I think one thing to remember is the material doesn't change (unless were talking about evidence based practice and such), but the basics of nursing are going to remain the same. For instance, what you would do FIRST for a patient who is in respiratory distress is not going to change from one year to another. As long as the book you are going to use to study helps you implement critical thinking as well as apply the knowledge you will learn, you should be good to go! Good luck!
