← Human Body & HealthIf a patient undergoes high-dose radiation therapy leading to bone marrow damage and subsequent aplastic anemia, which consequence directly impacts erythropoiesis?
A)Increased iron absorption in enterocytes
B)Decreased erythrocyte progenitor cell production✓
C)Elevated reticulocyte maturation into erythrocytes
D)Enhanced erythropoietin receptor sensitivity
💡 Explanation
Aplastic anemia, resulting from radiation-induced bone marrow damage, directly impairs the production of erythrocyte progenitor cells because it destroys the hematopoietic stem cells responsible for erythropoiesis; therefore, fewer red blood cells are produced, rather than affecting iron absorption or erythropoietin sensitivity.
