First, let's calculate the patient's weight in kilograms:
221 pounds×1 kg/2.2 pounds = 100.45 kg
The daily medication dose required based on the patient's weight is:
21 mg/kg×100.45 kg = 2109.45 mg
Now, this total daily dose needs to be divided into three equal doses for each meal. Therefore, let's find the dosage per meal:
2109.45 mg÷3=703.15 mg≈703 mg (rounded to the nearest whole number)
The medication comes in 175 mg tablets. To determine how many tablets should be taken at each meal:
703 mg per meal÷175 mg per tablet=4 tablets per meal
Therefore, the patient should take 4 tablets at each of the three meals to achieve the required dose. Therefore, the correct answer is D. 4 tablets per dose.
