The prescribed dosage of a drug is 10 milligrams per kilogram of a patient's weight daily. How many 200-milligram tablets should be given each day to a patient who weighs 169 pounds? (Use the fact that 1 lb ≈ 0.45 kg.)

The patient should receive ______ 200-milligram tablets each day. (Round to the nearest whole number as needed.)

To determine the number of 200-milligram tablets that should be given daily to a patient who weighs 169 pounds, we need to convert the weight from pounds to kilograms and then calculate the dosage based on the prescribed dosage of 10 milligrams per kilogram of body weight.

Given that 1 pound is approximately equal to 0.45 kilograms, we convert the weight of the patient, which is 169 pounds, to kilograms by multiplying it by 0.45. Thus, the weight of the patient is approximately 76.05 kilograms.

Next, we calculate the total dosage by multiplying the weight of the patient in kilograms by the prescribed dosage of 10 milligrams per kilogram. Therefore, the total dosage is approximately 760.5 milligrams.

To find the number of 200-milligram tablets needed, we divide the total dosage by the dosage per tablet. Hence, the number of tablets required daily is approximately 4 tablets.

In conclusion, a patient who weighs 169 pounds should receive approximately 4 200-milligram tablets each day according to the prescribed dosage of 10 milligrams per kilogram of body weight.
