-I used the Med-Surge text more than anything else. Unlike Basics, you really need to read the text and supplement your notes prior to class if you have time.
-I didn't buy the "Manual of Diagnostic & Lab Test" book because the info is in the back of the text.
-I used the "Intravenous Medications 2010" book 3 times in class--shouldn't have purchased it.
-The Clinical Companion was nice to have because it gave a shorter synopsis of the various conditions, but its not essential.
I used the Med Surge Success, A Comprehensive review for NCLEX-RN (any of the comprehensive books will work), and the Care Planbook by Ulrich & Canale. I used the Med-Surge Study Guide a few lectures because there were a lot of test questions for certail sections. Just make copies of the Study Guide from the library for any section you want. It's time consuming so I would just copy the answers from the back of the book and go from there.
Hope this helps.
