Question

A 10 lb. cat needs 31⁄2 tablets that each contain 6 mg of a drug. what's the equivalent dose in mg/kg?

Answer 1

Mass of cat = 10 lb

1 lb = 0.454 kg

So mass of cat is 4.54 kg

Number of tablets given to cat

`N = 3(1)/(2)`

Each tablet has 6 mg of drug

Total drug given to cat

`Drug = 3(1)/(2) * 6mg`

`Drug = 21 mg`

Now dose given to cat in mg/kg form

`Dose = (mass of drug in mg)/(mass of cat in kg)`

`Dose = (21mg)/(4.54kg)`

`Dose = 4.63mg/kg`
