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?

Choice A reason: Taking diuretics with the evening meal increases nighttime urination, worsening urge incontinence by stimulating bladder activity during sleep. Diuretics should be taken earlier (e.g., morning) to align with daytime voiding schedules, reducing urgency episodes. This instruction is counterproductive for bladder retraining, making it inappropriate. Choice B reason: Planning to urinate every 3 hours while awake establishes a scheduled voiding regimen, a key component of bladder retraining. This helps condition the bladder to delay urgency, reducing involuntary contractions and improving control. It aligns with evidence-based strategies for managing urge incontinence, making it the correct instruction. Choice C reason: Limiting fluid intake to 1 liter per day risks dehydration and concentrated urine, which can irritate the bladder and worsen urge incontinence. Adequate hydration (2-3 L/day) supports bladder health and retraining by maintaining normal urine volume, making this instruction harmful and incorrect. Choice D reason: Performing Kegel exercises once daily is insufficient for effective bladder retraining. Multiple daily sets (e.g., 3-4 times) strengthen pelvic floor muscles, improving bladder control. This frequency is too low to achieve therapeutic benefits for urge incontinence, making it less effective than scheduled voiding.
