Correct answer: A. To identify possible drug interactions
- A. To identify possible drug interactions
- B. To ensure every drug has the same action

Explanation
Medication review helps identify interactions that may increase toxicity, reduce effectiveness or change drug levels. It cannot prevent every side effect, and medicines do not all have the same action.
