In fairness, a number of people on the other thread suggested people wait to see how this plays out. They thought the nurse go short shrift when it came to fully explaining her position.
For the record, I railed on her.
I am a nurse. There is no explanation she could give other than the girl requested the test that passes muster. The girls life was in no imminent danger, she signed no consent for treatment, the nurse did not have a doctor's order for the procedure, the girls' family was not notified, I can go on and on. She should lose her license and be fined $25,000 for violating HIPPA laws.
