The nurse is caring for a patient receiving treatment for a hemolytic reaction from a mismatched blood transfusion. The nurse understands that this the incompatible blood is causing what?
Malformed RBCs
A deficiency in vitamin B12
An abundance of immature RBCS
Destruction of RBCs
The Correct Answer is D
A. Malformed RBCs: Malformed RBCs are not caused by a transfusion reaction; they are generally a result of bone marrow abnormalities or genetic conditions.
B. A deficiency in vitamin B12: Vitamin B12 deficiency causes megaloblastic anemia, not hemolysis. It is unrelated to transfusion reactions.
C. An abundance of immature RBCs: Immature RBCs, or reticulocytes, can increase as a compensatory response to anemia but are not a direct result of a transfusion reaction. The primary issue is RBC destruction.
D. Destruction of RBCs: A hemolytic reaction occurs when the immune system attacks incompatible red blood cells, leading to their destruction.

Correct Answer is A
Explanation
A. Stop the transfusion: Stopping the transfusion is the priority action to prevent further exposure to the antigen causing the reaction.
B. Administer diphenhydramine: Administering diphenhydramine is an appropriate intervention for allergic reactions, but stopping the transfusion should be done first to halt the reaction source.
C. Obtain vital signs. Obtaining vital signs is important but should follow stopping the transfusion to address the immediate risk of reaction.
D. Notify the registered nurse: Notifying the registered nurse is necessary but comes after stopping the transfusion to immediately mitigate the reaction.
Correct Answer is D
Explanation
A. 2 hr: While some patients may tolerate faster infusion rates, the maximum safe time is 4 hours, and there is no requirement to complete it in 2 hours.
B. 8 hr: Blood cannot be left out for 8 hours due to the increased risk of bacterial growth and contamination.
C. 6 hr: Infusing blood over 6 hours exceeds the safe time limit and poses a risk of bacterial contamination.
D. 4 hr: To reduce the risk of bacterial contamination, a unit of packed RBCs must be transfused within 4 hours of starting the infusion. This time frame ensures that the blood remains safe for the patient while minimizing exposure to room temperature.
