This one was a heparin drip, and I misread the order, which said that if the factor Xa is above ___, turn off the heparin for 60 minutes and then restart the heparin but decrease the dose by 300 units/hour. Well, I for some reason I read the order as "turn off the heparin for 3 hours and then restart the heparin but decrease the dose by 300 units." So at 1400 I turned off the heparin, then at 1500 I told the oncoming RN that the heparin should be restarted at 1700 & decreased by 300. The evening RN asked if there were written orders for her to check, and I said that yes, the MD orders were there to read, in case she wanted to double check what I'd reported (that's certainly what I would do). At 1530, after finishing all my reports and charting, I clocked out. At 1600, while I'm on the train home, I get a call on my cell from the previous RN asking where I got the "3 hours" stuff. I did not have access to my work computer at that point, so I said that I THOUGHT the order had read "turn off for 3 hours" - had I misread it? The previous RN just shouted, "WRONG," then said she'd restart the heparin now.
I guess my question is, how much trouble am I in? I'm pretty sure the evening RN will report me, write an incident report, etc because she sounded pretty indignant on the phone. Sometimes I hate being a nurse, but I try and I try and I try to do everything perfectly.
