Which term describes pressure-related skin damage that develops over time?

• A. Pressure ulcer
• B. Pressure injury
• C. Decubitus
• D. Bed sore

Answer: (A)

Prolonged pressure over a bony area reduces blood flow to the skin, leading to tissue damage that develops and worsens over time. The term that best fits this description in clinical practice is pressure ulcer, which denotes localized skin and tissue breakdown caused by sustained pressure and is commonly used to describe the progressive damage that occurs with ongoing pressure. While older or less precise terms exist—decubitus is an older synonym and bed sore is a colloquial label—the professional, time-related aspect of the injury is most clearly conveyed by pressure ulcer. (Note: some sources now prefer pressure injury to reflect broader forms of damage, but for this wording, pressure ulcer aligns with the described time-based deterioration.)
