Question 1 of 5
A client with a history of anaphylactic reaction to penicillin receives a prescription for cephalexin 500 mg PO twice daily. Which action should the nurse take?
Correct Answer: B
Rationale: Cephalexin may cause cross-reactivity in penicillin-allergic clients, so monitoring for allergic reactions like rash or hives is critical. Administering without monitoring, contacting the provider immediately, or giving antihistamines prophylactically are less appropriate.
