A nurse is preparing to transfuse one unit of packed RBC to a client who experienced a mild allergic reaction during a previous transfusion. The nurse should administer diphenhydramine prior to the transfusion for which of the following allergic responses?
Correct answer
B
Rationale
The correct answer is B: Urticaria. Diphenhydramine is an antihistamine that helps manage allergic reactions like urticaria (hives). Urticaria is a common manifestation of mild allergic reactions during transfusions. Administering diphenhydramine before the transfusion can help prevent or alleviate this allergic response.
Incorrect Answers:
A: Fluid overload - Diphenhydramine is not used to treat fluid overload. It is managed by adjusting IV fluids and diuretics.
C: Hemolysis - Diphenhydramine does not address hemolysis, which is the breakdown of RBCs.
D: Fever - Diphenhydramine is not indicated for treating fever, as it is not an antipyretic. Fever during transfusion may indicate other issues such as infection.
