How are you doing both programs at the same time? It is impossible. Do you mean you are working on prereqs that will transfer to both? For my BSN I was either at school or clinical 4-5 days a week. To complete a BSN in 4 years you are usually taking the maximum allowed credit hours each semester so there really is not room for extra classes let alone paramedic classes.
I would focus on one thing at a time. There is already a fairly high attrition rate for BSN programs, I would not risk it.
