Is this correct?

If you're doing an IV rate then you will finish with ml/hr. From what you typed out, there has to be some info missing. Double check and see if maybe you left out some info.

Dopamine is usually dosed as "mcg/kg/min"...

So if dopamine is ordered 10mcg/kg/min and you want to find the mL/hr flow rate with what's available (Dopamine 300mg/350mL):

140lbs/2.2 = 64kg

So the dose will be 640mcg/min...you've got 300mg/350mL, so convert 300mg to mcg (300mg = 300000mcg)

300000mcg/350mL = 640mcg/XmL X= 0.75mL

0.75mL/1min = XmL/60min X=45mL/hr

Hey guys I checked the problem and the last sentence says what is the pump rate? So I just divide that by 24 hours?

Hey boogs what does the last sentence imply? Sorry I'm bad in math, so 0.75ml would be 1 min and 60mins?

10mcg=0.01mg

0.01 x 63.63 =0.6363 or 0.64mg

300mg = 0.64 mg

-------- -----------

350ml x mL

300x = 350 x 0.64

x= 0.746 or 0.75 mL

I tried to redo your computation. You need to write the entire question so we can help you.

Hope this helps.

0.75 mL per minute

45 mL per 60 minutes or every hour

1080 mL day or 24 hours

I used ratio and proportion to get all these answers.
