Preceptorship on renal floor

I'm a fourth-semester ADN student and will be starting my preceptorship (120 hours) in a couple of weeks. I've been assigned to the renal floor. Would love any advice or tips from renal nurses as to what I need to be prepared for that is specific to this floor. Also would like to hear some advice on working the night shift. I will be working weekends 7p-7a and have never worked at night in my life!
