Dosage calculation

Start by converting grams to milligrams then from milligrams to micrograms.

Where the heck did you get 24000mcg?

5 mcg * 80 kg * 60 minutes

iryna1983 · May 31, 2015

I think I got it. Please check it.

5*80*60

-----------

8000

and it equals 3 ml/ hr

8000 I got it from deviding 250by 2000000 mcg ( 2 g) .

Yes. And you also set the problem up in the format I typically use: (dose * weight * 60) / concentration.

Regarding your conversion error. You will need to be intimately comfortable with metric conversions: kg g mg mcg ng.

It's that easy to miscalculate, and a 1000 fold error (increase) would have tragic consequences.

You're welcome. Remember, you did this. All I did was ask you a few questions.

Great job! And I totally agree, YOU did this. You should be proud of yourself! This is why we don't spoon feed answers. Otherwise you wouldn't learn anything and you certainly wouldn't have the satisfaction of doing it yourself.

Where I've taught students were expected to learn to calculate dosages on their own, using a textbook/workbook that was very helpful. There wasn't a course for it. They were tested each semester on calculations and couldn't go on if they didn't pass by the third try each semester. There was a tutor who was very helpful. Tests in each course also included dosage calculations. Maybe this is your school's setup too?

I recommend the book "Math for Meds". Whether you are taught about the topic in class or not, you still need lots of practice. Now that school is out for the summer, maybe you can work your way through the book or any other resource. I think your school must have a resource for you.

My school's skills lab had packets with practice problems. Seems like your school should or does have something similar.

I used this site to practice before my calculation exams

Another thing is when you know how to set up problems, that will be a big help. First start with what is ordered. Put what the question is asking for at the end. Then plug in what you think will be needed to solve the problem. If all the units cancel out - you've set up the problem correctly and all you need to worry about after that is the math.

Doe Math for Meds show answers to all the problems? It never makes sense to me to do problems and not know if you're doing them correctly or not.

Whispera, MSN, RN · May 31, 2015

If memory serves, Math for Meds does show how to calculate answers. I just went to the book's website and see there's software that goes with it now. I was able to do a quiz and detailed answers were given. I think I can access the information because I was faculty, but I don't remember ever signing up for the site. Just in case you can use it too, here's the site address:

I recommend this book.(opps different book). I used maths and meds for nurses It takes you from the basic maths, walks you through how to convert units, and then how to apply that to drug doseage calculations
