HESI Introduction to Allied Health (AH) Practice Test

Relieving prolonged pressure over a bony area is the key to preventing sacral ulcers. Positioning the patient prone with a small pillow under the diaphragm helps shift weight away from the sacral region. In this setup, the chest and abdomen are supported, which reduces direct contact and pressure on the sacrum, while the pillow provides a comfortable angle that aids off-loading. This allows blood flow to the tissues in the sacral area to improve and helps prevent ischemic injury. Remember to pair this with regular repositioning, a pressure-relieving mattress, and good skin care to keep skin clean and dry. Other options don’t off-load the sacrum as effectively and can even increase risk: remaining in a high-Fowler’s position continues pressure on the buttocks and sacrum; massaging the sacral area hourly isn’t appropriate and can cause tissue damage; leaving the patient to reposition themselves may not relieve pressure promptly and can lead to falls.
