A nurse is teaching a newly licensed nurse about maintaining correct posture when transferring clients. Which of the following statements should the nurse make?

A. "Tilt your head toward your chest.": Tilting the head down places strain on the neck and upper spine, increasing the risk of musculoskeletal injury. Proper body mechanics require keeping the head aligned with the spine and facing forward. B. "Keep your knees straight.": Keeping the knees locked creates excessive pressure on the back during lifting or transferring clients. Proper posture involves bending the knees slightly to use the leg muscles for support rather than straining the lower back. C. "Keep your back straight.": Maintaining a straight back ensures correct spinal alignment, reduces the risk of back injuries, and promotes safe body mechanics during client transfers. It allows the larger leg muscles to do the lifting instead of the spine. D. "Loosen your abdominal muscles.": Abdominal muscles should be engaged, not loosened, when lifting or transferring. Tightening the core provides stability and helps protect the spine from injury by distributing the workload more evenly.
