Question 1 of 5
A nurse is caring for a client who has cellulitis and is to begin antibiotic therapy. The client has a history of anaphylactic reaction to penicillin. Which of the following medications is contraindicated for this client?
Correct Answer: D
Rationale: The correct answer is D: Cephalexin. Cephalexin is a first-generation cephalosporin antibiotic, which shares a similar beta-lactam ring structure with penicillin. Due to the client's history of anaphylactic reaction to penicillin, there is a high risk of cross-reactivity and potential severe allergic reaction if cephalexin is administered.
Therefore, it is contraindicated for this client.
Choice A: Fluconazole is an antifungal medication and does not have cross-reactivity with penicillin.
Choice B: Tetracycline is a broad-spectrum antibiotic that is not related to penicillin.
Choice C: Acyclovir is an antiviral drug and is not contraindicated in a client with a penicillin allergy.
