Answer:
11.95 g / 6 hours
Step-by-step explanation:
drug dosage = 460 mg per kg per day
to be administered every 6 hours to a person who weighs 229 pounds
1 pound = 0.453592 kg
229 pounds = 229 × 1 pound = 229 × 0.453592 kg = 103.873 kg
dosage of drug needed for 103.873 kg
460 mg is to 1 kg per day
103.873 kg = 103.873 × 460 mg per 1 kg per day = 47781.58 mg per 103.873 kg per day
number of 6 hours in a day = 24 hours ÷ 6 hours = 4 times per day
dosage needed per 6 hours
47781.58 ÷ 4 = 11945.395 mg for every 6 hours = 11.95 g / 6 hours
