Final answer:
Re-positioning a patient helps prevent pressure ulcers and relieves discomfort by redistributing pressure on the skin and promoting better circulation.
Step-by-step explanation:
Re-positioning the patient is necessary to prevent pressure ulcers and relieve discomfort. In healthcare settings, prolonged immobility can cause these ulcers, also known as bedsores, which occur due to constant pressure on certain areas of the body, compromising blood flow to the skin and underlying tissues. Regular re-positioning redistributes pressure on the skin and supports better circulation, contributing to patient comfort and the prevention of skin breakdown.
