What is a key strategy to prevent stasis ulcers?

Preventing stasis ulcers primarily revolves around ensuring proper circulation and protecting the skin, particularly in the lower extremities. The correct answer highlights the importance of avoiding injury to the legs and feet during care, as injuries can compromise the skin's integrity and lead to ulcer formation.

Stasis ulcers occur when blood flow is inadequate, leading to pressure and malnutrition of the skin, which can be exacerbated by injuries, friction, or prolonged pressure. By safeguarding the legs and feet against trauma, caregivers can help maintain skin integrity and promote adequate blood circulation.

Other strategies, while important in overall care, do not directly address the mechanical aspects of injury prevention. For example, inadequate blood supply to the legs is a risk factor for stasis ulcers but does not provide a strategy for prevention. Minimizing exposure to sunlight might apply to skin protection but is not specific to stasis ulcers. Encouraging prolonged bed rest can worsen conditions related to circulation, further increasing the risk of developing stasis ulcers. Hence, the focus on avoiding injury is crucial for prevention.
