Question

Rx: abc drug 1 g in 500 ml of xxx to infuse 3 mg/min. what is the infusion rate in ml/min? please describe every step in detail. thanks

Answer 1

Available Abc Drug = 1gram or 1000 mg

XXX Infusion given= 500 ML

To calculate the millilitres/min. we first need to work out what dose is contained in one millilitre of the infusion dosage.

We can do this by dividing the volume of the dosage by the weight of the medicine it contains. In this case 500ml/1000mg = 1ml/2mg. Therefore, 1ml of this infusion solution contains 2mg of Drug Abc .

1ml contains 2mg Drug ABC so 0.5ml contains 1mg.

Then 3mg drug Abc contains 1.5ml infusion XXX.

we have to infuse 3mg/min.

So we can start the infusion at rate of 1.5ml/min that can deliver 3mg/min of Drug Abc in Infusion Abc.
