California Certified Nursing Assistant (CNA) Practice Exam

In what situation should a nursing assistant use proper body mechanics?

1. When lifting heavy objects

2. When standing still for long periods

3. When sitting at the bedside

4. When writing in the chart

The correct answer is: When lifting heavy objects

Using proper body mechanics is essential to ensure safety and prevent injury, particularly when handling heavy objects. This involves utilizing techniques that maintain balance, reduce strain on the body, and support the use of strength efficiently. Good body mechanics during lifting can significantly minimize the risk of musculoskeletal injuries, which are common among healthcare workers who may repeatedly lift patients or equipment. While standing still for long periods, sitting at the bedside, or writing in the chart may also require attention to posture and ergonomics, they do not carry the same immediate risk of injury as lifting heavy objects does. In contrast to lifting, the other scenarios focus more on maintaining a comfortable and sustainable position rather than maximizing physical safety during potentially hazardous movements. Thus, recognizing the importance of body mechanics in lifting is crucial for maintaining both personal health and effective patient care.
