What intervention should a nurse implement to assist an older adult at risk of pressure ulcers?

Using low-air-loss mattresses is an effective intervention for assisting an older adult at risk of pressure ulcers. These specialized mattresses are designed to provide a better distribution of body weight, reduce moisture, and enhance airflow, which helps to decrease pressure on the skin and bony prominences. Proper pressure redistribution is crucial for preventing the development of pressure ulcers, particularly in older adults who may have fragile skin and decreased mobility.

Low-air-loss mattresses help to maintain skin integrity by minimizing skin breakdown and promoting comfort. This is especially important for individuals who are immobile or have limited ability to change positions independently. They work by using a system of air-filled bladders that can adjust pressure according to the patient's needs, thus preventing prolonged pressure on any one area of the body.

In contrast, keeping the head of the bed elevated at a greater angle can increase pressure on certain areas and may lead to shearing forces, which can exacerbate the risk of skin breakdown. Encouraging daily massages over bony prominences does not prevent pressure ulcers and may, in fact, increase the risk of damage to the skin. Adjusting the client's position every three hours may be beneficial; however, more frequent repositioning is typically recommended to effectively reduce pressure buildup in vulnerable areas.
