Question 9 :
The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D5 0.5% NS) 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.)
Correct Answer: ["45 microdrops\/minute"]
- Calculate the hourly volume in mL: 45 mL/hour
- Convert the hourly volume to minute volume: 45 mL/hour ÷ 60 minutes/hour = 0.75 mL/minute
- Multiply the minute volume by the drop factor: 0.75 mL/minute x 60 microdrops/mL = 45 microdrops/minute
- The nurse should regulate the infusion at 45 microdrops/minute
