Need help with calculating drops/minute

[sam0931]

Hi guys. I've only started nursing this year. We haven't started drug calculation yet but I've been trying to do some anyways to prepare myself. I've come across this problem:

IV Ceftriaxone 1000mg is to be diluted with sodium chloride with total volume of 100mls. This is to beadministered over 30 minutes via Micro giving set. Calculate the drops/minute?

so should the calculation be like this:

1100 x 60 (micro)

30 minutes

=

??

Thanks guys

If you meant

"100cc (NOT 1100cc!!) x 60gtt/cc

____

30 minutes "

You're correct.

You could think of this without too much work by realizing that with microgtt (60gtts/cc) tubing, gtts/min = cc/hr. Always.

100 cc to give in 1/2 an hour = 200 cc in one hour, therefore 200 microgtts/min.

Not 1100 x 60. You only use the volume when calculating the rate in drops per minute or mL/hr. You don't add the dose in mg to the volume. The volume is 100 mL.

Yes, they always throw in the dosage to put you in a quandry...learning to take out what you don't need and concentrate on what you do need it the key to med math.
