A) Infant's age in months/150 months times the average adult dose

C) Weight of child in pounds/150 pounds times the average adult dose

C
Feedback:
Clark's rule uses the child's weight to calculate the dose and assumes the adult dose is based on a 150-pound person. Fried's rule applies to a child younger than 1 year of age and assumes that an adult dose would be appropriate for a child who is 12.5 years (150 months) old. Young's rule applies to children 1 to 12 years of age. Surface area calculation of a child's dose is determined with the use of a nomogram including the child's height and weight.
