Well written. I'll offer two more recommendations that apply in all nursing units but particularly critical care.
1. Remember that you are part of a team; don't hesitate to ask for help because your patient can sink in seconds. Also, don't hesitate to offer help.
2. Remember that while your patient is central to your focus, he's not alone (hopefully). Include his loved ones in your care because they need your attention, too.
Good luck,
