I don't think so, but honestly, I'd purchase the Taber's Medical Dictionary (you NEED this, it's invaluable on the Touch) and call it good. Those two books are what you're going to use 80% of the time in clinicals. You can add other texts, too, but if I were doing it over, I'd pass on the Nursing Central and instead buy Harrison's, Davis' Drug Guide, and Taber's.
You are going to LOVE having these books on your Touch, easily accessed anywhere! Make sure you get a case and screen protector for your device. I also started buying only scrub pants with a leg pocket, to keep my Touch in. Safer than a scrub top pocket and easy to get to.
Make sure you check out all the free and low-cost medical apps in the App store, and the nursing podcasts that are free on iTunes!
