What feature characterizes the Braden Scale's friction and shear assessment?

1. Movement independence

2. Moderate to maximum assistance required

3. Requires no assistance

4. Frequent sliding down

The correct answer is: Moderate to maximum assistance required

The characterization of friction and shear on the Braden Scale focuses on how an individual's mobility and ability to reposition themselves affect the risk of pressure injuries. The correct choice highlights that individuals who require moderate to maximal assistance are more susceptible to friction and shear forces because their immobility can lead to skin breakdown. When a person cannot move independently or requires significant help to change positions, the likelihood of skin injuries increases due to the forces exerted on the skin and underlying tissues during movement. In such cases, that friction and shear (which can occur when the skin slides over a supporting surface) can lead to damage, particularly over bony prominences. The other options either represent levels of independent mobility or situations where assistance isn't necessary. However, they do not accurately reflect the connection between the level of assistance needed and the increased risk of friction and shear, which is why the response focusing on the need for moderate to maximum assistance is the most relevant and correct in assessing the potential for skin injury in the context of the Braden Scale.
