A nurse is providing instructions about foot care for a client who has peripheral arterial disease. The nurse should identify that which of the following statements by the client indicates an understanding of the teaching?

Peripheral arterial disease (PAD) is a condition characterized by reduced arterial blood flow to the extremities due to atherosclerotic narrowing of peripheral vessels. This leads to tissue ischemia, delayed wound healing, and increased risk of skin breakdown, especially in the lower extremities. Foot care is a critical component of management to prevent injury, infection, and ulceration. Patient education focuses on protecting the skin, improving circulation, and avoiding further vascular compromise. A. Using a heating pad on a low setting is unsafe in clients with PAD because reduced sensation and impaired circulation increase the risk of burns and tissue injury. Clients may not accurately perceive temperature changes, leading to thermal damage. Therefore, external heat sources should be avoided. B. Applying a lubricating lotion to dry or cracked areas of the feet is appropriate because it helps maintain skin integrity and prevents fissures that could become entry points for infection. In PAD, careful skin care is essential due to poor wound healing and reduced tissue perfusion. Lotion should be applied gently, avoiding areas between the toes to prevent maceration. C. Soaking feet in hot water is contraindicated because it can cause burns due to decreased sensation and further impair circulation. Hot water may also increase tissue damage in ischemic limbs. Additionally, soaking can lead to skin breakdown and infection risk in clients with PAD. D. Elevating the feet in a recliner for prolonged periods is not recommended in PAD because it can further reduce arterial blood flow to the lower extremities. Unlike venous insufficiency, PAD requires dependent positioning to promote perfusion. Elevation may worsen ischemia and increase pain.
