Question

Dobutamine 200mg in 250 mL of D5​ W is ordered to run at mcg/kg/minute. At how many mL/ hour will you set the pump

Answer 1

To calculate the mL/hour rate at which the Dobutamine should be set on the pump, you need to know the patient's weight, dosage in micrograms per minute, and the concentration of the Dobutamine solution. Once you have this information, you can convert the dosage to milligrams per hour and determine the mL/hour rate.

Step-by-step explanation:

To calculate the mL/hour rate at which the Dobutamine should be set on the pump, we need to convert mcg to mg.

Given that the order is to run at mcg/kg/minute, we need to know the patient's weight to determine the dosage in micrograms per minute. Once we have the dosage in micrograms per minute, we can convert it to milligrams per hour to determine the mL/hour rate.

For example, if the patient weighs 70 kilograms, and the Dobutamine dose is 5 mcg/kg/min, we can calculate the dosage as follows:

1. Convert the patient's weight to grams (70 kg * 1000 g/kg = 70000 g)
2. Calculate the total mcg/min dosage (70000 g * 5 mcg/kg/min = 350000 mcg/min)
3. Convert mcg to mg by dividing by 1000 (350000 mcg/min / 1000 = 350 mg/min)
4. Convert mg/min to mL/hour by dividing by the concentration of the Dobutamine solution. For example, if the concentration is 200 mg in 250 mL, the conversion would be (350 mg/min / 200 mg/250 mL = 437.5 mL/hour).
