A nurse is assessing a client following the administration of an initial dose of captopril. Which of the following findings indicates an anaphylactic response?
Laryngeal edema
Fever
Hypertension
Arrhythmia
The Correct Answer is A
Choice A reason: Laryngeal edema is a classic sign of anaphylaxis, a severe and potentially life-threatening allergic reaction. It can lead to difficulty breathing and requires immediate medical attention. Anaphylaxis can occur with any medication, including captopril, especially on initial exposure.
Choice B reason: Fever is not typically a sign of anaphylaxis. While it can be a symptom of various infections or inflammatory processes, it is not indicative of an immediate hypersensitivity reaction.
Choice C reason: Hypertension, or high blood pressure, is not a sign of anaphylaxis. In fact, during an anaphylactic reaction, blood pressure often drops significantly, a condition known as anaphylactic shock.
Choice D reason: Arrhythmia, or an irregular heartbeat, can be associated with various cardiac conditions but is not a specific indicator of anaphylaxis. While severe allergic reactions can affect heart rate, they are more likely to cause hypotension than arrhythmia.

Correct Answer is B
Explanation
Choice A reason : Desmopressin is a medication used to treat conditions like diabetes insipidus and certain cases of hemophilia, not allergic reactions such as hives and urticaria.
Choice B reason: Diphenhydramine is an antihistamine that is commonly used to treat allergic reactions, including hives and urticaria. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.
Choice C reason: Spironolactone is a diuretic and is not used to treat allergic reactions. It is typically prescribed for conditions like heart failure, hypertension, and certain hormonal disorders.
Choice D reason: Metoclopramide is a medication used to treat nausea and gastroparesis, not allergic reactions.
