What defines a 'Stasis Ulcer'?

A stasis ulcer, often referred to as a venous ulcer, is primarily characterized by its development resulting from venous hypertension. This condition occurs when the veins in the lower extremities do not effectively return blood to the heart, leading to increased pressure and fluid buildup in the surrounding tissues. Over time, this elevated pressure can cause the skin to break down, resulting in an ulcer.

Understanding the underlying cause is crucial, as stasis ulcers typically arise in areas where the blood flow is compromised due to venous issues, making option C the correct definition. It emphasizes the relationship between venous hypertension and the formation of ulcers, which is a fundamental aspect of diagnosing and treating this type of wound.

The other options provide related but distinct points. Arterial insufficiency, for instance, leads to ulcers known more commonly as arterial ulcers, not stasis ulcers. Non-healing wounds due to poor blood flow might encompass a broader category and are not specific to venous stasis. Finally, stating that all ulcers in the lower extremities fall under this definition ignores that lower extremity ulcers can stem from various causes, including arterial, neuropathic, or pressure-related factors. Thus, the specificity in how stasis ulcers are defined in relation to ven
