So as a nurse with little experience I feel I am always learning I graduated in may of 2013 and started my first job in sept . Friday my director called me in stating she was concerned on how I was practicing nursing ...i for one I did not stay with my patient the whole fifteen mins after staring the blood transfusion and in hind sight I relieze that was a safety issue ..another issue is that I didn't give my full insulin coverage because my patient's blood glucose drops in the morning I hadn't realized this was wrong until she brought it to my attention and stated I was practicing medicine ...now I can't sleep I feel sock and just out of energy because I am being investigated by the chief nursing officer and honestly I'm scared will I lose my license ? I honestly didn't mean no harm just doing was I thought was right for my patients ...any advice???
