Quizplus · Accepted Answer

We can use the given formula to calculate the amount of medicine the patient should receive in each dose:

Dose = (weight/20) x 150 mg

Substituting the given values:
Dose = (160/20) x 150 mg
Dose = 8 x 150 mg
Dose = 1200 mg

However, the question asks for the amount of medicine the patient should receive every 4 hours. We calculated the total daily dose above (1200 mg), so we need to divide this by the number of doses per day. Since the patient is receiving a dose every 4 hours, there are 24/4 = 6 doses per day.

Amount per dose = Total daily dose / Number of doses per day
Amount per dose = 1200 mg / 6
Amount per dose = 200 mg

Therefore, the patient should receive 200 mg of medicine in each dose. The answer is (D). The patient weighs 160 pounds, which is 8 times the 20 pounds used as the basis for the dosage. Therefore, the patient should receive 8 times the adult daily dosage, which is 8*150 = 1200 mg per day. 
Since the medicine is to be given every 4 hours, he will receive it 6 times a day (24 hours divided by 4 hours). 
Therefore, the amount he should receive in each dose is 1200 mg per day divided by 6 doses per day, which equals 200 mg per dose. 
So the answer is D, 200 mg.
