I don't work in this area but I've shadowed in it. It's probably a great place for you to return after such a long time out of nursing. For each patient, you'll get a set of baseline vitals, do a general assessment, draw any labs ordered, and coordinate any other testing ordered (e.g. X-rays or whatever). Also, you'll start the educational process for the periop experience. It will look and feel a lot like a visit to a doctor's office. Management will want to know that you can be efficient because they will have a maximum amount of time in mind for each patient. It can be repetitive, but that will give you the opportunity to get into a groove. You'll be able to ease your way back into understanding the disease processes, symptoms, and treatments. A good overall picture that you can take into whatever you'd like your next step in nursing to be. Good luck!
