A nurse is teaching about leg and foot care to a client who has peripheral vascular disease of the lower extremities. Which of the following Instructions should the nurse include?

In clients with peripheral vascular disease, protecting vulnerable tissue between toes is important because pressure and friction between toes can lead to skin breakdown, ulceration, and infection. Using lamb's wool between toes that rub together cushions the area and prevents this friction-related tissue damage. Wearing nylon socks is contraindicated because nylon does not absorb moisture and can cause excess sweating and skin maceration, increasing infection risk; cotton or wool socks are preferred. Compression stockings that extend over the knees are not routinely recommended for peripheral arterial disease because compression can further restrict already compromised arterial blood flow; compression is used for venous disease. Trimming toenails short and rounding the edges is incorrect; toenails should be trimmed straight across and not too short to prevent ingrown toenails and nail-edge trauma. These clients have impaired circulation, so even minor injuries can progress to serious wounds. Teaching should focus on preventing all forms of trauma, maintaining skin integrity, and promoting circulation — lamb's wool is a simple, safe intervention that directly fulfills the goal of preventing mechanical skin breakdown.
