I am in the 3rd semester of my RN program. I just woke up in a cold sweat realizing I have made a Med error during clinical. I know the RN that I was working with caught it when she was giving the 1300 meds(but that still is no excuse).I left the floor at 1300 for post conference. It was heparin drip needing to be changed at 1145, but I guess I was confused, because there was still so much iv fluid still in the bag. I probably should have asked, but that is hindsight 22. I just read the drug book and heparin that is diluted in ns is only stable for 24 hours. I feel horrible knowing this and being a student I what shoud I do? Should I call my instructor or just wait it out? Help!
