A person with anemia is prescribed erythropoietin subcutaneously. The nurse knows that erythropoietin:
Stimulates bone marrow production of red blood cells.
Is given to all people with anemia.
Is given for iron deficiency anemia.
Stimulates bone marrow production of white blood cells.
The Correct Answer is A
This helps increase the oxygen-carrying capacity of the blood and corrects anemia.
Choice B is wrong because erythropoietin is not given to all people with anemia. It is only used for certain types of anemia, such as those caused by chronic kidney disease or chemotherapy.
Choice C is wrong because erythropoietin is not given for iron deficiency anemia. Iron deficiency anemia is treated with iron supplements and dietary changes.
Choice D is wrong because erythropoietin does not stimulate bone marrow production of white blood cells. White blood cells are involved in immune responses and are produced by different growth factors.

Correct Answer is A
Explanation
Hypothermia is a condition where the body temperature drops below 35°C (95°F) and affects the normal functioning of the body. Elderly people are more at risk for hypothermia because they have a lower muscle mass, a decreased
shiver reflex, and lower immunity. They also tend to have a lower body temperature and may not develop fevers when they contract a viral or bacterial illness.
Choice B. Normothermia is wrong because it means having a normal body temperature, which is around 37°C (98.6°F).
Choice C. Hyperthermia is wrong because it means having a high body temperature, which is above 37.5°C (99.5°F).
Hyperthermia can be caused by heat exposure, infection, inflammation, or certain medications.
Choice D. Malignant hyperthermia is wrong because it is a rare genetic disorder that causes a severe reaction to certain anesthetics or muscle relaxants.
It is not related to thermoregulation in elderly people.
Question 5.
Correct Answer is C
Explanation
This type of anemia is caused by the reduced absorption of vitamin B12 in the small intestine after gastric bypass surgery. Vitamin B12 is needed for the production of healthy red blood cells and nerve function. The symptoms of vitamin B12 deficiency anemia include sore tongue, tingling in the fingers, and balance problems.
Choice A is wrong because folic acid deficiency anemia is caused by the lack of folic acid in the diet or increased demand for folic acid, such as during pregnancy.
Folic acid is also needed for red blood cell production, but it does not cause nerve symptoms.
Choice B is wrong because aplastic anemia is caused by the failure of the bone marrow to produce enough blood cells.
It is not related to gastric bypass surgery or nutrient deficiency. It can be caused by infections, drugs, radiation, or autoimmune diseases.
Choice D is wrong because acquired anemia is a general term for any type of anemia that is not inherited or present at birth.
It can have many causes, such as blood loss, infection, inflammation, or chronic disease.
It does not specify the type of anemia or the underlying mechanism. Normal ranges for hemoglobin are 13.5 to 17.5 g/dL for men and 12 to 15.5 g/dL for women. Normal ranges for vitamin B12 are 200 to 900 pg/mL.
