A nurse is collecting data from a client at a follow-up clinic visit for acute low back pain. A goal for this client is to use proper body mechanics at all times. Which of the following findings indicates that the client is meeting this goal?
Explanation & Rationale
Choice A rationale Shifting weight to the heels when moving an object to the side is an incorrect application of body mechanics. Proper technique involves pivoting the entire body as a single unit rather than twisting the lumbar spine. Putting weight on the heels can lead to instability and loss of balance during the transition. The client should instead focus on a broad base of support and smooth weight shifts to avoid straining the lower back muscles. Choice B rationale Standing with the feet close together during a lift significantly narrows the base of support. This reduces the stability of the center of gravity and increases the risk of falling or causing a musculoskeletal injury to the back. For safe lifting, the feet should be shoulder-width apart to provide a stable foundation. This positioning allows the larger leg muscles, such as the gluteals and quadriceps, to bear the load rather than the vulnerable spinal discs. Choice C rationale Facing the direction of movement when sliding or moving an object is a fundamental principle of proper body mechanics. This alignment prevents rotational or twisting forces on the spine, which are primary causes of acute and chronic back injuries. By keeping the shoulders and hips square to the object, the client maintains the natural curvature of the spine. This finding indicates the client successfully understands how to protect the back while performing activities of daily living. Choice D rationale Moving the front foot backward when pushing an object is counterproductive to generating force and maintaining balance. To push effectively, a person should move the rear foot forward or lean into the object using their body weight. This stance ensures that the force is generated by the legs and transferred through the core. Reversing the foot movement compromises the stability of the posture and places unnecessary stress on the lower back and shoulder joints.
