Changing a patient's position every two hours is a critical practice for preventing pressure sores, which are serious and painful injuries that can occur when there is constant pressure on certain areas of the skin, typically over bony prominences. This two-hour interval allows for adequate circulation and reduces the risk of skin breakdown.

Prolonged pressure on the skin can lead to friction, moisture accumulation, and impaired blood flow, all of which increase the likelihood of pressure ulcer formation. By repositioning patients regularly, caregivers can promote better blood circulation, relieve pressure points, and enhance overall comfort. This practice is particularly important for individuals who are immobile or have limited mobility, as their risk for skin integrity issues is significantly greater.

The other options suggest time frames that may not effectively mitigate these risks. For instance, changing a position every hour might be excessive for stable patients, while changing once a shift does not account for individual needs and risks. Similarly, extending the time to every three hours can lead to increased risk for developing pressure sores, as this timeframe does not ensure sufficient relief from pressure.
