Medication label reading practice
Read strength as a relationship. A label stating 250 mg in 5 mL means those two values belong together; it can also be expressed as 50 mg/mL. A separate bottle volume describes how much product is in the container and does not automatically change the stated concentration.
Formula
concentration (mg/mL) = medicine amount (mg) ÷ stated volume (mL)
Use the current product and prepared-state information. A dry-powder amount, pack size or vial size does not by itself provide a usable liquid concentration.
Sample question
A fictional medication label states 250 mg in 5 mL. What concentration does that represent?
250 mg ÷ 5 mL = 50 mg/mL
Answer: 50 mg/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.
