Final answer:
Rotation maneuvers taught by nurses and physical therapists in long-term care facilities can help residents diminish the risk of injury from falling backwards.
Step-by-step explanation:
A nurse helps a physical therapist teach residents in a long-term care facility how to diminish the risk of injury from a fall by teaching them rotation maneuvers to help them avoid falling backwards. This is because the feet are not very long and muscles are used extensively to balance the body in the front-to-back direction. While bending as shown, stability is increased by lowering the center of gravity and also increased if the base is expanded by placing the feet farther apart, which is an example of a stance with feet pointing laterally and upper limbs extended out at a ninety-degree angle from the torso.
