The formula (weight/150 lb.) x Adult Dose corresponds to which dosing method?

The formula (weight/150 lb.) x Adult Dose is representative of Clark's PED Dose. This method is specifically designed to calculate pediatric drug dosages based on the weight of an individual child compared to a standard adult weight of 150 pounds. Clark's formula provides a way to ensure that dosages are adjusted appropriately for the size of the patient, reflecting the principle that smaller individuals require smaller doses of medication.

Clark's formula uses the weight of the child in relation to 150 pounds because it considers this weight as a standard for adult dosage. This helps to prevent underdosing or overdosing in pediatric patients, which can be critical in clinical settings such as radiology where precise dosing is essential for safety and efficacy.

The other options, while also related to pediatric dosing, use different methodologies or standards for calculations. For instance, Webster’s formula typically involves age and weight, Young’s formula is based on age, and Miller’s formula has its unique parameters for dosing. Clark's formula remains one of the more straightforward and widely used methods to adjust adult dosages for children based on their weight relative to a typical adult.
