What effect does epoetin alfa have on red blood cell production?

Epoetin alfa is a synthetic form of erythropoietin, which is a hormone produced by the kidneys that stimulates the production of red blood cells (RBCs) in the bone marrow. When administered, epoetin alfa mimics the action of natural erythropoietin in the body, promoting erythropoiesis, or the formation of red blood cells.

This medication is commonly used in patients with anemia, particularly those who have chronic kidney disease or are undergoing chemotherapy, where their bodies may not produce enough erythropoietin naturally. By enhancing the production of red blood cells, epoetin alfa helps to increase hemoglobin levels and improve oxygen delivery to tissues, which can alleviate the symptoms of fatigue and weakness associated with anemia.

The other response options do not accurately represent the function of epoetin alfa in relation to red blood cell production. For instance, it does not decrease RBC production, stabilize existing RBCs, or eliminate red blood cells. Instead, the primary role of this medication is to stimulate the production of new red blood cells, making the correct choice clear.
