Is this a Med Error? I have been kicked from clinical. Help

[nursing?s]

I' am in my last quarter of nursing and I was recently failed for my clinical portion 2 days from graduation. I looked into a MAR to see if a client could have a narcotic. Turns out the client had 10 min befor she could get it. The ten minutes passes and I go into the narc drawer and again double check the last time she had the medication and it was indeed time for her to get it. I signed the narc book and being a student needed a cosigner asked my instructor to cosign. She asked me where the MAR was and I told her it was in the MAR book. She said "so you want me to sign a med without having the order from the MAR? Its not safe!" and sent me home to fail the clinical portion and therefor have to repeat the theory and clinical portion next quarter. I'm fighting it but I wanted to know, has anyone else ever had a nurse/teacher co-sign a narc without the teach/nurse seeing the MAR first? As I thought the narc book only verifies the count I would always just have them cosign and then do my 3checks of the seven rights and administer the medication. Is/was this wrong or have any of you done the same thing? Thanks for your help

Just and update, I wrote the Dean to reverse the decision to kick me out, she denied my request. So now I'm appealing to the VP of my school, hopefully having someone on the outside looking in will help me. I talked to my fellow classmates and other people in the nursing program and this was never a policy that anyone has ever beed trained on and now they are going around to each class telling them about the "old" policy that they are now expected to follow. #ifonlynursingcreditstransfered
