Nurseing Math Help.....

we don't give answers for homework here. learn your conversions from lb to kg and from mcg to mg.

If you're saying that the answer is 0.75 mL, that's correct. However, if you don't show how you got your answer, we're not able to help you.

Hello I try but I'm still getting the wrong answer....

we don't give answers for homework here. learn your conversions from lb to kg and from mcg to mg.

I know but I just need help

How are you setting up your problem?

22lbs is 10kg (2.2lbs per kg). With 15mcg/kg the amount of medication for the kid would be 150mcg or 0.150mg. If 1mg/5ml solution is available you use (1mg/5ml) x(0.150mg/x)=0.75ml of medication.

You have been asking dosage questions for years (circa 2011), what is the issue? I don't think nursing is your thing.

You need to break down the equation. The first step is to convert weight to KG. In peds patients, ALWAYS convert to KG, NOT pounds.

Pounds divided by 2.2. (

Then it is a "what you have" vs. "what you need" set up as fractions, cross multiply get rid of "x".

I am not even a "math person" and all of a sudden I can remember when it all clicked for me--cause I had to "talk it out" I find "x" annoying---HAHAHAHA!! Seriously, talk out the equation--everything has to be the same as far as ml, kg's.....print out a conversion chart....

And in real life nursing, always check your math and your dose with another nurse if you are calculating. Although usually pharmacy is relatively clear, and MD's in my neck of the woods are discouraged from doing a mg/kg dosage only, their orders need to have a specific dose. That doesn't mean you shouldn't check it though...

You have posted many ratio and proportion math problems. Even though you have been shown the formula, you are not absorbing it.

I think this is something you cannot learn by reading on a screen. Obtain a tutor through your school. A couple of one on one sessions in real life will do the trick.

Ok, step 1. You should be able to figure out that 22 lb is 10 kg in your head.

Step 2. 15 mcg/kg x 10 kg. Again, you can do this math in your head. Multiplying by 10 is taught in about the 3rd grade.

Step 3. 1 mg/5 mL. What does that mean? 0.2 mg/1 mL. From there, you can easily figure out how many mL = 0.15 mg or 150 mcg. Your answer is correct.

Yeah, as others are saying, I think 0.75mL is correct. And just FYI, it's 'nursing', not 'nurseing'. (I'm not making fun of anyone - English may not be your first language - just pointing it out).

Hi. What method are you using to solve this problem? Have you tried Dimensional Analysis? If not, look it up. Personally, I find that to be one of the best ways to solve the math problems.
