I recommend this book:
http://www.amazon.com/All-One-Care-P...ref=pd_sim_b_5
You won't use it as much during your first semester(so you might hold off until 2nd semester) but each semester afterward, it will come in handy. There is a care plan book on the required books list, but more than one resource for your concept maps is a good idea.
- go ahead and buy a couple of reams of printer paper and some extra ink cartridges unless you live close to a kinko's because you'll be printing alot of stuff.
- get a stethoscope that YOU hear well with. Some people have great results with the sprague style, while others find Littmans to work better for them. I use a Littman Lightweight II SE...it's not a high end scope but I hear well with it.
