A nurse is caring for a client who has a prescription for a low-potassium diet. Which of the following foods should be included in the diet plan?

Choice A reason: Limiting fluid and caffeine intake before bed is the most effective way to reduce nocturia, as it decreases bladder volume and irritation overnight. Caffeine is a bladder stimulant, and reduced fluids minimize urine production, directly addressing the patient’s frequent urination.

Choice B reason: Practicing Kegel exercises strengthens pelvic floor muscles, aiding stress incontinence, but nocturia is more related to bladder overactivity or volume. Limiting fluids and caffeine more directly reduces nighttime urination frequency, making this less effective.

Choice C reason: Leaving the bathroom light on improves safety but does not address the cause of nocturia. Reducing fluid and caffeine intake directly decreases urination frequency, while lighting is a secondary safety measure, making this less appropriate.

Choice D reason: Clearing the path to the bathroom enhances safety but does not reduce nocturia’s frequency. Limiting fluid and caffeine intake before bed more effectively minimizes nighttime urination, making environmental adjustments a secondary consideration for this issue.

Choice A reason: Black, tarry stool while taking ferrous sulfate may indicate gastrointestinal bleeding, a serious condition, rather than a normal side effect (greenish-black stool). This requires further questioning to rule out hemorrhage, making it the priority.

Choice B reason: Dizziness upon standing suggests orthostatic hypotension, a common issue that warrants monitoring but is less urgent than potential bleeding. It requires clarification but is not as critical as black stool.

Choice C reason: Taking medication with orange juice is generally safe, though it may affect absorption of some drugs. This is less concerning than black stool, which could indicate bleeding, making it a lower priority.

Choice D reason: Skipping a dose due to feeling fine indicates non-compliance, which needs education but is not immediately life-threatening. Black stool suggesting bleeding is more urgent, making this less critical for questioning.
