EXAMPLE #1: The manufacturer's recommendation for pediatric Tylenol is
10 mg/kg/dose. How many mg are recommended for each
dose for a 20 kg child?
Calculate the dosage (mg) of Tylenol the child is to receive,
10 mg = X mg
1 X = 200 mg/dose for 20 kg child
The recommendation for Garamycin is 2 mg/kg/dose. The child
weighs 15 kg. The Garamycin is supplied 10 mg/ml. How many
mg are recommended for each dose for a 15 kg child? How
many ml are required for a single dose?
a. Calculate the dosage (mg) of Garamycin to be given to the
15kg child for one dose.
2 mg = X mg
1 X = 30 mg for the 15 kg child.
b. Calculate the amount (ml) of Garamycin to be given for one
= 30 mg
10 X = 30
X = 3 ml
Therefore, 3 ml will provide the recommended dose for a
15 kg child.
: A patient
who weighs 154 pounds
is to receive
that has a recommended one time dosage of 3 mg/kg. The
medication is stocked in a vial labeled 50 mg/ml. Calculate
the volume of the medication to be administered.
Convert the patient's body weight to kilograms.
2.2 X = 154
1 kg = X kg
X = 70 kg
