Coumadin. I have a question on a situation I was in and wonder what others would do. Had a patient that was on 3mg of coumadin. Got an order that said start on 2.5mg of coumadin tomorrow. I was told that I should of assumed the Dr. Did not want any coumadin given that night. I do not believe the Pt/INR was critical cause I had no order to give vitamin k. I thought I was following Dr. Orders appropriately but was told by management I made a drug error and got a 3 day suspension. Must go see the administrator Monday AM. What do others think.
