Drug calculations part 1: a critique of the formula used by nurses

Kerri Wright Senior lecturer, University of Greenwich, London

The role of mathematics is integral to nursing practice, and careful and accurate calculations are important to help prevent medication errors. This two-part article examines different methods for solving drug calculation problems. The first part critiques the commonly taught nursing drug calculation formula. Part 2, to be published next week, explores a range of other methods that are used in practice to calculate drug dosages.
