A nurse is planning to administer olanzapine 10 mg IM to a client who has schizophrenia. Which of the following actions should the nurse take?

A. Olanzapine, an antipsychotic medication, can cause serious side effects such as sedation, orthostatic hypotension, and even respiratory depression. Therefore, it is important to monitor the client for at least 3 hours after the injection to observe for any adverse reactions, especially given the potential for prolonged effects from the intramuscular injection. B. If a client reports hallucinations, the nurse should assess the client’s mental state and the effectiveness of the current treatment but should not withhold medication like olanzapine, as it is intended to manage symptoms of schizophrenia, including hallucinations. The nurse should instead consult with the provider about adjusting the treatment. C. Olanzapine can cause sedation and drowsiness rather than difficulty sleeping, particularly after an intramuscular injection. Therefore, instructing the client to expect difficulty sleeping would not be an accurate expectation. D. Olanzapine should be administered into the ventrogluteal or vastus lateralis muscle, not the deltoid muscle, due to the volume of the injection and to avoid complications. The deltoid muscle is not recommended for large-volume IM injections.
