Maths someone help

Hi all i am desperately in need of help

Can someone explain to me how to do this please so confused...

The doctor orders a child ibuprofen 10mg/kg every 6 hours for relief of pain.How many ml of ibuprofen 100mg/5ml will you administer.

How do you do this

and also

The doctor orders amoxycillin trihydrate 75 mg/potassium clavulanate 18.75 mg PO b.d. for an urinary tract infection (UTI). The pharmacy dispenses amoxicillin 125mg/clavulanate 31.25 mg per 5 mL as Augmentin suspension. How many mL will you instruct the child's parent to administer?

Any help is appreciated

Thankyou

the first one you dont have all needed info, or at least you didnt share it.....the second one would have to be clarified with the doc, because as you have transcribed they are not equivalent drugs...good luck

That was actually the whole question and we are suppose to calculate it and i'm not sure how to do it.

The supposed answer for the first question is 16ml but i don't know how to get to that answer

And the second ones answer is 3ml but i don't know how to get that answer either...

use your critical thinking skills....if you are going to give a child a med by WEIGHT, what is missing out of that information???????

the second one, if you go on the basis of the amoxil...my ans is 3ml.....so ya got me

the child is 32kg sorry i guess i forgot to add the most important bit lol

As for the second one i cant really change the question as thats how it is but

Thanks for trying anyway :)

ok.....i see we act agree on the second one.....

the first one is missing the weight of the child.......you CANT NOT determine the answer without that......

0.5ml/kg : x/wt of child....since you know the answer you can work it backwards......but, as written it is NOT possible to do.....

the second one is 125/5 : 75/x......125x=375.....

the doctor orders a child ibuprofen 10mg/kg every 6 hours for relief of pain for a child who weighs 32 kg. how many ml of ibuprofen 100mg/5ml will you administer?

10 mg/1 kg

(dose desired)

x 32 kg

(weight of child) x

5 ml/100 mg

(dose on hand)

=

16 ml

(amount to give per one dose)

the doctor orders amoxycillin trihydrate 75 mg/potassium clavulanate 18.75 mg po b.i.d. for an urinary tract infection (uti). the pharmacy dispenses amoxicillin 125mg/clavulanate 31.25 mg per 5 ml as augmentin suspension. how many ml will you instruct the child's parent to administer?

if you look closely you should recognize that although the amoxicillin sent by the pharmacy is not the same strength ordered it is the same by ratio equivalent:

75mg/18.75mg = 125mg/31.25mg

75mg amoxicillin/18.75 clavulanate =

x

mg amoxicillin/31.25 mg clavulanate,

x

= 125 mg amoxicillin

then, you only need to work with one of the drug figures in the mixture:

75 mg of amoxicillin

(dose desired

)/125 mg of amoxicillin

(dose on hand)

x 5 ml

(amount the dose on hand comes in)

=

3 ml

(amount you instruct the child's parent to administer)

where do you see a wt?
