A neonate weighing 2.4 kg is receiving nitroglycerin at 0.2 mcg/kg/min. What is the infusion rate in micrograms per minute?

A neonate weighing 2.4 kg is receiving nitroglycerin at 0.2 mcg/kg/min. What is the infusion rate in micrograms per minute?

• A. 0.048 mcg/min
• B. 0.48 mcg/min
• C. 4.8 mcg/min
• D. 0.0048 mcg/min

Answer: (B)

Infusion rate in micrograms per minute equals the patient’s weight in kilograms multiplied by the dose in micrograms per kilogram per minute. Here, 2.4 kg × 0.2 mcg/kg/min = 0.48 mcg/min. So the neonate should receive 0.48 micrograms each minute. This result makes sense because you’re applying the per-kilogram dose directly to the patient’s weight, keeping the units consistent (micrograms per minute). The other numbers would come from incorrect decimal placement or mixing up weight or dose, which doesn’t fit the given information.
