DRUG DOSAGE CALCULATIONS: A MULTI-METHOD APPROACH introduces all three of today’s leading methods of dosage calculation: Dimensional Analysis, Ratio & Proportion, and Formula. It walks step-by-step through solving dosage problems utilizing all three methods, often comparing multiple approaches to solving the same problem side-by-side. Instructors can choose their preferred method, and students can become expert with all three, ultimately choosing the approach they find most efficient. Unit I offers a diagnostic arithmetic test, reviews basic math skills, presents essentials of medication administration, and offers an easy, common sense introduction to dimensional analysis. Next, the text introduces essential metric and household medication systems and conversions. Then, building on these foundations, the text offers in-depth coverage of calculating oral, parenteral, intravenous, and enteral dosages, including flow rates, titrating IV medications, pediatric dosages, and daily fluid maintenance.
