Question 1 of 5
A nurse is preparing to administer diphenhydramine to a client who is to receive a blood transfusion. The nurse should explain that the purpose of diphenhydramine is to prevent which of the following manifestations of a transfusion reaction?
Correct Answer: D
Rationale: The correct answer is D: Urticaria. Diphenhydramine is an antihistamine that helps to prevent and treat allergic reactions, such as urticaria (hives), which can occur during a blood transfusion. Histamine release can lead to symptoms like itching, redness, and swelling of the skin (urticaria). Diphenhydramine works by blocking the effects of histamine, thereby reducing these symptoms. Low-back pain (
A) is not typically associated with transfusion reactions. Fever (
B) may indicate a febrile reaction to a transfusion but is not the main reason diphenhydramine is given. Dyspnea (
C) is more indicative of a severe allergic reaction or transfusion-related acute lung injury, which would require immediate medical intervention.
