Dosage calculation rounding practice
Keep the full calculated value while you are still working. When the question states the final precision, look one digit to the right of the place you are keeping to decide whether that final digit stays the same or increases. Do not invent a rounding rule when the question or applicable instruction has not supplied one.
Formula
nearest tenth: inspect the hundredths digit; nearest hundredth: inspect the thousandths digit
For medication dose notation, use a leading zero for values below 1 and avoid unnecessary trailing zeros. Device resolution, product instructions, assessment rules and local policy can determine the usable final precision.
Sample question
A practice calculation gives 2.46 mL and asks for the nearest tenth. What is the rounded result?
The tenths digit is 4 and the hundredths digit is 6, so the tenths digit rounds up.
Answer: 2.5 mL

Identify it
Recognise the lesson’s key idea, the values that belong in the calculation and the unit the answer needs.
Calculate it
Use clearly stated orders and supplied information to complete straightforward calculations.
Interpret it
Handle frequency, totals, conversions, order changes and realistic but relevant detail.
Reason through it
Reason through dense ward stories, changed orders, competing numbers and multi-part calculation chains.
Learned means the lesson is complete. Practised means you have attempted questions. Secure requires a strong unassisted run. Mastered requires strong evidence again after time has passed. Review due means a previously stronger skill is ready for retrieval again.
