Which aging-related change most contributes to the risk of pressure ulcers?

• A. Thinning of the skin with loss of elasticity
• B. Decreased sweating
• C. Increased muscle tone
• D. Reduced bone density

Answer: (A)

The main factor is that aging weakens the skin’s structure, making it easier for pressure to cause damage. As people age, the skin becomes thinner and less elastic because collagen and elastin decline, and there is often reduced subcutaneous fat. This means the skin has less padding and less ability to recoil after being compressed, so sustained pressure over a bony area more readily reduces blood flow and leads to tissue breakdown. Because the skin and underlying tissues are more fragile, simple friction or shear from movement can also cause tears more quickly, and healing is slower in older adults. Other aging changes don’t affect pressure ulcer risk as directly. Decreased sweating alters moisture and temperature regulation but isn’t the primary factor in tissue breakdown from pressure. Increased muscle tone is not typical in aging (muscle mass and strength often decline). Reduced bone density affects bones rather than skin tolerance to pressure.
