If a patient presents with microcytic anemia due to chronic kidney disease, what compensatory change would be least effective in improving erythropoiesis?

💡 Explanation

Erythropoietin (EPO) stimulates red blood cell production; in kidney disease, EPO production is impaired. Administering recombinant EPO directly addresses the deficiency, therefore this is more effective, rather than simply supplementing iron or folate when the issue is EPO deficiency. The others provide substrates but not stimulation.
