Drug Calculations meets the needs of nursing courses that teach the ratio and proportion method for drug calculations. This title is one of the five Elsevier drug calculations texts. Of the others, Morris, Kee, and Ogden, include instructions on more than one drug calculation method, and Turner includes instruction on the dimensional analysis method only. Drug Calculations is the only title on our list that strictly covers the ratio and proportion method. It provides extensive coverage of drug calculation topics, and it presents clear, step-by-step explanations and examples of how to perform drug calculations using the ratio and proportion method. This new edition will include several updates related to safe medication administration, new medications and drug labels, and updated NGN practice problems and case studies.
