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.
