What is Ambulatory Care?

Hi all,

I'm a student going into a clinical placement in ambulatory care, and I need some help understanding what exactly Ambulatory Care is! Could any ACU nurses out there help me? How does the ACU nurses role differ from that of a nurse working on a surgery unit? What is it that you do differently? Is there anything you could tell a student going into this placement to make me less annoying/more helpful? What kinds of tasks/procedures/etc do you let a student assist with.

Any help would be awesome, thanks!
