Worst med error - stories?

Brennas dad told a 'worst med error' story under 'interview questions asked....' and I thought I would start a new thread with hopes of some comedy relief and STORYTIME! We love stories, dont we? Well, here is mine.

It was within my first year of ICU (2nd yr as RN) and I was learning how to pull arterial sheaths post cath with the charge nurse. He sent me to sign out some Versed. I got it out of cabinet and decided against my gut to sign it out right then, I will just do it later, got to hurry! The order said to give 2-4mg. This guy BTW was mainly healthy, alert, 40's - 50yo. (Thank God) We go thru the procedure and all went well. Well, about an hour later he is still very sleepy but responding to my questions. So I figure I may as well get his bath over with. Do that. He is STILL sleepy and snoozing. I go to sign out the versed. To MY horror, I took the 5mg ones - Ive only seen the 2mg vials..... I gave that man almost 10mg of Versed!!!!! I go back in to assess him, yes he is breathing ok, no wonder he slept thru that bath! So I call the doc and it was 'just watch him'... so LATER, the 3-11 charge nurse then comes in (versed given around 9-10a) to say hello to him and he smiles brightly and says Good Mornin! He didnt even remember his bath.....
