Angela,
Time management is something you will learn over time. It took me about a year of hospital nursing before I felt like I wasn't running to get things done. Stop, take a breathe, as a previous charge nurse I would rather you slow down and think, perform the duty at hand, and if you get behind or feel rushed ask for help. Regardless of what you may have heard most nurses are willing and able to help out a new grad!
