Answer to Question 2
C
Patients who have maintained bed rest for a long time may revert back to a favorite position. Frequently assess these patients, and turn them more often as needed. Not turning them places them at greater risk for complications of immobility. Not allowing the patient to lie on his preferred side limits the number of sides available for turning and decreases patient comfort. The purpose of assessment and turning is to prevent complications of immobility.
