单选题 The nurse is caring for a client who complains of lower back pain. Which instructions should the nurse give to this client to prevent back injury?
A. Bend over the object you're lifting.
B. Narrow the stance when lifting.
C. Push or puI1 an object using your arms.
D. Stand close to the object you're lifting.

【正确答案】 D

【答案解析】Standing close to an object being lifted moves the body's center of gravity closer to the object, allowing the legs, rather than the back, to bear the weight. No one should bend over an object when lifting; instead, the back should be straight, and bending should be at the hips and knees. When lifting, spreading the legs apart widens the base of support and lowers the center of gravity, providing better balance. Pushing or pulling an object using the weight of the body, rather than the arms or back, prevents back strain. Using a larger number of muscle groups distributes the workload.
