The nurse is initiating a prescription for 0.9% Normal saline at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["45"]
Infusion rate in mL/hour = 45 mL/hour
Microdrip drop factor = 60 microdrops/mL
Calculate the infusion rate in microdrops per minute:
Infusion rate (microdrops/minute) = Infusion rate (mL/hour) x Microdrip drop factor (microdrops/mL) / 60 minutes/hour
= 45 mL/hour x 60 microdrops/mL / 60 minutes/hour
= 45 microdrops/minute

Correct Answer is ["1"]
Explanation
Desired dose = 2 mg
Available concentration after reconstitution = 2 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 2 mg / 2 mg/mL
= 1 mL
Correct Answer is ["83"]
Explanation
Total volume to be infused = 1000 mL
Total infusion time in hours = 12 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Total infusion time (hours)
= 1000 mL / 12 hours
≈ 83.33 mL/hour
Round to the nearest whole number:
Rounded infusion rate = 83 mL/hour
