Oregon Certified Nursing Assistant State Practice Exam

Which practice is an example of using proper body mechanics?

1. The NA should twist at the waist when lifting objects

2. The NA should stand with her legs shoulder-width apart

3. The NA should lift objects, rather than pushing them

4. The NA should carry objects away from her body

The correct answer is: The NA should stand with her legs shoulder-width apart

Standing with legs shoulder-width apart is an example of using proper body mechanics because it provides a stable base of support, which is essential for maintaining balance and stability when lifting or moving objects. This position distributes the weight of the body evenly and helps the individual to engage the core muscles effectively, reducing the risk of injury. Proper body mechanics are crucial as they help to prevent strain on the back and other parts of the body during physical activities. In contrast, other practices mentioned would compromise safety. Twisting at the waist when lifting can put undue stress on the spine, potentially leading to injuries. Lifting objects instead of pushing them may not always be the safest option, as pushing can often be easier on the body when done correctly. Carrying objects away from the body can also create additional strain on the back and arms, making it harder to maintain balance and control. Therefore, the practice of standing with legs shoulder-width apart is aligned with the principles of body mechanics essential for safe patient handling in a healthcare setting.
