Answer: D - The nurse aide tightens the abdominal and gluteal muscles before lifting or moving a client. Other correct principles of body mechanics are:
-If the client is able, asking him or her to participate in the changing or transferring of positions is necessary to lessen your load, thus preventing muscle strain on your part.
-Push, slide, or pull whenever you can, rather than lifting. Pushing is better than pulling.
-A good base of support is needed for balance. Stand with your feet apart for a wider base of support, and bend your knees when transferring clients.
