What is the amount to be given every 8 hours

Answer 1

To calculate the total dose of Augmentin for Sally Brown, we need to follow these steps:

1. **Convert her weight from pounds to kilograms**:
- There are approximately 2.2 pounds in 1 kilogram.
- So, to convert 72 lbs to kg:
\[
\text{Weight in kg} = \frac{72 \text{ lbs}}{2.2 \text{ lbs/kg}} \approx 32.73 \text{ kg}
\]

2. **Calculate the total daily dose**:
- The physician ordered 20 mg/kg/day.
- So, the calculation will be:
\[
\text{Total daily dose} = 20 \text{ mg/kg} \times 32.73 \text{ kg} \approx 654.6 \text{ mg}
\]

3. **Total dose**:
- The total dose for Sally is approximately **654.6 mg** per day.

4. **Calculate the dose every 8 hours**:
- Since the total daily dose is to be divided into 3 doses (every 8 hours):
\[
\text{Dose every 8 hours} = \frac{654.6 \text{ mg}}{3} \approx 218.2 \text{ mg}
\]

5. **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**
