relax!! that's the first piece of advice i have to give you. it will take time but your point of view will alter some. remember that not every one who comes in will be critical! your coworkers will test you but hopefully they won't throw you to the wolves. trust in your knowledge base. you won't freeze when it matters and if ya do - your coworkers will help. take a deep breath and enjoy it!
good luck. remember to slow down and think your way through a crisis.........even when things are moving quickly. take a breath and then go. rely on your previous knowledge and skills. plan to work harder than you have before on some days. you are the first line of health care so your assessment skills are crucial! don't be afraid to ask questions of people and coworkers. for multi cultural areas you really need to find a way to communicate through language barriers. it won't take long to figure out how people react to things - some are full of drama and some are stoic. (again with the assessment skills) it's sooooo much fun! enjoy!!!
