Final answer:
The four methods in calculating drug dosages for pediatric patients are Body Surface Area (BSA) Method, Body Weight Method, Age Method, and Clark's Rule.
Step-by-step explanation:
The four methods used in calculating drug dosages for pediatric patients are:
- Body Surface Area (BSA) Method: This method takes into account the child's weight and height to calculate the dosage. It is often used for chemotherapeutic drugs.
- Body Weight Method: This method calculates the dosage based on the child's weight. It is commonly used for antibiotics and analgesics.
- Age Method: This method assigns a specific dosage based on the child's age. It is frequently used for vaccines and certain medications.
- Clark's Rule: This method calculates the dosage based on the child's weight and a fraction of the adult dosage. It is commonly used for oral liquids and suspensions.
