Medication Infusion Rate Practice Questions: mg/hr & mg/min
Practise separating a pump's mL/hr from the medication dose rate represented in mg/hr or mg/min. Questions progress from direct concentration calculations to time-unit conversion, conflicting values and infusion-state checks.
Medication infusion rate practice
Quick review before you start
A pump rate tells you solution volume per hour. To find the medication rate represented by that solution, multiply the verified concentration in mg/mL by the matching current rate in mL/hr. Convert mg/hr to mg/min only when the question asks for it.
Formula
medication rate (mg/hr) = concentration (mg/mL) × pump rate (mL/hr)
Use one verified concentration and its matching current mL/hr from the same infusion state. mg/hr and mL/hr describe different quantities.
Sample question
A practice solution is 2 mg/mL and the matching current rate is 15 mL/hr. What medication rate do those values represent?
2 mg/mL × 15 mL/hr = 30 mg/hr; 30 ÷ 60 = 0.5 mg/min
Answer: 30 mg/hr, or 0.5 mg/min
What these questions practise
- finding mg/mL from medication amount and solution volume
- calculating mg/hr from concentration and mL/hr
- converting mg/hr and mg/min
- keeping dose rate separate from pump volume rate
- stopping when concentration or current-rate information is missing 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.
