Which features characterize arterial wounds?

Arterial wounds, often resulting from poor blood circulation due to peripheral artery disease, are characterized by specific features. Among these, the circular or "punched out" appearance, along with the presence of minimal exudate, is a hallmark. This description aligns with the nature of arterial ulcers, as they generally develop over bony prominences or areas subjected to pressure due to the lack of blood flow, which affects the wound healing process.

The wounds frequently exhibit smooth edges and a well-defined border, showcasing how the tissue has been lost due to inadequate perfusion. Because arterial ulcers are not associated with significant exudate, and typically have dry, necrotic tissue, they are distinct from other types of wounds such as venous ulcers, which often are more moist and have irregular borders with heavy exudate. This makes the features described in option C accurately represent the typical presentation of arterial wounds.
