← Human Body & HealthFollowing a radiation accident that suppresses bone marrow function, which effect becomes evident in peripheral blood, causing pancytopenia, and increasing the risk of severe infection?
A)Elevated erythropoietin levels
B)Reduced neutrophil count✓
C)Increased reticulocyte percentage
D)Shift toward microcytic anemia
💡 Explanation
Aplastic anemia results from bone marrow damage, leading to decreased production of all blood cells, including neutrophils; therefore, a reduced neutrophil count increases infection risk, because of the impaired innate immune response rather than the other effects such as reticulocytosis, or increased erythropoietin.
