Which statement about pressure ulcers is true?

• A. They are a result of poor hygiene
• B. They are caused by heat exposure
• C. They are caused by dehydration
• D. They are caused by prolonged pressure on the skin

Answer: (D)

Prolonged pressure on the skin is what causes pressure ulcers. When a person’s weight presses against one spot for too long, the blood vessels in the skin and underlying tissues are compressed, reducing blood flow and leading to tissue damage and ulcers. This most often happens over bony areas such as the heels, sacrum, or hips. While moisture, friction, shear, and poor nutrition can make ulcers more likely or slow healing, they are not the direct cause; the trigger is the sustained pressure itself. Prevention focuses on relieving pressure through regular repositioning, using pressure-relieving surfaces, and maintaining skin care, hydration, and nutrition.
