Final answer:
To convert the dosage from mg/kg to the total daily dosage calculation in milligrams for Mrs. Monroe, first convert her weight from pounds to kilograms. Then, multiply this value by the per kilogram dosage and the number of doses per day. The answer is approximately D) 120 mg.
Explanation:
The subject of this question is mathematics, specifically it deals with the concept of unit conversion and multiplication. Here, we have Mrs. Monroe's weight in pounds (165 lb) but the medication dosage is given in milligrams per kilograms (0.8 mg/kg). So first we need to convert Mrs. Monroe's weight from pounds to kilograms. We know that 1 lb is approximately 0.4536 kg. So, Mrs. Monroe's weight in kilograms is 165 lb * 0.4536 kg/lb = 74.85 kg.
Next, we need to find out how many milligrams of the medicine Mrs. Monroe should take. The dose is 0.8 mg for each kilogram of bodyweight. So, Mrs. Monroe's daily dose of the medicine would be 74.85 kg * 0.8mg/kg = 59.88 mg. However, it's given in 2 divided doses, so the total is multiplied by 2, giving us 119.76 mg per day. By rounding to the nearest whole number, this would be approximately 120 mg per day. Thus, the correct option is D) 120 mg.
