Which positioning practice most helps prevent a sacral pressure ulcer?

• A. Offload the sacrum with side-lying positions and alternating-pressure surfaces
• B. Keep the patient in a fixed supine position
• C. Raise the head of bed to 90 degrees at all times
• D. Massage the sacral area hourly

Answer: (A)

Pressure ulcers form when tissue is subjected to prolonged pressure over a bony prominence, reducing blood flow and causing tissue damage. To prevent a sacral ulcer, the goal is to relieve pressure on the sacrum and minimize shear by redistributing weight. The most effective approach is offloading the sacrum by turning the patient into side-lying positions and using an alternating-pressure surface. Side-lying shifts the weight away from the sacrum to the dependent hip and shoulder, while an alternating-pressure mattress continually changes pressure areas to prevent prolonged compression, giving the sacral tissues a chance to recover. Keeping someone fixed in a supine position keeps constant pressure on the sacrum, increasing risk. Raising the head of the bed to 90 degrees at all times promotes sliding and shear and can worsen sacral loading. Massaging the sacral area hourly isn’t a reliable preventive measure and can cause friction injuries; prevention relies more on pressure redistribution and periodic relief rather than routine massage.
