Everyone make errors...so the 3 strikes & you're out deal is stupid...it will cause people to lie...and possibly harm patients more... That said, there may be something wrong with the med system that promotes errors...there should be many safe checks to prevent this... ...and it is important for nurses to KNOW each drug they are giving...I write down anything I am unsure of, check it out before I give it, then when I am home research it more extensively, so that I am informed...it's worked for me for many years...good luck
