Adequate ______ are essential for Epogen to be effective.

Adequate ______ are essential for Epogen to be effective.

• A. Platelets
• B. Hemoglobin
• C. Iron stores
• D. Calcium

Answer: (C)

Iron availability governs how well Epogen works because erythropoiesis relies on iron to build hemoglobin in new red blood cells. Epogen prompts the bone marrow to make more RBCs, but without enough iron, those cells cannot form functional hemoglobin, so hemoglobin levels don’t rise and anemia persists. That’s why checking and replenishing iron stores is essential when using Epogen. Platelets or calcium aren’t substrates for red cell production, and simply having a higher baseline hemoglobin won’t guarantee a better response without adequate iron.
