What type of wound is typically caused by prolonged pressure over bony areas?

The correct answer is pressure ulcer. Pressure ulcers, also known as pressure sores or bedsores, develop as a result of sustained pressure on areas of the skin, particularly over bony prominences such as the heels, sacrum, and elbows. This pressure reduces blood flow to the area, leading to tissue ischemia and potential skin breakdown. Factors that increase the risk of developing pressure ulcers include immobility, inadequate nutrition, moisture, and friction.

In contrast, burns result from thermal, chemical, or electrical sources that damage the skin, and they are not related to pressure. Cut wounds arise from sharp objects causing lacerations that penetrate the skin, while traumatic injuries involve various forms of trauma such as impacts or falls but do not specifically relate to prolonged pressure on the skin. Pressure ulcers are distinct in their etiology and clinical management, emphasizing the importance of prevention through regular repositioning and skin care for at-risk individuals.
