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)
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.

This is what I got.
Question #1 Answer is 50 microgtt's/min
**Did I get it write?**
