It is best to position your computer monitor so that:

You have to lean forward to clearly see the text

You can clearly read the text without leaning forward, twisting your neck, or looking too far upwards

Wherever your lap happens to be

Approximately at your elbow height

The correct answer is approximately at your elbow height. This is because when the keyboard is positioned at elbow height, it allows for a neutral and comfortable position for the wrists, reducing the risk of strain or injury. Keeping the wrists straight is important for maintaining proper alignment and preventing discomfort or repetitive strain injuries. Therefore, positioning the keyboard at elbow height is the most ergonomic and recommended option.

5. The chair should be adjusted to at least provide support to what part of the back?

The shoulder blades.

The lumbar region.

The middle of the back.

The lumbar region is the correct answer because it refers to the lower part of the back, specifically the area between the ribs and the pelvis. Adjusting the chair to provide support to the lumbar region is important for maintaining proper posture and reducing strain on the lower back. This support helps to align the spine in its natural curve and prevents slouching or hunching forward, which can lead to discomfort and potential back problems.
