A nurse is teaching a client who has an ileostomy about the care of their stoma. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: Catheter placement for a nontunneled central venous access device is typically confirmed by X-ray, not a CT scan, to verify tip placement in the superior vena cava. CT scans are less common due to higher radiation and cost, making this statement inaccurate for standard practice.
Choice B reason: Elevating the head as high as possible during insertion is incorrect, as the Trendelenburg position (head down) is often used to distend veins and reduce air embolism risk. High head elevation could complicate insertion and increase complications, making this instruction inappropriate.
Choice C reason: Flushing the catheter with saline daily maintains patency, preventing clots and ensuring functionality of the nontunneled central venous access device. This is a standard care instruction, reducing infection and occlusion risks, and aligns with evidence-based protocols for central line maintenance, making it correct.
Choice D reason: Lying flat for 24 hours post-procedure is not required for nontunneled central venous catheters. Patients may need brief bed rest (e.g., 30 minutes) to prevent bleeding, but 24 hours is excessive and not evidence-based, making this instruction incorrect and overly restrictive.

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.
