to know how many people take medicines to keep track of all of the people who are sick to keep track of the next scheduled appointments to know if there is a risk for harmful side effects
I gave my students this multiple choice question: Which best explains why it is important for a doctor's office to keep accurate records of the medicines prescribed for their patients?

Only one answer is correct among these 4 choices:
- to know how many people take medicines
- to keep track of all of the people who are sick
- to keep track of the next scheduled appointments
- to know if there is a risk for harmful side effects

Could you tell me which one is correct?

to know if there is a risk for harmful side effects
