A nurse is providing discharge teaching to a client who is taking risperidone. Which of the following instructions should the nurse include in the teaching?

A. "This medication may increase your blood pressure." Risperidone typically does not cause an increase in blood pressure. In fact, it can cause orthostatic hypotension (a drop in blood pressure when standing), not an increase in blood pressure, so this statement is incorrect. B. "Avoid becoming overheated while taking this medication. "Risperidone, like other antipsychotics, can impair the body’s ability to regulate temperature, increasing the risk of overheating or heatstroke, especially in hot weather or during physical exertion. Clients should be advised to avoid overheating. C. "Flu-like symptoms are an expected adverse effect of this medication." Flu-like symptoms are not a common or expected side effect of risperidone. Common side effects include sedation, weight gain, and metabolic changes, but flu-like symptoms are not typical. D. "Muscle twitches can occur the first few weeks while taking this medication." While risperidone can cause movement disorders such as tremors or muscle stiffness (extrapyramidal symptoms), muscle twitches are not a specific or common side effect that typically occurs in the first few weeks. This statement could cause unnecessary concern for the client.
