Question

a pharmacy technician is preparing to fill a prescription for a toddler. which of the following is the weight - based formula the technician should use to determine the correct pediatric dose?
young’s rule
alligation method
clark’s rule
fried’s rule

Explanation:

To determine the correct pediatric dose for a toddler based on weight, we analyze each option:

• Young’s rule: Uses age (in years) to calculate pediatric doses, not weight.
• Alligation method: Used for mixing solutions of different strengths, not for weight - based pediatric dosing.
• Clark’s rule: Is a weight - based formula for calculating pediatric doses. It takes into account the child's weight (in pounds or kilograms) relative to an average adult weight to determine the appropriate dose.
• Fried’s rule: Uses the child's age in months for dose calculation, not weight.

Since the question asks for a weight - based formula for pediatric dosing, Clark’s rule is the correct choice.

Answer:

C. Clark’s rule
