Math question help please!

[Ashleyherberth]

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!

were you given the correct answer? How far off was your answer?

Me thinks that your answer sheet is in error.

[Ashleyherberth]

Sorry for the confusion but that's the answer I came up with and they said it's incorrect, I still

do not have the correct answer because I can not see the answer on the computer until I answer it correctly.

[Ashleyherberth]

Can you show me how to solve the problem please?

[Ashleyherberth]

No I do not have the correct answer that's what I'm searching for now.

I wonder if they're being picky about significant digits? Strictly speaking, you shouldn't be rounding to a hundredth of a kilo because you don't know what hundredth of a pound you have. Maybe try 150/2.2 = 68 kg, then 68*1.7 = 115.6?

uhmmmm - the only other possibilities that I could think of would be that the answer may be converting the units from mcg to mg... or maybe dividing the total into equal doses (tid, bid?) and the answer would be how much each dose should be.... and like someone else pointed out, the answer key could just be wrong.

[Ashleyherberth]

No not the correct answer either

[Ashleyherberth]

Its daily dose.

[203bravo, MSN, APRN]

Its daily dose.

yeah I understand that.. I'm just posting ideas to help you get past this question. you're math is correct....

115.60? If they really want it to the hundredth?
