Henke's Med-Math

Book excerpt: Now in its Sixth 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 presents all four methods of calculation side by side: ratio, proportion, formula, and dimensional analysis. New material on enteral feedings, heparin infusions, and insulin infusions is included. Drug labels are current, and problems use JCAHO-approved abbreviations. A handy quick-reference plastic pull-out card shows conversions and formulas.
