Gray Morris's Calculate with Confidence, 2nd Edition

The second Canadian edition of Gray Morris’s Calculate with Confidence continues to emphasize safety in medication administration and is written to meet the needs of current and future practitioners of health care at any level. This book can be used as a resource for any education program or practice setting that involves dosage calculation and medication administration by health care providers.

Gray Morris’s Calculate with Confidence, Second Canadian Edition, primarily uses the metric system in calculating dosages, but it presents examples that incorporate imperial system (household, apothecary) measurements where applicable. Specifically, you will see the conversion of pounds to kilograms in some examples because weight is still sometimes measured in pounds in the community at large. Therefore it is prudent to include imperial units of measurement in this book.

The second Canadian edition of Gray Morris’s Calculate with Confidence illustrates the standard methods of dosage calculation: the ratio and proportion method, the formula method, and the dimensional analysis method. With the inclusion of all three, instructors have the freedom to decide which method(s) best suit their program, and students have the same freedom to choose the method that facilitates correct dosage calculations.
