First Assignement

Hey there all - I am one month into my first assignment here at NC Baptist Hospital. I interviewed for a cardiac position, but got placed onto a trauma floor. - OOOOOPS!!! I talked to my recruiter about it last week and she was very surprised. She plans to follow up with the facility. Meanwhile, when I got here, I brushed up on my trauma, traction, collar, knowledge base - Should I have called my recruiter that first week?? I honestly believe that there is nothing here that I cannot do or become familiar with, but should I have called earlier?
Just seeking opinions.
