4.
What are common ergonomic risk factors?
Correct Answer
E. All of the above
Explanation
The correct answer is "All of the above" because all the mentioned factors (awkward body postures, excessive repetition, excessive force, and contact stress) are common ergonomic risk factors. Awkward body postures refer to positions that strain the body, excessive repetition refers to repetitive movements that can cause strain or injury, excessive force refers to using excessive force while performing tasks, and contact stress refers to pressure or compression on body parts. All these factors can contribute to ergonomic risks and potential injuries or discomfort in the workplace.

How far away from your screen should you at least be?
Correct Answer
A. 20-26 inches
Explanation
You should be at least 20-26 inches away from your screen to ensure proper viewing distance. This distance is recommended to reduce eye strain and maintain good posture while using electronic devices. Being too close to the screen can cause eye fatigue and discomfort, while being too far away may result in difficulty reading or seeing small details.
7.
Your face should be parallel to the screen.
Correct Answer
A. True
Explanation
To ensure optimal visibility and clarity during a video call or when using a screen, it is important for your face to be parallel to the screen. This positioning allows the camera to capture your face directly, reducing any distortion or obstructions that may occur if your face is at an angle. Additionally, having your face parallel to the screen helps to maintain eye contact with the person you are communicating with, creating a more engaging and effective interaction.

The brightness of your monitor should be slightly dimmer than the room lighting.
Correct Answer
B. False
Explanation
The statement suggests that the brightness of the monitor should be slightly dimmer than the room lighting, which is incorrect. The brightness of the monitor should be adjusted according to personal preference and comfort, not based on the room lighting. People may prefer different levels of brightness on their monitors, depending on factors such as eye strain, ambient lighting conditions, and personal preference. Therefore, the statement is false.
9.
The refresh rate on your monitor should be at least
Correct Answer
C. 70hz
Explanation
A refresh rate of at least 70Hz is recommended for your monitor. This is because a higher refresh rate allows for smoother and more fluid motion on the screen, reducing motion blur and improving the overall visual experience. A refresh rate lower than 70Hz may result in noticeable flickering and less responsive visuals, especially during fast-paced activities such as gaming or watching videos.
10.
What are some things you can do to prevent posture stress?
Correct Answer
D. All of the above
Explanation
The correct answer is "All of the above" because adjusting the keyboard height helps to maintain a neutral wrist position, avoiding unnatural angles that can cause stress. Sitting up straight also promotes good posture and reduces stress on the spine. Therefore, implementing all of these measures can effectively prevent posture stress.
