My answer: Well if it happens that I end up not knowing something about medicine (as will most likely happen), it may result in hurting a patient or putting a patient in danger. There's no way one can predict every outcome in a doctor-patient scenario, and so I also agree that not everything can be learned in medicine. However, I would do my best at learning from the mistakes made, and keep an open mind at all times towards learning and criticism. Getting the knowledge is one thing, but each new encounter with a patient is a new and unpredictable one.
Did I do okay? 🙂
