A medication is to infuse at 15 mcg/min. The solution available is 25 mg/100 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number & fill in the blank with the numerical value only)

Desired dose rate = 15 mcg/min Convert the desired dose rate to mg/hr: 1000 mcg = 1 mg and 60 minutes = 1 hour. Desired dose rate (mg/hr) = 15 mcg/min × (1 mg / 1000 mcg) × (60 min / 1 hr) = (15 × 60) / 1000 mg/hr = 900 / 1000 mg/hr = 0.9 mg/hr Available concentration = 25 mg / 100 mL Calculate the flow rate in mL/hr: Flow rate (mL/hr) = Desired dose rate (mg/hr) / Concentration (mg/mL) = 0.9 mg/hr / (25 mg / 100 mL) = 0.9 mg/hr / 0.25 mg/mL = 0.9 / 0.25 mL/hr = 3.6 mL/hr Round to the nearest whole number: = 4 mL/hr
