Epoetin used in chronic kidney disease stimulates red blood cell production. Which option best describes its role?

• A. Increases white blood cell production
• B. Inhibits platelet function
• C. Increases red blood cell destruction
• D. Stimulates red blood cell production

Answer: (D)

Erythropoietin’s role is to signal the bone marrow to produce red blood cells. In chronic kidney disease, the kidneys don’t make enough erythropoietin, leading to anemia. Giving epoetin provides that signal again, boosting red blood cell production and improving oxygen delivery. It does not affect white blood cells, platelets, or red cell destruction, which is why the option describing stimulation of red blood cell production is the correct choice.
