A nurse is caring for a client who is receiving amoxicillin IV for an infection. The client develops hives and complains of itching. What should the nurse's next action be?

A. The client is showing signs of an allergic reaction (hives and itching), which can rapidly progress to anaphylaxis, a life-threatening condition. The nurse’s priority action is to stop the medication immediately and assess the client’s airway, breathing, and circulation (ABCs). Early recognition and intervention are critical to prevent airway compromise, hypotension, and shock. B. Although Diphenhydramine may be administered to treat allergic symptoms, it is not the priority initial action. The medication must first be stopped and the client assessed to prevent worsening of the reaction. C. Notifying the healthcare provider is appropriate, but it is not the first action. Immediate nursing intervention to stop the drug and assess the client takes priority. D. Continuing the medication despite signs of an allergic reaction is unsafe and could lead to severe anaphylaxis. The medication must be discontinued immediately.
