A client diagnosed with schizophrenia is prescribed clozapine. The nurse teaches the client and family to call the physician immediately if:

Choice A Reason: Clozapine is known to cause agranulocytosis, a potentially life-threatening condition where the white blood cell count drops significantly, leading to a higher risk of infection. Patients on clozapine must have regular blood tests to monitor their white blood cell count. Any signs of infection, such as fever, sore throat, or flu-like symptoms, should be reported to a physician immediately as they could indicate agranulocytosis. Choice B Reason: A decrease in hallucinations is generally a positive sign indicating that the medication is working effectively. It is not a reason to call the physician immediately. Instead, this should be discussed during regular follow-up appointments to assess the overall effectiveness of the treatment. Choice C Reason: While a decrease in appetite can be a side effect of clozapine, it is not typically an emergency unless it leads to significant weight loss or malnutrition. This should be monitored and discussed with the physician during regular visits. If the decrease in appetite is severe or persistent, it may warrant a call to the physician, but it is not as urgent as signs of infection. Choice D Reason: Insomnia can occur with clozapine use, but it is usually managed with adjustments to the medication regimen or additional treatments for sleep. While it is important to address insomnia, it does not require immediate medical attention unless it severely impacts the patient’s well-being.
