Answer:
3600 mg of drug per day.

Explanation:
We have been given that a patient is ordered 60 mg/kg/day of an antibiotic.
Since the weight of the patient is 60 kg, so the dosage of drug per day would be 60 mg times 60.



Therefore, the patient should receive 3600 mg of drug per day.
Since the patient gets 3 doses per day, so dosage of drug per dosage would be amount of drug per day divided by 3.


Therefore, the amount of drug per dosage would be 1200 mg.
