A nurse is caring for a client who has chronic venous insufficiency. Which of the following areas should the nurse assess for the presence of a venous ulcer?

Rationale: A. This area is the lateral side of the the heel and is more commonly affected by arterial ulcers or pressure injuries. It is not the typical location for ulcers caused by venous insufficiency. B. This area is the area on the tip of toes and is not a typical site for venous ulcers. Ulcers in this location are commonly arterial or diabetic ulcers. C. This area is the area on the sole of the feet at the base of the big toe and is not a typical site for venous ulcers. D. This area is the medial malleolus, just above the inner ankle, which is the most common site for venous ulcers. Chronic venous insufficiency leads to venous stasis and increased pressure in this region, causing skin breakdown and ulceration.
