Which type of ulcer is characterized by arterial impairment?

  1. Venous ulcer.

  2. Pressure ulcer.

  3. Arterial ulcer.

  4. Diabetic ulcer.

The correct answer is: Arterial ulcer.

An arterial ulcer is specifically characterized by arterial impairment, which affects blood flow to the tissues. This type of ulcer typically occurs in areas where the blood supply is diminished due to narrowed or blocked arteries, often a result of peripheral artery disease. As it is mainly caused by inadequate blood flow, these ulcers frequently manifest on the lower extremities, particularly on the feet, toes, and sometimes the heels. The hallmark features of an arterial ulcer include a well-defined, irregular wound edge, often with a pale or necrotic base. The surrounding skin may appear cool to the touch, and patients often experience pain in the ulcerated area, especially when their legs are elevated, due to the compromised blood supply. In contrast, venous ulcers are related to impaired venous circulation, pressure ulcers result from prolonged pressure on the skin, and diabetic ulcers are often linked to neuropathy and poor circulation related to diabetes. Understanding these differences is crucial for proper assessment and treatment of wounds, making the distinction of arterial ulcers significant in wound care nursing.
