Confident Calculations: The Easy Guide to Drug Calculations for Student Nurses

By Dr Benjamin Olusola Ajibade

Drug calculations don't have to feel like a threat to your career.

Most nursing students who struggle with drug calculations aren't bad at maths. They were taught formulas to memorise instead of reasoning to understand, and the anxiety that follows has little to do with ability and everything to do with how the subject is usually taught.

Confident Calculations rebuilds the whole subject from first principles, one clear idea at a time, from core numeracy through tablets, injections, IV rates, and paediatric dosing, all the way to the confidence and checking habits that carry into real practice. Nothing is presented as a formula to memorise. Every method is built up from a plain, honest explanation of why it works, so it holds up under exam pressure and on a busy ward, not just on a familiar practice sheet.

What's inside:

Six parts, building from foundations through to confidence under pressureEvery calculation method explained from first principles, not just handed to you as a formula to apply116+ practice questions across four graded practice sets and three full 20-question mock assessmentsQuestions and worked solutions kept separate, so practice is genuine, not just answer-checking"Spot the Error" boxes and a "Before You Calculate" checklist that build real clinical judgement, not just arithmeticRealistic prescription charts, medicine labels, syringes, pump screens, and insulin pens to practise reading, not just calculatingGrounded in current UK NMC standards and NHS medicines-safety guidance, including recent insulin device safety updates

Written for pre-registration nursing students working toward the NMC's required 100% pass mark in medicines calculation, and equally useful as a refresher for newly qualified and experienced nurses who want to rebuild genuine understanding underneath years of habit.

Understand it. Calculate it. Check it. Decide safely.
