What does shearing refer to in patient care?

Shearing refers to a situation where the skin adheres to a surface, such as a bed or chair, while the underlying muscles and tissues move in the opposite direction. This action can occur when a patient is repositioned or moved without adequate lifting techniques. As a result, this can lead to damage to the skin and the underlying tissues, increasing the risk of pressure ulcers. Understanding shearing is crucial for providing effective care because it emphasizes the importance of proper patient handling and the need to minimize friction and shearing forces during mobility or repositioning.

Other options focus on various aspects of patient care but do not accurately define shearing. For instance, excessive movement refers to general patient mobility, which is not specific to the mechanics of shearing. Lifting a patient involves raising them from a surface safely and does not imply the frictional forces at play in shearing. Lastly, applying dressings to wounds is a separate aspect of wound care management and is unrelated to the definition of shearing.
