Lymphology Association of North America (LANA) Practice Exam

In relation to wound care, what is a common characteristic of wounds from venous insufficiency?

1. They are often deep and painful

2. They tend to heal quickly without intervention

3. They are usually irregular and may be covered in slough

4. They typically have well-defined edges

The correct answer is: They are usually irregular and may be covered in slough

Wounds resulting from venous insufficiency are commonly irregular in shape and can be accompanied by slough, which is a type of necrotic tissue that appears yellow or white. This characteristic is due to the underlying pathology of venous insufficiency, where venous return is impaired, leading to increased pressure in the veins and resulting in skin changes and ulceration. The irregularity of the wound shapes reflects the way that fluid leakage and tissue damage occur in a more chaotic manner, often influenced by the individual's anatomy and positioning. Additionally, venous ulcers are often located in areas with the most pressure, such as the medial aspect of the lower leg, which contributes to their irregular edges. The presence of slough indicates that the wound is potentially chronic and has not effectively progressed through the healing phases, requiring appropriate management to facilitate healing. Understanding the typical characteristics of venous insufficiency wounds aids in proper assessment and treatment, which is essential for successful wound care management.
