These are some questions that I asked while I shadowed. The information you gather from these Q's will help you understand the medical field and even strongly answer some questions on secondary applications and during interviews: How do you feel the affordable care act will change the way you practice? How important is teamwork in your line of work? How do you deliver bad news to a patient? Have you ever dealt with a patient who was rude or aggressive towards you, and how do you handle that? What was the hardest part about medical school? Has a patient's religious or spiritual views ever impacted the way you approach treatment, and if so how?
Obviously, these are Q's that you don't ask all at once, but I think it's in your best interest to ask these Q's along the way so that you understand the field a little better and know how you could approach difficult situations as a future physician. This will help you immensely during interviews and when you write your essays.
