Correct Answer is ["1.7"]
Explanation
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 ["1.8"]
Explanation
Dose = Desired dose / Available dose x Volume Therefore;
Dose = (56 mg / 160 mg) x 5 mL Therefore;
Dose = 0.35 x 5 mL Dose = 1.75 mL
Round to the nearest tenth: Dose = 1.8 mL
The nurse should administer 1.8 mL
