In that case, we need to arm and train nurses. Also, we need to require that they are well versed in constitutional law as well as state and local laws.  Basically, in addition to all of the work they need to do in order to become nurses, we need them to be constitutional scholars, lawyers, and police.  It shouldn't be a problem as nurses have so much time on their hands...

Sorry to be snide but a nurse is not a body guard. She cannot force an armed and presumably trained sheriff to leave the room or the hospital if he doesn't agree to leave. She stood up for her patient, made clear her position on the blood draw but past that she is not required to risk life and limb for her understanding of constitutional law.
