In a growing range of health-care settings, nursing and allied health professionals are assuming increasing responsibilities in every aspect of drug administration. The first step in assuming this responsibility is learning to calculate drug dosages accurately. Dosage calculation is not just about math skills, it is an introduction to theprofessional contextof drug administration. Calculation skills and the reason for their application-this is whatMedical Dosage Calculationshas taught thousands of students with unmatched success through seven editions. Medical Dosage Calculationsis a combined text and workbook designed for the student of dosage calculations. Its consistent focus on safety, accuracy, and professionalism make it a valuable part of a dosage calculation course for nursing or allied health-care programs. It is also highly effective for independent study and may be used as a refresher to dosage calculation skills or as a professional reference. Topics introduced and developed inMedical Dosage Calculationsinclude: basic arithmetic skills systems of measurement dosage calculations for all common forms of drug preparations IV and specialized calculations In addition to these topics, this edition includes substantially more information about basic drug administration. Readers will learn how to interpret actual drug labels, package inserts, and various forms of medication orders, as well as how to recognize a wide variety of syringes. Key Features ofMedical Dosage Calculations We have built on the strengths of the previous editions by continuing to provide the thoroughness of a textbook with the practicality and convenience of a workbook. Here are the important features that have madeMedical Dosage Calculationsan effective and popular book through seven editions. Dimensional Analysis Calculation Method.Dimensional analysis is a technique in which the units on the drug package are systematically converted to the units on the drug order. Conversion factors have traditionally been used to simplify complex calculations in physics and chemistry. However, before the first edition of this textbook in 1972, these methods had not been applied to drug calculations. Dosage calculation methods were limited to either theratio-and-proportionmethod or the use ofmemorized formulas.Our innovation in dosage calculation has come to be imitated in many textbooks and accepted by an ever-increasing number of medical professionals over the three decades since we coined the phraseDimensional Analysis. Learn by Example.Each chapter unfolds basic concepts and skills through the use of examples. Case Studies.Realistic case scenarios allow the student to apply concepts and techniques presented in the text to a clinical setting. Problem Sets.This text/workbook offers learners more than 1000 practice opportunities. Answers to all but the Additional Exercises can be found in the book. Answers to the Additional Exercises are in the Instructor's Guide, and on the companion Website. Each chapter's practice opportunities are grouped into four problem sets: Try These for Practice Exercises Additional Exercises Cumulative Review Exercises Comprehensive Self-Tests.Upon completion of this text/workbook, these Self-Tests quiz the students' comprehensive knowledge. Answers to the Self-Tests can be found in the book. Organization.The skills mastered inMedical Dosage Calculationsare arranged into four basic learning units: Unit 1: Basic Calculation and Administration Skills After a review of basic number skills, this section introduces the essentials of drug administration. A separate chapter introduces dimensional analysis using a friendly, commonsense approach.<
