Just remember these people probably do not see enough critical patients to realize that what you were doing was providing access that would deliver a large amount of fluids in the quickest time. They are probably intimidated by your knowledge and feel you are "one upping" them. I find the best way to help in this situation is to find a staff member that everyone likes and start to develop a work relationship with them. This person probably will have a good work ethic and will be able to bring you into the fold. These people could benefit having a nurse with your skills on the unit, they just don't know that yet. Good luck.
