The priority information for the nurse to include is to adjust their chair so that their elbows are at desk height. This is important because it promotes proper ergonomics and helps prevent musculoskeletal disorders associated with prolonged computer use.

Taking a walk after work, pointing and flexing toes periodically, and having visual acuity assessed regularly are all good practices, but they do not directly address the issue of sitting for long periods and using a computer.
