I'd suspect the basic problem there may have been not so much that the nurse had the wrong attitude - though pretty evidently she had - but that she was following official orders, probably because she was scared she'd lose her job if she broke the rules.

As in so many cases, the real criminals are the people up the top, who make the rules or approve them. And when the shit hits the fan, they walk away unscathed. This stupid nurse might very likely end up carrying the can. Her management won't.
