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 ["45"]
Explanation
Pump rate in mL/hour = Dose (mcg/kg/min) x Weight (kg) x 60 / Concentration (mcg/mL)
The concentration of nitroprusside is given as 50 mg in 250 mL of dextrose 5% in water.
Convert this to mcg/mL; multiply by 1000
Concentration (mcg/mL) = 50 mg x 1000 / 250 mL = 200 mcg/mL Therefore;
Pump rate in mL/hour = 2 mcg/kg/min x 75 kg x 60 / 200 mcg/mL Pump rate in mL/hour = 45 mL/hour
Therefore, the nurse should set the IV pump to deliver 45 mL/hour
Correct Answer is ["2"]
Explanation
Number of tablets = (Dose ordered / Dose available) x Frequency Number of tablets = (10 mg / 5 mg) x 1
Number of tablets = 2 x 1 Number of tablets = 2
