How do you THINK you should start?(Hint: this is not a homework hotline. It is important that you learn to solve problems for your own future nursing practice. Most responders would love to help you understand the question but would like to see you try to solve the problem first, then tell us where you're stumped.)

First convert your patient's weight from pounds to kgs. Start there, and then see if you can take it from there.

OK, I am not gonna give you any answers but I will help you figure out where to start. The rest is simple math..

1. Figure out the 300mg every 6 hours dose.. How many doses will that be in a 24 hour period.. What will the total mg be?

2. Convert the childs weight to kg.

3. do the math.. is the first part, your answer from #1 within that range..

The range is the lowest dose to the max dose a child of that size can have in a day..

Now show me your work and I will show you mine.. I did help you to start.

that's fine...i'm not asking for any answer only guidance and maybe i shouldnt have said i don't know where to start...i probably should've posted where i started and ask for guidance from there...this is what i came up with on where to start and wanted to know if i was heading in the right direction.

i know i must calculate the kilograms of a 40 pound child and then calculate the lower range of 120mg/x kg/day = ? then for the higher range of 150 mg/x kg/day =?

this is something i do want to learn to the fullest as i know this is what will be needed to properly medicate patients....you took the posting wrong or i posted wrong...whatever the case...thanks any way!:)

i'm so sorry...i'm new here...i should've posted what i came up with and then asked for guidance to see if i was headed in the right direction. but this is what i had came up with and just wanted to know if i was going in the right direction.

So you are on the right track.. What are the numbers you came up with.. what is the low range? what is the highest dose? Now what is the total mg of the med RX'ed? Does it fit in that range? Show me the numbers :)

This is what I came up with

40 lbs = 18.18 kg * 120 mg = 2181.6 mg

40 lbs = 18.18 kg * 150 mg = 2727 mg

24hrs/6 = 4 times a day

300mg * 4 = 1200 mg per day

my range is 2181.6 mg - 2727 mg

So I would say that the dose of 300 mg dose not fall in the range.

Am I right:confused:

That is what I have also. That dose is not therapeutic.
