Description

Ratio & Proportion Dosage Calculations is a combined text and workbook.  Its consistent focus on safety, accuracy, and professionalism make it a valuable part of a course for nursing or allied health programs. It is also highly effective for independent study, and may be used as a refresher for dosage calculation skills and as a professional reference.

 

This book uses the Ratio and Proportion method for drug calculations; a time-tested approach based on simple mathematical concepts.  It helps the student develop a “number sense”, and largely frees the student from the need to memorize formulas.
