Question

a nurse is caring for a client who has streptococcal pharyngitis and an allergy to penicillin. the nurse should recognize that which of the following medications can be safely administered to this client?
nafcillin
azithromycin
cephalexin
amoxicillin/clavulanic acid

Explanation:

To solve this, we analyze each medication:

• Nafcillin: A penicillin - type antibiotic. Since the client is allergic to penicillin, it's not safe.
• Azithromycin: A macrolide antibiotic. It's not related to penicillin, so it can be safely used for streptococcal pharyngitis in a penicillin - allergic patient.
• Cephalexin: A cephalosporin. There's a cross - allergy risk with penicillin, so it's not safe.
• Amoxicillin/clavulanic acid: Amoxicillin is a penicillin - type drug, so it's not safe for a penicillin - allergic patient.

Answer:

B. Azithromycin
