I'm sorry Violet, but I'd warn strictly against Theistic Evolution. Throwing out the Book of Genesis (by saying that it is figurative) would allow for Evolution if the events in Genesis were not referenced throughout the rest of the Bible. If Adam and Eve figuratively sinned, we would not of needed Jesus would we?
As far as either "going along to pass" or "standing up and not passing"...well it's a hard choice. However, I'd strongly caution your relative about compromising their beliefs. If you can't stand up for your beliefs when there's little to lose (class pressure, loss of favor, even not getting the degree) then how will they stand up when it's life or death? Tell your relative to use this as a stepping stone.
Also the obvious answer is to seek God's will. God would not direct your relative to become a nurse if they would have to compromise their beliefs or lose the ability to have the job. If it is God's will for them to be a nurse, pray that God will show them the right steps to take
