Your patient is allergic to penicillin. He may also have a cross-allergy to which class of antibiotics?
Correct answer
D
Rationale
The correct answer is D: Cephalosporins. Cephalosporins are structurally similar to penicillin, which can lead to cross-allergies in patients allergic to penicillin. Aminoglycosides (A), Sulfonamides (B), and Macrolides (C) are different classes of antibiotics and do not typically cross-react with penicillin allergies. Therefore, they are incorrect choices for this scenario.
