Final answer:
Sally Whitney's total daily dose of Augmentin is approximately 654.5454 mg, and the dose to be administered every 8 hours is approximately 218 mg, after converting her weight from pounds to kilograms and using the prescribed 20 mg/kg/day dosage.
Step-by-step explanation:
To calculate the total daily dose of Augmentin for Sally Whitney, who weighs 72 pounds, and the dose to be given every 8 hours, we must first convert her weight to kilograms. Since there are 2.2 pounds in a kilogram, we divide 72 pounds by 2.2 to get her weight in kilograms:
72 / 2.2 = 32.727272 kilograms (approximately)
Next, we calculate the total daily dose using the ordered dosage of 20 mg/kg/day:
32.727272 kg * 20 mg/kg = 654.5454 mg/day
The total daily dose of Augmentin for Sally is approximately 654.5454 mg. Since the dose is to be divided and given every 8 hours, we need to divide this amount by 3, as there are 24 hours in a day:
654.5454 mg / 3 = 218.1818 mg
Therefore, the dose of Augmentin to be given to Sally every 8 hours is approximately 218 mg.
