Hello!~

relatively new around here, just needed some help with more math.., anywho..here's the problem:

300 cc Electrolyte 75 q6h is ordered for a child. At how many microdrops per minute should the IV be regulated...

so the formula i used was

rate= ml x gtt/ml

-----------

min

I got the 300 ml and using 60 gtt/ml since it says microdropper (not sure if that's correct..o well :imbar )

what I can't figure out is the mins...should I go by q6h? (so 360 min) or over 24h?? I'm used to seeing "give ____ over x hours):crying2:

here's another similar one:

Regulate the microdrops for a child when the dr. orders 50 ml per hour for 6 hours...dunno if I should put 60 mins or 360 mins

the solutions probably really simple, but my brain's on strike right now :uhoh21:

thanks!!~

Hiya dazed & confused ...

For the first problem: microdrips = 60 drops/minute - you're right about that. The problem is vague - saying to give 300ml q 6 h IS NOT the same as assuming that you give it OVER 6 hours. But let's assume ...

300ml x 60 gtt = 18000 / 360 minutes = 50 drops per min.

The second one: the key phrase is "50ml per hour" - total quantity or total # of hours doesn't matter.

50ml x 60 gtt = 300 / 60 min. = 50 drops per min.
