The formula [Age/(Age + 12)] x Adult Dose is used to calculate which of the following?

The formula [Age/(Age + 12)] x Adult Dose is specifically designed for calculating a pediatric dose based on the age of the child in relation to an adult dose. This method is commonly referred to as Young's formula for pediatric dosing. The formula helps to adjust medication doses for children, taking into account their age and metabolic differences compared to adults.

Young's formula is particularly useful because it provides a straightforward way to estimate pediatric doses that maintains a proportional relationship to the adult dosage. By adding 12 to the age, the formula accounts for the fact that a child's body is still developing, so it alters the dose to better suit their physiological state while still referencing a standard adult dose.

In contrast, other methods such as Clark's formula and Webster's formula utilize different parameters for their calculations, often based on weight or different age relationships. The standard pediatric dose methods typically refer to predetermined dosages rather than using a formulaic approach like Young's. Thus, recognizing this formula as Young's formula confirms its specific application in adjusting dosages for pediatric patients based on their age compared to adult standard doses.
