Advice for RN starting RN Refresher Clincal

Dear Nurses,

I am asking for any advice that you might have as to what I might expect as a student nurse taking a RN Refresher in the hospital. (E.g. what can I expect, questions I should ask, how should I present myself) I am starting the first day of clinical portion of my RN refresher at a hospital this week. I am super excited but at the same time nervous. I really want to make a good impression.
About me: I graduated a few years ago and worked as an RN in home care part-time while I was a stay at home nurse. I loved clinical while in nursing school, but never got the opportunity to work in the hospital. I am excited to be spending some time in the hospital as a RN student nurse.

Thank you in advance for any input that you may have
