Beginning an RD Education

There are also "accelerated" BSN degree programs that accept individuals with a prior bachelor's degree if they meet the admissions requirements & pre-requisites.

you don't get an rn from a school. "rn" means "registered nurse," as in "registered with a state board of nursing licensure." you are entitled to take the licensing exam to obtain rn licensure after you graduate from an accredited school of nursing.

an associate's degree in nursing takes more time than an associate's degree in, say, english because there are prerequisites in health-related subjects like anatomy, physiology, chemistry, and such; some may require your being certified as a nursing assistant (at your own expense) before you start so they don't have to spend so much of your very limited school clinical time mastering basic clinical psychomotor skills, and also to weed out the folks who always wanted to be nurses but are shocked when they come up against the reality of dealing with actual messy human bodies and can't hack it. that makes room in the entering nursing classes for people who really want to be there and already know they can.

you might be able to take an accelerated bachelor's-in-anything-to-bsn program using some of your previous credits for electives. you might also be able to find a bachelor's in-anything-to-msn program that appeals to you. you seriously need to contact several different schools and find out what they require and what they offer, and see if they accept what you bring to the table before you can make a decision on how to proceed.
