A nurse is providing teaching to a client who has hypertension and a new prescription for hydrochlorothiazide. Which of the following instructions should the nurse provide?

A. Hydrochlorothiazide is a thiazide diuretic that increases urine output. It should be taken early in the day to prevent nocturia (frequent nighttime urination). B. Clients should weigh daily, not weekly, to monitor for fluid loss or retention, which reflects therapeutic effectiveness. C. Muscle pain is not an expected side effect; however, muscle weakness or cramping could indicate electrolyte imbalances like low potassium. D. It is not necessary to take hydrochlorothiazide on an empty stomach; it can be taken with food to minimize GI upset.
