There have been some incidents like this (maybe not the president, but high profile people) and nurses or other hospital employees have been duped to believe and give out information unwittingly. At times the hospitals have fired the nurses or other staff involved. But humans are humans - they do become star struck and may make mistakes. To me the radio commentators are the ones who should be the ones responsible for all of this. They know better, they only wanted ratings, they totally disregarded any ethical behavior. The Royals, the hospital and most of all the front line staff are the persons who are affected the most by this stunt.
