Final answer:
Residents in wheelchairs need to be re-positioned every 2 hours to prevent pressure ulcers by redistributing pressure and promoting blood flow, using the right support surfaces and correct positioning techniques.
Step-by-step explanation:
Residents in wheelchairs should be re-positioned at least every 2 hours to prevent the development of pressure ulcers. This is critical because individuals who have limited mobility and are unable to change positions independently are at risk for skin breakdown, which can lead to serious complications. Pressure ulcers, also known as bedsores, are areas of damaged skin and tissue that develop when sustained pressure cuts off circulation to vulnerable parts of the body, especially the skin over bony areas.
Re-positioning helps to redistribute pressure and promote blood flow. It is also essential to use proper support surfaces and ensure the resident is sitting or lying in a good position. Caregivers should be trained in the correct techniques for moving and re-positioning residents to minimize discomfort and avoid injury.
