The Provider orders an IV weight-based medication to be infused at 4 mcg/kg/min. The patient weighs 198 lbs. You are supplied with a bag of the IV medication that reads 250mg/250 ml. How many mL/hr will you administer?
NOTE
- DO NOT write the unit/s of measurement
- DO NOT round your answer
The Correct Answer is ["21.6"]
Convert pounds to kilograms:
- 198 lbs / 2.2 lbs/kg = 90 kg
Calculate the medication dose in mcg/min:
- 90 kg 4 mcg/kg/min = 360 mcg/min
Convert mcg/min to mg/hr:
- 360 mcg/min 60 min/hr = 21600 mcg/hr
- 21600 mcg/hr / 1000 mcg/mg = 21.6 mg/hr
Determine the medication concentration:
- 250 mg / 250 mL = 1 mg/mL
Calculate the infusion rate in mL/hr:
- 21.6 mg/hr / 1 mg/mL = 21.6 mL/hr
