milliunits

1 Can anyone provide help with the following med math problem:
Client is admitted to labor and delivery for a trial induction.
Order reads: Begin Pitocin at 2 milliunits per minute and increase by 1 milliunit every 15 minutes until 3 good contractions every 10 minutes.
Available: 500 mL of normal saline with 30 units of Pitocin.
What rate (mL/hr) should be set on the infusion pump to begin the infusion?
Thanks......

Gahart and Adrienne R. Nazareno). Therefore. . .a 500 mL solution with 30 units of Pitocin in it will contain 60 milliunits of the Pitocin.Client is admitted to labor and delivery for a trial induction. Begin Pitocin at 2 milliunits per minute and increase by 1 milliunit every 15 minutes until 3 good contractions every 10 minutes. Available: 500 mL of normal saline with 30 units of Pitocin. What rate (mL/hr) should be set on the infusion pump to begin the infusion?Dose desired: 2 milliunits (mU)/minute
Dose on hand: 30 units/500 mL, or 60 mU/500 mL
500 mL/60 mU (dose on hand) x 2 mU/minute (dose desired) = 16.666 mL/minute, rounded off to 17 mL/minuteLast edit by Daytonite on Jan 22, '08aarohi likes this.

1 Unit = 1000 milliunits (mU)
dose desired: 2 milliunits/min
dose on hand: 30 units/500 mL or 60 milliunits/mL (this is the dose concentration)
so: dose desired x dose concentration
2 milliunits/min x ml/60 milliunits = 0.033 mL/min
set on the infusion pump? 0.033 mL/min x 60 min/hr = 1.9 mL/hr or 2 mL/hrkgh31386 likes this. 
0Aug 10, '09 by kgh31386, BSN, MSNYep, that's a good explanation. I did it just a tad bit differently, basically just cancel out the units. But I'm looking at daytonite's explanation, I was wondering if you could explain that, because we got totally different answers..unless I'm wrong, but I thought 1000mu were in 1u
2mu x 1u x __500ml x 60min = 2ml/hr
min `1000mu``30u ``1hrLast edit by kgh31386 on Aug 10, '09
