Wisconsin CNA State Exam Vocabulary Practice

What is body mechanics?

1. Groups of organs that perform specific functions in the human body.

2. The normal temperature of the human body.

3. The way the parts of the body work together when a person moves.

4. Tissue damage that results from various factors.

The correct answer is: The way the parts of the body work together when a person moves.

Body mechanics refers to the way in which the various parts of the body work together to facilitate movement and maintain balance, particularly during physical activities. It encompasses the principles of proper body positioning and movement techniques that help improve bodily efficiency and prevent injury, especially in contexts like healthcare where nurses and nursing assistants frequently lift, transfer, or assist patients. Understanding body mechanics is crucial for CNAs as it allows them to perform their tasks more safely and with less strain on their own bodies. By effectively using their bodies in a coordinated manner—incorporating the legs, back, and arms—they can minimize the risk of injury to both themselves and their patients. In contrast to the other options, which do not accurately capture the essence of body mechanics: the description of organs performing specific functions pertains to anatomy, body temperature relates to physiology, and tissue damage involves pathology rather than the mechanics of movement.
