i would guess that, even if the charges are found to be proved, any punishment meted out to a nurse who is only in this situation because she was saving lives, and given her high public profile, would be seen as utterly draconian.
That's not to say that punishment is not valid - but public perception is everything in these issues, and the image damage caused by seeming to be high-handed and officious will be far greater than any good that may come of the punishment.
For that reason, I think that once all the boxes are ticked, this will be quietly forgotten.
