Which measure helps increase arterial blood flow to the extremities in lower extremity arterial disease?

• A. Exercises that promote muscular activity
• B. Meticulous care of minor skin breakdown
• C. Elevation of the legs above the level of the heart
• D. Soaking the feet in hot water each day

Answer: (A)

The main idea is that improving blood flow to the legs in peripheral arterial disease comes most effectively from activities that move the leg muscles. When you exercise, the leg muscles contract and compress the surrounding arteries, acting like a pump that helps push blood through narrowed vessels. This skeletal muscle pump, along with repeated exercise over time, promotes better collateral circulation and improves endothelial function, leading to increased perfusion to the extremities and reduced claudication.

Meticulous skin care is important for preventing ulcers, but it doesn’t raise arterial inflow. Elevating the legs above heart level can decrease arterial pressure at the feet and may worsen distal perfusion in PAD. Soaking the feet in hot water isn’t a reliable or safe way to boost arterial blood flow and can risk burns, especially if sensation is reduced.
