Pharmacy Technician Certification Exam Practice Questions Practice Question
When filling a prescription for a patient with a penicillin allergy,the pharmacy computer should also identify a potential allergy to which class of drugs?
Correct Answer: A
Rationale: Patients with a penicillin allergy may also have cross-reactivity with cephalosporins due to their similar beta-lactam structure. This similarity can trigger allergic reactions in sensitive individuals.
Macrolides (B) and aminoglycosides (C) are structurally different from penicillins, making them less likely to cause cross-reactivity. Glycopeptides (D) also do not share structural similarities with penicillin, so they are not typically associated with increased allergy risk. Therefore, while cephalosporins warrant caution, the other options do not present the same potential allergy concern.
