Your 110 kg patient has dopamine 500 mg/250 ml running at 55 ml/hour. How many mcg/kg/min is the patient receiving? Round to the nearest whole number.
17 mcg/kg/min
(500 mg/250 ml = 2 mg/ml

63 minutes
Order is for dobutamine 2.5 mcg/kg/min. Patient weighs 88 lbs. Dobutamine 500 mg/250 ml is available. Round to the nearest whole number.
a) How many mcg/min should the patient receive?
b) What is the IV pump rate in ml/hr?
a) 100 mcg/min
(88/2.2 = 40 kg x 2.5 = 100)
b) 3 ml/hour
(100 mcg/ 1000 = 0.1 mg/min x 60 = 6mg/1hr
500 mg/250 ml = 2 mg/ml
6mg/2 mg x 1 ml = 3 ml/hour
Order is for linezolid 10 mg/kg infused over 90 minutes, every 8 hours for 14 days. Patient weighs 99 lbs. Linezolid 600 mg/300 ml is available. Round to the nearest whole number.
a) How many mg is the patient receiving per dose?
b) What is the IV pump rate in ml/hr?
c) How many mg is the patient receiving per day?
a) 450 mg/dose
b) 150 ml/hr
450 mg/600 mg x 300 ml = 225 mg in 90 min
225 mg / 90 x 60 = 150 ml
c) 1350 mg/day
