Question 1 of 5
A nurse is reviewing the medical history of a client prior to medication administration and notes a history of an anaphylactic reaction to penicillin. The nurse should identify that which of the following medications is contraindicated for this client?
Correct Answer: D
Rationale: The correct answer is D: Ceftriaxone. Penicillin and ceftriaxone belong to the same antibiotic class (beta-lactams), which can cross-react in clients allergic to penicillin. This client's history of an anaphylactic reaction to penicillin indicates a high risk of an allergic reaction to ceftriaxone. Metronidazole (
A), clarithromycin (
B), and vancomycin (
C) are not contraindicated in clients with a penicillin allergy as they do not share a similar chemical structure or mechanism of action.
