Preparing for the NMC CBT Part A – Numeracy is a crucial step for any international nurse or midwife aspiring to work in the UK. While it may seem straightforward, this section plays a vital role in assessing your ability to perform safe and accurate calculations in real-world clinical settings.
At Fortuwest International Training and Education, we help candidates build the confidence and skills needed to pass this test successfully. Here’s a breakdown of what to expect—and the six key numeracy topics you need to focus on.
Understanding the NMC CBT Part A – Numeracy Format
Before diving into the topics, it’s essential to understand the exam structure:
- 📝 15 questions
- ⏱️ 30 minutes
- 💯 1 mark per question
- ✅ Calculator allowed
- 📌 All questions are applied in clinical nursing or midwifery settings
- Answers must be in single number format (some require units)
1. Medication Dose Calculations
One of the most important areas is calculating the correct medication dose. Nurses must interpret drug charts and prescription details accurately. You’ll encounter questions involving:
- Dosages based on weight
- Available stock strength
- Syringe or medicine cup measurements
- Ratio and proportion calculations
🔍 Example: A patient needs 250 mg, and you have a 125 mg tablet. How many tablets do you give?
Mastering this helps prevent both underdosing and overdosing—key to patient safety.
2. Metric Conversions
Healthcare professionals in the UK use metric units exclusively, and understanding conversions is essential.
Common conversions include:
- mg ↔ g
- mcg ↔ mg
- ml ↔ L
Being quick and confident in these conversions improves accuracy and speed during the test.
✅ Example: Convert 1000 ml to 1 litre, or 500 mg to 0.5 g.
3. Oral Medication Calculations
You’ll need to calculate correct doses for oral medications such as tablets, suspensions, or liquids. These questions often involve matching the prescribed dose to the available stock.
💊 Example: A prescription says 250 mg, stock is 125 mg tablets—how many do you give?
Regular practice with these simple yet essential calculations will boost your exam performance.
4. Injection Dosages
When administering injections, you’ll deal with ampoules and vials. The exam may ask you to calculate how much to draw up based on the concentration.
💉 Example: If a vial has 1 g in 2 ml, how many ml do you need for 500 mg?
These questions test both your math skills and clinical safety awareness.
5. Intravenous (IV) Infusions
IV infusion calculations are critical due to their real-time impact on patient care. You may be asked to:
- Calculate ml/hour
- Determine drops/minute
- Adjust flow rates based on infusion sets and prescriptions
Practicing these helps avoid serious errors in real clinical situations.
6. Fluid Balance Monitoring
Understanding fluid intake and output is key in patient care. You’ll need to calculate:
- Total fluid input/output over 24 hours
- Fluid deficits
- Daily balances from fluid charts
This topic assesses your ability to interpret and apply real clinical data—an important part of day-to-day nursing duties.
Final Thoughts: Build a Strong Foundation in Numeracy
While CBT Part A – Numeracy may seem simple at first glance, it forms the foundation for safe and effective nursing care in the UK. By focusing on:
- Dose calculations
- Metric unit conversions
- Oral and injectable medication dosages
- IV infusion rates
- Fluid balance monitoring
—you’ll not only pass the test but also feel more confident in clinical settings.
🧠 Tip: Practice consistently, review your methods, and always double-check your answers for accuracy.
