I would just like to say that the text books aren't always accurate; you have to ask, because within cultures there is wide diversity. I live in a 90% Mexican-American community and the things I learned in nursing school weren't correct. Its taken me nearly my whole 9 years here to begin to have an understanding.
Good luck in your new job. Be humble, keep your ears and eyes open, and mostly keep your mouth shut unless you're asking questions!
