Take all the advice you can get from your coworkers - especially those who have been around a while. They have figured out all the best ways to do things (just make sure what they are doing is ethical and safe for the patient before you adopt it!) Figure out what each of them do well, and duplicate it. If you take the strengths from each of them, you will have a solid foundation of skills. I am always eager to learn, and I always tell my coworkers what skills I need to work on, and they are always happy to help.
I started on a busy med/surg unit with no experience, and I was really nervous, but working for a year before starting nursing school
has made a huge difference in my performance clinical! Starting as a tech is the best thing you can do!
Good luck, and congrats on the job!
