Learn to calculate dosages accurately and administer drugs safely! Gray Morris’s Calculate with Confidence, Second Canadian Edition uses a clear, step-by-step approach to make drug dosage calculations easy. More than 2,000 practice questions help you review basic math and then master the three standard methods of dosage calculation: ratio and proportion, formula, and dimensional analysis. With the increasing responsibility of the nurse in mind, emphasis is placed on critical thinking and clinical reasoning in preventing medication errors. Reflecting current practice in Canadian health care, this book also provides excellent preparation for Canadian licensure exams!
