Pressure ulcers can be prevented by:

1. Repositioning the client every 2 hours

2. Only using soft mattresses

3. Avoiding any physical activity

4. Providing extra blankets

The correct answer is: Repositioning the client every 2 hours

Repositioning the client every 2 hours is essential in preventing pressure ulcers. This practice helps to relieve pressure on vulnerable areas of the body, especially for those who are immobile or spend long periods in one position. Continuous pressure on the skin can cause blood flow to diminish, leading to tissue damage and ulcer formation. By regularly changing a patient's position, you allow blood to circulate more effectively, which promotes skin health. While using soft mattresses can contribute to comfort, they are not the sole solution for preventing pressure ulcers. Avoiding any physical activity can actually worsen the situation, as movement encourages circulation, which is vital for skin integrity. Providing extra blankets may offer warmth but does not directly address the risk factors associated with prolonged pressure on the skin. Thus, regular repositioning stands as a clear preventive measure against pressure ulcers.
