I think if you show that you are willing to learn and put in the work it takes to get yourself to a higher level of thinking, communicating, and learning your skill set.. you will be fine. Utilizing other resources and not taking a needy approach also helps. I am a new RN but worked as an LPN for quite awhile and was always complimented on my willingness to learn and take initiative. Don't do anything your not comfortable with,but be willing to get comfortable with it. Good luck.. and yes... some nurses are just plain MEAN!! It takes awhile, but with the right attitude you will earn the respect and trust of others.
