Occurs when layers of materials, such as extra sheets or blankets, are placed over the surgical mattress or padding, diminishing the pressure-reducing properties of the surfaces

The answer is Negativity.

The pressure-reducing properties of the mattress or padding is diminished when extra linen is added on the mattress. It also cause rigidity. Thus, correct patient positioning is important to avoid negativity.

Correct positioning of the patient during surgical procedure does not compromise patient safety. There are positioning equipment so that the pressure is redistributed and optimum support and stability is provided. Correct positioning reduces the risk of positioning injuries, such as pressure ulcers that can lead to stage 4 ulcer.
