Oregon Certified Nursing Assistant State Practice Exam

Which of the following is part of using proper body mechanics?

1. The nursing assistant should twist her back when carrying objects

2. The nursing assistant should push when possible, rather than lifting

3. The nursing assistant should use a narrow base of support

4. The nursing assistant should lift with her back, not her legs

The correct answer is: The nursing assistant should push when possible, rather than lifting

Using proper body mechanics is essential for maintaining personal safety and preventing injuries while performing physical tasks. The correct choice highlights the importance of pushing rather than lifting whenever feasible. This approach helps to reduce strain on the back and minimizes the risk of injury. When pushing an object, the nursing assistant can use their body's strength more effectively and maintain proper alignment, as they can engage larger muscle groups such as the legs and arms. This technique not only conserves energy but also helps in maintaining balance and stability, which are critical when handling heavy or awkwardly shaped items. In contrast, twisting the back while moving objects, using a narrow base of support, or lifting with the back rather than the legs increases the likelihood of injury. These actions compromise body alignment and place undue stress on the spine and surrounding muscles, leading to potential strains or other musculoskeletal injuries. Therefore, choosing to push rather than lift aligns with the principles of safety and proper body mechanics.
