Question 1 of 5
A client diagnosed with strep throat requires antibiotics for treatment. With an allergy to penicillin, the nurse understands which medication should be avoided due to cross-sensitivity with penicillin medications?
Correct Answer: D
Rationale: The correct answer is D: Cephalosporins. Cephalosporins share a similar beta-lactam ring structure with penicillins, leading to potential cross-reactivity in patients with penicillin allergies. Macrolides (
A), antiretrovirals (
B), and antimalarials (
C) do not have this structural similarity, so they are safe alternatives for patients allergic to penicillin. In summary, choosing cephalosporins for a patient with a penicillin allergy can lead to an allergic reaction due to cross-sensitivity, making it an inappropriate choice in this scenario.
