Finding a nurse mentor

[Med Surg RN, BSN, RN]

Hi everyone! Can someone provide advice on how I can find a nurse mentor? As a nursing student, I volunteer and have clinicals at prominent NYC hospitals, but in both instances, I always find that the nurses are too busy to talk to. I feel like every minute I take to ask questions, is time taken away from their work and the last thing I want to do is inconvenience them. I just do my best stay out of the way. For the most part, I have found CNAs to be more approachable and usually I bug them for tasks that I can do on the floor to help them out.

I would really like a mentor, who I can go to for guidance. What is the best way to do this? I searched allnurses but couldn't really find anything. If I missed some relevant threads, please direct me to them. Many thanks!!!
