Medication Reconstitution Practice Questions
Practise reading verified reconstitution information, separating liquid added from the final prepared result, calculating a prepared concentration and then finding the volume that contains the ordered dose.
Medication reconstitution calculation practice
Quick review before you start
Use the resulting concentration directly when it is stated. If a verified final prepared volume is supplied instead, calculate the prepared concentration from the medicine amount and final volume first. Then divide the ordered dose by the prepared concentration to find the dose volume. Do not assume that liquid added equals final prepared volume.
Formula
prepared concentration = medicine amount ÷ final prepared volume; dose volume = ordered dose ÷ prepared concentration
Real preparation instructions are product-specific. The calculation only becomes valid when the exact preparation information needed for that medicine and presentation has been verified.
Sample question
A fictional 1 g powder vial has a verified final prepared volume of 10 mL. The practice order is 360 mg. What concentration is prepared, and what volume contains the ordered dose?
1 g = 1000 mg; 1000 ÷ 10 = 100 mg/mL; 360 ÷ 100 = 3.6 mL
Answer: 100 mg/mL and 3.6 mL
What these questions practise
- identifying powder amount, liquid added, final prepared volume and resulting concentration
- using a stated resulting concentration without inventing a final physical volume
- matching g and mg before calculating mg/mL
- calculating the ordered mL after the prepared concentration is known
- recognising when the preparation information is incomplete or conflicting

What the learning states mean
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.
