Question

the prescribed dosage of a drug is 10 $\frac{mg}{kg}$ daily, meaning that 10 milligrams of the drug should be administered daily for each kilogram of a patients weight. how many 100 - milligram tablets should be given each day to a patient who weighs 164 pounds? (use the fact that 1 lb $approx$ 0.45 kg.)
the patient should receive 100 - milligram tablets each day.
(round to the nearest whole number as needed.)

Explanation:

Step1: Convert pounds to kilograms

Given 1 lb ≈ 0.45 kg, for a 164 - lb patient, the weight in kg is $164\times0.45 = 73.8$ kg.

Step2: Calculate the total daily dosage in mg

The dosage is 10 mg/kg, so for a 73.8 - kg patient, the total daily dosage is $10\times73.8=738$ mg.

Step3: Calculate the number of 100 - mg tablets

The number of 100 - mg tablets is $\frac{738}{100}=7.38$.
