Before administering risperidone for a client with schizophrenia, which test result should the nurse verify?

Risperidone is an atypical antipsychotic medication that is primarily metabolized by the liver. Before starting treatment, it is crucial to verify liver function studies to ensure that the liver is functioning properly, as impaired liver function can lead to increased levels of the medication in the bloodstream, potentially causing toxicity and adverse effects. Monitoring liver function helps to determine the appropriate dosage and assess whether the patient can safely metabolize the medication. Thus, confirming liver function tests is an important step in the administration of risperidone, making it the correct choice in this scenario.
