A nurse is caring for a client. Exhibits For each assessment finding, click to specify if the assessment finding is consistent with an arterial ulcer, a venous ulcer, or a diabetic ulcer. Each finding may support more than one disease process.

Rationale: The pale wound bed indicates poor blood flow and ischemia, which is a hallmark of arterial ulcers. In diabetes, microvascular complications can also reduce tissue perfusion, sometimes producing a pale wound bed, though typically less pronounced than in primary arterial disease. Hair loss on the lower extremities develops with chronic arterial insufficiency because the tissues are not receiving adequate nutrients and oxygen. In diabetic patients, vascular changes and neuropathy can also contribute to thinning or loss of hair, although usually it is less extensive. Defined edges are characteristic of arterial ulcers, often described as “punched-out” and sharply demarcated from surrounding skin. Diabetic ulcers, especially those occurring on pressure points like the great toe or metatarsal heads, can also present with well-defined borders, making this feature overlap between the two ulcer types. A +1 posterior tibial pulse reflects diminished arterial blood flow, confirming impaired perfusion consistent with arterial disease. In diabetic patients, chronic vascular compromise can similarly reduce peripheral pulses, particularly when peripheral arterial disease coexists with neuropathy. Pain at the ulcer site is typically severe in arterial ulcers and often worsens with activity, such as walking, and improves with rest, reflecting ischemia. While diabetic neuropathy often reduces pain perception, some diabetic ulcers remain painful, especially if there is concomitant ischemia. A history of hypertension is a strong risk factor for arterial disease and contributes to vascular damage leading to ischemic ulceration. While hypertension is also common in patients with diabetes, it is less directly linked to ulcer formation in diabetic ulcers. Skin cool to touch is indicative of poor perfusion and is a hallmark of arterial ulcers. Although diabetes can alter skin temperature due to neuropathy, the coolness of the extremity is much more characteristic of arterial compromise than of diabetic ulcers alone.
