A nurse is reinforcing teaching with a client who has peripheral vascular disease. Which of the following instructions should the nurse include in the teaching?

Choice A reason: Walking promotes collateral circulation in peripheral vascular disease, improving blood flow and reducing claudication. Regular exercise strengthens muscles and enhances perfusion, mitigating ischemic symptoms. This is a key instruction, as it directly addresses arterial insufficiency, supporting functional status and cardiovascular health in affected clients. Choice B reason: Knee-length stockings may restrict blood flow in peripheral vascular disease, especially arterial insufficiency, worsening ischemia. Compression is used for venous disease, not arterial. This instruction is incorrect, as it could exacerbate symptoms, requiring teaching on avoiding tight clothing to maintain circulation. Choice C reason: Shopping for shoes in the morning is less relevant, as foot swelling in peripheral vascular disease occurs later in the day. Properly fitted shoes are important, but walking is a more direct intervention to improve circulation, making this a less critical instruction for managing the condition. Choice D reason: Elevating legs is appropriate for venous disease to reduce edema but may worsen arterial insufficiency in peripheral vascular disease by reducing blood flow to extremities. Walking is preferred to enhance perfusion, making leg elevation an incorrect instruction for clients with arterial pathology.
