The medication used to treat anemia is:

• A. Vitamin C
• B. Epogen
• C. Iron tablets
• D. Folic acid

Answer: (B)

Anemia in patients with kidney disease is usually treated with a medication that directly boosts red blood cell production. Epogen (epoetin alfa) is an erythropoiesis-stimulating agent that mimics the body's own erythropoietin. It signals the bone marrow to produce more red blood cells, which raises hemoglobin and helps reduce symptoms of anemia.

Iron tablets treat iron deficiency anemia by replenishing iron stores, which supports red blood cell production, but they don’t address the lack of erythropoietin itself. Folic acid treats folate deficiency anemia, and vitamin C is not used as a primary treatment for anemia (though it can aid iron absorption in some contexts). In the typical dialysis-associated anemia, Epogen is the medication that directly corrects the underlying issue by increasing RBC production, making it the best choice.
