guidelines for a shomer shabbat medical student

I wonder if you could help. I have a student here who just started a midwifery course, and having difficulty avoiding a Shabbat roster.

Would you have a list of guidelines for a shomer shabbat student who is forced to attend on Shabbat, what may and may not be done in different circumstances>

If not, would you know where I could look for such a thing.

many thanks
