In our paramedic class we have the Nancy Caroline Emergency Care in the Streets, Sixth edition. You can get it as one full hardcover (Huge brick or weapon) or sets. I think some places if you order them it comes with the Hardcover and a workbook which is helpful when studying. The only other thing though worth mentioning about this is, the Seventh Edition should be coming out next year I believe. So far this book as been pretty up to date besides ACLS and AHA guide lines being old . Great book in my opinion, I have a link to the hardcover from Amazon.

I would recommend getting it "used in good condition" because it will be a heck of a lot cheaper.
Oh correction the Seventh Edition volume 1 is out but volume 2 will be out in the spring of 2012. So I guess the seventh is going to be two books so I don't know how helpful that will be to you as of right now with it being two books and the 2nd volume coming out in spring.
