Question 1

Carpal tunnel syndrome results from compression of which nerve at the wrist?

Accepted Answer

Median nerve

Answer

Carpal tunnel syndrome involves compression of the median nerve as it passes through the carpal tunnel, causing pain, numbness, and tingling in the hand.

Question 2

The RULA (Rapid Upper Limb Assessment) tool is primarily used to evaluate:

Accepted Answer

Upper extremity postural and force loads

Answer

RULA assesses exposure of the upper limbs, neck, and trunk to ergonomic risk factors including posture, force, and repetition.

Question 3

What is the recommended viewing angle for a computer monitor relative to eye level?

Accepted Answer

Slightly below eye level (10–20 degrees)

Answer

Placing the monitor slightly below eye level (10–20 degrees) allows the neck to maintain a natural, relaxed posture and reduces neck strain.

Question 4

Which engineering control BEST addresses repetitive reaching above shoulder height?

Accepted Answer

Redesigning the workstation to position materials within the worker's power zone

Answer

Engineering controls that reposition materials within the worker's power zone eliminate the hazard at the source rather than managing worker exposure.

Question 5

The 'power zone' for lifting is generally defined as the area:

Accepted Answer

Between knuckle and shoulder height

Answer

The power zone is the area between knuckle and shoulder height, where the body can generate the most force with the least stress on the spine and muscles.
