Can someone explain to me what this is?

I recently heard someone(not on here) talking about how they were in a dual BSN/MSN program where they wouldn't get their BSN-RN and wouldn't graduate from their BSN till the end.....well it sort of confused me and I was just curious if someone could explain this too me

I also heard them talk about then going on to be a NP, but I thought they were trying to make it that you had to have some clinical experience 1st. Can you go all the way to a NP without ever being a RN

TIA!!
