Pharmaceutical Calculations: 1001 questions with answers is a compilation of multiple choice pharmaceutical calculations questions. The questions in this book have been strategically developed to prepare the user for the rigor of the calculations questions that frequently appear on the North American Pharmacist Licensure Examination (NAPLEX®).
Consequently, this book is organized into six main parts. Part 1 is a review of the fundamental math needed for pharmaceutical calculations. The remaining parts of this book are based on the sections pertaining to calculations delineated in the National Association of Boards of Pharmacy (NABP) NAPLEX® blueprint. Chapter topics in part 2 through part 6 have been logically arranged under the appropriate sections. This arrangement provides the reader with a workable structural framework for mastering pharmaceutical calculations in regards to the NAPLEX® exam.
Pharmaceutical Calculations: 1001 questions with answers is not a textbook. It is not designed to compete with the numerous excellent pharmaceutical calculations textbooks already available on the market. Rather, the intent of this book is to serve as a resource to provide guided additional practice that several students seek at a level comparable to the NAPLEX®.
The chapters in Pharmaceutical Calculations: 1001 questions with answers contain a healthy mix of what may be considered easy, medium and difficult questions.
Therefore this book can help cement concepts imbibed during personal or class study and can aid in gaining mastery in pharmaceutical calculations if used correctly. Since accuracy and speed are critical for the NAPLEX® exam and in practice, the reader is encouraged to revisit concepts when an incorrect answer is obtained. Furthermore, each question should ideally be correctly solved in less than 90 seconds once a decent level of proficiency is attained in prior studies. Additionally, it is recommend that not more than a single section of the book be completed in one sitting. Instead sufficient time should be allowed so that concepts worked on in a section can be mastered.
To help with mastery, answers to questions are provided at the end of each chapter. Also, step by step video solutions for several questions and an online test bank are available on https://rxcalculations.com. Additionally, you may download the companion NAPLEX® Calculations Prep App so you can practice pharmaceutical calculations on the go. The app is available for free on the Google Play and Amazon App stores.
