Nursing Body Mechanics Quiz

Principles of Body Mechanics

• The wider the base of support, the greater the stability of the nurse, according to the principle of a wide base of support.
• Facing the direction of movement prevents abnormal twisting of the spine, emphasizes the principle of direction of movement.

Reducing Risk of Injury

• Reducing the risk of back injury is achieved by bending at the knees and keeping the back straight.

Lifting and Moving

• Pushing or pulling requires less work than lifting.
• Maintaining proper body alignment contributes to body balance and reduces strain on the musculoskeletal structure.
• It is recommended to use mechanical lifts and lift teams when moving heavy patients.

Stability and Friction

• The center of gravity is maintained as long as the line of gravity passes through its base of support.
• The lower the center of gravity, the greater the stability of the nurse, according to the principle of center of gravity.
• Reducing friction between the object and the surface facilitates movement.
• Friction can be reduced when moving a client in bed by using a draw sheet or slide board.

Importance of Body Mechanics

• The primary purpose of learning body mechanics in nursing activities is to prevent injury to the nurse and the client.
• Body balance depends on a wide base of support, low center of gravity, and proper body alignment.
• Maintaining proper body alignment during lifting and moving clients is important to prevent musculoskeletal strain and injury.
• Weight in the context of body mechanics refers to the force exerted on the body by gravity.
• Friction in relation to moving patients in a hospital setting refers to the resistance to motion between two surfaces in contact.
