It is not an appeal to authority. It is using a definition. It is understanding qualifications. There are authorities that are appropriate. Authority is based on expertise and knowledge. This RN has not been educated in the fields that lead to the ability to diagnose. This the fallacy is accepting his opinion as anything but that. Opinion.
