Ordered: Dobutamine 500 mg in 250 mL to infuse at 75 mg/h for a patient weighing 176 lb. The maximum safe dosage of dobutamine is 40 mcg/kg/min. If this is a safe dose, calculate the flow rate: ________. If the ordered dose is not a safe dose, write: not safe.
Fill in the blank(s) with the appropriate word(s).
37.5 mL/h
Convert weight to kg:
1 kg : 2.2 lb = x : 176 lb
x = 175 kg/2.2 = 80 kg
Convert mcg to mg:
1 mg: 1,000 mcg = x : 40 mcg
x = 0.04 mg
Calculate mg/kg/min (desired dose):
D = 3.2 mg/min
Determine maximum safe dose per hour:
Maximum safe dose is 192 mg/h, so 75 mg/h is a safe dose.
Calculate the flow rate:
A = 37.5 mL/h
