What position should a nurse place a client at risk for pressure ulcers to reduce pressure on bony prominences?

The 30° lateral position is the optimal choice for reducing pressure on bony prominences in clients at risk for pressure ulcers. This position allows for a more distributed weight on the mattress and decreases direct pressure on critical areas such as the heels, sacrum, and shoulders, which are especially vulnerable to pressure injuries.

By maintaining the client's body at a 30° angle, it helps relieve pressure while also providing comfort and promoting blood circulation in areas that might otherwise be compressed. This position can significantly lower the risk of skin breakdown over time, making it an effective preventive measure for individuals who are immobile or have limited mobility.

In contrast, the supine position places pressure directly on the back and other bony prominences like the heels, increasing the likelihood of developing pressure ulcers. The prone position can be beneficial for certain therapeutic interventions but is generally not used for long-term positioning in clients at risk for skin breakdown. Sitting upright does allow for dynamic movement but can increase pressure on the ischial tuberosities and other areas when sustained for long periods, thereby not being an ideal solution for preventing pressure ulcers.
