Question

An IV is infusing at 62.5​ mL/h. If the drop factor is 10​

gtt/mL, what would this rate of flow equal in​ gtt/min?

Answer 1

To calculate the IV infusion rate in gtt/min, multiply the infusion rate (62.5 mL/h) by the drop factor (10 gtt/mL), then divide the result by 60. The IV is infusing at a rate of approximately 10.417 gtt/min.

Step-by-step explanation:

The question asks how to convert the rate of IV fluid infusion from mL/h to drops per minute (gtt/min) given a drop factor. To find the flow rate in gtt/min, you need to use the following calculation:

• Multiply the infusion rate (62.5 mL/hour) by the drop factor (10 gtt/mL).
• Convert the resulting number from gtt/hour to gtt/min by dividing by 60 (since there are 60 minutes in an hour).

So, the calculation would look like this:

(62.5 mL/h) × (10 gtt/mL) = 625 gtt/h

Then convert to gtt/min:

625 gtt/h ÷ 60 min/h = 10.417 gtt/min

Therefore, the IV is infusing at a rate of approximately 10.417 gtt/min.
