a client who weighs 176 pounds is receiving an iv infusion This is a topic that many people are looking for. cfiva.org is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, cfiva.org would like to introduce to you Dopamine Infusion ml/hr order mcg/kg/min on hand mg/ml dosage calculation weight base Part 1. Following along are instructions in the video below:
Guys today. Were going to answer. One of the dreaded problem in pharmacology calculating calculating medication with mikes per.
Kilogram per minute. And youre looking for as per hour or mls per hour. So.
Lets read. The problem order of infuse. Dopamine.
At 8 mikes per kilogram per minute on hand is dopamine mix 800 milligrams per 500. Ml or ccs of d5. Water and a patients weight is 198 pounds.
So how are we going to start with this problem. It says there. Calculate how many ccs per hour.
So before you start whenever youre starting to answer calculating medications you have to be concerned first. What are you looking for and this time youre looking for mls per hour. So this is what were going to do were going to label.
This one. A order infused dopamine at eight miles per. Kilogram per minute.
This is your doctors order. So were going to write here. Eight mikes okay per kilogram okay and then were going to put where were going to put minutes minutes is also a denominator so were going to put it below okay.
Now as so we know were looking for mls per hour. So we better cancel we could choose well. Where do we have to start first either.
We cancel mikes we cancel kilograms or we cancel minutes and for the purpose of this lesson. I think. Its better its easier for us to cancel minute first.
So that we could get our okay. So how many minutes are there in one hour. There there is what there are 60 minutes.
So if lets put 60 minutes. And then we have to put one hour here as our denominator. Why are we putting our as a denominator because thats what were looking for you see that ml is your numerator and our is your denominator so whenever youre doing a dimensional analysis you want to make sure that your ml is your numerator and you end up.
That your hour is your denominator. So lets cancel minute and minute. Okay now we have our as our denominator.
Okay and then after that we want to cancel micrograms. Okay. How are we going to cancel micrograms.
So canceling micrograms is easy because we have a gibbon in our on hand.
The our stuff on hand is dopamine mix with 800 milligrams. Over 500 ml. So.
500. Ccs of the five water. So why are we going to put so micrograms.
So one milligram okay. Were going to put milligram. As our numerator.
Because we wanna put the 1000 micro gram. As our denominator. Why so that we could able to we would be able to cancel micrograms as the dinner as the numerator there and as the numerator here or denominator.
Here now we were stuck with milligrams right and we have 800 milligrams and 500 ml. So are we going to put our ml. Okay.
Remember our ml is always what is always the numerator. So we have to put 500 ml here and we have to put milligram as our denominator and why are we doing that because of the milligram here okay so that we can cancel milligram so we want to put 800 milligrams. Here so in order for us to cancel milligram and thats the reason.
Why we put replace milligram as our denominator. So that we could cancel it against the new marina grande. Numerator.
So we cancel milligram and milligram.
And what were getting mls already. But were not yet done because we want to cancel kilogram and in order for us to do that we will we have to put one kilogram here okay so that we could cancel that but what is our what is our given pounds patient weight is 198 pounds. So we want to put 198 pounds here okay and 198.
Pounds is 1 kilogram is how many pounds 22. Pounds okay. So thats how you do it.
Now you want to cancel all of your variables. Now cancel kilograms and kilograms cancel pounds against pounds. So what you really have here right now are your numbers 865 hundred and 198 thats your numerator against your denominator that are what 1802 point.
2. Now you want to multiply everything. But multiplying everything would give you big big numbers so another technique that you want to learn or you want to use in your computation is to cancel all the zeros okay again and denominator against the numerator.
So lets count. All. The zeros 1 2.
3. Pay your numerator has 1 2. 3.
0. So lets cancel this 1 2. 3 one two three okay so were stuck with.
800 time is.
22 so 800 multiplied by 22. And that is equivalent to 1760. Okay.
Then dont forget to drag that hour and then we owned how many did we cancel. 3 right 1 2 3. Okay and then we want to kind of we wanna cancel.
We want to multiply 8 times 6 times 5 times. 1. And 8.
So 8. Time is 6 times. 5.
Times. 198. And this is equivalent to 40.
7520 again um. You want to cancel you want to go up against the denominator. Okay you want to go against the denominator.
So you want to cancel this 0. And 0. So you will youre left with 4752 divided by 176.
Which is what so youre getting what 27 mls per hour per hour. So thats your answer now. Theres another solution for this one and the other solution.
I will discuss it to you later .
