The correct answer identifies pressure points, which are body areas that are more susceptible to developing pressure ulcers due to prolonged pressure on the skin. The heels are particularly vulnerable because they bear a significant amount of weight when a person is in a supine position, especially when mobility is limited.

The heels typically receive the most attention when it comes to preventative measures for pressure ulcers in healthcare settings, making them a primary focus for caregivers and nursing staff.
