1. Convert the weight of the child to pounds. Since 1 ounce is equal to 1/16 of a pound, the weight of the child is:

30

lb

+

4

16

lb

=

30.25

lb

30 lb+

16

4

lb=30.25 lb

2. Calculate the recommended dosage for the child based on their weight:

Dosage

=

3.2

mg/lb/day

×

30.25

lb

=

96.8

mg/day

Dosage=3.2 mg/lb/day×30.25 lb=96.8 mg/day

3. Convert the recommended dosage from milligrams to milliliters using the concentration of Furadantin:

Dosage in mL

=

96.8

mg

5

mg/mL

=

19.36

mL

Dosage in mL=

5 mg/mL

96.8 mg

=19.36 mL

4. Divide the total daily dosage by the number of doses per day (qid, which means four times a day) to get the individual dose:

Individual Dose

=

19.36

mL

4

=

4.84

mL

Individual Dose=

4

19.36 mL

=4.84 mL

5. Therefore, the number of milliliters given for each individual dose, given qid for a child who weighs 30 lb 4 oz, would be approximately 4.84 mL.
