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 ["1"]
Explanation
Convert the client's weight from pounds to kilograms:
Weight (kg) = Weight (pounds) / 2.2 pounds/kg
= 176 pounds / 2.2 pounds/kg
= 80 kg
Calculate the prescribed dose in milligrams:
Dose (mg) = Prescribed dose (mg/kg) x Client's weight (kg)
= 0.05 mg/kg x 80 kg
= 4 mg
Calculate the volume to administer in mL:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 4 mg / 4 mg/mL
= 1 mL
Correct Answer is ["5.5"]
Explanation
Calculate the total volume to administer:
Total volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 55 mg / (100 mg / 20 mL)
= 55 mg / 5 mg/mL
= 11 mL
Infusion time in minutes = 2 minutes
Calculate the volume to administer per minute:
Volume per minute (mL/minute) = Total volume (mL) / Infusion time (minutes)
= 11 mL / 2 minutes
= 5.5 mL/minute
