Question

Which of the following factors determine dosage calculations? Choose all that apply.

patient’s age

condition being treated

patient’s weight

patient’s height

Answer 1

All of them.

- Patient’s age — affects metabolism, organ function and age-specific dosing (especially neonates/children/elderly).
- Condition being treated — determines the appropriate drug and therapeutic dosing range.
- Patient’s weight — commonly used for mg/kg dosing and affects distribution and clearance.
- Patient’s height — used with weight to calculate body surface area (BSA), which guides dosing for some drugs (e.g., chemotherapy).
