They ask so many questions to keep you safe and to make the anesthesia and surgery plan fit you. Your anesthesiologist and surgical team use your answers to learn about your health, medicines, allergies, past reactions to anesthesia, and any family history of problems with surgery or anesthesia. They also ask about alcohol or recreational drug use, because these can change how you react to anesthesia and pain control.

The questions also help the team check that the right surgery is being done on the right person and the right body part. They may confirm your name, the surgical site, your consent form, and your allergies more than once on purpose. This repetition is part of the safety checks.

They also use your answers to decide what tests you may need, what medicines to continue or stop, when to stop eating and drinking, and how to plan your recovery and pain control.
