A client receives a prescription for lactated Ringer’s 2 liters IV to be infused over 20 hours. How many mL should the nurse program the infusion pump to deliver? (Enter numerical value only.)
The Correct Answer is ["100"]
Calculation:
Convert the total volume from liters to milliliters:
Total volume (mL) = Total volume (liters) x 1000 mL/liter
= 2 liters x 1000 mL/liter
= 2000 mL
Total infusion time in hours = 20 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Total infusion time (hours)
= 2000 mL / 20 hours
= 100 mL/hour

Correct Answer is ["1"]
Explanation
Calculation:
Determine the concentration of the reconstituted solution:
Concentration (mg/mL) = Total amount of drug (mg) / Total volume after reconstitution (mL)
= 0.3 mg / 1.2 mL
= 0.25 mg/mL
Identify the prescribed dose = 0.25 mg
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
= 0.25 mg / 0.25 mg/mL
= 1 mL
Correct Answer is ["17"]
Explanation
Calculation:
Total volume to be infused = 150 mL
Infusion time in minutes = 90 minutes
Drop factor of the IV tubing = 10 drops/mL
Calculate the total number of drops to be infused:
Total drops = Total volume (mL) x Drop factor (drops/mL)
= 150 mL x 10 drops/mL
= 1500 drops
Calculate the infusion rate in drops per minute (drops/minute):
Infusion rate (drops/minute) = Total drops / Infusion time (minutes)
= 1500 drops / 90 minutes
≈ 16.67 drops/minute
Round to the nearest whole number:
= 17 drops/minute
