After the nurse has taught the patient about correct body mechanics, which patient statement indicates that the teaching has been effective? a. "I will keep my back straight to lift anything higher than my waist."b. "I will begin doing exercises to strengthen the muscles of my back."c. "I can try to sleep with my hips and knees extended to prevent back strain."d. "I can tell my boss that I need to change to a job where I can work at a desk."

b. "I will begin doing exercises to strengthen the muscles of my back."

Explanation:

The teaching has been effective when the patient states "I will begin doing exercises to strengthen the muscles of my back." because by doing so, the muscles that support his back will be strengthened, which will help him to maintain a correct posture and to make fewer efforts when lifting thing. He should not lift things above the level of his elbows even if he keeps him back straight and bends his knees and hips to lift.

The best answer is "B"
