A nurse is preparing to administer dobutamine 2.5 mcg/kg/min by continuous IV infusion to a
client who weighs 65 kg. The amount available is dobutamine 250 mg/250 mL. The nurse should
set the IV pump to deliver how many mL/hr? Round to the nearest tenth. - ✔✔2.5 mcg/kg/min
65 kg
250 mg / 250 mL
how many ml/hr?
solve
2.5 x 65/1000 x 60 = 9.75 mg/hrX ml/hr = 9. x 250X = 9.75 ~~~~
9.8 ml/hr
A nurse is preparing to administer nitroprusside 4 mcg/kg/min by continuous IV infusion to a
client who weight 57 kg. Available is nitroprusside 50 mg in 250 mL dextrose 5% in water, D5W.
The nurse should set the IV pump to deliver how many mL/hr? round to the nearest tenth -
✔✔4 mcg/kg/min
57 kg
50 mg in 250 mL
how many mL/hr?
solve:
4/1000 x 57 x 60 = 13.68 mg/hrX mL/hr = 13.68 /50 x 250X =
