When inspecting the sacral and ischial regions, what is the earliest sign of a pressure injury visible on inspection?

• A. Macerated tissue
• B. Localized redness
• C. Pale or blanched skin
• D. Decubitus ulceration

Answer: (B)

The earliest sign of a pressure injury in the sacral and ischial region is a localized red area caused by capillary dilation under intact skin. This simple redness marks the beginning of tissue damage and is what clinicians look for before any skin breakdown occurs. In exam terms, this corresponds to the initial Stage 1 change. If you press on the red area and the color does not fade (nonblanchable redness), that confirms that tissue is being stressed even though the skin hasn’t broken. If the redness blanches with pressure, the skin is still intact and the injury has not begun. Other signs—maceration from moisture, pale or blanchable skin, or an actual ulceration—represent further progression or different concerns and are not the earliest visible sign.
