I purchased the text they recommended (Pharmacology 2nd edition Reviews & Rationales by Prentice Hall) found at your nearest bookstore. I did take the practice test provided by the hospital. It gave me an idea of how the exam is formatted. Yes, it was extremely helpful. There are so many drugs to memorize however, all you need to do is bunch the meds into categories and memorize them as so. Know administration considerations, side effects, adverse effects, nursing considerations, and client education.
