I'm about 10 months away from graduating from nursing school, and ive worked in an emergency room for a couple of years, so i know a thing or two. I dont make mistakes, I dont have room to make mistakes. So last night one of the RN's asked one of our techs to switch this pts iv fluid from potassium to NS and run it in at 800ml/hr. well, he was on his way up to the roof to get a pt coming in from lifeflight and asked me to change the pt in 6's iv pump from 150 to 800/hr. ok- so i ran in there quit while in the middle of doing 50 other things (on a holiday weekend we are swamped with 20 people in the waiting room, rooms and hallways full, and ems coming in with trauma after trauma). i didnt even LOOK at what was hanging. the nurses rarely ever hang K in the ER, it usually waits until they get upstairs for the floor nurses to do. Stupid me. i should have looked and i should have known. Luckily the nurse taking care of that pt. went into the room shortly after and noticed my stupid stupid mistake. I could have easily killed that patient. I am so not worthy to be a nurse now. im afraid that nurse will tell other nurses now and they wont be able to trust me. i am not stupid- and i know that i will make an excellent nurse- but goodness- im feeling pretty worthless right now.
