Dosage Calculations

I have another one:

A.
The order is IVPB 500 mL 0.9% sodium chloride with 20 units of pitocin to be infused at a rate of 4 mU per minute. Calculate the flow rate in microdrops per minute:

60 gtt/mL X 500 mL/ 20 units X 1 unit/ 1000 mU X 4 mU/ minute = ???


B.
The order has been increased to 7 mU/min. Recalculate the flow rate in microdrops per minute.

60 gtt/mL X 500 mL/ 20 units X 1 unit/ 1000 mU X 7 mU/ minute = ???



Thanks!!!!!!

Thank you very much for your reponse!!! As you can see I have spent all day studying for my math final in addition to chem, psych and english. By the time this week is over I will have my eyes stuck behind my head but I understand this is the most important class (right now)

Here is another one.......sorry to be a pain in the A--.

Magnesium sulfate 4 g IV push, loading dose Vial reads 25%. Follow with 250 mL D/5/W with one vial of 25% magnesium sulfate, infuse at a rate of 1 gram per hour

a. How many milliliters contain the loading dose?

Don't see that information recorded anwhere in the question???


b. Calculate the flow rate in millilters per hour for the D/5/W infusion

The 250 mL D5W has one vial of 25% mag sulfate, which is 4 grams.
250 mL/ 4 g X 1 g/ hr =

250/4 = 62.5 mL/ hr



Thanks,
