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.
