Answer:
3600 mg of drug per day.
![\text{The amount of drug per dosage}=\text{1200 mg}](https://img.qammunity.org/2020/formulas/mathematics/college/9aufh58ui7hyagopah5yqqw8y8pyjstvu4.png)
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.
![\text{The dosage of drug per day}=\frac{\text{60 mg}}{\text{ kg}}* 60\text{ kg}](https://img.qammunity.org/2020/formulas/mathematics/college/n83ocsawkxizbomzwlfidwrpicolkpx6xc.png)
![\text{The dosage of drug per day}=\text{60 mg}* 60](https://img.qammunity.org/2020/formulas/mathematics/college/i4tdnsdd4q5kd7sab7mlwqirwjkwmpqvuo.png)
![\text{The dosage of drug per day}=\text{3600 mg}](https://img.qammunity.org/2020/formulas/mathematics/college/xfruzw8o101r76zbj6jlqpop350d7kvuqc.png)
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.
![\text{The amount of drug per dosage}=\frac{\text{3600 mg}}{3}](https://img.qammunity.org/2020/formulas/mathematics/college/a2vhah5q4td4xorwgco1wri448az96vzk6.png)
![\text{The amount of drug per dosage}=\text{1200 mg}](https://img.qammunity.org/2020/formulas/mathematics/college/9aufh58ui7hyagopah5yqqw8y8pyjstvu4.png)
Therefore, the amount of drug per dosage would be 1200 mg.
