In what situations will this article be useful to me?

This research study tested 229 second year student nurses and 44 registered nurses on key calculation skills such as addition, subtraction, multiplication, division, fractions, decimals, percentages and conversions. And it tested them on the main types of drug calculations such as dosage calculations for solid and liquid oral medication and injections, and intravenous fluids. This study showed that both students and nurses were able to perform calculations for solids, oral liquids and injections more easily than calculations for drug percentages, drip and infusion rates. This article highlights the need for regular practice in drug calculation to maintain skills.
