When keying on a computer, the operator should do which of the following:
- A.
Keep wrists straight while keying
- B.
Have the keyboard and mouse just out of reach
- C.
Make the shoulders and upper arms stiff
- D.

Ergonomics issues often occur in the office environment.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Ergonomics issues often occur in the office environment because office workers typically spend long hours sitting at desks, using computers, and performing repetitive tasks. These activities can lead to musculoskeletal disorders, such as back pain, neck strain, and carpal tunnel syndrome. To prevent these issues, it is important to have ergonomically designed workstations and promote proper posture and movement throughout the workday.Rate this question:

Which of the following is a risk factor associated with ergonomics?
- A.
Sufficient recovery time between computer tasks
- B.
Awkward posture
- C.
Changing tasks often so that the employee doesn't perform the same motion every few seconds or on a continuos basis
Correct Answer
B. Awkward postureExplanation
Awkward posture is a risk factor associated with ergonomics because it can lead to musculoskeletal disorders and injuries. Maintaining an awkward posture for an extended period of time puts strain on the muscles, tendons, and ligaments, increasing the risk of discomfort and injury.

Computer operators should not operate the computer with wrists bent backwards (extension) or forward (flexion.)
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Operating a computer with wrists bent backwards or forwards can lead to discomfort and potential injury. This is because these positions put strain on the tendons, muscles, and nerves in the wrists and can lead to conditions like carpal tunnel syndrome. It is important for computer operators to maintain a neutral wrist position, with the wrists aligned with the forearms, to minimize the risk of injury and promote ergonomic health. Therefore, the statement that computer operators should not operate the computer with wrists bent backwards or forwards is true.Rate this question:

Desk chairs used by computer operators should have good lumbar support
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Desk chairs used by computer operators should have good lumbar support because sitting for long periods of time can put strain on the lower back.

Sitting in a chair that maintains the back in an upright position, lessens fatigue and decreases the amount of work the back muscles must do.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Sitting in a chair that maintains the back in an upright position can help reduce fatigue and minimize the strain on the back muscles. By providing proper support to the spine, this type of chair promotes good posture and prevents slouching, which can lead to muscle fatigue and discomfort. With less work required from the back muscles, individuals may experience decreased fatigue and increased comfort while sitting for extended periods of time. Therefore, the statement is true.Rate this question:
-
- 14.
A chair which is curved and has no lumbar support decreases slouching and other postures that put pressure on the spine.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement in the question suggests that a chair without lumbar support decreases slouching and other postures that put pressure on the spine. However, this is incorrect. A chair without lumbar support may actually increase the likelihood of slouching and poor posture, as it does not provide adequate support to the lower back. Lumbar support helps maintain the natural curve of the spine and promotes proper alignment, reducing the risk of strain and discomfort. Therefore, the correct answer is false.Rate this question:
