The client is receiving 4 mcg/kg/minute. The given values are:
weight of client = 64 kg
dopamine concentration = 1.6 mg/ mL
And we are asked to find at what rate to set the IV pump. This can be calculated using the formula:
rate= (4 mcg/kg/minute)*(weight of client)/(dopamine concentration)
Substituting the known values:
rate= (4 mcg/kg/minute)*(64 kg) / (1.6 mg/mL)
We know that 1 mg = 1000 mcg
So, 1.6 mg = 1600 mcg
Therefore:
rate = (4mcg/kg/minute)*(64 kg) / (1600 mcg/ mL)
We get:
rate = 0.16 mL/min
