Precepting in the PICU

Hello all! I am for sure doing pediatrics when I graduate (a year). I was always drawn to NICU and thought that was what I wanted to do. But, after clinicals I feel in love with the pediatric ICU. There is just something about it that I was drawn to more than the NICU.

I got into a clinical elective this summer for the PICU. I will have a preceptor for 90 hours over the course of 3 months. I was wondering if there was a PICU nursing book that would help me out before I start? I know that there is so much to learn about the PICU. I am looking for a book that discusses common diseases/injuries, what to do, and procedures. For example...this is what a PICC line is, this is how you draw blood from it, stuff like that. And for the diseases/injuries...for instance with increased ICP what kind of care should you follow? I.e-keeping the head of the bead elevated. Obviously more complex but is there a book like this that exists that will give me an edge? So that when I walk in there I will be more confident.

I have tried bookstores but they all have to be ordered online. So, any advice will be great. (I dont want to spend $60 on a book I wont use) Thank you guys for all your help
