we can buy only the chapters we need in the new medsurge book link here

http://lww.vitalsource.com/show/1609135377CH23 seeing as though excelsior changed the medsurge book on us, and many of us like myself are on the last test i didn't want to have to buy a brand new book. i found a legitimate lippincot site where you can just buy the chapters you need or the whole book. and they are giving a 14 day free trial of chapter 23 which we need for tuberculosis on ls3.. the other chapters cost only $1.68. Buying all the chaps cost as much as buying a whole book but this is a good option if you can't afford to buy the book all at once or you only need it for your last test etc....Forgot to mention it is a download so you will not have a tangible book in your hand but it will be on your computer.
good luck. This is not my website by the way, it is a legitimate site by the publishers just trying to help out my fellow students.
