The UK Nursing and Midwifery Council (NMC) Computer-Based Test (CBT) for Midwifery is a critical step for international midwives looking to practice in the UK. Part A is specifically the Numeracy module, designed to ensure you can safely perform the calculations required in a clinical midwifery setting.

Part A: Numeracy Overview

Part A is taken in the same sitting as Part B (Clinical), though they are graded independently. If you fail Part A but pass Part B, you only need to resit Part A.

Core Topics Covered

The questions are not abstract math; they are scenarios you will encounter on a labor ward or in community care. You will be provided with an on-screen calculator during the exam.

• Medication Dosages: Calculating the correct dose of a drug based on the concentration available (e.g., Dose Required ÷ Stock Strength × Volume = Amount to Give).
• IV Infusion Rates: Working out drops per minute or mL per hour for intravenous fluids or oxytocin drips.
• Fluid Balance: Calculating total intake and output over a specific period.
• Metric Conversions: Converting between micrograms (mcg), milligrams (mg), and grams (g), or milliliters (mL) and liters (L).
• Unit Weight Calculations: Dosage based on the mother’s or neonate’s weight (e.g., mg/kg).

Key Rules for Part A

To avoid “technical” fails, you must follow the NMC’s strict formatting rules for entering your answers:

• Numbers Only: Do not add units (like “ml” or “mg”) unless the question specifically asks you to include them.
• Decimal Precision: Follow instructions on rounding carefully. Generally, you should not round until the final step.
