Clinical Calculations: A Unified Approach

The original is now a classic. Clinical Calculations was the first text to introduce the dimensional analysis method of calculating dosages, an approach rapidly becoming the method of choice for nurses. The fifth edition of this trailblazer showcases its proven strengths: a clear writing style, workbook-style format, strong IV therapy content, and clinical applicability. Critical thinking is encouraged in conjunction with memorized rules by asking learners to always consider whether their answers make sense. It does this within the context of providing the core knowledge-base for dosage calculation and administration for learners of all levels and experience. Chapters cover the range of practice, including systems of measurement, oral and parenteral medications, basic and advanced intravenous medications, and pediatric dosage. Just as the title suggests, this resource is the ideal tool for calculation in a clinical setting. With copious reference tools, outlined injection sites for IV therapy, and unique performance criteria for evaluating nurse competency, the tradition of excellence and innovation continues.

In easy-to-understand language, this text teaches the label factor method (dimensional analysis) for solving dosage problems through a wide variety of computational applications typical of the clinical setting. Includes added content on the use of the label factor method for nutritional calculations and abundant learning aids:over 100 drug labels, numerous solved examples, practice problems, step-by-step procedures, self-quizzes, and performance criteria checklists.

This Fourth Edition text introduces dimensional analysis as the method for calculating all drug dosages. The use of a single, consistent method for dosage calculations helps eliminate confusion, reduce errors, and build confidence. This book applies the dimensional analysis approach to all three systems of measurement, metric, apothecaries, and household, with an emphasis on recognizing relationships among the three systems. Readers are required to memorize only a few basic equivalents and they're on their way to mastering dosage calculations.
