I sent a patient out to the hospital believing this person was a Full Code. I then called the On-Call who informed me this patient was a DNR/CMO. I did not find a DNR or CMO form in the chart (neither did the Nurse 's before me). At shift change, another Nurse found a copy of a DNR form in the chart (not in the area where it belonged). My question is this... Is a copy of a DNR from a different facility/hospital valid?? I was always told I had to have the original for it to be valid?
