The same thing has happened to me numerous times with the same nurse and not just insulins but medications, treatments ect. I complained and all to no avail except to only have my work scrutinized and that same nurse lie on me. So even though you have the right idea I'm not even sure it pays off anymore. After 12 years in this business it seems that the worse nurse you are the higher up the ladder you go. This nurse was recently named nurse of the year and given a promotion to a nurse managers position. You would think that after all that her behaviour would change, it hasn't and she continues to recieve accolades. At least she is off the floor and can do no harm, however I do wonder when someone is going to realize what a fraud she is.
