IV calculation NG losses

Published

Order: Replaced NG losses with 20KCL in 1L of R/L over 11.25 hours.

The patient on nights drained 500 ccs of NG losses. (ggt/min 10)

What is the rate of infusion in ggt/min and rate of infusion mls/ hr

I have no idea where to start.. help!

Read the problem, and then decide what exactly you are being asked. In this problem you have to identify three variables,

First, you need to determine a replacement volume for the patient's gastric losses. In practice, you would measure this at the end of the shift, but here you were provided this infotmation: 500 mL.

Second, you are to administer the 500 mL over 11.25 hours. With the information provided calculate the infusion rate in mL/hour. Solving this first will make it much easier to calculate the drip rate.

Last, to calculate the drip rate you need the hourly infusion rate, which you just calculated, and the drop factor. You have gtt/min 10, shouldn't this be 10 gtt/mL?

Is it not 1L over 11.25 hour? Are we just calculating the NG loss of 500ml?

If you are replacing the NG output, this is 500 mL. The order to replace the output with 20KCL in 1L of R/ L isn't telling you to use the entire liter, this is how the fluid is supplied.

When working this type of word problem you are usually provided much more information that you need. The first step is to determine what you are being asked to solve, and to extract only the data that you need.

500/11.25 = 44.44 ml/hour

(44.44 x 10) / 60 = 7ggt/min

Correct?

Thanks I was a bit confused with all the info provided.
