Calculation
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.)
microdrops/minute
Explanation & Rationale
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
