Anemia Treatment and Hematopoiesis Quiz

Which of the following is the most common oral iron supplement used to treat iron deficiency anemia?

• Ferrous sulfate

• Iron dextran

• Ferric gluconate

• Cyanocobalamin

What is the primary function of erythropoietin in the body?

• Stimulate white blood cell production

• Stimulate red blood cell production

• Increase platelet count

• Enhance iron absorption

A deficiency of which vitamin leads to pernicious anemia?

• Vitamin C

• Vitamin B12

• Vitamin D

• Folic acid

Which of the following is essential for DNA synthesis and is especially important during periods of rapid cell division, such as in pregnancy?

• Iron

• Folic acid

• Vitamin K

• Calcium

Which laboratory value is most likely to increase after successful iron supplementation in a patient with iron deficiency anemia?

• White blood cell count

• Hemoglobin concentration

• Platelet count

• Serum calcium

A patient with chronic kidney disease is prescribed an erythropoiesis-stimulating agent (ESA). What is the most likely reason for this prescription?

• To treat leukopenia

• To stimulate red blood cell production due to decreased endogenous erythropoietin

• To increase platelet production

• To enhance iron absorption

A patient presents with macrocytic anemia and neurological symptoms. Which deficiency is most likely responsible?

• Iron deficiency

• Folic acid deficiency

• Vitamin B12 deficiency

• Vitamin C deficiency

A patient is found to have megaloblastic anemia. Laboratory tests reveal normal vitamin B12 levels but low folate levels. Which drug would be most appropriate to prescribe?

• Ferrous sulfate

• Epoetin alfa

• Folic acid

• Iron dextran

A 65-year-old patient with a history of gastric surgery develops anemia. Laboratory findings show low hemoglobin, high mean corpuscular volume (MCV), and low serum vitamin B12. Explain the likely mechanism leading to this anemia and suggest an appropriate treatment.

• Decreased iron absorption; treat with oral iron

• Decreased intrinsic factor production; treat with intramuscular vitamin B12

• Increased folic acid requirement; treat with oral folic acid

• Bone marrow suppression; treat with erythropoietin

A patient with aplastic anemia is being evaluated for bone marrow transplantation. Discuss the role of bone marrow in hematopoiesis and explain why transplantation may be necessary in this condition.

• Bone marrow produces only red blood cells; transplantation is needed to increase oxygen delivery.

• Bone marrow produces all blood cell types; transplantation restores hematopoiesis when marrow fails.

• Bone marrow stores iron; transplantation is needed to correct iron deficiency.

• Bone marrow produces antibodies; transplantation is needed to boost immunity.
