Seeking nursing career with a tattoo on wrist?

I have a monarch butterfly tattoo on the inside of my wrist. I am currently going to college to become a RN and plan on getting my master's in nursing in the future. Will my tattoo hinder me in my career? I've heard some hospitals don't allow exposed tattoos, is this true? It's a very beautiful and harmless tattoo, I don't see how anyone could be offended by it. Also I am concerned with health concerns my employer may have about me having a tattoo.
