HELP! Associates or Bachelors

I need your advice! I am currently interested in going back to school after graduated with a Bachelors in Business three years ago. I want to be an RN but not sure to go get and Associates or get a second Bachelors degree in nursing. I graduated with a 2.85 GPA and am finding that most accelerated bachelors degree programs for nursing require a 3.0. Should I still apply to a bachelors degree program or will an associates degree be good enough? What are the different responsibilites given to Associate degree nurses compared to BSN's? Would i be given the same opportunities with an associates degree as nurses with a bachelors degree? THanks!
