How Do You Calculate IV Drip Rates for Medications?

[acehansen]

Homework Statement

Your patient weighs 70 kg the prescription states 0.5 mg/kg/hr. You have a bag of 250 mg in 50 mL. At what rate (mL/hr) will you set the pump?

Homework Equations

I don't think I have to convert the units of this equation, just cancel them out... but I'm not entirely sure.

The Attempt at a Solution

I tested it out, this is how i answered it
0.5/mg/kg/hr X 70kg = 35mg/hr

35 mg/hr X 50ml/250mg (I cancel out mg)
= 7ml/hr

I am not sure if I did this correctly.

How many milligrams per hour does the whole of the patient need ?
35 mg/hr is fine.
you know 250 mg is 50 ml, so 35 mg /hr is 35/250 * 50 mg/hr * ml/mg
You and patient can rest assured that this is correct.

Welcome to PF :) (though this is more like artihmetic, isn't it ?)
