Dosage calculation can be very challenging and intimidating for students, however, veteran author, Anna Curren breaks down this subject using the dimensional analysis method which reduces all calculations into a single, easy-to-solve equation. This takes the fear-factor out of manual math altogether. Many students have raved about how previous editions of this text helped them through their medical math course and succeed in clinical practice. The Sixth Edition of Dimensional Analysis for Meds: Refocusing on Essential Metric Calculations has been streamlined to present only the essential information. The first chapter begins with an overview of the metric system; as Curren states, 98% of all calculations involve metric measures. The text is structured to feature content in small instructional steps followed by assessments to reinforce what has been learned. To prevent annual hospital drug dose errors, the latest drug dosage abbreviations and metric notations are included.
