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. This is because ceftriaxone belongs to the same class of antibiotics as penicillin (cephalosporins) and can cross-react in individuals with a penicillin allergy, potentially leading to anaphylaxis.
Therefore, it is contraindicated in this client.
Vancomycin (
A), clarithromycin (
B), and metronidazole (
C) are not contraindicated in individuals with a penicillin allergy as they do not belong to the same antibiotic class.
In summary, the other choices are incorrect because they do not share the same cross-reactivity concerns with penicillin as ceftriaxone does.
