A nurse is preparing to lift a heavy object.
Which of the following actions by the nurse indicates an understanding of body mechanics?

Choice A rationale:

Keeping the feet together when lifting an object is not a proper body mechanics technique. It can lead to instability and an increased risk of injury because the base of support is not wide enough. Therefore, this choice does not indicate an understanding of body mechanics.

Choice B rationale:

Bending at the hip when lifting is also an incorrect body mechanics technique. Proper body mechanics involve bending at the knees and keeping the back straight to reduce the risk of back injuries. Bending at the hips can strain the lower back, making it an incorrect choice.

Choice C rationale:

Twisting the spine when lifting is a harmful practice in body mechanics. Twisting the spine can lead to spinal injuries, especially when lifting heavy objects. Proper body mechanics emphasize keeping the spine aligned and not twisting during lifting. Therefore, this choice does not indicate an understanding of body mechanics.

Choice D rationale:

Standing close to the object being moved is the correct body mechanics technique. This choice demonstrates an understanding of proper body mechanics because it reduces the strain on the back and minimizes the effort required to lift a heavy object. Keeping a wide base of support and using the leg muscles rather than the back muscles are essential principles of proper body mechanics. This is the correct choice. .
