Final answer:
Drug calculations for children consider age, weight, and height, with weight being the most significant factor for determining dosages appropriate for a child's body composition and developmental stage.
Step-by-step explanation:
Drug calculations for children are primarily based on factors such as age, weight, and height. These factors are vital as they influence the pharmacokinetics of drugs in the body, determining the correct and safe dosage for pediatric patients. Weight is often considered the most crucial parameter because it closely correlates with the body's capacity to absorb, distribute, metabolize, and excrete medications. Although sex may influence drug pharmacokinetics, it is not typically a primary consideration in pediatric dosing like it can be for adults. Instead, healthcare professionals use weight-based calculations and may adjust dosages based on specific growth charts and development stages, ensuring that the administered doses are appropriate for the child's physical maturity and body composition
