### Summary

Now in its Fifth Edition, this best-selling text features a highly visual, hands-on approach to learning dosage calculations and principles of drug administration. It presents step-by-step approaches to solving problems and includes dosage problems that simulate actual clinical experience. Each chapter includes numerous examples, self-tests, and proficiency tests. This edition covers all four dosage calculation methods--formula, ratio, and proportion side by side in each chapter, and dimensional analysis in a new chapter. Drug labels are current, and problems use JCAHO-approved abbreviations. A handy quick-reference plastic pull-out card shows conversions and formulas. A bound-in CD-ROM contains dosage calculation problems and a medication administration video.
