Question

if 500 ml at 30 gtt/min is administered using a 10 drop set. what is the flow rate in ml/h?

Explanation:

Step1: Determine drops per hour

Since there are 30 drops per minute (gtt/min) and 60 minutes in an hour, the number of drops per hour is $30\times60 = 1800$ gtt/h.

Step2: Convert drops to mL

A 10 - drop set means that 10 drops equal 1 mL. Let the volume in mL per hour be $x$. We can set up a proportion $\frac{1}{10}=\frac{x}{1800}$. Cross - multiplying gives $10x = 1800$, so $x=\frac{1800}{10}=180$ mL/h.

Answer:

180 mL/h
