NCLEX PN Practice Test Practice Question
The nurse is preparing to administer IV cefazolin to a newly admitted client with cellulitis. The nurse notes the client is allergic to amoxicillin. Which of the following actions should the nurse take next?
Correct Answer: D
Rationale: Clients with an allergy to penicillin antibiotics (eg, amoxicillin) can experience a cross-sensitivity reaction
to cephalosporin antibiotics (eg, cefazolin) because the medication molecules are structurally similar. The
nurse should first obtain more information by asking about the type of reaction the client experienced because
allergic reactions can range from mild to severe (Option 4)
Cephalosporins can be safely administered to clients with a history of mild allergic reaction to penicillin (eg,
rash) but are contraindicated for clients with a history of anaphylaxis.
