Invest in the Straight A's in Nursing series books. The info is outlined in a bullet point format with NCLEX or nursing school style questions in the back of the chapters. Plus, there is a CD-Rom in the back of the book with tons of questions (I have seen some of these questions appear on exams) and the rationale.
Med-Surg, Psych, Pharm, Ob, Peds, etc... are available.
These books are set up to cut through all the extensive reading and learn the critical points along with meds you will see prescribed with these conditions and the nursing theory applied - assessment, diagnosis, planning, intervention, and evaluation.
