Study Notes

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.
