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

[petrit]

you are right is 5mg/1ml;

[petrit]

about the second questions not sure

[petrit]

The second question I think is 10mg/1mn=1000mg/xmn= 100min

And anybody else chime in here. Am I crazy? Have they constructed this question to come out with a really weird infusion time?...

No, not crazy, this is an unusual infusion time.

The second question I think is 10mg/1mn=1000mg/xmn= 100min

Yes, your infusion time would be 100 minutes.

You can use the same formula to calculate the infusion rate.

I just want to clarify the meaning of the questions

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

I'm sorry, I might have misunderstood which question you were referring to.

Regarding the minimum safe infusion time, you answered that question in this post.

The second question I think is 10mg/1mn=1000mg/xmn= 100min

Do you still need to calculate the infusion rate?

[petrit]

I just wanted to check with you the second part about the rate of the infusion.

rate = volume over hours= 200ml/100mn= 125ml is that correct

It's not what I got but very close. How did you calculate it?

And BTW, you're doing great. This is a process. It takes time to learn it. We want to take it slow with you so you really get the concept.

[petrit]

the way I done it is 100mn=1.6hr

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

[Wuzzie]

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

Okay, got it. You did it right. The difference is I rounded up to the tenth and used 1.7 which gave me 118. It depends on your school's rules for rounding. Do you understand the concepts of how you got your answers enough to be able to do it again?
