A 6 year old patient is being started on Keppra 35mg/kg/day in divided doses every 8 hours. She weighs 38lbs. the medication is available 20 mg/mL, how much would you give this patient? 

To determine the dosage of Keppra (levetiracetam) for a 6-year-old patient, we need to follow these steps:

1. **Convert the patient's weight from pounds to kilograms.**
2. **Calculate the total daily dosage in milligrams based on the prescribed mg/kg/day.**
3. **Divide the total daily dosage by the number of doses per day to get the dosage per administration.**
4. **Convert the dosage per administration from milligrams to milliliters using the medication concentration.**

### Step-by-Step Solution

1. **Convert the patient's weight from pounds to kilograms:**
   \[
   1 \text{ pound} \approx 0.453592 \text{ kilograms}
   \]
   \[
   38 \text{ lbs} \times 0.453592 \text{ kg/lb} \approx 17.24 \text{ kg}
   \]

2. **Calculate the total daily dosage in milligrams:**
   \[
   \text{Total daily dosage} = 35 \text{ mg/kg/day} \times 17.24 \text{ kg} \approx 603.4 \text{ mg/day}
   \]

3. **Divide the total daily dosage by the number of doses per day (every 8 hours means 3 times a day):**
   \[
   \text{Dosage per administration} = \frac{603.4 \text{ mg/day}}{3 \text{ doses/day}} \approx 201.13 \text{ mg/dose}
   \]

4. **Convert the dosage per administration from milligrams to milliliters:**
   \[
   \text{Concentration of medication} = 20 \text{ mg/mL}
   \]
   \[
   \text{Volume per administration} = \frac{201.13 \text{ mg}}{20 \text{ mg/mL}} \approx 10.06 \text{ mL}
   \]

### Conclusion

The patient should be given approximately **10.06 mL** of Keppra per dose, administered every 8 hours.
