E. List 4 sites on the body where pressure ulcers commonly occur.

1. Sacrum (tailbone)
2. Heels
3. Ischial tuberosities (sit bones)
4. Elbows

F. Briefly describe 2 risk factors for the development of pressure ulcers.

1. Immobility: Prolonged immobility, such as being bedridden or wheelchair-bound, prevents individuals from shifting their weight. This leads to sustained pressure on bony prominences, compressing blood vessels and causing a deficiency of blood flow to the tissues, which can result in tissue damage and ulcer formation.
2. Reduced Sensation: Conditions like spinal cord injury, neuropathy, or stroke can impair a person's ability to feel pain or discomfort. Without the sensation of pressure, individuals may not be aware of the need to change position, leading to prolonged pressure on vulnerable areas and subsequent tissue breakdown.
