A patient is being treated in the ICU after a medical error resulted in an acute hemolytic transfusion reaction. What was the etiology of this patient's adverse reaction?
A) Antibodies to donor leukocytes remained in the blood.
B) The donor blood was incompatible with that of the patient.
C) The patient had a sensitivity reaction to a plasma protein in the blood.
D) The blood was infused too quickly and overwhelmed the patient's circulatory system.
Ans: B
Feedback:
An acute hemolytic reaction occurs when the donor blood is incompatible with that of the recipient. In the case of a febrile nonhemolytic reaction, antibodies to donor leukocytes remain in the unit of blood or blood component. An allergic reaction is a sensitivity reaction to a plasma protein within the blood component. Hypervolemia does not cause an acute hemolytic reaction.
