How does routine repositioning benefit patients at risk for pressure injuries?

1. Increases skin hydration

2. Reduces the time factor

3. Decreases ventilation

4. Restricts blood flow to the wound

The correct answer is: Reduces the time factor

Routine repositioning of patients plays a critical role in preventing pressure injuries by effectively distributing body weight, thereby minimizing prolonged pressure on specific areas of the skin. This method not only helps to alleviate pressure points but also decreases the time skin is subjected to those pressures. As the skin and underlying tissues are constantly subjected to external forces, limiting the duration of pressure is essential in preventing ischemia and subsequent tissue damage. This approach facilitates improved blood circulation to the areas that have been de-prioritized during prior positioning, promoting oxygen and nutrient flow to the skin cells, which is crucial for wound healing and overall skin integrity. While hydration and ventilation are important for skin health, thorough repositioning primarily addresses the reduction of pressure over time, reinforcing its significance in pressure injury prevention strategies.
