stumped on dosage calc..ahhhhhhh

[BarbiWatts]

Hello,I need help I have a answer but after over of 100 practice questions to make myself better this one has got on my last nerve, I'm sure its easy and maybe I should walk away after 9 hours of this but I need some logic to this one...

The client's heparin drip is ordered to be increased to 2200 units/hour. The heparin drip of 250 ml D5W with 25,000 units of heparin is currently infusing at 1800 units/hour. At how many ml/hour will the heparin drip now infuse?

I know its 22mL/hr but no matter how I set it up a noooooo. please help

There's extra information in the question that you don't need to calculate it. How are you setting it up?

increased to 2200 units/hour. The heparin drip of 250 ml D5W with 25,000 units of heparin is currently infusing at 1800 units/hour.*At how many*ml/hour*will the heparin drip now infuse?*

I know its 22mL/hr but no matter how I set it up*

25,000 units/250 mL=100 units/ml

Desired dose of 2,200 units/hr ÷ 100 unit/mL=22 mL

I set up every way but did not know I needed a answer to input to the next part....yeah I so happy

[BarbiWatts]

Thank you for showing me the way to set up and why.... I have been doing everything except using the answer to continue to the next part of solving it ....I'm so grateful .......

Another way to solve it is:

250ml/25,000 units X 2,200 units = 22 ml

Dimensional analysis.
