Help with my first interview in a medical setting!

Hi all! This is my first (or second) post on here, so let me introduce myself. My name is Stacey, I just graduated in September (hence the screen name) and I am in that awkward stage of studying for my boards and wishing I had a job. I live in GA, about 30 minutes away from Atlanta. I am very apprehensive about my first interview because I have never had a professional job, thus I have never had a professional interview. The extent of my work history is waitressing, daycare, and Starbucks ;o)
I am really regretting not having any medical experience under my belt because I have NO IDEA what they are going to ask me in my first interview. Will they ask scenario-type questions? Will they ask the stereotypical interview questions like "Tell me about a time you could have handled a situation better." I did have to have an professional-type interview with the entire nursing staff at my school in order to gain acceptance into the program. Each staff member scored my interview and the scores were totalled up and if the number was satisfactory, you passed that part of the admission process. That's about the extent of my experience in interviewing. I have a tendancy to get very nervous and insecure in an interview setting, and have been known to "draw a blank" so to speak.
If anyone can give me some interview pointers, I would be GREATLY appreciate it!
For the most part, I understand dress code, how to act, and so on...the main things I am nervous about are the types of questions asked and how to prepare ahead of time.
Thank you in advance and sorry for the lengthy post!! -Stacey
