This dosage calculations textbook is designed expressly for use in Canadian schools of nursing. It teaches three methods of dosage calculation—ratio and proportion, cross-multiplying of fractions, and formula—using the SI Unit system of measurement. Plentiful sample questions from across nursing care settings with clear use of the three calculation approaches give students immediate opportunity to practice each step taught. Canadian drug trade names are used throughout the text.

The book includes self-tests to help students identify areas that require further practice. Make a Note boxes reinforce underlying theory. Keep It Safe boxes emphasize important elements of safe practice.
