← Human Body & HealthIf a patient with anemia receives a blood transfusion, why does a temporary decrease in erythropoietin (EPO) production reduce reticulocyte count?
A)Iron overload suppresses marrow function
B)Antibodies destroy newly formed cells
C)EPO directly inhibits reticulocyte release
D)Increased oxygen reduces EPO stimulation✓
💡 Explanation
A blood transfusion increases the oxygen-carrying capacity of the blood, which reduces the need for EPO production because tissue hypoxia diminishes. The decreased EPO results in lower stimulation of the bone marrow, therefore, reticulocyte production decreases rather than continuing at the previous rate.
