A patient with anemia undergoes a bone marrow biopsy, which shows erythroid hyperplasia. What does this finding most likely indicate?

A A decrease in erythropoietin production
B An increase in the destruction of red blood cells ✓
C A defect in the production of red blood cells
D An inadequate response to erythropoietin

Explanation

Erythroid hyperplasia in the bone marrow indicates that the marrow is responding appropriately to anemia by increasing red blood cell production. This is often seen in conditions where there is increased destruction of red blood cells, such as hemolytic anemias.
