Question

An IV is to run at 25mL per hour. The drop factor of the infusion set is 10gtt/mL. What is the flow rate? Round your answer to the nearest whole number.

Answer 1

The flow rate is 4 gtt/min

Step-by-step explanation

Given information

The drop factor of the infusion set = 10 gtt/mL

The volume per hour = 25mL per hour

Let the volume flow rate be x

To find the volume flow rate, we will need to use the below formula

`Flow\text{ rate = }\frac{Volume\text{ \lparen mL\rparen}}{min}\text{ }*\text{ Drop factor}`

The next step is to convert the volume per hour to volume per minutest by dividing 25mL by 60

`\begin{gathered} Volume\text{ per min = }(25)/(60) \\ Volume\text{ per min = 0.41667 mL/min} \end{gathered}`

The next step is to substitute the given data into the formula above

`\begin{gathered} Flow\text{ rate = 0.41667}*\text{ 10} \\ Flow\text{ rate = 4.16} \\ To\text{ the nearest whole number} \\ Flow\text{ rate}\approx\text{ 4gtt/min} \end{gathered}`

Hence, the flow rate is 4 gtt/min
