When a resident is in bed, the person is re-positioned at least every:

The correct practice when caring for a resident in bed is to reposition them at least every 2 hours. This is done to prevent pressure ulcers, also known as bedsores, which can develop when pressure is consistently applied to the skin without relief. Prolonged pressure on specific areas of the body can impede blood circulation, leading to tissue damage.

Repositioning helps distribute body weight more evenly and reduces the risk of skin breakdown. By following a 2-hour schedule, caregivers can maintain better skin integrity and overall comfort for the resident. It's essential for nurse aides to be aware of the importance of mobility and positioning in maintaining residents' health and preventing complications associated with immobility.

The other options suggest either a less frequent repositioning schedule, which may not provide adequate prevention against skin issues, or a more frequent schedule that may not be necessary for all residents, depending on their individual needs and conditions.
