What is the characteristic appearance of a pressure ulcer located over bony prominences?

The characteristic appearance of a pressure ulcer located over bony prominences typically includes reddened, non-blanchable skin. This is often one of the earliest signs of a pressure ulcer or pressure injury, indicating localized damage to the skin and underlying tissue due to prolonged pressure. When pressure is applied to a bony area, blood flow can be restricted, resulting in redness that does not fade (non-blanchable) when pressure is removed. This indicates that the tissue is at risk and can progress to more severe stages of pressure injury if not addressed promptly.

Other options, while relevant in different contexts, do not describe this initial presentation of a pressure ulcer. Necrotic tissue suggests advanced tissue damage and is associated with more severe ulcers. Excessive drainage is typically a sign of infection or advanced ulceration, while a smooth, shiny appearance may indicate other pathologies but is not characteristic of the initial stages of pressure ulcers over bony prominences. Understanding these characteristics helps healthcare providers recognize and manage pressure injuries effectively, preventing further tissue damage.
