I am a new grad and this will be my first week off orientation on a busy cardiology step down unit at a major teaching hospital. Any words of advice for me? I feel ok w/ the routine day to day stuff, but have never really had an unstable pt and this worries me! I know I am never truly "on my own", but can't help being nervous w/out my preceptor. Is there anything you wish you knew starting out, that you had to learn the hard way? Any advice is appreciated!
