Correct Answer is B

Explanation

A. Swelling of the lower extremity can create a wound that is difficult to heal. Swelling typically relates to venous ulcers, not arterial ulcers, which are caused by reduced blood flow.

B. Decreased blood flow to the area can cause the wound and decrease the healing. Peripheral artery disease causes decreased blood flow, leading to poor oxygenation and slow healing of arterial ulcers.

C. Lower extremity compression stockings likely caused the wound to occur. Compression stockings are used in venous insufficiency and do not cause arterial ulcers.

D. Increased blood sugar associated with the condition is likely the cause of the wound not healing. While high blood sugar can impair healing, decreased blood flow is the primary cause of arterial ulcers in PAD.

A. Warm extremities B. Intermittent claudication C. Darkened skin color near extremities D. Edema

Correct Answer is B

Explanation

A. Warm extremities. PAD typically leads to cold extremities due to poor blood flow.

B. Intermittent claudication. Intermittent claudication, or muscle pain during exercise, is a classic symptom of PAD caused by limited blood supply to the muscles.

C. Darkened skin color near extremities. Darkened skin is more common in venous insufficiency, not PAD. PAD can cause pale or bluish skin.

D. Edema. Edema is typically associated with venous insufficiency, not PAD.
