Coffee will be your best friend for the remainder of your nursing career.
Read through your text books, and remember the conversion charts...MG, ML, CC
Try to remember the most critical values amylase levels, PH levels, T3-T4, etc.
Nursing becomes your life, not just a job. You will find yourself dreaming about nursing, gaining new friends who so happen to be nurses. As I look around now, all of the friends I had my first go around in college are no longer as close.
Once you get to your clinical sites, turn off your cell phones & pay attention. Stay close to everyone in the unit, even the unit clerks. You can learn valuable lessons from the Unit clerks, they've typically been there longer than most nurses.
Remember, invest as much time, patience, and if possible, money into your new profession. This will pay off in the long run. The job market may be tough, but great help is hard to pass by!
