Developing methods for solving drug dosage calculations.

This second part of a three-part series of articles examining drug calculation skills, focuses on the different methods that can be used to solve drug calculations. It builds on Part 1 (Supporting the development of calculating skills in nurses, 18(7): 399-402), and provides examples of different methods that can be used to plan and solve a range of common calculations, such as weight-based calculations and weight and volume calculations. The framework introduced in Part 1 is used to support the planning and solving of drug administration calculations.
