A nurse is making assignments for staff on an inpatient unit. Which of the following tasks can a nurse legally delegate to assistive personnel?

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.

Choice A reason: Cheyne-Stokes respirations, alternating hyperventilation and apnea, indicate neurological dysfunction or end-of-life changes in brain tumor patients, not pain. This reflects brainstem involvement, requiring respiratory management rather than analgesics, as it is a physiological response to disease progression in palliative care.
Choice B reason: Mottled skin signals poor perfusion or impending death, common in palliative care as circulation declines. It is not a pain indicator but a sign of systemic shutdown, requiring comfort measures like warmth, not analgesics, which are irrelevant to this physiological change in terminal illness.
Choice C reason: Constricted pupils may reflect opioid effects or neurological changes in brain tumor patients but do not directly indicate pain. They suggest autonomic or brainstem dysfunction, necessitating neurological assessment, not immediate pain medication, in palliative care where comfort is prioritized based on clear pain cues.
Choice D reason: Grimacing indicates pain in palliative care patients with brain tumors, reflecting physical discomfort. As a facial expression of distress, it signals the need for analgesics to improve comfort and quality of life, aligning with palliative goals to manage pain effectively in end-stage disease.
