drops per minute

Nursing Students Student Assist

Published

I am looking for someone to help me figure this out. I have a whole worksheet to practice (we are getting tested our first day of school and need 100%) and I cannot find anything in my text or on the web. Can someone just show me how to set the 1st problem up and then I can figure out the rest? Please? The question is:

Determine the following in drops per minute using the drop factor provided.

3000mL D5W at 125 mL/hr

a. 10 gtt/mL

I appreciate anyone showing me how to set this up and then I can work the rest. :bow:

Hello Momandstudent,

Are you saying that a. 10 gtt/ml is your answer or the drip factor?

Thanks,

125 ml/1 hour
(infusion rate)
x 1 hour/60 minutes
(conversion factor)
x 10 gtts/ml
(drop factor of iv tubing being used)
= 20.833 gtts/minute
, rounded off to
21 gtts/minute
(drip rate)

It was the drip factor. Thank you.

Thank you for the help. So can I ask if I did this one right? Question is:

Determine the following in drops per minute using the drop factor provided.

2500 mL R/L in 12 hr.

a. 10 gtt/mL

2500/1 X 1/720 X 10 =34.72 which would round to 35

What does the R/L stand for?

Another thing: do you always round up to the next whole number or do you round down if it is

R/L stands for Ringer's Lactate. It is also abbreviated as LR which stands for Lactated Ringer's.

The rules of rounding are as follows:

  • If the number to be rounded is less than 5, drop it and all the figures to the right of it.
  • If the number to be rounded is more than 5, increase by 1 the number to be rounded, that is, the preceding figure.
  • If the number to be rounded is 5, round the number so that it will be even. Keep in mind that zero is considered to be even when rounding off.
