Body Mechanics and Patient Positioning
ACTUAL QUESTIONS AND CORRECT
ANSWERS
What is the importance of proper body mechanics for nurses during patient care?
CORRECT ANSWERS Proper body mechanics prevent nurse injuries such as back
strains, muscle fatigue, and joint problems. They also ensure safe handling of patients, reducing
the risk of patient falls or injuries. Using correct posture and movement techniques promotes
efficiency during care. Additionally, it contributes to the nurse’s long-term musculoskeletal
health.
Describe the correct posture a nurse should maintain when lifting a patient manually.
CORRECT ANSWERS The nurse should keep their back straight and avoid bending at
the waist. The knees should be bent, and the feet positioned shoulder-width apart for stability.
The nurse should lift with the leg muscles, not the back muscles. Holding the patient close to the
body reduces strain and enhances safety.
Why is it important to adjust bed height before repositioning a patient?
CORRECT ANSWERS Adjusting the bed height prevents unnecessary stretching or
bending of the nurse’s back. It allows the nurse to maintain proper body mechanics while
providing care. A comfortable working height minimizes fatigue and the risk of injury. It also
ensures the patient can be moved safely and comfortably.
What is the role of a gait belt in patient transfers?
CORRECT ANSWERS A gait belt provides the nurse with a secure grip to assist patients
safely during transfers. It helps stabilize the patient and prevents falls. The belt allows controlled
movements while reducing strain on the nurse. It is particularly useful for weak, elderly, or
unsteady patients.
Explain the principle of “base of support” in body mechanics.
, CORRECT ANSWERS The base of support refers to the area beneath a person that
provides stability. A wider base increases balance and prevents falls during lifting or moving
objects. Nurses should place their feet shoulder-width apart when handling patients. Maintaining
a stable base reduces the risk of musculoskeletal injuries.
How does bending the knees instead of the waist help prevent injuries?
CORRECT ANSWERS Bending the knees allows the legs, rather than the back, to do
most of the lifting. This reduces strain on the spinal muscles and vertebrae. It also promotes
better control during lifting or transferring patients. Using the legs’ stronger muscles helps
maintain proper posture.
What is the correct technique for moving a patient up in bed?
CORRECT ANSWERS The nurse should first adjust the bed to a comfortable height.
Place the patient’s arms across the chest to prevent injury. Use a friction-reducing sheet or draw
sheet if available. Bend the knees, keep the back straight, and use leg muscles to gently slide the
patient upward.
Why is it important to avoid twisting the spine while moving a patient?
CORRECT ANSWERS Twisting the spine can cause back strains or spinal injuries. It
destabilizes the body, increasing the risk of falling or dropping the patient. Nurses should pivot
with their feet instead of twisting their torso. Proper alignment maintains safety for both nurse
and patient.
Describe the “squat lift” technique and when it should be used.
CORRECT ANSWERS The squat lift involves bending the knees while keeping the back
straight to lift objects or patients. The nurse’s feet should be shoulder-width apart, and the object
close to the body. It is used when lifting patients who cannot assist in moving themselves. This
technique reduces back strain and maintains proper body mechanics.
How should a nurse position a patient to prevent pressure ulcers?
