How often should patients with limited mobility be repositioned to prevent skin breakdown?

1. Every hour

2. Every 2 hours

3. Every 4 hours

4. Every 6 hours

The correct answer is: Every 2 hours

Patients with limited mobility should be repositioned every 2 hours to prevent skin breakdown, which is often referred to as pressure ulcers or bedsores. This recommendation is based on the understanding that prolonged pressure on any part of the body can impede blood flow and lead to tissue damage. Repositioning at this interval helps to redistribute weight and relieve pressure on vulnerable areas, such as the heels, sacrum, and elbows, which are more susceptible to breakdown. Repositioning every 2 hours is a standard practice in healthcare settings, particularly for those who are bedridden or have limited mobility due to medical conditions. This frequent movement is crucial for maintaining skin integrity and overall health, as it encourages circulation and promotes comfort for the patient. The other intervals are considered less effective in preventing pressure injuries. Repositioning every hour might be too frequent for some patients, potentially causing unnecessary strain or discomfort. On the other hand, allowing a patient to remain in one position for 4 or 6 hours significantly increases the risk of skin breakdown, as pressure on the same area for extended periods can result in serious complications. Thus, the 2-hour interval strikes a balance between promoting comfort and effectively preventing skin breakdown.
