A nurse is caring for several clients who have mental health disorders at an assisted-living facility. Which of the following clients should the nurse determine needs to be seen by a provider immediately?

A. Clozapine can cause agranulocytosis, a life-threatening drop in white blood cells, leaving the client highly vulnerable to infection. Flu-like symptoms (fever, sore throat, malaise) may be early warning signs and require immediate provider notification and WBC count monitoring. B. Olanzapine commonly causes orthostatic hypotension. Dizziness when standing is expected early in treatment and can often be managed with slow position changes, not an emergency. C. Thioridazine, like many antipsychotics, can cause sedation. Daytime drowsiness is a common side effect and not urgent. D. Chlorpromazine may cause GI upset such as nausea and vomiting. While bothersome, it is not immediately life-threatening unless severe or persistent.
