Texas Certified Nursing Assistant (CNA)

Which statement is true about body mechanics?

1. Body mechanics is unimportant in healthcare

2. Body mechanics helps save energy and prevents injury

3. Body mechanics should only be used when lifting heavy objects

4. Body mechanics is only applicable to trained professionals

The correct answer is: Body mechanics helps save energy and prevents injury

Body mechanics refers to the way in which we move our bodies during daily activities and is essential in healthcare for several reasons. The statement that body mechanics helps save energy and prevents injury is accurate, as the proper use of body mechanics involves maintaining correct posture, using the right muscles for the task at hand, and applying techniques that distribute weight evenly. This practice reduces the strain on muscles and joints, helping healthcare workers perform their duties efficiently while minimizing the risk of injuries, such as sprains or strains, that can occur from improper lifting or awkward movements. In a healthcare environment, where caregivers may frequently lift, transport, or assist patients, understanding and applying proper body mechanics is vital not only for their personal safety but also for the safety of the patients in their care. By utilizing methods that leverage body mechanics—such as bending at the knees instead of the waist, keeping the load close to the body, and maintaining a stable base of support—CNA professionals can enhance their endurance and overall effectiveness while reducing fatigue. This principle is foundational in practice settings, empowering caregivers and ensuring the well-being of both staff and patients.
