The ratio and proportion and formula methods, the two most common methods used in clinical practice, are included in the text, along with an extensive math review and large number of examples and exercises. The second edition features numerous new drug labels, syringes, and other illustrations, many in full colour to simulate clinical reality. Critical thinking activities and a "Critical Thinking to Avoid Drug Calculation Errors" feature encourage application skills. New sections on patient education and home care considerations are added in Chapter 9. Chapter objectives, a more user-friendly answer key, and perforated and three-hole punched pages make this book easier to use for both instructors and students.
