#### Answer

The patient should be given 2 tablets each day.

#### Work Step by Step

$1~lb \approx 0.45~kg$
We can convert 175 pounds to units of kilograms.
$175~lb = \frac{175~lb}{1}\times \frac{0.45~kg}{1~lb} = 78.75~kg$
We can find the total number of milligrams of the drug which should be administered daily.
$10~mg/kg\times 78.75~kg = 787.5~mg$
We can find the number of tablets which should be given to the patient each day.
$\frac{787.5~mg}{400~mg/tablet} = 1.97~tablets$
The patient should be given 2 tablets each day.
