Unfortunately, it sounds like you are stressed out, and that condition does not bode well. Please take a few deep breaths. The DON is reacting to your errors, like she has to. Your errors are not indicative of a bad nurse, maybe a new one, but not a bad one. Please have a nice New Year's Eve and relax if you can. Get your mind off this for awhile, then go back to work and work as hard, and detail orientated as you can. You didn't kill anyone, and probably haven't hurt anyone, and it sounds like you reported the two narc doses yourself. I don't mean for you to take the written warning lightly, but I don't want you to be so nervous, and anxiety pressed, that you make another error.
