I just found this site and had to post. Ive had the worst day today. One of my biggest nightmares has come true! I killed a patient! Obviously, it was an accident but that is of little comfort to me right now. I've sat here and cried for hours -- I had to leave work early. ...Administered a medication they were allergic to it. It was in their file, but I was told to give it and I didn't double check. Clearly, more than myself is involved in this. I'm so worried -- I may lose my license. I'm utterly devastasted this happened. I think this is my last day of nursing... I can't fathom going back as just started 10 months ago. Just had to vent guys.
