An occupational health nurse is providing teaching to a group of factory workers about proper lifting techniques. Which of the following statements should the nurse make?

A. "Keep objects away from your center of gravity while lifting.": Lifting objects away from the body increases strain on the back and risks injury. Objects should be kept close to the body to reduce musculoskeletal stress. B. "Keep your feet together to provide a tight base of support.": A narrow stance decreases stability and increases the risk of losing balance. Proper lifting requires a wide, stable base with feet shoulder-width apart. C. "Tighten abdominal muscles to improve balance.": Engaging the core stabilizes the spine, maintains proper posture, and helps prevent back injuries during lifting. This is an important ergonomic technique. D. "Bend at the waist when lifting objects from the floor.": Bending at the waist places excessive strain on the lower back. Proper lifting technique involves bending at the knees and hips while keeping the back straight.
