Texas Certified Nursing Assistant (CNA)

Which statement about body mechanics is accurate for nursing assistants?

1. They should always bend at the waist

2. They should lift heavy objects without assistance

3. They should use their legs to lift, not their back

4. They should avoid using proper posture

The correct answer is: They should use their legs to lift, not their back

The statement emphasizing the use of legs for lifting is correct because it highlights an essential principle of body mechanics that helps prevent injury. When nursing assistants utilize their leg muscles for lifting rather than their back, they reduce the risk of strain and injury to the lower back, which is particularly vulnerable during lifting tasks. Proper body mechanics, including maintaining a straight back and bending at the knees while keeping the object close to the body, allows nursing assistants to safely handle patients and equipment. Using legs for lifting distributes weight more evenly and engages larger muscle groups, which are better equipped for the task, thereby promoting safety and efficiency in movement. This approach not only enhances the caregiver's physical wellbeing but also ensures that they can provide care effectively over an extended period. Proper training in body mechanics is critical in the nursing field to support both the healthcare worker and the patients they care for.
