A nurse is caring for a client who has schizophrenia and is receiving clozapine. For which of the following findings should the nurse monitor to determine if the medication is having a therapeutic effect?

A. Clozapine is an antipsychotic medication commonly used to treat schizophrenia. Reduction in auditory hallucinations is a positive therapeutic outcome indicating the medication's efficacy in managing psychotic symptoms. B. While clozapine may have antiepileptic properties, it's primarily used for its antipsychotic effects rather than controlling seizures. C. Weight gain is a common side effect of clozapine rather than an indicator of therapeutic effect. D. Clozapine is associated with the potential for agranulocytosis, a severe adverse effect characterized by a decreased white blood cell count, but this is not a measure of therapeutic effect.
