Med question

Published

Just trying to practice medication calculations with a friend -

Here's my question

You need to give a 17kg child 15mg/kg of Tylenol liquid form. The Tylenol you have on hand is 240mg/2.4mL. How much Tylenol do you give?

You have a 92 lb child who needs 0.3mg/kg of Midazolam. You have 5mg/2.5mL Midazolam on hand. How much Midaz do you give?

THANKS!

I once precepted a nurse completely incapable of med calculations. People here are very helpful if you are stuck on a particular problem, but show your work... this is, what, a quiz? For us? No thanks.

Please show us some of your work/thoughts. How will you set up the problem? What do you think the answer is and how are you arriving at that conclusion?

I passed my med tests in college, and I now perform them every day. I could easily solve these for you, but giving you the answer would not teach you anything. I'll be happy to correct your work or show you where you went wrong, but first I need to see that you're actually trying.

woah woah, these were just some practice examples. no quiz or anything. just wanted some verification. i guess i'll make that more clear next time....

the first one i got 2.55mL

17kgx15mg = 255mg

255mg/240mg = 1.0625

1.0625x2.4mL = 2.55mL

next i got about 6.27 mL

92lbs/2.2 = 41.81kg

41.81kgx0.3mg = 12.54mg

12.54mg/5mg = 2.5

2.5x2.5mL = 6.27mL

You have the right answer on both questions. On the 2nd one, I rounded the weight to 42kg and got 6.3 ml for my answer. When it comes to peds it is always a great idea to have someone double check you math.

when in doubt ask... If something just doesn't seem right.. ask...

good luck!

Here are some really good sites. You have the answers correct but in working with peds, I agree, always have someone check your work...it's just safer that way..
