Question

The drug labetalol has a dose of 300 mg and is administered in 300 mL of an intravenous infusion at a rate of 2 mg/min. Using an infusion set that delivers 20 drops/mL, calculate the required drip rate in drops/minute.

Answer 1

Step-by-step explanation:

From the given information:

Since 300 ml of intravenous infusion contains 300 mg of drugs;

Then; 1 ml of intravenous infusion contains (x) amount of drugs

(x) amount of drugs = (300 mg × 1 ml)/ 300 ml

(x) amount of drugs = 1 mg.ml

To calculate the drip rate in drops/minutes by applying conversion factors.

`rate (( in \ drops )/(minute ))= (2 \ mg )/(min ) * (20 \ drops)/(1 \ ml) * (1 \ ml )/(1 \ mg )`

`rate (( in \ drops )/(minute )) = 40 \ drops / min`
