I'm of the belief that if you really don't want to go somewhere, you shouldn't apply to it/rank it
I had a classmate from college who was #1 in his class in a top 15 medical school match at his 17th choice in an EXTREMELY competitive field (at a good school, but it was in the middle of nowhere)
for like ONE day he complained, then realized how fortunate he was to a - have matched, b - be at a good institution, regardless of location.
If she really wants, she can try and transfer. But it is honestly a little un-doctory to be this upset if she ranked the place - especially if you consider how they invested a significant amount of time in her to screen/interview/rank her for their program
