Which of the following is a risk factor for developing pressure ulcers?

• A. Immobility
• B. Balanced Nutrition
• C. Regular Exercise
• D. Adequate Hydration

Answer: (A)

Immobility increases risk for pressure ulcers because constant pressure over a body area—especially over bony prominences—reduces blood flow to the tissues. When someone cannot shift position or relieve pressure, the skin and underlying tissues become ischemic, and with time, tissue breakdown can occur. This is why turning and repositioning regularly, using pressure-relieving supports, and maintaining movement are key preventive strategies.

The other factors listed—balanced nutrition, regular exercise, and adequate hydration—actually help prevent ulcers by supporting skin health, circulation, and tissue resilience, not by causing ulcers. They contribute to stronger tissue and better healing, which is why immobility stands out as the risk factor in this scenario.
