption of vitamin B12 in the stomach, leading to a deficiency.
Choice C rationale:
Regular use of acid-suppressing drugs may affect the absorption of some nutrients, including vitamin B12, but it is not as direct a cause as a gastrectomy.
Choice D rationale:
Family history of pernicious anemia indicates a genetic predisposition, but it may not be the direct cause in this case.
The gastrectomy is a more likely cause.
Which statement made by the client reflects a potential effect of this condition on their health?
Explanation
Choice A rationale:
Pale skin (pallor) is a common symptom of anemia, but it is not specific to vitamin B12 deficiency anemia.
Many types of anemia can lead to paler skin.
Choice B rationale:
Joint pain and stiffness are not typically associated with vitamin B12 deficiency anemia.
This symptom is more characteristic of other conditions, such as arthritis.
Choice C rationale:
This is the correct answer.
Feeling lightheaded and dizzy when standing up quickly is a common symptom of anemia, including vitamin B12 deficiency anemia.
Anemia can lead to decreased oxygen delivery to the brain, resulting in dizziness upon sudden position changes.
Choice D rationale:
Higher energy levels are not a typical symptom of vitamin B12 deficiency anemia.
Fatigue and weakness are more common symptoms of this condition.
A nurse is assessing a patient with suspected vitamin B12 deficiency anemia.
Which clinical manifestations should the nurse be alert to? (Select three.)
Explanation
Choice A rationale:
Jaundice is not a typical manifestation of vitamin B12 deficiency anemia.
It is more commonly associated with liver dysfunction or hemolytic anemias.
Choice B rationale:
This is a correct answer.
Glossitis, which is inflammation of the tongue, can be a clinical manifestation of vitamin B12 deficiency anemia.
The tongue may appear red and swollen.
Choice C rationale:
This is a correct answer.
Peripheral neuropathy, characterized by tingling, numbness, and weakness in the extremities, can result from long-term vitamin B12 deficiency.
Choice D rationale:
Increased platelet count (thrombocytosis) is not a typical manifestation of vitamin B12 deficiency anemia.
It may occur in other conditions, such as inflammation or reactive thrombocytosis.
Choice E rationale:
This is a correct answer.
Oval-shaped red blood cells (macro-ovalocytes) can be observed in the blood smear of individuals with vitamin B12 deficiency anemia.
These abnormally shaped red blood cells are a characteristic finding.
What is the primary reason for administering vitamin B12 via injections rather than oral supplements?
Explanation
Choice A rationale:
Oral supplements are less effective in raising vitamin B12 levels.
Rationale: Vitamin B12 deficiency anemia often results from malabsorption issues in the gastrointestinal tract, where the body cannot adequately absorb vitamin B12 from the digestive system.
In such cases, oral supplements may not be effective because they rely on the digestive system for absorption.
In contrast, vitamin B12 injections bypass the gastrointestinal tract, delivering the vitamin directly into the bloodstream, ensuring absorption, and increasing the effectiveness of treatment.
Choice B rationale:
Injections are less painful for the client.
Rationale: While the pain associated with injections can vary from person to person, it is not the primary reason for choosing injections over oral supplements in the treatment of vitamin B12 deficiency anemia.
The primary consideration is the effectiveness of absorption, as discussed in Choice A's rationale.
Choice C rationale:
Injections have fewer side effects.
Rationale: Both oral supplements and vitamin B12 injections have their own set of potential side effects, but the choice between the two primarily depends on the underlying cause of the deficiency and the ability to absorb vitamin B12.
Therefore, the assertion that injections have fewer side effects is not the primary reason for choosing them.
Choice D rationale:
Oral supplements may cause gastrointestinal distress.
Rationale: This is the correct answer.
Oral supplements of vitamin B12 may cause gastrointestinal distress, particularly in individuals with gastrointestinal issues.
These supplements can be hard for some individuals to tolerate, leading to discomfort, gas, or other gastrointestinal symptoms.
This is a significant consideration when choosing the route of administration for vitamin B12 treatment.
What information should the nurse include in the teaching plan regarding dietary sources of vitamin B12?
Explanation
Choice A rationale:
"Include more leafy green vegetables in your diet." Rationale: This statement is incorrect because leafy green vegetables are not a significant source of vitamin B12.
Vitamin B12 is primarily found in animal products such as meat, poultry, fish, and dairy.
Leafy green vegetables are sources of other essential nutrients like folate, but they do not contain vitamin B12.
Choice B rationale:
"Increase your consumption of red meat and poultry." Rationale: This is the correct answer.
Red meat and poultry are excellent dietary sources of vitamin B12.
Consuming these foods can help individuals increase their vitamin B12 intake, which is crucial for addressing vitamin B12 deficiency anemia.
Choice C rationale:
"Avoid dairy products to prevent exacerbating the deficiency." Rationale: This statement is incorrect.
Dairy products are a good source of vitamin B12, and avoiding them may worsen a vitamin B12 deficiency.
It is important to include dairy products in the diet, especially for individuals with vitamin B12 deficiency anemia.
Choice D rationale:
"Consume more citrus fruits for their vitamin B12 content." Rationale: This statement is incorrect.
Citrus fruits are not a source of vitamin B12.
They are known for their vitamin C content, but vitamin B12 is primarily found in animal-based foods.
The patient complains of soreness, redness, and smoothness of the tongue.
What distinctive feature of vitamin B12 deficiency anemia does this symptom indicate?
Explanation
Choice A rationale:
Dyspnea.
Rationale: Dyspnea refers to difficulty breathing and is not a characteristic symptom of vitamin B12 deficiency anemia.
Symptoms of vitamin B12 deficiency anemia are primarily related to the blood and nervous system.
Choice B rationale:
Numbness and tingling of extremities.
Rationale: Numbness and tingling of extremities (peripheral neuropathy) can be a symptom of vitamin B12 deficiency anemia, but it is not related to the specific complaint of soreness, redness, and smoothness of the tongue mentioned in the question.
Choice C rationale:
Glossitis.
Rationale: This is the correct answer.
Glossitis refers to inflammation of the tongue, which can result in soreness, redness, and a smooth appearance of the tongue.
It is a distinctive feature of vitamin B12 deficiency anemia, as vitamin B12 plays a role in maintaining the health of the oral mucosa and nerves.
Choice D rationale:
Memory loss.
Rationale: Memory loss is not a typical symptom of vitamin B12 deficiency anemia.
Symptoms related to the nervous system, such as numbness and tingling, are more common neurological manifestations of the condition.
The nurse observes these neuropsychiatric symptoms during the assessment.
Which of the following statements best describes the significance of these symptoms in relation to vitamin B12 deficiency anemia?
Explanation
They are neuropsychiatric symptoms associated with vitamin B12 deficiency anemia.
Choice A rationale:
These neuropsychiatric symptoms are actually related to vitamin B12 deficiency anemia.
Vitamin B12 deficiency can lead to neurological symptoms, including confusion, irritability, and depression.
It is not unrelated to the condition.
Choice B rationale:
Gastrointestinal symptoms are not the primary manifestation of vitamin B12 deficiency anemia.
Choice C rationale:
Glossitis is a common sign of vitamin B12 deficiency anemia, but it primarily involves inflammation and changes in the tongue.
While glossitis is associated with vitamin B12 deficiency, it does not fully explain the neuropsychiatric symptoms mentioned in the question.
Choice D rationale:
The correct answer is choice D.
Neuropsychiatric symptoms such as confusion, irritability, and depression are indeed associated with vitamin B12 deficiency anemia.
Which laboratory test measures the absorption of radioactive vitamin B12 in the urine and helps differentiate between pernicious anemia and other causes of malabsorption?
Explanation
Schilling test.
Choice A rationale:
A complete blood count (CBC) is a common blood test that provides information about the number and types of blood cells but does not directly measure the absorption of vitamin B12 in the urine.
It is not the test used to differentiate between pernicious anemia and other causes of malabsorption.
Choice B rationale:
Serum vitamin B12 level measures the amount of vitamin B12 in the blood but does not directly assess its absorption in the urine.
While it is a valuable test for diagnosing vitamin B12 deficiency, it does not differentiate between pernicious anemia and other causes of malabsorption.
Choice C rationale:
Serum folate level measures the amount of folate (a different B vitamin) in the blood and is not specific to vitamin B12 deficiency or malabsorption of vitamin B12.
It does not help differentiate between pernicious anemia and other causes of malabsorption.
Choice D rationale:
Serum homocysteine level can be elevated in cases of vitamin B12 deficiency, but it is not a direct test of vitamin B12 absorption in the urine.
It also does not differentiate between pernicious anemia and other causes of malabsorption.
Choice E rationale:
The correct answer is choice E.
The Schilling test measures the absorption of radioactive vitamin B12 in the urine and is specifically designed to differentiate between pernicious anemia (a type of B12 deficiency caused by impaired absorption) and other causes of malabsorption.
This test helps identify the underlying cause of vitamin B12 deficiency.
The mean corpuscular volume (MCV) is above 100 fL.
Which of the following laboratory tests would further confirm the diagnosis of vitamin B12 deficiency anemia?
Explanation
Serum vitamin B12 level.
Choice A rationale:
Serum folate level does not confirm vitamin B12 deficiency anemia.
While both vitamin B12 and folate deficiencies can lead to similar types of anemia (macrocytic and hypochromic), measuring serum folate levels alone will not confirm the diagnosis of vitamin B12 deficiency anemia.
Choice B rationale:
The correct answer is choice B.
A serum vitamin B12 level test is a crucial diagnostic tool for confirming vitamin B12 deficiency anemia.
In this case, where the client presents with macrocytic (large) and hypochromic (pale) RBCs with low hemoglobin (Hgb) and hematocrit (Hct) levels and an elevated mean corpuscular volume (MCV) above 100 fL, a low serum vitamin B12 level would confirm the diagnosis.
Choice C rationale:
Serum homocysteine level can be elevated in cases of vitamin B12 deficiency, but it is not a specific test for confirming the diagnosis of vitamin B12 deficiency anemia.
It may be used as an additional marker, but it should not be the primary test for confirmation.
Choice D rationale:
Reticulocyte count measures the percentage of young, immature red blood cells in the blood and is not a specific test for confirming vitamin B12 deficiency anemia.
While anemia is present in this case, it does not provide direct information about the underlying cause, which is best confirmed by measuring serum vitamin B12 levels.
A nurse is performing a physical examination on a patient with suspected vitamin B12 deficiency anemia.
What aspect of the examination is crucial to assess in order to identify signs of pallor or jaundice?
Explanation
Choice A rationale:
Assessing vital signs is important for overall patient assessment, but it is not the most crucial aspect when identifying signs of pallor or jaundice.
Vital signs help in evaluating the patient's general condition and stability.
Choice B rationale:
Heart sounds are important for assessing cardiac function and may provide information on the patient's cardiovascular status, but they are not the most crucial aspect when identifying signs of pallor or jaundice.
Choice C rationale:
Lung sounds are essential for evaluating the respiratory status of the patient, but they do not directly help in identifying signs of pallor or jaundice.
Choice D rationale:
The correct choice is D.
When assessing a patient with suspected vitamin B12 deficiency anemia, it is crucial to examine the skin, mucous membranes, and eyes.
Pallor (pale skin) and jaundice (yellowing of the skin and eyes) are common signs of anemia, and these can be detected through the inspection of the skin, mucous membranes (such as the inside of the mouth), and the whites of the eyes (sclera)
These signs are indicative of an underlying health issue, and identifying them is essential for the diagnosis and management of anemia.
The patient is prescribed vitamin B12 supplementation.
What is the appropriate route and dosage of vitamin B12 for a patient with pernicious anemia or severe malabsorption?
Explanation
Choice A rationale:
Administering 500 mcg of cyanocobalamin intramuscularly daily for a week, then monthly for life is the appropriate route and dosage for a patient with pernicious anemia or severe malabsorption.
Intramuscular injection is the preferred route for patients with impaired absorption of vitamin B12, as it ensures direct absorption into the bloodstream.
The initial daily dose helps replenish depleted stores, and the monthly maintenance dose is required to prevent recurrence.
Choice B rationale:
Administering 1000 mcg of cyanocobalamin orally daily for a week, then weekly for a month, then monthly for life is not the best choice for patients with pernicious anemia or severe malabsorption.
Oral vitamin B12 is not effective in these cases because the underlying issue is the inability to absorb vitamin B12 from the gastrointestinal tract.
Intramuscular administration bypasses this problem.
Choice C rationale:
Administering 1000 mcg of cyanocobalamin intramuscularly daily for a week, then monthly for life is a reasonable option, but it is not as effective as the regimen described in choice A.
The initial daily dose is lower, and there is no weekly dosing phase to replenish stores quickly.
Choice D rationale:
Administering 2000 mcg of cyanocobalamin subcutaneously daily for a week, then monthly for life is not the preferred route for vitamin B12 supplementation in patients with pernicious anemia or severe malabsorption.
Intramuscular injection is the preferred route as it ensures better absorption, and subcutaneous injection may not be as effective.
What foods should the nurse encourage the client to consume to increase their vitamin B12 intake?
Explanation
Choice A rationale:
The nurse should encourage the client with vitamin B12 deficiency anemia to consume foods rich in vitamin B12.
Meat, poultry, fish, eggs, and fortified cereals are excellent sources of vitamin B12.
Including these foods in the diet can help increase vitamin B12 intake and support the treatment of the deficiency.
Choice B rationale:
Fruits and vegetables high in vitamin C are not directly related to increasing vitamin B12 intake.
Vitamin C is essential for iron absorption, but it does not provide vitamin B12.
Encouraging the consumption of vitamin C-rich foods is important for iron-deficiency anemia, not vitamin B12 deficiency anemia.
Choice C rationale:
Dairy products and nuts are not primary sources of vitamin B12.
While they offer other essential nutrients, they do not provide significant amounts of vitamin B12.
Therefore, they should not be the primary focus when trying to increase vitamin B12 intake.
Choice D rationale:
Foods high in iron and calcium, while important for overall health, are not the primary focus when addressing vitamin B12 deficiency anemia.
Iron and calcium-rich foods are more relevant to iron-deficiency anemia and bone health, respectively.
The primary focus for vitamin B12 deficiency anemia should be on foods rich in vitamin B12, as mentioned in choice A.
Which actions should the nurse include in the client's self-care plan to prevent recurrence of the deficiency? (Select three.)
Explanation
Choice A rationale:
Limit alcohol consumption is a crucial action to include in the client's self-care plan to prevent the recurrence of vitamin B12 deficiency anemia.
Excessive alcohol intake can interfere with the absorption of vitamin B12 in the body.
Alcohol can damage the lining of the stomach and the small intestine, where vitamin B12 is absorbed.
By limiting alcohol consumption, the client can improve their absorption of vitamin B12, reducing the risk of recurrence.
Choice C rationale:
Consuming foods high in vitamin C is another important action to prevent the recurrence of vitamin B12 deficiency anemia.
Vitamin C can enhance the absorption of vitamin B12 in the body.
Including vitamin C-rich foods in the diet can help improve the body's ability to absorb the vitamin B12 from dietary sources.
This is especially important for individuals who may have difficulty absorbing vitamin B12 due to underlying conditions.
Choice E rationale:
Monitoring for signs of infection is a relevant action in the self-care plan for preventing recurrence of vitamin B12 deficiency anemia.
Infections can lead to anemia by affecting the production of red blood cells.
By monitoring for signs of infection and promptly seeking medical treatment if any signs or symptoms arise, the client can reduce the risk of anemia caused or exacerbated by infections.
Choice B rationale:
Avoiding foods rich in vitamin B12 is not a recommended action for preventing the recurrence of vitamin B12 deficiency anemia.
In fact, it is counterproductive because the client with this deficiency should aim to increase their intake of vitamin B12-rich foods or supplements to correct the deficiency.
Choice D rationale:
Maintaining a diet low in iron is also not a recommended action for preventing the recurrence of vitamin B12 deficiency anemia.
Iron is essential for the production of red blood cells, and individuals with vitamin B12 deficiency anemia may have concurrent iron deficiency anemia.
Limiting iron intake can exacerbate the anemia and is not advisable.
What is an essential aspect of the client's treatment plan?
Explanation
Choice B rationale:
Treatment of underlying gastric disorders is an essential aspect of the client's treatment plan for vitamin B12 deficiency anemia when there are underlying gastric disorders contributing to the deficiency.
In such cases, the root cause of the deficiency is the impaired absorption of vitamin B12 due to gastric issues.
Simply providing vitamin B12 supplementation alone may not be effective because the absorption problem needs to be addressed.
Treating the underlying gastric disorders can improve the client's ability to absorb vitamin B12 from their diet or supplements, ultimately correcting the deficiency.
Choice A rationale:
Vitamin B12 supplementation alone may not be sufficient if there are underlying gastric disorders contributing to the deficiency.
While vitamin B12 supplementation is necessary to address the immediate deficiency, it does not address the root cause of the problem, which is the impaired absorption of vitamin B12 in the gastrointestinal tract.
Choice C rationale:
Intramuscular injections of iron are not indicated for the treatment of vitamin B12 deficiency anemia.
Iron is used to treat iron deficiency anemia, which is a separate condition from vitamin B12 deficiency anemia.
Using iron injections in a client with vitamin B12 deficiency anemia without iron deficiency could lead to iron overload and other complications.
Choice D rationale:
Folate supplementation is not the primary treatment for vitamin B12 deficiency anemia.
While folate (or folic acid) is essential for red blood cell production, it does not address the specific deficiency of vitamin B12.
Vitamin B12 and folate are related but distinct nutrients, and vitamin B12 supplementation is the primary treatment for vitamin B12 deficiency anemia.
Which of the following assessments should the nurse prioritize to monitor the effectiveness of treatment?
Explanation
Choice C rationale:
Regular blood tests to check hemoglobin and vitamin B12 levels should be prioritized to monitor the effectiveness of treatment for vitamin B12 deficiency anemia.
Monitoring hemoglobin levels can assess the improvement in anemia, while monitoring vitamin B12 levels can confirm that the deficiency is being adequately corrected.
Regular blood tests provide objective data on the client's response to treatment and help healthcare providers adjust the treatment plan if needed.
Choice A rationale:
Monitoring blood glucose levels is not a priority assessment for monitoring the effectiveness of treatment for vitamin B12 deficiency anemia.
While vitamin B12 deficiency can lead to neurological symptoms and affect glucose metabolism, the primary focus of monitoring in this context should be on anemia-related parameters, such as hemoglobin and vitamin B12 levels.
Choice B rationale:
Checking urine for protein is not a relevant assessment for monitoring the effectiveness of treatment for vitamin B12 deficiency anemia.
Proteinuria is a finding associated with kidney dysfunction and is not directly related to the evaluation of anemia or vitamin B12 deficiency.
Choice D rationale:
Measuring bone density is not a priority assessment for monitoring the effectiveness of treatment for vitamin B12 deficiency anemia.
Bone density assessment is typically used to evaluate bone health and the risk of osteoporosis, which is not a primary concern in the context of vitamin B12 deficiency anemia.
The focus should be on hematological parameters and neurological symptoms associated with the deficiency.
Hemolytic anemia
The patient asks, "Why do I have this condition?" Which response by the nurse is accurate?
Explanation
Choice A rationale:
Hemolytic anemia is not typically caused by infections.
Infections can cause other types of anemia, such as anemia of chronic disease, but not hemolytic anemia.
This choice is incorrect.
Choice B rationale:
This is the correct answer.
Hemolytic anemia is usually a result of genetic defects.
It can also be acquired through autoimmune conditions or exposure to certain drugs and toxins, but genetic defects are a common cause.
Genetic defects can lead to abnormal red blood cell shapes (e.g., sickle cell anemia) or defects in red blood cell membranes (e.g., hereditary spherocytosis), resulting in hemolysis.
Choice C rationale:
Exposure to toxins is not the primary cause of hemolytic anemia.
While some toxins can cause hemolysis, they are not the leading cause of this condition.
This choice is incorrect.
Choice D rationale:
Mechanical trauma is not the primary reason for developing hemolytic anemia.
While physical trauma can lead to the rupture of red blood cells (e.g., in cases of traumatic hemolysis), it is not the primary cause of hemolytic anemia.
This choice is incorrect.
Explanation
Choice A rationale:
This choice is incorrect.
Choice B rationale:
Infections can cause anemia, but they do not typically cause hemolytic anemia.
Infections can lead to anemia of chronic disease or anemia due to decreased production of red blood cells, but these are different from hemolytic anemia.
This choice is incorrect.
Choice C rationale:
Hemolytic anemia is primarily characterized by the destruction of red blood cells, which may release iron into the bloodstream, but this is a consequence of hemolysis, not the cause.
This choice is incorrect.
Choice D rationale:
This is the correct answer.
Hemolytic anemia results in the destruction of red blood cells due to oxidative stress.
Red blood cells are exposed to oxidative damage, which leads to their premature destruction in the bloodstream, causing anemia.
Which complications should the nurse include in the teaching? Select all that apply.
Explanation
Choice A rationale:
Increased risk of thrombosis is a potential complication of hemolytic anemia.
When red blood cells are destroyed, they release substances that can promote blood clot formation, increasing the risk of thrombosis.
This choice is correct.
Choice B rationale:
Decreased iron utilization is not a typical complication of hemolytic anemia.
Hemolysis can release iron into the bloodstream, but it does not lead to decreased iron utilization.
This choice is incorrect.
Choice C rationale:
Impaired erythropoiesis can be a complication of hemolytic anemia.
When red blood cells are rapidly destroyed, the bone marrow may struggle to keep up with the demand for new red blood cell production, leading to impaired erythropoiesis.
This choice is correct.
Choice D rationale:
Elevated haptoglobin levels are not typically seen in hemolytic anemia.
Haptoglobin levels may decrease in response to increased hemolysis, as haptoglobin binds to free hemoglobin released from ruptured red blood cells.
This choice is incorrect.
Choice E rationale:
Higher susceptibility to infections is a potential complication of hemolytic anemia.
The destruction of red blood cells can weaken the immune system and make the individual more susceptible to infections.
This choice is correct.
Which clinical manifestation is consistent with intravascular hemolysis?
Explanation
Choice A rationale:
Elevated bilirubin levels.
Elevated bilirubin levels are not a specific clinical manifestation of intravascular hemolysis.
Bilirubin levels may be elevated in various types of anemia, but it is not a characteristic sign of intravascular hemolysis.
Choice B rationale:
Hemoglobinuria.
Hemoglobinuria is a clinical manifestation consistent with intravascular hemolysis.
When red blood cells are destroyed within blood vessels, hemoglobin is released into the bloodstream, and it can be filtered by the kidneys and excreted in the urine, leading to hemoglobinuria.
Choice C rationale:
Splenomegaly.
Splenomegaly can occur in some types of anemia, but it is not a specific clinical manifestation of intravascular hemolysis.
It may be more commonly associated with conditions like hereditary spherocytosis or thalassemia.
Choice D rationale:
Increased ferritin levels.
Increased ferritin levels are not a specific clinical manifestation of intravascular hemolysis.
Ferritin is a marker of iron storage in the body and is not directly related to the destruction of red blood cells.
Explanation
"Bilirubin is primarily excreted through the kidneys." This statement is not accurate.
While some bilirubin is excreted through the kidneys, the primary route of bilirubin excretion is through the liver and bile.
Bilirubin is converted to conjugated bilirubin in the liver, which is then excreted in bile.
Choice B rationale:
"Bilirubin is stored in the liver as hemosiderin." This statement is incorrect.
Hemosiderin is not a form of bilirubin but rather a storage form of iron in the liver and other tissues.
Choice C rationale:
"Bilirubin is recycled into iron and biliverdin." This statement is not accurate.
Bilirubin is primarily metabolized in the liver and conjugated before being excreted in bile.
It does not get recycled into iron and biliverdin.
Choice D rationale:
"Bilirubin is conjugated in the liver and excreted in bile." This is the correct answer.
Bilirubin is produced from the breakdown of heme in red blood cells and is then processed in the liver, where it is conjugated (combined with glucuronic acid) to form conjugated bilirubin.
Conjugated bilirubin is excreted in bile and eventually eliminated from the body in feces.
A nurse is caring for a client with hemolytic anemia.
The client presents with pallor, fatigue, tachycardia, and jaundice.
Which of the following additional clinical manifestations should the nurse anticipate in this client?
Explanation
"I have noticed that my urine has become very dark lately." Dark urine is a common clinical manifestation of hemolysis, as it indicates the presence of hemoglobin in the urine, known as hemoglobinuria.
This is a result of the breakdown of red blood cells and release of hemoglobin into the bloodstream.
Choice B rationale:
"My abdomen feels swollen and uncomfortable." Abdominal discomfort or swelling is not a specific clinical manifestation of hemolytic anemia.
It may be associated with conditions like splenomegaly but is not a characteristic sign of hemolysis.
Choice C rationale:
"I have been experiencing painful episodes in my bones." Painful episodes in the bones are not typically associated with hemolytic anemia.
Bone pain may be related to other conditions but is not a direct result of hemolysis.
Choice D rationale:
"I have been having severe headaches and chest pain." Severe headaches and chest pain are not specific clinical manifestations of hemolytic anemia.
These symptoms may have other causes and should be evaluated separately.
The nurse reviews the laboratory results and finds a low hemoglobin level, normal mean corpuscular volume (MCV), and elevated reticulocyte count.
Which additional laboratory findings would be consistent with this diagnosis?
Explanation
Choice A rationale:
Elevated serum bilirubin levels can be seen in hemolytic anemia due to increased breakdown of red blood cells.
However, it is not specific to hemolytic anemia and can occur in other conditions as well.
Choice B rationale:
Haptoglobin is a protein that binds to free hemoglobin released from the destruction of red blood cells.
In hemolytic anemia, there is increased hemolysis, leading to a decrease in haptoglobin levels as it gets consumed to bind to the released hemoglobin.
This is consistent with the clinical picture described in the question.
Choice C rationale:
Lactate dehydrogenase (LDH) is an enzyme found in various tissues, including red blood cells.
Elevated LDH levels can be seen in hemolytic anemia due to the release of LDH from damaged red blood cells.
However, LDH elevation is not specific to hemolytic anemia and can occur in other conditions.
Choice D rationale:
The absence of abnormalities in the peripheral blood smear does not rule out hemolytic anemia.
Some forms of hemolytic anemia may not show distinct abnormalities in the appearance of red blood cells on a peripheral blood smear.
A nurse is providing education to a group of clients with different types of hemolytic anemia.
Which types of hemolytic anemia are associated with abnormalities in the shape or structure of red blood cells? (Select all that apply)
Explanation
Hereditary spherocytosis.
C. Sickle cell anemia.
D. Thalassemia intermedia.
E. Immune-mediated hemolytic anemia.
Choice A rationale:
Hereditary spherocytosis is a genetic disorder characterized by abnormal red blood cell membrane proteins, leading to a spherical shape instead of the normal biconcave disc shape.
Choice C rationale:
Sickle cell anemia is caused by a mutation in the hemoglobin gene, leading to the formation of abnormal hemoglobin (hemoglobin S) that causes red blood cells to take on a sickle shape when oxygen levels are low.
Choice D rationale:
Thalassemia intermedia is a form of thalassemia characterized by the production of abnormal hemoglobin molecules, leading to the destruction of red blood cells and potential changes in their structure.
Choice E rationale:
Immune-mediated hemolytic anemia can result in the production of autoantibodies that attack red blood cells, leading to changes in their structure and function.
Choice B rationale:
G6PD deficiency is not associated with abnormalities in the shape or structure of red blood cells.
Instead, it is characterized by red blood cell destruction due to a lack of the enzyme glucose-6-phosphate dehydrogenase.
The nurse suspects immune-mediated hemolysis.
Which diagnostic test should the nurse prioritize to confirm this suspicion?
Explanation
Choice A rationale:
A complete blood count (CBC) with differential can provide information about the overall red blood cell count and indices but may not confirm the presence of immune-mediated hemolysis.
Choice B rationale:
A peripheral blood smear can show abnormalities in the shape and structure of red blood cells but may not confirm the presence of immune-mediated hemolysis or identify the underlying cause.
Choice D rationale:
Serum bilirubin and haptoglobin levels can provide indirect evidence of hemolysis, but they do not confirm the presence of immune-mediated hemolysis or identify the underlying cause.
Choice C rationale:
The direct antiglobulin test (DAT), also known as the Coombs test, is used to detect the presence of antibodies or complement proteins on the surface of red blood cells.
A positive DAT result indicates immune-mediated hemolysis, confirming the suspicion raised by the clinical presentation of pallor, fatigue, and splenomegaly.
This test is crucial for diagnosing the specific type of immune-mediated hemolytic anemia and guiding further management.
The client's laboratory results show low hemoglobin, low hematocrit, normal MCV, and high reticulocyte count.
Which of the following statements by the client indicates a need for further education regarding their condition?
Explanation
Choice A rationale:
The statement, "My reticulocyte count is higher than normal," indicates that the client has an understanding of their condition.
In hemolytic anemia, the bone marrow releases more reticulocytes (immature red blood cells) in response to the low hemoglobin levels to compensate for the destruction of red blood cells.
Choice B rationale:
The statement, "I have a lower-than-normal hematocrit level," is a correct assessment of the client's condition.
Hemolytic anemia typically results in low hematocrit levels due to the decreased number of red blood cells.
Choice C rationale:
The statement, "My MCV is within the normal range," is incorrect.
In hemolytic anemia, MCV (mean corpuscular volume) is often elevated because the remaining red blood cells are larger than normal.
This statement indicates a need for further education as it reflects a misunderstanding of the laboratory results.
Choice D rationale:
The statement, "My hemoglobin level falls within the expected range," is incorrect.
Hemolytic anemia typically results in low hemoglobin levels due to the destruction of red blood cells.
This statement indicates a need for further education as it reflects a misunderstanding of the laboratory results.
Which aspect of the patient's history should the nurse prioritize?
Explanation
Choice A rationale:
The statement, "I'm feeling so weak lately," is important information, but it does not prioritize the assessment.
Weakness is a common symptom of anemia, but in a patient with suspected hemolytic anemia, obtaining a family history of hemolytic disorders is more critical.
Choice B rationale:
The statement, "I had a blood transfusion a few years ago," is relevant to the patient's history but does not take priority over obtaining information about the family history of hemolytic disorders.
Choice C rationale:
The statement, "I think I might have an autoimmune disorder," is relevant and should be explored further, but it does not take priority over obtaining a family history of hemolytic disorders.
Choice D rationale:
The statement, "My family has a history of hemolytic disorders," is the most crucial aspect of the patient's history to prioritize.
Hemolytic disorders often have a genetic component, so family history can provide valuable information for diagnosis and management.
Explanation
Choice A rationale:
The statement, "My skin looks paler than usual," is a valid physical examination finding, but it is a general symptom of anemia and not specific to hemolytic anemia.
Other types of anemia can also cause pale skin.
Choice B rationale:
The statement, "I've been having chest pain occasionally," is important to assess, but it is not a specific physical examination finding related to hemolytic anemia.
Chest pain may have various causes, and additional information is needed to determine its significance.
Choice C rationale:
The statement, "I've noticed my urine is getting darker," is a specific physical examination finding that is highly relevant to hemolytic anemia.
Dark urine can result from the breakdown of red blood cells and the release of hemoglobin into the urine, a characteristic feature of hemolytic anemia.
Choice D rationale:
The statement, "I've been experiencing abdominal pain," is important to assess, but it is not a specific physical examination finding related to hemolytic anemia.
Abdominal pain can have various causes, and further evaluation is needed to determine its association with the patient's condition.
Which self-care instructions should the nurse include? (Select all that apply)
Explanation
Choice A rationale:
The nurse should instruct the patient to "Avoid exposure to infections" because patients with hemolytic anemia are at an increased risk of infection due to their compromised immune system.
Hemolytic anemia can result in the destruction of red blood cells, leading to a decreased ability to transport oxygen and an increased susceptibility to infections.
Choice B rationale:
Instructing the patient to "Stay warm in cold temperatures" is essential because cold temperatures can exacerbate symptoms in individuals with hemolytic anemia.
Cold exposure can lead to vasoconstriction, which can worsen anemia-related symptoms by reducing blood flow and oxygen delivery to tissues.
Choice C rationale:
The statement "Take over-the-counter pain medications as needed" is not a recommended self-care instruction for hemolytic anemia.
Pain medications will not address the underlying cause of the condition, and their use should be guided by a healthcare provider to avoid potential complications.
Choice D rationale:
"Limit your fluid intake to prevent dehydration" is not an appropriate self-care instruction for hemolytic anemia.
Dehydration can worsen the condition by increasing the concentration of red blood cells in the blood, potentially leading to further hemolysis.
Encouraging adequate hydration is generally important unless there are specific contraindications.
Choice E rationale:
Instructing the patient to "Report any jaundice or dark urine to your healthcare provider" is crucial because jaundice and dark urine are common signs of hemolysis in hemolytic anemia.
These symptoms indicate an increased breakdown of red blood cells and should be promptly reported to the healthcare provider for evaluation and management.
Explanation
Choice A rationale:
Administering blood transfusions as ordered is a treatment for hemolytic anemia to replace the deficient red blood cells.
However, it is not a nursing intervention aimed at preventing complications; it is part of the treatment plan.
Choice B rationale:
Providing oxygen therapy as prescribed is a supportive measure to improve tissue oxygenation, which is essential in managing hemolytic anemia.
However, it is not a specific nursing intervention aimed at preventing complications; it is part of the patient's overall care.
Choice C rationale:
Monitoring for fluid and electrolyte imbalances is a crucial nursing intervention in patients with hemolytic anemia.
Hemolysis can lead to the release of hemoglobin into the bloodstream, which can, in turn, cause kidney damage and electrolyte imbalances.
Monitoring and managing these imbalances are essential in preventing complications.
Choice D rationale:
Advising the patient to avoid physical activity is not a specific nursing intervention for hemolytic anemia.
While excessive physical activity may exacerbate symptoms, it is not a primary intervention for preventing complications associated with the condition.
Explanation
Choice A rationale:
"To stimulate the production of fetal hemoglobin" is not the purpose of corticosteroids in the treatment and management of hemolytic anemia.
Corticosteroids are primarily used to suppress the immune response and reduce the destruction of red blood cells by autoantibodies.
Fetal hemoglobin is typically produced during fetal development and is not a target of corticosteroid therapy.
Choice B rationale:
The correct purpose of corticosteroids in hemolytic anemia is "To block the binding of autoantibodies to RBCs." Corticosteroids, such as prednisone, are often prescribed to reduce the autoimmune response that leads to the destruction of red blood cells.
By inhibiting the binding of autoantibodies to red blood cells, corticosteroids help to decrease hemolysis and improve anemia.
Choice C rationale:
"To surgically remove the spleen" is a treatment option in some cases of hemolytic anemia, particularly when the spleen is enlarged and contributing to the destruction of red blood cells.
However, it is not the primary purpose of corticosteroid therapy.
Choice D rationale:
"To improve tissue oxygenation" is not the primary purpose of corticosteroids in the treatment and management of hemolytic anemia.
While corticosteroids may indirectly improve tissue oxygenation by reducing hemolysis, their primary role is to modulate the autoimmune response and reduce the destruction of red blood cells.
Sickle Cell Disease
The patient asks, "Why do my red blood cells become sickle-shaped?" Which response by the nurse is most accurate?
Explanation
Choice A rationale:
Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the HBB gene, leading to the production of abnormal hemoglobin called hemoglobin S (HbS)
This abnormal hemoglobin causes red blood cells to become sickle-shaped when exposed to low oxygen levels, which is a hallmark of SCD.
The nurse's response accurately reflects the genetic basis of this condition.
Choice B rationale:
This choice is incorrect.
Sickle-shaped red blood cells in SCD are not the result of an autoimmune reaction.
Choice C rationale:
This choice is incorrect.
Sickle-shaped red blood cells are not caused by a viral infection.
Choice D rationale:
This choice is incorrect.
Diet and lifestyle choices do not contribute to the sickle shape of red blood cells in SCD.
The client asks the nurse for an explanation.
Which response by the nurse is correct?
Explanation
Choice A rationale:
Jaundice and gallstones are common complications of sickle cell disease (SCD) because of hemolysis, which is the destruction of abnormal red blood cells.
The breakdown of these cells releases bilirubin, leading to jaundice, and can also result in the formation of gallstones.
Choice B rationale:
This choice is incorrect.
Jaundice and gallstones in SCD are not caused by excessive iron intake in the diet.
Choice C rationale:
This choice is incorrect.
Allergic reactions to foods do not lead to jaundice and gallstones in SCD.
Choice D rationale:
This choice is incorrect.
Jaundice and gallstones in SCD do not result from an overproduction of normal red blood cells.
Select all that apply:
Explanation
Choice A rationale:
Patients with sickle cell disease (SCD) have an increased risk of infection due to the compromised immune function associated with the disease.
SCD can lead to functional asplenia, making individuals more susceptible to infections, particularly those caused by encapsulated bacteria.
Choice B rationale:
Hypoxia (lack of oxygen) and ischemia (reduced blood flow) are common complications of SCD.
The sickle-shaped red blood cells can obstruct blood vessels, leading to reduced oxygen delivery to tissues (hypoxia) and tissue damage due to impaired blood flow (ischemia)
Choice C rationale:
Blood clot formation is a known complication of SCD.
The altered shape of sickle cells can lead to the blockage of blood vessels, causing painful vaso-occlusive crises and increasing the risk of clot formation.
Choice D rationale:
This choice is incorrect.
Reduced risk of stroke is not associated with SCD.
In fact, individuals with SCD may have an increased risk of stroke due to the potential for vasculopathy and clot formation.
Choice E rationale:
Reduced adhesion of red blood cells (RBCs) to the endothelium is not a typical feature of SCD.
In fact, the adhesion of sickle cells to the endothelium is one of the pathophysiological mechanisms leading to vaso-occlusive events in SCD.
The nurse recognizes this as a:
Explanation
Choice A rationale:
A severe episode of pain in a client with sickle cell disease (SCD) is indicative of a sickle cell crisis.
Sickle cell crisis is a common complication of SCD, characterized by sudden, severe pain due to the formation of sickle-shaped red blood cells that obstruct blood flow in small blood vessels.
This vaso-occlusion leads to tissue ischemia and pain in various parts of the body.
It is a hallmark symptom of SCD and requires prompt management, typically with pain medications and hydration.
Choice B rationale:
Hemolysis event is not the correct choice in this context.
Hemolysis refers to the premature destruction of red blood cells, which can occur in SCD but does not directly correlate with the severe pain experienced during a sickle cell crisis.
Choice C rationale:
Jaundice episode is not the correct choice in this context either.
Jaundice, characterized by yellowing of the skin and eyes, can occur in individuals with SCD due to the breakdown of hemoglobin from ruptured red blood cells, but it does not specifically address the severe pain described in the question.
Choice D rationale:
Inflammatory reaction is not the correct choice for this scenario.
While inflammation can play a role in the pathophysiology of SCD, it does not directly describe the acute and severe pain experienced during a sickle cell crisis.
Which of the following is a priority problem to identify in this patient?
Explanation
Choice A rationale:
Skin rash is not the priority problem to identify in a patient with sickle cell disease (SCD)
While skin manifestations can occur in SCD, such as leg ulcers, they are not typically the most critical issue for these patients.
Pain and discomfort related to sickle cell crisis, vaso-occlusion, and tissue ischemia take precedence as a priority.
Choice B rationale:
Increased energy levels are not a priority problem in a patient with SCD.
In fact, patients with SCD often experience fatigue and weakness, especially during sickle cell crises.
Identifying and managing pain and discomfort are more crucial for the patient's well-being.
Choice C rationale:
Pain and discomfort are the priority problems to identify in a patient with SCD.
Sickle cell crises can lead to excruciating pain in various parts of the body, and prompt management of this pain is essential to improve the patient's quality of life and prevent complications.
Choice D rationale:
Improved lung function is not the priority problem to identify in a patient with SCD.
While lung complications can occur in SCD (e.g., acute chest syndrome), addressing pain and discomfort is more urgent and essential for the patient's immediate well-being.
.
The patient reports pain in various areas, including the chest and joints.
What other clinical manifestations of SCD should the nurse be vigilant for?
Explanation
Choice A rationale:
"I've been experiencing fever and chills recently." Fever and chills can be associated with various illnesses and infections but are not specific clinical manifestations of sickle cell disease (SCD)
The primary concern in SCD is vaso-occlusion, anemia, and pain, which should be monitored closely.
Choice B rationale:
"I've noticed a yellowing of my skin and eyes." Yellowing of the skin and eyes (jaundice) can occur in SCD due to the breakdown of hemoglobin, but it is not directly related to the pain in the chest and joints described in the question.
Choice C rationale:
"I've been having trouble breathing and feeling weak." While respiratory symptoms and weakness can occur in SCD, they are not the primary clinical manifestations associated with pain in the chest and joints.
Painful erections and impotence are more directly related to SCD complications, such as priapism, which is a medical emergency and requires prompt attention.
Choice D rationale:
"I've had painful erections and impotence." Painful erections and impotence are potential complications of sickle cell disease (SCD), particularly due to priapism, a condition where blood becomes trapped in the penis.
This can lead to severe pain and, if not treated promptly, permanent erectile dysfunction.
Therefore, the nurse should be vigilant for these clinical manifestations to address them promptly.
The nurse is concerned about potential complications.
Which additional clinical manifestations should the nurse assess for?
Explanation
Choice A rationale:
"I've been having vision problems lately." Rationale: Vision problems are not directly associated with complications of sickle cell disease (SCD)
SCD primarily affects the blood and vascular system, leading to symptoms such as anemia, pain crises, and organ damage.
Vision problems may be caused by other underlying conditions, but they are not a typical manifestation of SCD complications.
Choice B rationale:
"I've had delayed growth in my child." Rationale: Delayed growth in a child could be associated with SCD, as it may be a result of chronic anemia and inadequate oxygen delivery to tissues.
However, it is not a direct clinical manifestation of complications.
Other more common complications, such as pain crises, acute chest syndrome, or organ damage, should be assessed first to determine the extent of the disease's impact on the patient's health.
Choice C rationale:
"I had a stroke a few years ago." Rationale: This statement is significant because stroke is a known complication of sickle cell disease.
SCD can lead to the occlusion of blood vessels, including those in the brain, resulting in stroke.
Therefore, the nurse should assess for any neurological deficits and gather more information about the stroke episode to assess its severity and potential impact on the patient's current condition.
Choice D rationale:
"I'm experiencing chest pain, fever, and cough." Rationale: Chest pain, fever, and cough are indicative of acute chest syndrome (ACS), which is a severe complication of SCD.
ACS can lead to respiratory distress and is considered a medical emergency.
The presence of these symptoms warrants immediate assessment and intervention, making choice D the correct answer.
A nurse is performing a comprehensive assessment of a patient with SCD.
Which aspects of the nursing assessment should the nurse prioritize?
Explanation
Choice A rationale:
Gathering information about the patient's personal and family history of SCD or trait.
Rationale: Understanding the patient's personal and family history of SCD or the sickle cell trait is crucial in assessing the risk and potential complications associated with the disease.
It helps identify genetic factors, family support, and the likelihood of the patient experiencing complications related to SCD.
Choice B rationale:
Assessing the location, intensity, and duration of pain.
Rationale: Pain is a hallmark symptom of SCD, and assessing the location, intensity, and duration of pain is essential in managing and monitoring the patient's condition.
This information helps healthcare providers determine the severity of the pain crisis, make treatment decisions, and assess treatment effectiveness.
Choice D rationale:
Inspecting for signs of anemia and jaundice during the physical examination.
Rationale: Anemia and jaundice are common clinical manifestations of SCD.
Anemia results from the destruction of sickled red blood cells, while jaundice occurs due to the breakdown of these cells and the release of bilirubin.
Assessing for signs of anemia and jaundice, such as pallor and yellowing of the skin and sclera, is essential in monitoring the patient's overall health.
Choice C rationale:
Measuring the patient's temperature, pulse, and blood pressure.
Rationale: While vital signs are important components of a nursing assessment, they are not specific to sickle cell disease.
Monitoring vital signs is a routine practice in healthcare but may not provide specific information about the disease's complications or progression.
Choice E rationale:
Conducting genetic testing to confirm the diagnosis of SCD.
Rationale: Genetic testing is essential for diagnosing sickle cell disease, but it is typically performed before the patient is confirmed to have SCD.
Once a diagnosis is established, genetic testing may not be necessary for routine assessment.
It is crucial in the initial diagnostic phase but is not a part of ongoing nursing assessment.
Which laboratory test is essential for confirming the diagnosis and identifying the presence of abnormal hemoglobins?
Explanation
Choice A rationale:
Complete blood count (CBC)
Rationale: A CBC is a standard blood test that provides information about the number and types of blood cells in the patient's circulation.
While it can help diagnose anemia, it does not confirm the presence of abnormal hemoglobins or sickle cell disease.
Choice A is not the essential test for confirming the diagnosis.
Choice B rationale:
Peripheral blood smear.
Rationale: A peripheral blood smear can be useful in assessing the morphology of red blood cells, but it may not be specific enough to confirm the presence of abnormal hemoglobins or sickle cell disease definitively.
It can provide supportive evidence but is not the primary diagnostic test.
Choice C rationale:
Solubility test or sickling test.
Rationale: The solubility test or sickling test is essential for confirming the diagnosis of sickle cell disease and identifying the presence of abnormal hemoglobins, specifically hemoglobin S (HbS)
This test is the gold standard for diagnosing SCD, making choice C the correct answer.
Choice D rationale:
Imaging studies, such as a chest x-ray.
Rationale: Imaging studies like chest x-rays are not used as primary diagnostic tools for sickle cell disease.
They may be employed to assess complications such as acute chest syndrome or other respiratory issues associated with SCD, but they do not confirm the diagnosis or identify abnormal hemoglobins.
What is the primary purpose of hemoglobin electrophoresis in the diagnostic workup?
Explanation
Choice A rationale:
Hemoglobin electrophoresis is not primarily used to measure the number and size of red blood cells.
It focuses on the types of hemoglobin present in the blood, not their quantity or size.
Choice B rationale:
The primary purpose of hemoglobin electrophoresis in the diagnostic workup for sickle cell disease (SCD) is to identify the presence and amount of abnormal hemoglobins.
This test helps diagnose and differentiate various types of hemoglobinopathies, including SCD.
Abnormal hemoglobins like hemoglobin S (HbS) are characteristic of SCD.
Choice C rationale:
Hemoglobin electrophoresis does not expose a blood sample to a deoxygenating agent.
Instead, it separates hemoglobin molecules based on their electrical charge, which is useful for identifying abnormal hemoglobins associated with SCD.
Choice D rationale:
Hemoglobin electrophoresis does not analyze the DNA of a blood sample.
It primarily focuses on the characterization of hemoglobin types and their proportions within the blood.
The patient is experiencing severe pain and requests pain relief.
Which nursing intervention is appropriate for managing the patient's pain?
Explanation
Choice A rationale:
Administering nonsteroidal anti-inflammatory drugs (NSAIDs) may be part of the pain management plan for SCD, but it is not the most appropriate immediate intervention for severe pain.
NSAIDs can be used for mild to moderate pain, but severe pain in SCD often requires stronger analgesics.
Choice B rationale:
Providing emotional support and distraction techniques is appropriate for managing the patient's pain.
SCD pain crises can be excruciating, and emotional support, along with distraction techniques, can help the patient cope with the pain.
These interventions can be used alongside pain medications.
Choice C rationale:
Suggesting stem cell transplantation to cure the disease is not an appropriate immediate intervention for managing severe pain.
Stem cell transplantation is a complex and long-term treatment option for SCD, and it does not provide immediate relief from pain.
Choice D rationale:
Encouraging the patient to avoid triggers such as cold and stress is important for preventing pain crises in SCD, but it is not the most appropriate immediate intervention for managing severe pain during a crisis.
Pain relief measures should be prioritized to alleviate the patient's suffering.
What is the purpose of oxygen therapy in the management of SCD?
Explanation
Choice A rationale:
Oxygen therapy in the management of SCD is primarily aimed at preventing tissue hypoxia, not providing relief from severe pain.
SCD patients may experience pain due to tissue ischemia caused by the sickling of red blood cells, and oxygen can help prevent this by increasing the oxygen-carrying capacity of the blood.
Choice B rationale:
The primary purpose of oxygen therapy in the management of SCD is to prevent tissue hypoxia.
SCD patients are at risk of vaso-occlusive crises and tissue damage due to reduced oxygen delivery.
Supplemental oxygen helps maintain adequate tissue oxygenation and reduces the risk of complications.
Choice C rationale:
Oxygen therapy is not administered for the purpose of directly administering analgesics.
Analgesics are typically administered separately to manage pain in SCD patients.
Choice D rationale:
Oxygen therapy is not used to induce relaxation.
Its main goal is to improve oxygen saturation and prevent tissue hypoxia in SCD patients.
A nurse is educating a patient with sickle cell disease (SCD) and their family about the treatment and management of the condition.
Which interventions should the nurse include in the education and counseling plan? (Select three)
Explanation
Choice A rationale:
Medication adherence is essential in the treatment and management of sickle cell disease (SCD)
Patients with SCD often require medications such as hydroxyurea to reduce the frequency of painful crises and other complications.
Non-adherence to medications can lead to worsened outcomes and increased morbidity.
Educating the patient and their family about the importance of taking medications as prescribed is crucial.
Choice B rationale:
Avoidance of cold and altitude is important for patients with SCD because exposure to cold temperatures and high altitudes can trigger vaso-occlusive crises.
Cold can cause red blood cells to sickle more easily, leading to pain and tissue damage.
Altitude can result in lower oxygen levels in the blood, exacerbating the risk of sickling.
Educating the patient and their family about these environmental factors and strategies to minimize exposure is essential for SCD management.
Choice E rationale:
Providing emotional support and coping strategies is a crucial component of managing SCD.
Patients with SCD often experience chronic pain, frequent hospitalizations, and a reduced quality of life.
Emotional support can help them cope with the physical and emotional challenges associated with the disease.
Teaching patients and their families how to manage stress, anxiety, and depression can improve their overall well-being.
Choice C rationale:
Blood transfusion is not a first-line treatment for all SCD patients.
It is typically reserved for specific indications, such as severe anemia or acute complications like stroke.
Stem cell transplantation (Choice D) is a potential curative treatment for some individuals with SCD, but it is not applicable to all patients due to factors like donor availability and eligibility.
Therefore, Choices C and D are not universally applicable and may not be included in the education and counseling plan for all SCD patients.
Choice D rationale:
Stem cell transplantation is not recommended as a treatment for all SCD patients.
It is considered a high-risk procedure with potential complications, and its suitability depends on factors such as patient age, disease severity, and the availability of a suitable donor.
Therefore, it is not included as a standard intervention in the education and counseling plan for all SCD patients.
What should the nurse monitor for during and after the transfusion to ensure the patient's safety?
Explanation
Choice A rationale:
Monitoring for signs of transfusion reaction is a critical nursing responsibility during and after a blood transfusion.
Transfusion reactions, such as fever, chills, rash, or dyspnea, can occur due to various factors, including compatibility issues or bacterial contamination of the blood product.
Detecting these signs promptly allows for immediate intervention, including stopping the transfusion and providing appropriate treatment.
This ensures the patient's safety and well-being during the transfusion process.
Choice B rationale:
Monitoring the patient's response to music therapy is not a standard nursing assessment during or after a blood transfusion.
While music therapy can have benefits in managing pain and anxiety, it is not directly related to the safety of the transfusion process.
Choice C rationale:
Monitoring the patient's fluid intake and output is essential in many clinical situations, but it is not specifically related to the safety of a blood transfusion.
This parameter is more relevant in assessing the patient's hydration status and renal function.
Choice D rationale:
Monitoring the patient's emotional state is important for overall patient care, but it is not a primary concern during and immediately after a blood transfusion.
The focus during this time should be on detecting any adverse reactions or complications related to the transfusion itself.
What is the significance of an elevated serum ferritin level in a patient with SCD?
Explanation
Choice C rationale:
An elevated serum ferritin level in a patient with sickle cell disease (SCD) may signal iron overload.
Iron overload is a potential complication of chronic blood transfusions, which are often required in SCD to treat anemia and prevent complications.
Excessive iron accumulation can lead to organ damage, particularly in the liver, heart, and endocrine glands.
Monitoring and managing iron levels, including serum ferritin, are essential in SCD patients who receive regular transfusions.
Choice A rationale:
An elevated serum ferritin level does not indicate adequate iron stores.
In fact, it suggests the opposite, as it implies an excess of stored iron in the body.
Choice B rationale:
An elevated serum ferritin level is not indicative of iron deficiency anemia.
Iron deficiency anemia is characterized by low serum ferritin levels, as ferritin stores are depleted in this condition.
Choice D rationale:
An elevated serum ferritin level does not reflect normal hemoglobin levels.
Ferritin is a marker of iron storage and does not directly indicate the hemoglobin level, which measures the oxygen-carrying capacity of red blood cells.
.
Hemophilia
Which statement by one of the parents indicates a need for further teaching?
Explanation
Choice A rationale:
Hemophilia A and hemophilia B are both types of hemophilia, but hemophilia A is actually less common than hemophilia B.
The prevalence of hemophilia A is about 1 in 5,000 males, whereas hemophilia B occurs in about 1 in 25,000 males.
Therefore, this statement is incorrect.
Choice B rationale:
Hemophilia is not inherited through a defective gene on the Y chromosome.
Hemophilia is an X-linked recessive genetic disorder, which means it is caused by a mutation in genes located on the X chromosome, not the Y chromosome.
This statement is incorrect.
Choice C rationale:
This statement is correct.
Males inherit hemophilia from their mothers who carry the defective gene on one of their X chromosomes.
However, it's important to note that females can also be carriers of the gene and can pass it on to their sons.
This statement does not indicate a need for further teaching.
Choice D rationale:
This statement is incorrect.
While it is very rare for females to have hemophilia, it is not impossible.
Females can inherit hemophilia if they have two affected X chromosomes or if they inherit one affected X chromosome and one affected Y chromosome.
Therefore, this statement does not indicate a need for further teaching.
Which response by the nurse is accurate?
Explanation
Choice A rationale:
Hemophilia A is indeed caused by a mutation in the F8 gene, which encodes factor VIII.
Factor VIII is essential for blood clotting, and mutations in this gene lead to a deficiency or dysfunction of factor VIII, resulting in hemophilia A.
This response provides accurate information about the cause of the condition.
Choice B rationale:
Hemophilia A is not caused by a mutation in the F9 gene, which encodes factor IX.
Factor IX deficiency is associated with hemophilia B, not hemophilia A.
This statement is incorrect.
Choice C rationale:
Hemophilia A is not caused by a mutation in the Y chromosome.
As mentioned earlier, it is caused by a mutation in the F8 gene on the X chromosome.
This statement is incorrect.
Choice D rationale:
Hemophilia A is not caused by a deficiency of vitamin K.
Vitamin K deficiency can lead to bleeding disorders, but it is not the cause of hemophilia A.
This statement is incorrect.
Which clinical manifestations should the nurse expect to find? (Select all that apply.)
Explanation
Choice A rationale:
Easy bruising is a common clinical manifestation of hemophilia.
Patients with hemophilia have difficulty forming blood clots, which makes them prone to bleeding into the soft tissues, leading to easy bruising.
This choice is correct.
Choice B rationale:
Hematuria (blood in the urine) is not a typical clinical manifestation of hemophilia.
Hemorrhaging in the urinary tract is uncommon in hemophilia, so this choice is incorrect.
Choice C rationale:
Joint pain and swelling are characteristic clinical manifestations of hemophilia.
Bleeding into the joints can cause pain, swelling, and limited range of motion.
This choice is correct.
Choice D rationale:
Elevated factor VIII levels are not an expected clinical manifestation of hemophilia.
In fact, individuals with hemophilia have reduced levels of factor VIII due to the genetic mutation that causes the condition.
This choice is incorrect.
Choice E rationale:
Spontaneous nosebleeds are a common clinical manifestation of hemophilia.
The fragile blood vessels in the nose can rupture easily, leading to spontaneous nosebleeds.
This choice is correct.
Which complication should the nurse prioritize in the client's care plan?
Explanation
Choice A rationale:
Hypertension is not a common complication of hemophilia.
While bleeding disorders like hemophilia can lead to bleeding in various body systems, hypertension is not directly associated with hemophilia.
Therefore, it is not a priority in the care plan for a client with hemophilia.
Choice B rationale:
Deep vein thrombosis (DVT) is a condition characterized by the formation of blood clots in deep veins, which can lead to serious complications.
While individuals with hemophilia are at an increased risk of bleeding, they are not at an increased risk of DVT.
In fact, individuals with hemophilia often have difficulty forming blood clots, making DVT less likely in this population.
Therefore, it is not a priority in the care plan for a client with hemophilia.
Choice D rationale:
Hyperlipidemia refers to high levels of lipids (fats) in the blood, such as cholesterol and triglycerides.
It is not a common complication of hemophilia, and there is no direct link between hemophilia and hyperlipidemia.
Therefore, it is not a priority in the care plan for a client with hemophilia.
Choice C rationale:
Hemarthrosis is a critical complication that should be prioritized in the care plan for a client with hemophilia.
Hemarthrosis is the bleeding into joint spaces, which can lead to severe pain, swelling, and reduced range of motion in the affected joint.
It is a common and serious complication in individuals with hemophilia because bleeding into joints can cause long-term damage and disability.
Therefore, the nurse should prioritize assessing and managing hemarthrosis in the client's care plan to prevent further complications.
What intervention should the nurse include in the teaching?
Explanation
Choice A rationale:
Administering anticoagulants to promote clot formation is not appropriate for the treatment of hemophilia.
Anticoagulants are medications that thin the blood and prevent the formation of blood clots.
However, in individuals with hemophilia, the issue is not the formation of excessive clots but rather the inability to form effective clots due to a deficiency in clotting factors.
Therefore, anticoagulants would worsen the bleeding disorder and are not a suitable intervention.
Choice B rationale:
Encouraging regular physical activity to prevent bleeding episodes is a reasonable recommendation for individuals with hemophilia.
Regular, low-impact physical activity can help strengthen muscles and joints, which may reduce the risk of bleeding episodes and joint damage.
However, this alone is not a treatment for hemophilia but rather a preventive measure.
Choice C rationale:
Administering factor replacement therapy is the primary treatment for hemophilia.
Hemophilia is characterized by a deficiency in specific clotting factors (Factor VIII for Hemophilia A and Factor IX for Hemophilia B)
Replacement therapy involves infusing the missing clotting factor to achieve normal or near-normal levels, allowing the blood to clot properly.
This intervention is crucial in managing and preventing bleeding episodes in individuals with hemophilia.
Choice D rationale:
Administering iron supplements to improve hemoglobin levels is not a direct treatment for hemophilia.
Hemophilia is a clotting disorder, and iron supplements are typically used to treat conditions related to iron deficiency anemia.
While individuals with hemophilia may experience anemia as a result of chronic bleeding, the primary treatment for hemophilia involves addressing the clotting factor deficiency through factor replacement therapy.
.
The client reports pain, swelling, and reduced range of motion in their joints.
Which of the following statements by the nurse is appropriate?
Explanation
Choice A rationale:
"It's just a minor issue, and the pain will go away on its own." This statement is not appropriate because joint pain, swelling, and reduced range of motion in a client with hemophilia, known as hemarthrosis, can lead to long-term joint damage and disability if not properly managed.
Downplaying the issue is not in the best interest of the client and may lead to inadequate care.
Choice B rationale:
"Let's apply ice to the affected joint to reduce the swelling." While applying ice to an inflamed joint can help reduce swelling in some cases, it may not be the best immediate approach for a client with hemophilia.
Ice application should be done with caution, as it can potentially worsen bleeding in individuals with hemophilia.
The primary focus should be on assessing the severity of the bleeding, providing appropriate pain management, and consulting with a healthcare provider.
Choice C rationale:
"I'll assess your joint and provide pain management as needed." This is the most appropriate response.
The nurse should assess the client's joint for signs of hemarthrosis, such as swelling, warmth, and reduced range of motion.
Prompt assessment allows for early intervention to manage the bleeding and alleviate pain.
Providing pain management as needed, which may include analgesic medications, is essential to improve the client's comfort and prevent further complications.
Choice D rationale:
"You should perform strenuous exercises to improve joint mobility." Encouraging strenuous exercises in a client with hemophilia who is already experiencing joint pain and swelling is not advisable.
Strenuous exercise can exacerbate bleeding and joint damage.
Instead, the focus should be on gentle range-of-motion exercises and physical therapy, guided by a healthcare provider, to improve joint mobility without increasing the risk of bleeding.
Which statement by the nurse is correct?
Explanation
Choice A rationale:
"It's essential to limit your fluid intake to prevent further bleeding." Rationale: This statement is incorrect.
Limiting fluid intake will not prevent bleeding in a client with hemophilia.
In fact, maintaining adequate hydration is important to prevent complications and maintain overall health.
Choice B rationale:
"Let's administer aspirin to help with the pain and swelling." Rationale: This statement is also incorrect.
Aspirin is not recommended for individuals with hemophilia as it can further increase the risk of bleeding due to its antiplatelet effects.
Administering aspirin would be contraindicated in this case.
Choice C rationale:
"I'll monitor your condition closely and provide appropriate treatments." Rationale: This is the correct statement.
For a client with hemophilia experiencing bleeding into muscles, soft tissues, and the gastrointestinal tract, close monitoring and appropriate treatments are essential.
This may include administering clotting factor concentrates, pain management, and supportive care.
Choice D rationale:
"This bleeding is normal and should resolve on its own." Rationale: This statement is incorrect and potentially dangerous.
Bleeding in a client with hemophilia is not normal and should not be left untreated.
Without intervention, it can lead to severe complications and even life-threatening situations.
A nurse is educating a group of clients with hemophilia about diagnostic evaluation.
Which tests are typically used to diagnose hemophilia?
Explanation
Choice A rationale:
Genetic testing for the F8 or F9 gene mutations.
Rationale: Genetic testing for mutations in the F8 (Factor VIII) or F9 (Factor IX) genes is a critical diagnostic evaluation for hemophilia.
Hemophilia A is caused by mutations in the F8 gene, while hemophilia B is caused by mutations in the F9 gene.
Choice B rationale:
Prothrombin time (PT)
Rationale: PT is not typically used to diagnose hemophilia.
It primarily evaluates the extrinsic and common coagulation pathways, which are not directly related to hemophilia, which is a disorder of the intrinsic coagulation pathway.
Choice C rationale:
Partial thromboplastin time (PTT)
Rationale: PTT is one of the key tests used to diagnose hemophilia.
It assesses the intrinsic coagulation pathway, and prolonged PTT results may indicate a bleeding disorder, including hemophilia.
Choice D rationale:
Platelet count.
Rationale: Platelet count is not a specific test for diagnosing hemophilia.
Hemophilia is a deficiency in clotting factors, not a platelet disorder.
Platelet counts are typically normal in individuals with hemophilia.
Choice E rationale:
Fibrinogen levels.
Rationale: Fibrinogen levels are not typically used to diagnose hemophilia.
Hemophilia is characterized by deficiencies in specific clotting factors (Factor VIII or Factor IX), and fibrinogen levels are not directly related to these factors.
What information should the nurse include in the history assessment?
Explanation
Choice A rationale:
Family history of bleeding disorders.
Rationale: In the assessment of a client suspected of having hemophilia, it is essential to inquire about a family history of bleeding disorders because hemophilia is a genetic disorder, and a positive family history can be a strong indicator.
Choice B rationale:
Recent traumatic injuries.
Rationale: Inquiring about recent traumatic injuries is important because individuals with hemophilia are at increased risk of bleeding following injuries.
Knowing about recent trauma helps assess the risk of bleeding episodes.
Choice C rationale:
Medications affecting coagulation.
Rationale: It is crucial to inquire about medications that can affect coagulation, such as anticoagulants or antiplatelet agents, as these medications can increase the risk of bleeding in individuals with hemophilia.
Choice D rationale:
Allergies to latex products.
Rationale: While allergies to latex products should be assessed for safety reasons, it is not directly related to the diagnosis of hemophilia.
This information is important for overall patient safety but is not a specific factor in diagnosing hemophilia.
Which aspect of the assessment should the nurse prioritize to determine the type and severity of hemophilia?
Explanation
Choice A rationale:
"Can you describe the triggers for your bleeding episodes?”
This is the correct choice.
Understanding the triggers for bleeding episodes can help determine the type and severity of hemophilia.
For example, frequent spontaneous bleeding without apparent triggers may suggest severe hemophilia, while bleeding triggered by trauma or surgery may indicate a milder form.
Choice B rationale:
"What is the frequency of your joint pain?”
This choice is relevant to assessing the impact of hemophilia on the patient's quality of life but does not directly help determine the type and severity of hemophilia.
Choice C rationale:
"Do you have a family history of hemophilia?”
While family history is important in assessing the risk of hemophilia, it alone does not provide information about the type and severity of the patient's condition.
Choice D rationale:
"Have you been prescribed antifibrinolytic agents?”
This question pertains to treatment rather than the assessment of the type and severity of hemophilia.
It is important to know the treatment history but does not provide direct insight into the condition's severity.
What nursing intervention should the nurse prioritize for managing the client's pain?
Explanation
"Apply pressure, ice, and compression to the affected joint."
Choice A rationale:
"Administer acetaminophen as prescribed." While pain management is essential for clients with hemophilia, acetaminophen is not the first-line choice because it does not have anti-inflammatory properties.
Additionally, in hemophilia, there is a risk of liver damage from excessive acetaminophen use.
Choice B rationale:
"Apply pressure, ice, and compression to the affected joint." This is the correct choice.
Applying ice and compression to the affected joint can help reduce pain and inflammation in clients with hemophilia.
It is a safe and effective nursing intervention.
Choice C rationale:
"Refer the client to genetic counseling services." Genetic counseling is important in hemophilia for family planning and risk assessment.
However, it is not the priority nursing intervention for managing acute joint pain.
Choice D rationale:
"Encourage the client to perform vigorous physical exercises." Encouraging vigorous physical exercises is not advisable for clients with hemophilia, especially when they are experiencing joint pain.
It can increase the risk of bleeding and further joint damage.
A nurse is providing education to a patient with hemophilia about self-care measures.
Which recommendations should the nurse include? (Select all that apply.)
Explanation
Choice A rationale:
The nurse should recommend avoiding invasive procedures and injections for a patient with hemophilia.
Hemophilia is a bleeding disorder characterized by a deficiency in clotting factors, and any invasive procedures or injections can lead to bleeding episodes.
This recommendation is essential to prevent unnecessary bleeding and complications.
Choice B rationale:
The use of nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief is not a suitable recommendation for a patient with hemophilia.
NSAIDs can increase the risk of bleeding due to their antiplatelet effects.
It is crucial to avoid medications that can worsen bleeding in individuals with hemophilia.
Choice C rationale:
Engaging in gentle exercise to maintain joint function is a valuable recommendation for patients with hemophilia.
Hemophilia often leads to joint problems due to repeated bleeding episodes, and gentle exercise can help maintain joint mobility and prevent contractures.
It is essential to recommend exercise within the patient's tolerance to promote joint health.
Choice D rationale:
Monitoring for signs of anemia and thrombosis is important for patients with hemophilia.
Anemia can occur if there is excessive bleeding, leading to a decrease in red blood cell count.
Additionally, patients with hemophilia are at risk of developing thrombosis due to treatment with clotting factor concentrates.
Therefore, regular monitoring for these complications is necessary to ensure timely intervention if needed.
Choice E rationale:
Applying heat to bleeding joints to alleviate pain is not a recommended practice for patients with hemophilia.
Heat can increase blood flow to the affected area, potentially exacerbating bleeding.
Cold therapy, such as ice packs, is often recommended to reduce inflammation and pain while minimizing the risk of bleeding.
Explanation
Choice A rationale:
Desmopressin acetate (DDAVP) is a medication used to stimulate the release of factor VIII and von Willebrand factor from endothelial cells.
It is particularly effective in patients with mild to moderate hemophilia A who have a functional von Willebrand factor.
DDAVP works by promoting the release of stored clotting factors from the endothelium, temporarily increasing their levels in the bloodstream.
This medication is administered intranasally, subcutaneously, intravenously, or orally, making it a versatile option for treatment in different clinical settings.
Choice B rationale:
Factor VIII concentrates are used for the replacement of factor VIII in patients with hemophilia A but do not stimulate the release of factor VIII and von Willebrand factor from endothelial cells.
Factor VIII concentrates are typically administered intravenously to replace the deficient clotting factor.
Choice C rationale:
Tranexamic acid is an antifibrinolytic agent used to prevent the breakdown of fibrin clots.
While it can help in managing bleeding episodes in patients with hemophilia, it does not stimulate the release of factor VIII or von Willebrand factor from endothelial cells.
Choice D rationale:
Gene therapy is an emerging treatment approach for hemophilia, but it does not stimulate the release of factor VIII and von Willebrand factor from endothelial cells.
Gene therapy aims to provide a long-term solution by introducing functional clotting factor genes into the patient's body.
Which drug, used as adjunctive therapy to inhibit the breakdown of fibrin clots, should the nurse consider?
