Question

the nurse teaches correct body mechanics to the unlicensed assistive personnel (uap). which instruction by the nurse is most appropriate?

1. \twist at the waist when moving clients.\
2. \hold heavy objects away from your body.\
3. \bend at the knees when lifting objects.\
4. \avoid using the large muscles of your legs.\

Explanation:

• Option 1: Twisting at the waist when moving clients increases the risk of back injury. The spine should be kept in alignment.
• Option 2: Holding heavy objects away from the body increases the torque on the back muscles and spine, increasing the risk of injury. Objects should be held close to the body.
• Option 3: Bending at the knees when lifting uses the stronger leg muscles (quadriceps, hamstrings) instead of relying on the weaker back muscles. This helps to maintain the natural curvature of the spine and reduces the risk of injury.
• Option 4: The large muscles of the legs (e.g., quadriceps, gluteus maximus) are stronger than the back muscles. They should be used for lifting to reduce the strain on the back.

Answer:

1. "Bend at the knees when lifting objects."
