Practice Quiz On Office Ergonomics For Computer Workstations

The correct answer is approximately at your elbow height. This is because having the keyboard at elbow height allows for proper alignment of the wrists, which helps to prevent strain and discomfort. It ensures that the wrists are not bent upward or downward, promoting a more neutral and ergonomic position. This height also allows for comfortable typing and reduces the risk of developing repetitive strain injuries.

All of the activities mentioned involve repetitive motion. Typing on a keyboard requires the repeated movement of fingers and hands. Moving and clicking the mouse involves repeated hand and finger movements as well. Looking back and forth between the monitor and the source involves repeated eye movements. Therefore, all of the activities mentioned involve repetitive motion.

The lumbar region should be supported by the chair because it is the lower part of the back that curves inward, and providing support to this area helps maintain proper posture and reduces strain on the spine. Supporting the lumbar region also helps prevent lower back pain and discomfort.

An uncomfortable office chair can be considered an ergonomic concern because it can lead to discomfort, pain, and potential health issues for the person sitting in it. Ergonomics is the study of designing and arranging objects and environments to fit the needs and capabilities of the people who use them. In the case of an office chair, it should be adjustable, provide proper support to the back and neck, and promote good posture to prevent musculoskeletal problems. Therefore, an uncomfortable office chair can negatively impact the user's physical well-being and productivity, making it an ergonomic concern.

The best position for a computer monitor is one where you can clearly read the text without any discomfort or strain on your body. Leaning forward, twisting your neck, or looking too far upwards can lead to neck and back pain, as well as eye strain. Seeing overhead lights reflected on the screen can cause glare and make it difficult to read the text. Therefore, the best option is to position the monitor in a way that allows for comfortable reading without any strain or discomfort.
