Which of the following is NOT a primary preventive measure for pressure ulcers?

• A. Pressure redistribution through devices and positioning
• B. Prolonged bed rest
• C. Regular turning schedule
• D. Adequate nutrition and hydration

Answer: (B)

Preventing pressure ulcers centers on reducing prolonged pressure on vulnerable areas and supporting tissue tolerance through pressure offloading, regular repositioning, and good nutrition and skin care. Using devices or proper positioning to redistribute pressure directly lowers the load on bony prominences like the sacrum and heels, which is essential to prevent ischemia and tissue damage. A regular turning schedule ensures no single area sustains pressure long enough to compromise blood flow. Adequate nutrition and hydration provide the building blocks for skin integrity and healing, helping tissues resist injury and recover if minor issues begin. Prolonged bed rest, by keeping someone immobile, tends to increase the duration of pressure on a few areas and the risk of shear and moisture problems, so it is not a preventive measure—it's a condition that raises risk and requires preventive strategies to counterbalance it.
