Ergonomics Quiz
Questions: 16 · 10 minutes
1. What is the most appropriate way to use a sit-stand workstation?
Stand for every task, even after discomfort begins
Alternate positions based on comfort and task needs rather than staying fixed
Set the standing surface at seated elbow height for all users
Use it mainly to avoid taking walking or recovery breaks
2. While using a mouse, you notice your wrist bends outward and your shoulder reaches forward. Which change is most appropriate?
Increase pointer speed so every movement is larger and more deliberate
Rest the wrist firmly on the desk while moving the mouse from the wrist
Place the mouse beyond the keyboard to create more desk space
Move the mouse closer and keep the wrist relatively neutral
3. Which combination is most associated with increased ergonomic strain during repetitive work?
Task variety, adjustable tools, moderate effort, and recovery time
Neutral joints, low force, short duration, and self-paced work
Occasional reaching, brief standing, visual focus, and scheduled breaks
High repetition, forceful effort, awkward posture, and limited recovery
4. A storeroom is being reorganized. Where should frequently handled, moderately heavy items generally be placed?
Within an easy reach zone, roughly between knee and shoulder height
Above shoulder level to keep the main shelves clear
At the far back of deep shelves to preserve aisle space
On the floor to prevent them from falling
5. Someone uses a laptop at a desk for several hours each day. Which setup most directly improves both screen and input-device positioning?
Place the laptop flat on the desk and lean forward when reading
Raise the screen and use a separate keyboard and pointing device
Raise the laptop and continue typing on its built-in keyboard
Move the laptop farther away while increasing screen brightness
6. Which keyboard position usually places the upper body in a more comfortable working posture?
Close enough for relaxed shoulders and elbows near the sides
Near the far edge of the desk so the forearms stay unsupported
High enough that the wrists bend downward while typing
Angled to one side so the dominant hand has more room
7. Which statement best reflects current ergonomic thinking about posture?
Sitting upright without back support is always the least demanding posture
Regularly changing among comfortable positions is generally better than holding one position
A neutral posture eliminates the need to move or take breaks
Standing should replace sitting for the entire workday
8. During frequent calls, a worker holds the phone between the shoulder and ear while typing. Which change most directly reduces the awkward neck posture?
Use a headset, speaker function, or another hands-free option
Raise the chair so the shoulder reaches the phone more easily
Switch the phone between shoulders every few minutes
Move the keyboard farther away to make room for the elbow
9. What is the main aim of ergonomics?
To maximize work speed by standardizing every movement
To teach people one ideal posture that should be maintained all day
To fit tasks, tools, and environments to people’s capabilities and needs
To replace breaks with more supportive equipment
10. Why can brief movement or recovery breaks help during sustained computer work?
They strengthen the same muscles used for prolonged sitting
They permanently offset any workstation mismatch
They make neutral positioning unnecessary for the rest of the day
They interrupt static loading and allow the eyes and body to vary their demands
11. Sunlight from a window creates reflections on a computer screen. Which change is usually most effective?
Reposition the screen roughly perpendicular to the window and manage the light source
Turn the screen directly toward the window and increase brightness
Lower the screen until reflections fall below the user’s line of sight
Move closer to the screen so the reflections occupy less of the visual field
12. You need to move an unfamiliar box from the floor. What should you do first?
Lift quickly before the muscles have time to tense
Keep the legs straight so the back controls the movement
Check its weight and route, then use help or an aid if needed
Hold the box away from the body to see the walking path
13. Which monitor arrangement generally helps reduce sustained neck turning and awkward viewing angles?
Off to one side, with the screen tilted sharply upward
Directly ahead, with the entire screen above eye level
Directly ahead, at a comfortable distance, with the top around eye level or slightly below
As close as possible, with the bottom edge level with the eyes
14. A seated worker’s chair is adjusted for the desk, but their feet no longer rest comfortably on the floor. What is the best response?
Lower the chair even if this forces the shoulders upward while typing
Use a stable footrest that supports the feet without crowding the legs
Keep the feet suspended so the thighs remain horizontal
Slide forward until only the toes touch the floor
15. A team repeatedly carries heavy supplies along the same route. Which redesign best follows the hierarchy of ergonomic controls?
Post reminders telling everyone to lift with perfect technique
Rotate workers more often while leaving the load and route unchanged
Require lifting belts before reviewing the task itself
Reduce the load or use suitable mechanical handling equipment
16. A worker develops recurring tingling and discomfort during a repetitive task. What is the most appropriate response?
Continue unchanged until the symptoms remain after work
Work faster so the repetitive task ends sooner
Report or address it early and review the task, equipment, workload, and recovery time
Immobilize the affected area while completing the same task
