Question

A 15 mg per 1 mL dosage is to be diluted to 40 mL. Run over 2 hr with a 20 mL flush. Determine the volume of solution which must be added to the Buretrol and the IV flow rate using a microdrip set.

Answer 1

A 15 mg per 1 mL dosage is to be diluted to 40 mL.

Here the drug available 1 ml, so we have to add 39 ml of dilutant to make it 40 ml.

It will run over 2 hr with a 20 mL flush.

That means we have to administer 20 ml in 2 hr with a micro drip set.

In micro drip set the drop factor = 60 gtt/ml

The formula for drop calculation = (Total volume in ml drop factor) time in Minute

=

=

Using a micro drip set we have to administer 10 drops per minute.
