A nurse is initiating bladder retraining for a client who has urge urinary incontinence. Which of the following instructions should the nurse give the client?

A. Diuretics should be taken in the morning to reduce nighttime urination. Evening dosing increases nocturia and sleep disruption. B. Cranberry juice acidifies urine and may prevent infection; it is not contraindicated for incontinence unless otherwise prescribed. C. Scheduled voiding every 2–3 hours helps retrain bladder muscles, increase bladder capacity, and reduce urgency/frequency episodes. Over time, the intervals are gradually lengthened as control improves. D. Severe fluid restriction can lead to concentrated urine, bladder irritation, and increased infection risk. Adequate hydration supports urinary tract health.
