Which of the following is a primary non-pharmacologic measure for peripheral arterial disease?

• A. Limb/foot care
• B. Prolonged bed rest
• C. Avoiding walking
• D. High-sodium diet

Answer: (A)

In peripheral arterial disease, protecting the legs and feet from injury is a key non-drug strategy because reduced blood flow makes tissues more vulnerable to ulcers and infection. Meticulous limb and foot care helps prevent breaks in the skin from becoming serious problems. Practical steps include inspecting feet daily for cuts, blisters, redness, or swelling; washing with warm (not hot) water and drying thoroughly; moisturizing to prevent cracked skin but not between the toes; wearing well-fitting, protective footwear and avoiding tight socks; trimming nails straight across and avoiding cutting nails too short; protecting feet from extreme temperatures and never walking barefoot; and seeking prompt care for any wound or sign of infection.

Prolonged bed rest would limit movement and actually worsen circulation and function; encouraging walking within tolerance is beneficial for improving collateral circulation. A high-sodium diet does not address the limb-wide protection and activity goals that PAD management targets.
