Question

A dog weighs 105lbs and is treated with thyroxine which is packaged in 0.8mg tablets. The dosage is 0.1mg/10lbs B. W. Once daily. The dog is to be treated for 3 days. How many tablets are necessary for each treatment?

Answer 1

`3.9375` tablets for 3 days of treatment.

Explanation:

Since dosage is 0.1 mg / 10 lbs, we need to divide the dog's mass by 10 and then multiply this number by 0.1 mg like so:

`(105 lbs)/(10lbs)=10.5`

`10.5*0.1mg=1.05` mg per day.

For 3 days, we need to multiply the daily dosage by 3;

`1.05mg*3=3.15mg`

To find the number of tablets necessary for the entire duration of the treatment, we can divide the total dosage by the dosage provided by each tablet;

`(3.15mg)/(0.8mg)=3.9375` tablets.
