A nurse is providing teaching to a client diagnosed with schizophrenia and is prescribed haloperidol (Haldol). Which of the following information should the nurse include in the teaching?

The correct answer is D: You may experience dizziness upon standing while taking this medication. This is important information to include because haloperidol can cause orthostatic hypotension, leading to dizziness upon standing. This is a common side effect that the client should be aware of to prevent falls. Option A is incorrect because haloperidol is not used to treat OCD. Option B is incorrect because excessive salivation is not a common side effect of haloperidol. Option C is incorrect because it is crucial not to stop taking antipsychotic medications abruptly without consulting a healthcare provider.
