You can complete the IGETC which is more broad based for UC and CSU campuses with CSU having some additional requirements. Or you can follow their GE course outline for that specific school. In your case you can do the IGETC or do a general education breadth for the specific UC school from your community college. You can look up the specific general education breadth requirements on assist.org and go under general education/breadth after you selected your schools.
I just checked and theres two nursing major types
Nursing-Generic/Prelicensure/B.S. REQUIRES IGETC
Nursing-RN-BS/Postlicensure/B.S. does not require IGETC
Most likely in your case it would be the first option because you would not meet the requirements for the second option so you would have to complete IGETC.
Here are the information from assist.org about the two different majors:
Nursing-Generic/Prelicensure/B.S. :
ASSIST Report: SCC 07-08 UCLA Articulation Agreement by Major
Nursing-RN-BS/Postlicensure/B.S. :
ASSIST Report: SCC 07-08 UCLA Articulation Agreement by Major
I hope this helps you, and good luck
