A resident with an open wound on the right lower leg with poor blood return through her veins is likely suffering from which type of ulcer?

The correct answer is a stasis ulcer, which typically occurs in individuals with venous insufficiency—a condition where blood does not return effectively through the veins. This insufficient blood flow can lead to pooling of blood in the lower extremities, resulting in increased pressure and damage to the skin.

A stasis ulcer usually appears on the lower legs and is often associated with swelling, aches, and discoloration of the skin. The presence of an open wound combined with poor blood return through the veins in this scenario aligns with the characteristics of a stasis ulcer, making it the most appropriate choice.

In contrast, an arterial ulcer occurs due to inadequate blood flow from the arteries, which presents differently and is usually found on the feet or toes. A pressure ulcer, also known as a bedsore, typically arises from prolonged pressure on the skin, usually over bony prominences, rather than from venous insufficiency. A skin tear involves a break in the skin due to friction, shear, or blunt force trauma, which does not relate to the circulatory issues described in this case.
