A nurse is planning to administer olanzapine pamoate 300 mg IM to a client. Which of the following actions should the nurse plan to take?

Choice A reason: Clients should not drive or operate machinery after receiving olanzapine pamoate due to the risk of post-injection syndrome and sedation. Choice B reason: Monitoring for sedation is essential after administration due to the risk of post-injection syndrome, which can mimic olanzapine overdose symptoms. Choice C reason: Excessive salivation is not a common side effect of olanzapine pamoate; sedation and delirium are more relevant concerns. Choice D reason: Olanzapine pamoate should be administered via deep IM injection in the ventrogluteal site, not the deltoid, to reduce the risk of vascular entry and post-injection syndrome.
