The nurse recognizes that which diagnostic test is used to detect the most common cause of chronic iron deficiency anemia?

Stool for occult blood

Vitamin B12 level

Schilling's test

Bone marrow aspiration study

Answer and Explanation

The Correct Answer is A

Choice A reason: This is the correct answer. Stool for occult blood is a diagnostic test that detects the presence of hidden blood in the feces. This can indicate bleeding in the gastrointestinal tract, which is the most common cause of chronic iron deficiency anemia. Iron deficiency anemia is a condition where the body does not have enough iron to produce hemoglobin, the protein that carries oxygen in the red blood cells.

Choice B reason: Vitamin B12 level is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Vitamin B12 level is a blood test that measures the amount of vitamin B12 in the body. Vitamin B12 is a nutrient that is essential for the production of red blood cells and the maintenance of the nervous system. Vitamin B12 deficiency can cause pernicious anemia, a type of megaloblastic anemia where the red blood cells are large and immature.

Choice C reason: Schilling's test is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Schilling's test is a urine test that evaluates the absorption of vitamin B12 in the body. It involves giving the client an oral dose of radioactive vitamin B12 and an intramuscular injection of non-radioactive vitamin B12. The urine is then collected and measured for the amount of radioactive vitamin B12. Schilling's test can help diagnose pernicious anemia and other causes of vitamin B12 malabsorption.

Choice D reason: Bone marrow aspiration study is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Bone marrow aspiration study is a procedure that involves taking a sample of bone marrow from the hip or sternum and examining it under a microscope. Bone marrow is the soft tissue inside the bones that produces blood cells. Bone marrow aspiration study can help diagnose various blood disorders, such as leukemia, lymphoma, and aplastic anemia.

Correct Answer is C

Explanation

Choice A reason: Limiting the intake of citrus juices is not related to the teaching about hydrochlorothiazide. Citrus juices are rich in vitamin C, which has no significant interaction with hydrochlorothiazide. The client does not need to avoid or limit citrus juices unless they have other medical conditions that require dietary restrictions.

Choice B reason: Eating bananas daily to lower the potassium level is a wrong statement. Bananas are high in potassium, which is a mineral that hydrochlorothiazide can deplete from the body. The client may need to increase their potassium intake or take a potassium supplement to prevent hypokalemia, a condition of low potassium level that can cause muscle weakness, cramps, and arrhythmias.

Choice C reason: Taking the pill each day in the morning is the correct statement. Hydrochlorothiazide is a diuretic that increases the urine output and reduces the blood volume and pressure. The client should take the pill in the morning to avoid nocturia, which is frequent urination at night that can disrupt the sleep quality and increase the risk of falls.

Choice D reason: Taking the pill each day after dinner is not the best statement. Hydrochlorothiazide can cause diuresis, which is increased urine production and excretion. Taking the pill after dinner can lead to nocturia, which is frequent urination at night that can interfere with the sleep cycle and cause fatigue and irritability. The client should take the pill in the morning to prevent nocturia and its complications.
