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 have a similar beta-lactam ring structure to penicillins, leading to potential cross-sensitivity in patients with penicillin allergy. Macrolides (
A), Sulfonamides (
B), and Tetracyclines (
D) are different classes of antibiotics and do not typically cross-react with penicillins.
Therefore, they are safe alternatives for patients allergic to penicillin.
