Following a ureterolithotomy, the client has a ureteral catheter in place. Which intervention should the nurse implement?

Choice A reason: Persistent pain after Herpes zoster suggests postherpetic neuralgia (PHN), a neuropathic condition from varicella-zoster virus damaging sensory nerves. Assessing pain intensity, location, and characteristics guides treatment with analgesics or anticonvulsants like gabapentin. This step differentiates PHN from other causes, ensuring targeted therapy to alleviate nerve pain and improve quality of life.

Choice B reason: Checking shingles vaccination status is irrelevant for current pain, as the client already had Herpes zoster. Vaccination prevents initial infection but does not treat PHN, which results from nerve damage during active infection. Pain assessment is critical to address neuropathic symptoms caused by viral-induced sensory nerve dysfunction, making this less urgent.

Choice C reason: A mental status exam evaluates cognition but is not indicated for PHN, a physiological condition from nerve damage, not a cognitive issue. Pain is neuropathic, driven by damaged sensory neurons, not psychological factors. Assessing pain directly addresses the client’s complaint, guiding treatment for nerve-related discomfort, making this action inappropriate.

Choice D reason: Teaching about phantom pain is incorrect, as phantom pain occurs post-amputation, not after shingles. PHN involves persistent nerve pain in the affected dermatome due to viral nerve damage. Misdiagnosing this could delay proper management, as pain assessment is needed to confirm PHN and initiate therapies like gabapentin, not phantom pain education.

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.
