What corresponds with pain, weakness and pallor of the lower extremities?

• A. Venous stasis ulcers
• B. Intermittent claudication
• C. Peripheral artery disease
• D. DVT

Answer: (A)

Pain, weakness, and pallor in the lower extremities point to arterial insufficiency from peripheral artery disease. When leg muscles demand more blood during activity, narrowed or blocked arteries can’t supply enough oxygen, causing claudication-type pain and a sense of weakness. Pallor appears because arterial inflow is reduced, especially noticeable when the leg is elevated; color may return when the leg is dependent. Venous stasis ulcers come from venous insufficiency and typically show edema, skin discoloration, and ulcers rather than pallor. Deep vein thrombosis presents with swelling, warmth, and tenderness, not pallor. While intermittent claudication describes the pain pattern associated with PAD, the underlying condition that matches these signs is peripheral artery disease.
