Question

if 1 g of medication is to be delivered in100 ml over 1 hour, using a 10 drop set, what is the flow rate in gtt/min?

Explanation:

Step1: Convert hours to minutes

1 hour = 60 minutes

Step2: Use the flow - rate formula

The formula for flow rate (gtt/min) is $\text{Flow rate}=\frac{\text{Volume}(ml)\times\text{Drip factor}(gtt/ml)}{\text{Time}(min)}$. Here, the volume is 100 ml, the drip factor (for a 10 - drop set) is 10 gtt/ml, and the time is 60 minutes. So, $\text{Flow rate}=\frac{100\times10}{60}=\frac{1000}{60}=\frac{50}{3}\approx16.67$ gtt/min

Answer:

$\frac{50}{3}\text{ gtt/min}\approx16.67\text{ gtt/min}$
