Which factors contribute to pressure injuries?

• A. Age, Immobility, Physical Condition, Chronic Illness, Nutritional status, Incontinence, Mental status, Lack of turning, and Medical Devices
• B. Water intake only
• C. Only age
• D. Noise level

Answer: (A)

Prolonged pressure over a bony area reduces blood flow to the skin and underlying tissue, leading to ischemia and tissue breakdown. Many things can tilt the balance toward injury, not just one factor. The strongest answer recognizes that a wide range of conditions can increase risk by either increasing pressure exposure or reducing tissue tolerance and healing. Immobilization or not turning regularly means the same spots stay pressed against a surface longer, so blood flow stays obstructed. Age makes skin thinner and less resilient, with slower healing, so it’s easier for damage to start and progress. Physical condition and chronic illness affect circulation, nutrition, and the body’s ability to repair itself, all of which raise susceptibility to injury. Nutritional status is key because protein and calories are needed for skin integrity and wound healing; malnutrition weakens the skin and delays recovery. Incontinence introduces moisture that Macerates the skin, making it more fragile and prone to breakdown when friction or pressure occur. Mental status matters because confusion or cognitive impairment can hinder a person’s ability to reposition themselves or report discomfort, so protective repositioning is less likely. Medical devices can create constant localized pressure or friction (taping, tubing, braces), contributing to injury if not well managed and regularly inspected. The other options narrow factors too much—water intake alone ignores pressure mechanics and most contributors, age alone misses immobility, and noise level has no relation to tissue viability. This broader set of factors best explains why pressure injuries develop and why thorough prevention targets multiple areas.
