A staff education nurse is evaluating a group of nurses during a new employee orientation on the use of proper body mechanics when lifting. Which of the following images indicates the appropriate use of ergonomic principles? A. B. C. D.

Rationale: Using proper body mechanics is vital to prevent injury and ensure safe lifting. Key principles include keeping the back straight and neutral to reduce spinal stress and bending at the knees and hips to engage stronger leg muscles rather than the lower back. Maintaining a shoulder-width stance provides stability, while holding objects close to the body decreases spinal strain. Lifting with the legs, not the back, further protects the spine. Twisting should be avoided—pivoting with the feet maintains alignment and reduces injury risk. Keeping the head and neck aligned with the spine improves posture and visual focus. Using smooth, controlled movements prevents muscle strain and dropped objects. Assessing an object’s weight before lifting helps determine if help or equipment is needed, preventing overexertion. Supportive footwear with a good grip ensures balance and minimizes fall risk. These ergonomic practices promote safety, reduce injuries, and are essential in both clinical and everyday environments.
