Student with MSBP

Okay, I'm in my 3rd semester of the RN program in my school and I'm very concerned about a certain other student (whom I know previously) who is also in the program this year. To put it simply, she has Munchhausen by Proxy (actual diagnosis.) She has a history of showing up to her children's schools and insisting that they be administered medications for illnesses that they didn't have. Her kids were always sick when they stayed with her and got better when they were back with their dad. She no longer has unsupervised access to them.

She has absolutely no business being an RN! I've ignored it for the first 7 weeks of the semester, but my conscience is telling me this is not something to ignore. I'm considering talking to the program director without mentioning any names (unless asked, of course). Am I off base here? What would you do?
