A nurse is providing teaching for a client who has hypertension and a prescription change from metoprolol to metoprolol/hydrochlorothiazide. Which of the following statements by the client indicates an understanding of the teaching?

A. This statement is incorrect because the combination of metoprolol (a beta-blocker) and hydrochlorothiazide (a diuretic) does not eliminate the need for weight management. Lifestyle changes, including diet and exercise, remain important for managing hypertension. B. The presence of extra letters in the name of the medication does not necessarily indicate a stronger dose. It refers to the additional drug (hydrochlorothiazide) included in the combination, which has a different mechanism of action than metoprolol alone. C. The combination of metoprolol and hydrochlorothiazide may result in fewer side effects for some clients because the diuretic effect can help manage fluid retention, which is common with beta- blockers. However, individual responses to medication vary. D. This statement is incorrect. The new combination medication includes an additional diuretic, which may require the client to make changes in their lifestyle, such as monitoring for signs of dehydration or changes in electrolyte levels.
