Which intervention is appropriate for reducing the risk of pressure ulcers?

Changing the client's position every two hours is a critical intervention in reducing the risk of pressure ulcers. This practice helps to alleviate pressure on specific areas of the body that are susceptible to skin breakdown, particularly in individuals who may be immobile or spend extended amounts of time in one position. By regularly repositioning the client, it promotes blood circulation to the skin and underlying tissues, preventing ischemia and subsequent tissue injury that can lead to pressure ulcers.

Regular repositioning is particularly important for individuals with limited mobility, as the constant pressure on certain areas can impede blood flow and nutrition to the skin, making it more vulnerable to damage. This simple yet effective intervention is a fundamental component of pressure ulcer prevention protocols in various healthcare settings.

In contrast, the other options provided do not effectively contribute to the prevention of pressure ulcers. A low-protein diet may adversely affect skin integrity and healing. A firm mattress, while it can be beneficial in some cases, is not a blanket solution for preventing pressure ulcers, as comfort and proper support play crucial roles. Lastly, restricting fluid intake does not prevent pressure ulcers and can lead to other complications like dehydration or urinary tract infections.
