Question 1 of 5
A patient is allergic to penicillin. Which class of antibiotics might they also have a cross-allergy to?
Correct Answer: Cephalosporins share a similar structure with penicillin, risking cross-allergy. Sulfonamides, macrolides, and aminoglycosides lack this relation.
Rationale: The correct answer is A: Cephalosporins. Cephalosporins have a beta-lactam ring structure similar to penicillin, leading to potential cross-allergy. Sulfonamides, macrolides, and aminoglycosides have different chemical structures, reducing the likelihood of cross-allergy.
Therefore, individuals allergic to penicillin may have a cross-allergy to cephalosporins due to structural similarity, making it the correct choice.
