Hello, I am a nurse of 3 years with no prior medication errors. I recently started working at a new hospital and thought things were going well. The other day I received an email from my floor manger asking if I knew anything about a med error that happened. I took care of a patient who was in the hospital for some respiratory issues and also had diabetes. She had normal saline ordered and running. Apparently when night shift came on they found D5 1/2 NS infusing. I remember while I was on the phone getting report for a new patient the nursing assistant came to me and said Mr. smiths IVFs are empty. I turned to the nurse next to me and asked her kindly if she could hang a new bag. With all the hustle and bustle I forget to check her work. I am unsure If this is the result of her error or if I mistakingly hung it at some point during the day. we were also having a computer troubles that day. I understand even if the other nurse did hang it, I am mostly responsible. I told my nurse manager I am unsure of what happened. I am really nervous. I have not heard back about this incidence and its been over a week. She never said anything penalizing to me and figured I would hear an update from her. What should I do? Am I over worrying on something I really did not know what happened?
