Tied in the middle

I’m having a problem, my major in college in biology but I want to become a nurse. I was talking with my god mom who gave me the idea to become a PA(Physician Assistant). I was wondering should I change my major to pre med or keep it biology? When I come out of college with a degree in biology or pre med is it going to help me with any of the two careers or is it going to be like I’m starting over again?

One becomes a PA through a master’s degree in it (http://www.bls.gov/ooh/healthcare/physician-assistants.htm), so a biology major is appropriate for that. But a degree in biology will slow down the process of becoming a nurse.
