The healthcare provider (HCP) prescribes one litre of normal saline to infuse over 12 hours. The IV administration set delivers 20 gtt/mL. How many gtt/minute should the nurse regulate the infusion? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["28"]
Total volume to be infused = 1 litre
Convert the total volume from liters to milliliters:
Total volume (mL) = Total volume (liters) x 1000 mL/litre
= 1 litre x 1000 mL/litre
= 1000 mL
Drop factor of the IV administration set = 20 gtt/mL
Calculate the total number of drops to be infused:
Total drops = Total volume (mL) x Drop factor (gtt/mL)
= 1000 mL x 20 gtt/mL
= 20000 gtt
Calculate the infusion time in minutes and then the infusion rate in drops per minute:
Infusion time (minutes) = Infusion time (hours) x 60 minutes/hour
= 12 hours x 60 minutes/hour
= 720 minutes
Infusion rate (gtt/minute) = Total drops / Infusion time (minutes)
= 20000 gtt / 720 minutes
≈ 27.77 gtt/minute
Round to the nearest whole number:
Rounded infusion rate = 28 gtt/minute

Correct Answer is ["500"]
Explanation
Total volume to be infused = 250 mL
Convert the infusion time from minutes to hours:
Infusion time (hours) = Infusion time (minutes) / 60 minutes/hour
= 30 minutes / 60 minutes/hour
= 0.5 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)
= 250 mL / 0.5 hours
= 500 mL/hour
Correct Answer is ["125"]
Explanation
Total volume to be infused = 250 mL
Infusion time in hours = 2 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)
= 250 mL / 2 hours
= 125 mL/hour
