Calculate the maximum flow rate for this patient: ________.Ordered: dopamine: Begin infusion of 2 mcg/kg/min for bradycardia and systolic BP less than 90. Increase infusion up to 10 mcg/kg/min as needed.You have a premixed bag of dopamine with 200 mg in 500 mL of D5W. The patient weighs 185 lb.
Fill in the blank(s) with the appropriate word(s).
100.9 mL/h
Convert weight to kg:
1 kg : 2.2 lb = x : 185 lb
x = 84.09, rounded to 84.1 kg
Convert mg to mcg:
1,000 mcg : 1 mg = x : 250 mg
x = 1,000 mcg × 250
x = 250,000 mcg
Concentration of 
Calculate desired dose
D = 10 mcg/kg/min × 84.1 kg
D = 841 mcg/min
Determine dose per hour:
H = 500 mcg; Q = 1 mL; D = 50,460 mcg/h
A = 100.92, rounded to 100.9 mL/h
Step C flow rate or amount to administer is approximately 
of the dose on hand (500 mL) and 50,460 is approximately 
of the dose on hand so it is reasonable.
