Answer 1

Answer: C. 2,272 mg

Explanation:

Given : The recommended dose of a particular drug is 0.1 g/kg.

We know that 1 kilogram is equals to approximately 2.20 pounds.

Then ,
`\text{1 pound}=(1)/(2.20)\text{ kilogram}`

`\Rightarrow\text{50 pounds}=(1)/(2.20)*50\approx22.72text{ kilogram}`

Now, the dose of drug should be given to a 22.72 kilogram patient is given by :-

`22.72*0.1=2.272g`

Since 1 grams = 1000 milligrams

`2.272\text{ g}=2,272\text{ mg}`

Hence , 2,272 mg of the drug should be given to a 50 lb. patient.
