Which finding suggests arterial insufficiency?

• A. Intermittent claudication.
• B. Edema with pitting.
• C. Warm skin.
• D. Varicose veins.

Answer: (A)

Intermittent claudication shows arterial insufficiency because during activity the leg muscles demand more blood, and narrowed or blocked arteries can’t supply enough oxygen-rich blood, causing cramping or pain that improves with rest. This pattern is a hallmark of peripheral arterial disease. The other findings point toward venous problems or non-ischemic states: edema with pitting comes from venous hypertension and fluid buildup, warm skin can occur with inflammation or adequate arterial flow, and varicose veins reflect venous valve failure rather than arterial blockage.
