College: Nursing Interview?

I've got a nursing interview at my college and I am so nervous! Are any of you applying to or currently in your school's Nursing program and have tips that can help me?
I get so nervous in situations like that. I try not to, but just thinking about it gets me so worked up, my mind goes blank, my hands shake, I feel uncomfortable...etc. I know they're just regular people, so why am I so nervous?
I am truly passionate about Nursing. I hope to become an RN in Pediatrics. I just love kids. I know that when I become a mother I'd do anything and all that I can to help my kids if they were sick or has a "boo-boo" :oD
I've been told that the interviewers like something unique. Like they don't wanna hear all the time, "I wanted to be a nurse since I was a kid." "Just to help people." I know that they might want some kind of background story that supports how passionate I am. But I don't think I have one. I just know that I'm good with kids and I hope to be a great parent to my own.

Help?

1) Relax
2) Be Clean and Neat
3) Rehearse your background knowledge and be able to
tell your interviewer your skills and interests
4) Be Yourself, people have Stuffiness
5) Envision..See yourself doing the Job you dream of
6) If you are Religious...Pray before Interview
7) Get a Good night's sleep before your Interview
8) Give a good Handshake
9) Take 15 (Minutes) ...out of your life to be there Before
the interview..employers love people who take the
initiative rather than just "be on time"
10) Ask questions..that way you are not only being
interviewed...you are proactively working with
your interviewer and showing a common interest
and willingness to be part of the team
