A nurse is assessing a client who is taking clozapine. For which of the following adverse effects should the nurse monitor and report to the provider?

A. Rhinitis is a mild, non-serious side effect of clozapine and does not require immediate reporting. B. A sore throat can indicate agranulocytosis, a serious adverse effect of clozapine that involves a dangerously low white blood cell (WBC) count. Clients may also present with fever and malaise. This requires immediate notification and discontinuation of the medication. C. Headache is a common but mild side effect of many psychotropic medications and does not signal a hematologic emergency. D. Tinnitus is not typically associated with clozapine use.
