A patient tells the nurse that he is allergic to penicillin. What would be the nurse’s best response to this information?

Choice A reason: Asking about other drug allergies is relevant but secondary to understanding the penicillin allergy’s nature. Without clarifying the reaction’s severity (e.g., anaphylaxis vs. rash), the nurse cannot fully assess the risk, making this a less immediate response. Choice B reason: Asking about the frequency of penicillin use does not address the nature or severity of the allergic reaction. This information is irrelevant to managing the allergy and ensuring patient safety, making it an inappropriate initial response. Choice C reason: Asking the patient to describe their reaction to penicillin clarifies the type and severity of the allergy (e.g., rash, anaphylaxis). This informs safe medication administration and prevents adverse reactions, making it the most critical and appropriate response. Choice D reason: Documenting the allergy is necessary but premature without understanding the reaction’s specifics. Assuming the allergy without verification could lead to incomplete charting or mismanagement, making this a less priority response compared to gathering details.
