Which of the following strategies helps prevent pressure ulcers?

The main idea tested is that preventing pressure ulcers relies on actively reducing and redistributing pressure on vulnerable areas. Pressure ulcers develop when sustained external pressure over a bone area exceeds capillary blood flow, leading to tissue ischemia. Keeping a patient immobile doesn’t prevent this; it often sustains the exact load that causes damage. Frequent repositioning helps by continually moving the load to different areas, giving tissues a chance to recover and boosting blood flow. Repositioning every two hours is a common approach to relieve pressure on high-risk sites like the sacrum, heels, and trochanters. Coupling this with pressure-relieving surfaces—mattresses or overlays designed to lower interface pressure and reduce shear—directly mitigates the forces that initiate ulcers. While moisture management is important (excess moisture weakens skin), focusing on moisture alone won’t prevent ulcers if pressure isn’t relieved. Aggressive turning without monitoring isn’t ideal because timing and technique need to respond to the patient’s skin condition and tolerance; a plan that includes regular relief of pressure on conjunction with appropriate surfaces is more protective.
