Which statement from a client taking risperidone indicates a need for further teaching?

The statement indicating a need for further teaching is the one about needing to have weekly tests to monitor white blood cells. While monitoring white blood cell counts is important for patients on certain antipsychotics, such as clozapine, it is not a routine requirement for patients taking risperidone. Risperidone does carry a risk for side effects such as metabolic syndrome and extrapyramidal symptoms but does not necessitate frequent monitoring of white blood cell counts in the same way that other medications might.

Understanding the specific requirements for monitoring when on medications is crucial for safe and effective treatment. The other statements reflect awareness of the potential side effects associated with risperidone, including the need to report abnormal movements and muscle stiffness, as well as recommendations for managing dry mouth, which are common occurrences with antipsychotic medications. Therefore, the necessity for weekly white blood cell tests does not apply to all patients on risperidone, highlighting the need for better education on medication-specific monitoring requirements.
