What term means the way the parts of the body work together when a person moves?

• A. Body mechanics
• B. Bone loss
• C. Body temperature
• D. Bowel program

Answer: (A)

Understanding how the body parts work together during movement is about body mechanics. It covers how the muscles, bones, joints, and nerves coordinate to move efficiently and safely, focusing on posture, alignment, balance, and using the strongest parts of the body to perform tasks. In CNA practice, good body mechanics protect you and the resident by reducing strain and injury during transfers, turning, and lifting. This means keeping a neutral spine, standing with feet shoulder-width apart, bending at the hips and knees, holding objects close to your body, and avoiding twisting or sudden jerks. If a task requires more effort or risk, use assistive devices or ask for help. Other terms like bone loss, body temperature, or bowel program describe different topics—bone loss concerns density, body temperature relates to thermoregulation, and bowel program relates to bowel care—not to how movement is coordinated.
