Dosage Calculations
Dosage Calculations ( 10 Questions)
A nurse needs to administer an IV infusion at a rate of 125mL/hr. How many drops per minute should be delivered if the drop factor of the tubing set is 15gtt/mL?
To calculate drops per minute, the nurse should multiply the infusion rate in mL/hr by the drop factor in gtt/mL and divide by 60min/hr. In this case, the infusion rate is 125mL/hr and the drop factor is 15gtt/mL so, the nurse should deliver(125mL/hrx15gtt/mL)/60min/hr=31gtt/min.
