Please Help!!!!!

Hi everyone! I am currently doing my pediatric clinical and I have a dosage calculation that is driving me crazy. I have clinical tomorrow and if I dont have this correct, my instructor will send me home with a zero! :crying2:

My patient is a 12 yr old with an INT IV in his left hand.

Here is what the order reads:

IV sodium chloride 0.9% 50 mL 100 mL/hr

Clindamycin 580 mg IV q 6 hours

I have already figured out my safe dose range and it is within safe range.

The recommended final concentraion is 18 mg/mL

The dilution calculation I came up with is 32 mL

According to my handbook, the drug should be infused over 10-60 minutes

HERES My questions I cant figure out.... 1. What rate will be set on the pump and 2. What volume will be set on the pump?

The normal saline part of the order has totally thrown me off!!!!! Please help!! Thank you so much!!!!

I am not clear: Are you reconstituting the Clidamycin in the 50 ml of NS or is it a separate bolus?

OK, if I am understanding this, You are reconstituting the Clindamycin from what is called a single-dose ADD-VANTAGE Vial which is already attached to the 50mLs of normal saline. There are drawings of what this system looks like on this page: http://www.drugs.com/pro/clindamycin-injection-usp.html. Assuming that, once you open the vial and the normal saline runs into the powdered Clindamycin, you have 18mg of Clindamycin/mL in 50 mL of normal saline. The normal saline is the diluent. So, as best I can reason this out. . .

580 mg (dose desired)/18 mg (dose on hand) x 1 mL (amount the dose on hand comes in - this is given information) = 32.22 mL, round to
32 mL
(total amount to give)

Then, What rate will be set on the pump? Pumps are always set at mLs/hour. If you want this 32 mLs to infuse over one hour then it will be
32mL/hour
. If you want it to infuse over 30 minutes, then you would set the pump at
64mL/hour
. If you want it to infuse over 10 minutes, then you would set the pump at
192mL/hour
.
