Question

which of the following tips can help you reduce your chance of repetitive strain injury? (select four answers.)
□ position the computer screen so it is above eye level.
□ keep the mouse as far away from the keyboard as possible.
□ work for as long as possible in one position without breaks.
□ adjust your chair so your feet rest on the floor.
□ alternate between positioning your computer screen on one side and then the other.
□ reduce glare from lights.
□ rest your elbows close to your body.
□ keep frequently used objects nearby.

Explanation:

To reduce repetitive strain injury, we analyze each option:

• "Position the computer screen so it is above eye level" is incorrect as the screen should be at or slightly below eye level.
• "Keep the mouse as far away from the keyboard as possible" is incorrect as the mouse should be near the keyboard for easy access.
• "Work for as long as possible in one position without breaks" is incorrect as taking breaks is essential.
• "Adjust your chair so your feet rest on the floor" is correct as it promotes good posture.
• "Alternate between positioning your computer screen on one side and then the other" is correct as it reduces strain from fixed positioning.
• "Reduce glare from lights" is correct as glare can cause eye strain and poor posture adjustments.
• "Rest your elbows close to your body" is correct as it maintains a neutral arm position.
• "Keep frequently used objects nearby" is correct as it reduces reaching and strain. Wait, no, the question asks to select four. Wait, let's re - evaluate:

Correct tips for reducing repetitive strain injury:

1. Adjust your chair so your feet rest on the floor: Proper chair adjustment supports good posture.
2. Reduce glare from lights: Reduces eye strain which can lead to poor posture and strain.
3. Rest your elbows close to your body: Maintains a neutral arm position, reducing shoulder and arm strain.
4. Keep frequently used objects nearby: Reduces the need to reach, which can cause strain.

Wait, earlier mistake. Let's re - check each option:

• Position the computer screen above eye level: Incorrect (should be at or slightly below).
• Keep mouse far from keyboard: Incorrect (should be near for easy access).
• Work long without breaks: Incorrect (breaks are necessary).
• Adjust chair for feet on floor: Correct.
• Alternate screen position: Not a standard tip for RSI (RSI is more about body posture and repetitive movements, not screen side - to - side). So this is incorrect.
• Reduce glare: Correct (eye strain can lead to postural issues and RSI).
• Rest elbows close to body: Correct (good ergonomic posture).
• Keep frequently used objects nearby: Correct (reduces reaching, a repetitive strain risk).

So the four correct ones are: Adjust your chair so your feet rest on the floor, Reduce glare from lights, Rest your elbows close to your body, Keep frequently used objects nearby. Wait, but let's confirm ergonomic principles:

Ergonomic tips to prevent RSI:

• Maintain proper posture: Adjust chair so feet are on the floor (supports spine alignment).
• Reduce eye strain: Reduce glare (so you don't strain your eyes and body to see).
• Arm and elbow position: Rest elbows close to body (reduces shoulder and arm fatigue).
• Arrange workspace: Keep frequently used items nearby (reduces repetitive reaching).

The other options:

• Screen above eye level: Causes neck strain (incorrect).
• Mouse far from keyboard: Causes arm to reach, increasing strain (incorrect).
• Work without breaks: Increases fatigue and strain (incorrect).
• Alternate screen side: Not a typical RSI prevention tip (incorrect).

So the four correct options are:

• Adjust your chair so your feet rest on the floor.
• Reduce glare from lights.
• Rest your elbows close to your body.
• Keep frequently used objects nearby.

Answer:

• Adjust your chair so your feet rest on the floor.
• Reduce glare from lights.
• Rest your elbows close to your body.
• Keep frequently used objects nearby.
