A 60-year-old patient with peripheral artery disease (PAD) reports increased leg pain while walking. Which nursing action would be most appropriate?

Choice A rationale Applying ice packs to the legs of a patient with peripheral artery disease (PAD) is contraindicated. Cold causes vasoconstriction, which further reduces the already compromised blood flow to the distal extremities. This can worsen ischemia and increase the risk of tissue necrosis or skin breakdown. Patients with PAD should actually avoid cold environments and use warmth (not hot) to encourage vasodilation, although direct heat should also be used cautiously due to potential sensory loss. Choice B rationale Instructing a patient with PAD to walk through the pain is incorrect advice for someone experiencing intermittent claudication. Claudication is a sign that the oxygen demand of the leg muscles is exceeding the supply provided by the narrowed arteries. Forcing the patient to continue walking while in pain can cause further tissue ischemia. The correct approach is a structured exercise program where the patient walks until pain occurs, rests, and then resumes walking. Choice C rationale Minimal sunlight exposure is not a relevant clinical intervention for the management of peripheral artery disease or intermittent claudication. While general skin health is important, sunlight does not have a direct impact on the atherosclerotic plaques within the arterial walls or the blood flow to the lower extremities. The focus of PAD management should be on smoking cessation, lipid control, and improving circulation through appropriate activity levels and medications rather than UV exposure. Choice D rationale Encouraging rest at intermittent periods is the standard nursing intervention for managing intermittent claudication in PAD. When the patient stops walking and rests, the oxygen demand of the muscles decreases, allowing the pain to subside as the limited blood flow catches up. This "stop and go" method of walking helps build collateral circulation over time. It balances the need for physical activity to improve vascular health with the necessity of preventing severe ischemic muscle pain.
