Question 1

Which of the following is classified as a Work-Related Musculoskeletal Disorder (WMSD)?

Accepted Answer

Carpal tunnel syndrome

Answer

Carpal tunnel syndrome involves compression of the median nerve in the wrist and is a classic WMSD linked to repetitive hand and wrist tasks.

Question 2

The primary ergonomic risk factor associated with the development of lateral epicondylitis (tennis elbow) is:

Accepted Answer

Repetitive forceful gripping and forearm rotation

Answer

Lateral epicondylitis results from repeated strain on the extensor tendons at the elbow, commonly caused by forceful gripping and forearm rotation at work.

Question 3

Which NIOSH equation variable accounts for the horizontal distance between the worker's hands and the midpoint of the ankles during a lift?

Accepted Answer

Horizontal multiplier (HM)

Answer

The horizontal multiplier (HM) decreases the recommended weight limit as horizontal distance increases, reflecting increased biomechanical stress.

Question 4

De Quervain's tenosynovitis is inflammation of the tendons of which anatomical region?

Accepted Answer

Thumb side of the wrist (radial styloid)

Answer

De Quervain's tenosynovitis affects the abductor pollicis longus and extensor pollicis brevis tendons at the radial side of the wrist and is linked to repetitive pinching and radial/ulnar deviation.

Question 5

Which ergonomic risk factor is described by the term 'contact stress'?

Accepted Answer

Hard surfaces pressing against soft tissues of the body

Answer

Contact stress occurs when body parts (wrists, forearms, knees) rest against hard or sharp edges, compressing soft tissues and restricting blood flow.
