The nurse is initiating a prescription for 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.)

Infusion rate: 45 mL/hour Drop factor: Microdrip chamber For a microdrip chamber, the drop factor is typically 60 drops/mL. Calculate the microdrops/minute: Microdrops/minute = (Infusion rate in mL/hour × Drop factor) / 60 minutes Microdrops/minute = (45 mL/hour × 60 drops/mL) / 60 minutes Microdrops/minute = 45 drops/minute Therefore, the nurse should regulate the infusion at 45 microdrops/minute.
