CHT CHT Body Mechanics, Ergonomics & Physical Safety

Question 1

When pushing a wheelchair with a patient, a transporter should maintain which posture?

Accepted Answer

Upright spine, knees slightly bent, hands at a comfortable grip height

Answer

Maintaining an upright spine with slightly bent knees reduces lumbar strain and allows controlled, safe propulsion of the wheelchair.

Question 2

What is the MOST common work-related injury among hospital transporters?

Accepted Answer

Musculoskeletal injuries, particularly to the lower back

Answer

Repetitive lifting, pushing, and repositioning of patients puts transporters at high risk for lower back and musculoskeletal injuries.

Question 3

Before lifting a patient or heavy equipment, a transporter should FIRST:

Accepted Answer

Assess the load, clear the path, and position their body correctly

Answer

Pre-lift assessment of the load and environment, combined with proper body positioning, significantly reduces injury risk.

Question 4

The power zone for lifting is best described as:

Accepted Answer

The zone between mid-thigh and mid-chest where the body can exert the most force safely

Answer

The power zone (mid-thigh to mid-chest) allows the strongest and safest lifting posture by keeping the load close to the body's center of gravity.

Question 5

Which of the following is an example of proper body mechanics when moving a gurney?

Accepted Answer

Pushing the gurney while keeping the back straight and using leg muscles

Answer

Pushing with a straight back and engaging leg muscles distributes force efficiently and reduces spinal stress during gurney transport.
