The next day, she'll feel that her patients aren't respecting her for being special and will lay down the law on them.
This is.... Well, If the nurse is getting supply from her job. Then in theory it should make her really good at her job "most" of the time.
Also in theory, as you've said, if the adoration isn't there from coworkers, or her relatives, or in some weird way that she wants she'll take it out on patients, or her fellow coworkers.
This is very similar to when my N parents took in foster children for supply, and then, when no one was looking, mentally abused them for pleasure. Foster children whom had parents that were the farthest away from being able to care for them. If she begins to feel that she can get away with more, and more without getting exposed, this may happen quite frequently.
If N's can become envious, and jealous of new born children then ...patients. well, yeah. She likely has jealous feelings every time she see's another nurse working with someone. Thus driving her to be "better" than the rest.
