A nurse is caring for a client who has a prescription for olanzapine. The nurse should monitor the client for which of the following manifestations as an expected response to this medication?

The correct answer is B: Decreased auditory hallucinations. Olanzapine is an antipsychotic medication used to treat symptoms of schizophrenia and bipolar disorder. It works by blocking dopamine and serotonin receptors in the brain, which helps reduce hallucinations. Monitoring for a decrease in auditory hallucinations is important as it indicates that the medication is working effectively. Choices A, C, and D are incorrect because olanzapine is not typically associated with a decrease in resting blood pressure, control of seizure activity, or increased energy level. It is important for the nurse to focus on monitoring the client's response to the medication and address any side effects or adverse reactions that may occur.
