What is the optimal position for the top of your computer monitor relative to your eyes?
Bottom of the screen at eye level
Top of the screen at or slightly below eye level
Center of the screen 20 degrees above eye level
Top of the screen well above eye level
Placing the top of the monitor at or slightly below eye level helps maintain a neutral neck position and reduces strain. This prevents looking too far up or down, minimizing neck and shoulder discomfort.
What is the recommended viewing distance between your eyes and the computer screen?
50 - 60 inches
2 - 3 inches
Less than 10 inches
About an arm's length (20 - 30 inches)
Maintaining a distance of about an arm's length (20 - 30 inches) helps reduce eye strain and allows for a comfortable field of view. Sitting too close or too far can cause visual fatigue and posture issues.
Which wrist position is considered neutral when typing on a keyboard?
Wrist bent downwards at 45 degrees
Wrist turned inward towards palm
Wrist bent upwards at 30 degrees
Straight wrist, inline with forearm
A straight, neutral wrist position aligns the hand with the forearm, minimizing stress on tendons and reducing the risk of repetitive strain injuries. Deviations can cause pressure on nerves and tendons.
What is the correct angle for your knees when sitting at a workstation?
180 degrees (fully extended)
Less than 45 degrees
120 degrees
Approximately 90 degrees
Sitting with knees bent at about 90 degrees helps maintain good circulation and reduces strain on the lower back. Angles that are too acute or too obtuse can lead to discomfort and circulatory issues.
Which description best defines proper sitting posture at a computer?
Back supported, feet flat on floor, shoulders relaxed
Sitting on edge of chair with knees higher than hips
Leaning forward with feet tucked under chair
Slouched with arms fully extended
Proper sitting posture includes lumbar support, feet flat on the floor, and relaxed shoulders to maintain spinal alignment and reduce muscular tension. Poor posture can lead to back and neck pain.
Which of the following is a common ergonomic risk factor in computer work?
Adjustable chair with lumbar support
Using screens with blue light filters
Typing with a neutral wrist
Repetitive movements without adequate breaks
Repetitive movements without breaks can lead to overuse injuries such as tendonitis and carpal tunnel syndrome. Introducing microbreaks and task variation helps mitigate this risk.
When should you consider using a footrest at your workstation?
When the desk is too low
If you prefer a higher seat height
If your monitor is positioned too low
If your feet do not comfortably reach the floor
A footrest is recommended when chair height must be raised for arm comfort but leaves feet dangling. Proper foot support ensures good circulation and reduces leg strain.
What is the recommended break schedule to reduce musculoskeletal strain during computer use?
A 30-minute break every 5 hours
No breaks if posture is perfect
A 5 - 10 minute break every hour
One long break at the end of the day
Taking a 5 - 10 minute break each hour encourages movement and relieves muscle tension. Regular breaks help prevent fatigue and maintain productivity.
What is the ideal tilt for a standard keyboard to maintain a neutral wrist position?
Flat or slightly negative tilt
Tilted away at 30 degrees
Positive tilt of 15 degrees
Vertical on its side
A flat or slightly negative keyboard tilt keeps wrists straight and reduces bending. Positive tilts can force wrists into extension, increasing strain on tendons.
Where should the mouse be positioned relative to the keyboard?
Above the monitor
On the opposite side of the desk
At the same height and close to the keyboard
On a separate surface lower than the keyboard
Placing the mouse at the same height and within easy reach minimizes arm extension and shoulder strain. This position supports a neutral arm posture.
How should dual monitors be aligned to reduce neck strain?
Offset at different heights
Side by side at the same height and angle
Angled away from the user
One above the other
Aligning dual monitors at the same height and angle allows smooth head movement and avoids twisting the neck. Misalignment can lead to uneven strain on neck muscles.
What adjustment provides proper lumbar support in an office chair?
Raising the armrests
Tilting the seat forward
Lowering the desk height
Adjusting the backrest curve to match the lower spine
Matching the chair's lumbar curve to your lower back maintains the natural spinal lordosis. Proper lumbar support reduces lower back fatigue and pain.
At what height should armrests be positioned for optimal shoulder support?
So forearms rest lightly with shoulders relaxed
Below waist level
Above elbow height forcing shoulders up
Level with the monitor top
Armrests that support forearms at elbow height allow shoulders to relax and reduce muscle tension. Incorrect height can cause shoulder elevation or slouching.
Which strategy best reduces screen glare in a brightly lit office?
Wear sunglasses indoors
Turn off all overhead lights
Increase screen brightness to maximum
Use adjustable blinds or reposition the monitor
Adjustable blinds and monitor repositioning help reduce direct glare while preserving overall lighting. Glare reduction prevents eye strain and headaches.
What is a recommended schedule when using a sit-stand desk?
Change position once in the morning
Sit all day and stand only at lunch
Alternate every 30 minutes between sitting and standing
Stand all day without sitting
Alternating every 30 minutes balances muscle use and reduces fatigue in both standing and sitting postures. Prolonged static postures in either position can cause discomfort.
A user reports shoulder elevation and tension while typing. Which workstation factor is most likely causing this issue?
Armrests set too high forcing shoulders upward
Feet flat on the floor
Keyboard placed directly in front of user
Monitor positioned slightly below eye level
Armrests that are too high push the shoulders into an elevated position, causing muscle tension and discomfort. Proper armrest adjustment allows shoulders to remain relaxed.
Which distance defines the primary reach zone for frequently used items?
More than 40 inches from the body
Within about 20 inches from the body
Directly above shoulder height
20 - 40 inches from the body
The primary reach zone, typically within 20 inches, allows items to be accessed without extending the arms significantly. Keeping frequently used items in this zone minimizes strain and reaches.
Which ergonomic adjustment is most effective to correct forward head posture at a monitor?
Raise the monitor so the top is at eye level
Lower the chair height by 3 inches
Tilt the keyboard away from the user
Push the monitor further back on the desk
Raising the monitor to eye level encourages the head to remain aligned over the spine, reducing forward flexion. Other adjustments have less direct impact on head posture.
What is the best practice for using a laptop to avoid neck and wrist strain?
Use a laptop stand plus external keyboard and mouse
Keep the laptop flat on the desk and type normally
Use built-in keyboard while holding the screen at eye level
Place laptop on your lap to raise screen height
A laptop stand elevates the screen to eye level while an external keyboard and mouse allow neutral wrist and arm positions. This setup reduces neck flexion and wrist deviation.
For keyboard wrist deviation, what maximum angle is recommended to minimize strain?
30 degrees or more
45 degrees toward the ulnar side
Any angle if typing speed is high
Less than or equal to 15 degrees
Keeping wrist deviation within 15 degrees minimizes ulnar or radial deviation stress on tendons and nerves. Excessive deviation increases the risk of repetitive strain injuries.
