I am studying for the Nursing Professional Development certification exam. Unfortunately, there are no review courses near where I live. I bought the NPD certification review manual from ANCC, but it only has 40 practice questions. Has anyone used the Core Curriculum for Staff Development book that you can buy from NNSDO? I know it's over 600 pages, but I heard there is a question bank in it - anyone know how many questions and are they helpful??? Any help would be greatly appreciated. Thank you!
