The nurse is initialing a prescription for IV dextrose 2.5% in 0.45% sodium chloride (Ds 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.)
The Correct Answer is ["45"]
(mL/hour) x (drop factor) / 60 = drops/minute.
The drop factor for a microdrip chamber is commonly 60 drops/mL.
Prescribed rate of 45 mL/hour, the calculation would be: (45 mL/hour) x (60 drops/mL) / 60 minutes/hour = 45 drops/minute.
