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: C
Rationale: The correct answer is C: Cephalosporins. Cephalosporins should be avoided in a client with a penicillin allergy due to cross-sensitivity. Both penicillins and cephalosporins share a similar beta-lactam ring structure, which can lead to allergic reactions in individuals with a penicillin allergy. Macrolides (
A), sulfonamides (
B), and tetracyclines (
D) do not have cross-sensitivity with penicillin and are safe alternatives for a client with a penicillin allergy.
