IV question

Published

Hey everyone. I have a math homework problem that I can't seem to figure out. Any help is much appreciated.

You're working with an IV solution that contains 250 mg of dobutamine in 250 ml D5W. Your patient, who weighs 108 lbs (49 kg) is suppose to receive 6 mcg/kg/min. If the drip factor is 60 gtt/mL, how many microdrops per minute and how many milliliters per hour should be received?

What I have figured out is that the patient should receive 4.2 mL/hr. However, I cannot figure out the mcgtt/min.

I figured out that the patient is receiving 294 mcg/min. but i'm stuck as to what to do next....please help...thanks

yes it really does say mcgtt/min its sooo crazy...

Its 17 always round down the drops!

Well I'd say it's a typo and they meant to say drops/minute, but maybe there's something I've missed? You've got micro drip tubing there, and it's drip factor is 60 gtt/min. I did find a calculation for micro drops, but basically you would just move the decimal over, what, 6 places? So you'ld get some crazy number like 18,000,000 micro drips/min. Which is just ridiculous and not even applicable to nursing care. What would that number even mean? How would you apply it in practice?

This is homework right? Ask your instructor if they mean drops/min or micro drops/minute.

you guys rock....i have been trying to figure that out for 2 days always got stuck on the 294....and the way i first got the 4.2 is crazy but i just divided 60 into 250.....wrong way to do it but thats how i did it

I was taught differently; to round normally based on the first decimal point. But you should check with your instructor in order to get the question counted right in case they don't give partial credit.

In practice, the difference between 17 drops/min and 18 drops /min is 1 drop and in this case

Hello

Here is my math to get how many mcg / hr = 6mcg x 49 kg x 60 min= 17640mcg/hr or divid by 1000 to get 17.64 mg/hr

The ivpb is 1:1 so 17.64ml/hr set the pump (yes some pumps can go to the 100th

So to figure the gtt 17.64 divid by 60 = 0.294 ml/min x60gtt = back to the 17.64gtt then apply the rounding rules u were taught

18gtt/min
