The method used to calculate a child's dose based on age and weight can indeed include all of the mentioned rules: Clark's Rule, Fried's Rule, and Young's Rule. Each of these formulas offers a different approach to adjusting medication dosages for pediatric patients, which is crucial for ensuring safety and efficacy in drug administration.

Clark's Rule calculates the appropriate dosage based on the child's weight, typically in kilograms. By using this formula, healthcare providers can tailor the medication amount specifically to the child's size, which is often more reflective of how their body will respond compared to standard adult dosages.

Fried's Rule, on the other hand, is based on the age of the child. It is typically used for infants and very young children, providing a straightforward way to estimate drug dosages according to their age in years. This is particularly helpful when weight data is unavailable or when calculating doses for younger patients.

Young's Rule also takes age into account but does so with a formula that allows for adjustments as the child grows older. It helps determine a more accurate measurement as children mature and gain weight, providing a bridge between age-based dosing and weight-based methods.

Since these three methods can all be utilized to calculate a child's medication dosage, acknowledging that all of them
