My largest med error was working in PICU. I Do not recall the exact med, but I pulled it from stock instead of waiting for pharmacy. I checked the dose with two other nurses being that it was an unusual med to give, maybe it was atropine or a code drug. Anyway, when the med came up from pharmacy the concentration was different than I had given. My heart dropped about ten thousand feet straight down. I cried, I called the resident, the cardiologist, and G-D also. The child was fine. His heart rate stayed stable. No negative side effects at all. The other part I remember is that because of the class of the medication there may have been disciplinary actions. It took me a long time and a lot of tears to write up that one. I feel and still do that if a med needs to be checked with another nurse, both should suffer consequences if its wrong. Not just the one actually giving the dose. Just my opinion, no flames please.
