drug calculations help please

[petrit]

A patient is prescribed 1G of vancomycin.The drug has been reconstituted and diluted to a volume of 200ml.The maximum infusion rate of Vancomycin is 10mg/ml.

a) Whats is the minimum time over which the drug can be given safety

b) What rate would you set the infusion device to deliver this volume.

I will appreciate if anyone can help .

Kind regards

the way I done it is 100mn=1.6hr

rate= volume over time; 200ml/1.6hr= 125ml/hr

Using the following formula:

(volume to infuse / time to infuse (in minutes)) * 60

I get 120 mL/hour. While the formula that you calculated this works, if it were me I would have rounded the total time to infuse to 2 decimal places.

There are many formulae that can be used, find those that work for you. I have attached six formulae that I find work for me.

OP, I'm pretty sure most of us here are mystified why they would give a student a calculation with such an odd infusion time. As you can see there probably isn't a really hard answer. When faced with these kind of situations in real life we try to be as accurate as possible. Is 18ml/hr more accurate than 120ml/hr? No, it really doesn't make any difference at all. For you though, you need to find the parameters that your teacher wants you to use in order to be successful in the class. Hopefully we haven't confused you.
