A nurse is preparing to administer dopamine 5 mcg/kg/min via continuous IV infusion to a newborn who weighs 4.4 kg and has septic shock. Available in dopamine 200 mg in dextrose 5% in water 250 mL. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.7"]
The dose of dopamine in mg/hr: 5 mcg/kg/min x 4.4 kg x 60 min/hr = 1320 mcg/hr Converted to mg: 1320 mcg/hr / 1000 mcg/mg = 1.32 mg/hr
Infusion rate in mL/hr: 1.32 mg/hr / (200 mg/250 mL) = 1.65 mL/hr Rounded off to the nearest tenth: 1.7 mL/hr

Correct Answer is ["3.5"]
Explanation
1000g=1kg 3500g=3500*1/1000
=3.5kg
Correct Answer is ["2.9"]
Explanation
Let’s calculate the IV pump rate for administering dobutamine to a preterm newborn.
Step 1 is to convert the dose from mcg/kg/min to mg/kg/min. We know that 1 mg = 1000 mcg, so we have:
12 mcg/kg/min ÷ 1000 = 0.012 mg/kg/min
Step 2 is to calculate the total amount of dobutamine the newborn needs per minute:
0.012 mg/kg/min × 2 kg = 0.024 mg/min
Step 3 is to convert this to an hourly rate:
0.024 mg/min × 60 min/hr = 1.44 mg/hr
Step 4 is to calculate the volume of the solution that contains this amount of dobutamine. We know that 250 mg of dobutamine is dissolved in 500 mL of solution, so:
(1.44 mg/hr ÷ 250 mg) × 500 mL = 2.88 mL/hr
So, the nurse should set the IV pump to deliver approximately 2.9 mL/hr (rounded to the nearest tenth).
