@Troy991 and for others who have admitted students: there is a group on Facebook called “Northeastern University Parents Group”.
Very helpful parents with tons of experience that can answer your questions regarding programs, housing, co-ops, the pros and cons to all of it.
One of the FB group admins has a nursing student that can answer your specific questions. There a multiple hospitals in the area of course where nursing students do their co-ops, however they also co-op in university research labs and there’s a local (and very robust) EMT program that many do (they get certified as an EMT as part of the program).
