take a deep breath amd enjoy 
First little while can be a frightening experience. Take a deep breath and relax. Most importantly learn from your mistakes and you will make them we all have.
The worst thing I ever did and after it was very funny.
We had a lady come to our Med surg florr step down from IcU going home with family the same day.
we helped her pack and helped her dress
Niether of us thought once never mind twice about the monitor she was wearing. So like goo students we wished her luck and sent her home with her family. Of course as soon as she left the building she flat lined on the ICU monitors a STAT was called and everyone was in a panic looking for this lady. we didn't realize she was wearing a telemetry monitor and not a Holter monitor.
We caught S**T big time from our teacher and of course had to hunt down the very expensive piece of equipment. Laughed later but learn a valueable lesson
Get a good Nursing Drug handbook
A little flashlight
A good stethscope
Most importantly get a good nights sleep
Lots of luck and have fun
