To calculate the total dose of Augmentin for Sally Brown, we need to follow these steps:
-
Convert her weight from pounds to kilograms:
- There are approximately 2.2 pounds in 1 kilogram.
- So, to convert 72 lbs to kg: \[ \text{Weight in kg} = \frac{72 \text{ lbs}}{2.2 \text{ lbs/kg}} \approx 32.73 \text{ kg} \]
-
Calculate the total daily dose:
- The physician ordered 20 mg/kg/day.
- So, the calculation will be: \[ \text{Total daily dose} = 20 \text{ mg/kg} \times 32.73 \text{ kg} \approx 654.6 \text{ mg} \]
-
Total dose:
- The total dose for Sally is approximately 654.6 mg per day.
-
Calculate the dose every 8 hours:
- Since the total daily dose is to be divided into 3 doses (every 8 hours): \[ \text{Dose every 8 hours} = \frac{654.6 \text{ mg}}{3} \approx 218.2 \text{ mg} \]
-
Result:
- Total dose: 654.6 mg/day
- Amount to be given every 8 hours: 218.2 mg
Thus, the answers are:
- Total dose: 654.6 mg
- Amount to be given every 8 hours: 218.2 mg
