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.
