Math question help please!

Try no rounding of anything until the end. I got 115.66613 mcg/day. So try 115.7 or 115.67.

115.60? If they really want it to the hundredth?
Also, please use the "quote" button so we know who you're responding to, when you say an answer is wrong.

Unfortunately not correct either, I'm baffled. Its a question on a case study and it is driving me bonkers that I can not get the correct answer.

That could be it. I seem to remember a similar issue with an ATI problem once that the only way to answer the question was divide the weight in pounds by the actual conversion amount of 1 kg = 2.20462262185 lb --- we get so used to simply using 2.2, but this can affect the answer.

yeah understand... is this a website that you could possible share the like to the problem, or is it a paid site or something provided by the school?

I am doing a math work sheet to help prepare for my upcoming semester in school and I need help with a math problem.
Question is....
The HCP prescribes 1.7 mcg/kg/body weight/day. Client's weight is 150 lbs.
What is the dose of medication ? ( round to nearest hundredth.)
I tried 115.91 and it is incorrect
150/2.2=68.18
68.18*1.7=115.91(rounded)
Can someone please show me how this problem is done.
Thank you!

Is this exactly how the question is written??

The body weight/day part is totally unnecessary and just sounds kinda weird.

Anyway, I think your math is right. Can't explain why the book doesn't agree.

When I worked in critical care where I had to calculate mcgs/ kg I used critical care drug calculation formulas that I had taped to the back of a small calculator at all times....What is the correct answer to this question if 115.6 is incorrect?

Are you 100% positive that the question is asking for how many mcg's per day? I see the question says "per dose." Is there no other information that says the drug is given BID or TID, etc. ?

The order is badly written as it doesn't say how many doses of the med are given per day.

OP i get the same answer you got and honestly speaking I never missed a math question since I've been in nursing school. so unless there's something else missing then the answer choices themselves must be wrong.

Did you try 115.90? I know that rule of rounding numbers when it's 5 or greater than 5, but I encountered some medical math problems like those numbers you described/posted.

Weird but true.

Where did this question come from? (Is it just an actual worksheet or an e-copy?) I'm in my 3rd semester of an ABSN program and I would have solved it the same way that you did, given the information that you had posted. We also never round until the end, so the weight in kg is kept in the long form until the end. However, even in this case, it resulted in the same answer. Now I'm curious as to what is missing or what the expected answer is supposed to be if all of the suggested answers are incorrect.
