Final answer:
The most appropriate action for proper use of body mechanics is to stand with legs wide apart, improving stability and balance. Holding objects close, bending at the knees, and maintaining a wide base of support are key to preventing strain and injury.
Step-by-step explanation:
When demonstrating the proper use of body mechanics, a nurse teaching a group of nursing students should adhere to best practices for minimizing stress on the body and avoiding injury. Among the options provided, the most appropriate action would be to stand with legs wide apart. This stance improves stability and balance by widening the base of support and lowering the center of gravity, which is foundational for adequate body mechanics. Holding objects away from the body, keeping knees locked, or approaching work from the side are not recommended as they can increase the risk of strain or injury.
Stability and balance are imperative when lifting or moving objects or patients in the healthcare environment. Nurses often push carts or carry loads, and using correct body mechanics helps prevent back injuries and promotes safety and efficiency. Maintaining a wide base of support, bending at the knees instead of the waist, and keeping the object close are key principles illustrated, for example, by a nurse exerting force at a downward angle below the horizontal to move a cart.
