## Overview

This popular worktext provides all the information, explanation, and practice you need to competently and confidently calculate drug dosages using the ratio and proportion method. Full-color chapters present material from simple to complex, following a step-by-step format for each problem. The answer key includes a unique "proof" step, ensuring that you understand each calculation and can easily double-check your answers.

• Ratio and proportion method used throughout presents a logical, accurate, and consistent method of calculation.
• Step-by-step format of problems includes a unique "proof" step in the answer key to ensure that you understand the solution.
• Clinical Alerts integrated throughout warn you about potential and common drug dosage and calculation errors.
• Critical Thinking Exercises with a variety of patient scenarios help you gain practice integrating computation and analytical skills for optimum patient safety.
• Chapter objectives and introductions help you prepare for learning and focus on what you should accomplish.
• Worksheets follow each section, giving you the practice you need to master math calculations.
• Multiple-Choice worksheets feature answers completely worked out in the answer key, giving you the opportunity to use critical thinking skills to analyze possible answers, discard incorrect responses and select the correct answer.
• A Comprehensive Final covers all topics in the book and allows you to evaluate your overall mastery of drug calculations.
• Full-color drug labels and equipment illustrations provide a realistic representation of medication administration.
• Drug Calculations Student CD-ROM (Version III, packaged with the text) is an updated, interactive tutorial with a brand-new design for easier navigation. Covering various drug calculation topics (such as oral, parenteral, pediatric, and intravenous), it includes animations and interactive exercises, plus 565 practice problems covering ratio and proportion, formula, and dimensional analysis methods, and a comprehensive post-test.

• Current guidelines from The Joint Commission (TJC) and the Institute for Safe Medication Practices (ISMP) help you reduce medication errors and increase patient safety.
• Over 150 new practice problems increase your opportunities to practice and apply what you've learned.
• Updated drug labels and equipment photos (including pumps and IV equipment) familiarize you with what you will encounter in the clinical setting.
• New content in the Safe Medication Administration chapter features critical abbreviations, quizzes, and a comprehensive summary of safe medication practices for improved patient safety and quality care.
• Updated coverage of insulin including new worksheets on insulin dosages and new products that currently on the market to better prepare students for the clinical setting.

## Editorial Reviews

Diane Aschenbrenner
General mathematic information and information specific to calculating drug dosages for various ages, types of drugs, and routes of administration are provided in this book. The intent is to teach dosage calculation to students, offer review, and serve as a reference for nurses. This is one of many dosage calculation books on the market. Nurses and nursing students are the intended audience. This book is clearly laid out with nice pictures and illustrations. Information is presented in small segments with multiple practice opportunities. The critical thinking exercises are clinically relevant, demonstrating potential medication errors in practice. The reader must identify the root cause of the error and explore ways to prevent the error. Nice inclusions are the chapters on insulin (includes all routes of administration, including pens, implantable pumps, and oral hypoglycemics -- but this may confuse students as these are not forms of insulin), anticoagulants (all routes of heparin and warfarin), and advanced IV calculations (information often grouped as critical care calculations, plus TPN). There is not have extensive information on drug administration principles or pharmacological principles related to drug therapy as found in other books. However, this information is well covered in fundamental and nursing pharmacology texts, and the authors' decision to focus on practice problems and critical thinking exercises seems justified. Unfortunately, the brief information on administration may allow students and nurses to make some errors in practice. Two examples: the authors' comment on site selection for insulin administration does not strictly follow the American DiabeticAssociation's position, and when they give the direction to add an air bubble when giving heparin SC they neglect to state that the needle should be changed first to prevent an inaccurate dose in the syringe and a medication error. One major omission was the formula for computing body surface area, which is included in other books such as Gray's Calculate with Confidence, 2nd Edition (Mosby, 1998).
