Need help with math problem

Published

I am having problems solving the question. Here is the question I need help with.

Heparin 25,000 U in 250ml D5W is running through an administration set delivering 60 drops/ml. The flow rate required to deliver Heparin dose of 15 units/min is_________.

If some one could please explain how to solve. Thank you

I hope this helps. _250ml___ X _50u__ Cancel out the units (U) and all your left with is ml/min=

25000u min

250x50/25000=0.5ml/min

Then: _60gtt__ X _0.5ml___ 60x0.5= 30gtt/min

ml min

Sorry it came out a little weird. Write 250ml/25000u X 50u/min. Multiply 250 x 50 then divide that answer into 25000u. Which equals 0.5ml/min

Then 60gtt/ml x 0.5ml/min Multiply 60 x 0.5= 30gtt/min

Thank you for your help. Just one thing instead of the 50 it was 15, but no worries it still worked out when I did the math. I had the answer key. I just couldn't figure out how to get it. THank you again.:yeah:

heparin 25,000 u in 250ml d5w is running through an administration set delivering 60 drops/ml. the flow rate required to deliver heparin dose of 15 units/min is_________.

250 ml/25,000 units
(dose on hand)
x 15 units/minute
(dose desired)
x 60 gtts/ml
(drop factor of iv tubing)
=
9 gtts/minute
(drip rate)
