The nurse is caring for a client with urolithiasis who reports severe flank and abdominal pain. Which action should the nurse implement?

Choice A reason: Smoking exacerbates PAD via nicotine-induced vasoconstriction and endothelial damage, reducing blood flow and worsening atherosclerosis, especially post-MI. Cessation is critical to halt vascular damage, improve endothelial function, and prevent further MI or limb ischemia, addressing the primary pathophysiological driver of disease progression in this high-risk client.

Choice B reason: Reducing saturated fats and salt lowers LDL cholesterol and blood pressure, mitigating atherosclerosis in PAD and MI. However, smoking directly causes vasoconstriction and plaque progression, making cessation more urgent. Dietary changes are secondary, as nicotine’s immediate vascular effects pose a greater risk to perfusion and cardiovascular health.

Choice C reason: Trimming toenails short prevents injury in PAD, where poor perfusion impairs healing. However, smoking cessation is more critical, as nicotine’s vasoconstrictive effects directly reduce arterial flow, worsening ischemia. Nail care is a minor preventive measure compared to addressing smoking, the primary contributor to PAD’s pathophysiology.

Choice D reason: Applying a heating pad is contraindicated in PAD, as reduced sensation increases burn risk, and heat doesn’t improve arterial insufficiency. Smoking cessation is paramount, as nicotine exacerbates vasoconstriction, reducing blood flow and risking tissue necrosis. Cessation directly addresses PAD’s vascular pathology, making it the priority instruction.

Choice A reason: Imbalanced nutrition is unrelated to 150 mL residual urine, which indicates incomplete bladder emptying, often from detrusor dysfunction or obstruction. Nutrition affects overall health but does not cause retention. Residual urine increases infection risk due to stasis, making nutrition an irrelevant nursing problem for this urinary issue.

Choice B reason: Deficient fluid volume suggests dehydration, reducing urine output, not causing high residual volumes. Residual urine (150 mL) indicates retention from impaired bladder emptying, not fluid deficit. Hydration prevents stasis, but infection risk from retained urine is more immediate, as bacteria proliferate in stagnant urine.

Choice C reason: Residual urine of 150 mL signifies incomplete bladder emptying, often from obstruction or neurogenic bladder, leading to urinary stasis. This fosters bacterial growth, increasing urinary tract infection (UTI) risk. Including “risk for infection” addresses this pathophysiological concern, guiding interventions like catheterization to reduce infection likelihood.

Choice D reason: Urinary incontinence involves involuntary leakage, not retention, where the bladder fails to empty, as seen with 150 mL residual urine. Retention results from outflow obstruction or weak detrusor, distinct from incontinence’s loss of control, making this nursing problem inappropriate for the client’s condition.
