A 100 lb patient needs 15 mg/kg/day of amoxicillin for seven days. In total, how much amoxicillin will be administered to the patient during this period of time? A. 47.72 mg B. 4,772 mg C. 4.76 mg D. 476 mg

First convert the patients weight from lbs to kg

Look up (google lbs to kg) 100 lbs = 45.4 kg person

If this person gets 15 mg amoxicillin per 1 kg body weight

45.4 kg * 15 mg = 681 mg per day

times 7 days = 4,767 mg

Closest answer you have listed is B. It may be off a little depending on the lbs to kg conversion and rounding weight.
