The presence of redness that disappears after pressure is relieved is an important sign of a potential pressure ulcer developing, often referred to as blanchable erythema. This indicates that there has been localized pressure on the skin, which may impede blood flow to that area. If the skin turns red when pressure is applied and returns to its normal color once that pressure is removed, this is a warning signal that the tissue is at risk. While the skin may still appear healthy at this stage, it is necessary to address the underlying issue of pressure to prevent further skin breakdown and the formation of an ulcer.

In contrast, other choices suggest different conditions; for instance, warm skin can indicate improved blood flow but may not directly point to a pressure ulcer. Healthy and intact skin shows no signs of damage but does not indicate impending risk. Dark discoloration on the skin can signify more advanced tissue damage or necrosis, which is a more severe condition than what the question addresses. Recognizing and acting on the early signs of pressure ulcers is vital for prevention and maintaining skin integrity.
