Which medication in the regimen is used to treat anemia by stimulating red blood cell production?

• A. Calcium acetate
• B. Epoetin alfa
• C. Furosemide
• D. Potassium chloride

Answer: (B)

Stimulation of red blood cell production is achieved by medications that mimic the body’s own erythropoietin, signaling the bone marrow to produce more RBCs. Epoetin alfa is such a drug; it acts like erythropoietin and prompts erythroid progenitor cells in the bone marrow to increase RBC formation, helping to treat anemia. This is especially useful in conditions like chronic kidney disease or chemotherapy-induced anemia, where natural erythropoietin is deficient. Calcium acetate serves as a phosphate binder and does not drive red cell production; furosemide is a diuretic, and potassium chloride is used to replace potassium. Because epoetin alfa directly stimulates RBC synthesis, it is the appropriate choice for treating anemia by boosting red blood cell production.
