CNA - Certified Nursing Assistant Body Mechanics 1

Question 1

When raising a resident up in bed, the CNA should first adjust the bed to:

Accepted Answer

A height level with the CNA's waist to reduce back strain

Answer

Raising the bed to waist height allows the CNA to work without bending over, keeping the spine in a neutral position and reducing the risk of back injury.

Question 2

Which foot position provides the widest base of support when performing resident care?

Accepted Answer

One foot slightly in front of the other, shoulder-width apart

Answer

Placing one foot slightly in front of the other at shoulder-width creates a wide, stable base of support, lowering the center of gravity and improving balance during care tasks.

Question 3

When a CNA needs to turn a heavy resident in bed, the safest technique is to:

Accepted Answer

Stand close to the bed and use body weight and leg muscles to roll the resident

Answer

Standing close minimizes the distance weight must travel, and using leg muscles and body weight rather than twisting at the waist protects the CNA's spine from injury.

Question 4

Which is the correct way for a CNA to carry a moderately heavy object across a room?

Accepted Answer

Hold it close to the body near the center of gravity

Answer

Carrying objects close to the center of gravity reduces the load on spinal muscles and decreases the risk of dropping the object or straining the back.

Question 5

A CNA is about to help a resident stand from a chair. Where should the CNA position their own feet before assisting?

Accepted Answer

Shoulder-width apart with knees slightly bent

Answer

A shoulder-width stance with slightly bent knees lowers the center of gravity and engages the leg muscles, allowing the CNA to assist safely without straining the lower back.
