RN out of practice for over 2 years, looking for Refresher Courses.

Hi,

I'm an RN with, I would say, "moderate" experience clinically. Meaning, after graduating in 2000, I only ever worked part-time so never got lots of full-time bedside under my belt. I did do hospital (ortho) for 6 years, but the last 2 years of that 6 years I was on-call, and worked seldom. For the past two years now, I've been a stay-at-home mom doing an telephone nursing job screening clinical trial applicants, one day a week. I am looking for a refresher course or internship, or something to help me get back up to speed to do clinical again. I'm in the Portland area.
