congrats! I remember when a fellow nursing student and i landed the same job and after orientation we found ourselves suddenly in charge. she looked at me and said, "OMG it's just us! everybody else went home and now its just us. They think we are real nurses" I said, "Well I guess we are" and we laughed and laughed and laughed. Was a sudden wake up call for us.
I remember my first IM injection I ever gave on a live human being. She was HIV positive, had Hep B and Hep C, was on TB precautions, and had almost no muscle mass left. My instructor told me, "Don't you dare stick yourself with that needle, I'm warning you". And I didn't.
