For additional MMI Interview Scenarios and model answers, review our Medical School Interviewer Approved MMI Question Bank.

Birth Control
A 14-year-old patient requests birth control pills from you and asks that you not tell her parents. What would you do?

Alternative Medicine

A member of your family decides to depend solely on alternative medicine for the treatment of his or her significant illness. What action would you take, if any?

You are a general practitioner and a mother comes into your office with her child who is complaining of flu-like symptoms. Upon entering the room, you ask the boy to remove his shirt and you notice a pattern of bruises on the boy’s torso. You ask the mother where the bruises came from, and she tells you that they are from a procedure she performed on him known as “Cao Gio,” which is also known as “coining.” The procedure involves rubbing warm oils or gels on a person’s skin with a coin or other flat metal object. The mother explains that Cao Gio is used to raise out bad blood, and improve circulation and healing. When you touch the boy’s back with your stethoscope, he winces in pain from the bruises. You debate whether or not you should call Child Protective Services and report the mother. When should a physician step in to stop a cultural practice? Should the physician be concerned about alienating the mother and other people of her ethnicity from modern medicine?

Dr Blair recommends homeopathic medicines to his patients. There is no scientific evidence or widely accepted theory to suggest that homeopathic medicines work, and Dr Blair doesn’t believe them to. He recommends homeopathic medicine to people with mild and non-specific symptoms such as fatigue, headaches, and muscle aches because he believes that it will do no harm, but will give them reassurance. Consider the ethical problems that Dr Blair’s behaviour might pose.

Justice & Public Health

 A Vancouver biotech company was hired by the US Military to develop a cure for Ebola. They successfully developed a vaccine to treat the symptoms of the virus and lowered the mortality rate for infected patients. Discuss the implications of this on a global scale.

Discuss the ethics of treatment resources being used on patients who knowingly ignore public health advice on smoking and exercise.

Genetic Counselling

You are a genetic counsellor. One of your clients, Linda, had a boy with a genetic defect that may have a high recurrence risk, meaning her subsequent pregnancies has a high chance of being affected by the same defect. You offered genetic testing of Linda, her husband, and their son to find out more about their disease, to which everyone agreed. The result showed that neither Linda nor her husband carries the mutation, while the boy inherited the mutation on a paternal chromosome that did not come from Linda’s husband. In other words, the boy’s biological father is someone else, who is unaware that he carries the mutation. You suspect that neither Linda nor her husband is aware of this non-paternity. How would you disclose the results of this genetic analysis to Linda and her family? What principles and who do you have to take into consideration in this case?


If you have the choice of giving a liver transplant to a successful elderly member of the community and a 20-year-old drug addict, who would you allocate the organ to? And what factors would influence your decision?

You have a patient who was a chronic alcoholic and wants a liver transplant. Would you add this patient to the transplant waiting list?

Would you give a liver transplant to an alcoholic?

Autonomy & Consent

An eighteen-year-old female arrives in the emergency room with a profound nosebleed. You are the physician, and you have stopped the bleeding. She is now in a coma from blood loss and will die without a transfusion. A nurse finds a recently signed card from Jehovah’s Witnesses Church in the patient’s purse refusing blood transfusions under any circumstance. What would you do?

Is it ever okay to lie to a patient?

Your mother calls you and asks you to help with a major family decision. Your maternal grandfather is 70 years old and has been diagnosed with a condition that will kill him sometime in the next five years. He can have a procedure that will correct the disease and not leave him with any long-term problems, but the procedure has a 10% mortality rate. He wants to have the procedure, but your mother does not want him to. How would you help mediate this issue?

How would you handle a situation as a medical student if an attending physician demanded (at the risk of you not getting your first choice residency program) that you take pictures of a patient for a research paper without getting approval from the patient?

 The Canadian Paediatric Association has recommended that circumcisions ‘not be routinely performed’.  They base this recommendation on their determination that ‘the benefits have not been shown to clearly outweigh the risks and costs’. Doctors have no obligation to refer for, or provide, a circumcision, but many do, even when they are clearly not medically necessary. BC Medicare no longer pays for unnecessary circumcisions. Consider the ethical problems that exist in this case. Discuss these issues with the interviewer.

A woman enters the emergency room with stomach pain. She undergoes a CT scan and is diagnosed with an abdominal aortic aneurysm. The physicians inform her that the only way to fix the problem is surgically and that the chances of survival are about 50/50. They also inform her that time is of the essence, and that should the aneurysm burst, she would be dead in a few short minutes. The woman is an exotic dancer; she worries that the surgery will leave a scar that will negatively affect her work; therefore, she refuses any surgical treatment. Even after much pressuring from the physicians, she adamantly refuses surgery. Feeling that the woman is not in her correct state of mind and knowing that time is of the essence; the surgeons decide to perform the procedure without consent. They anaesthetize her and surgically repair the aneurysm. She survives and sues the hospital for millions of dollars. Do you believe that the physician’s actions can be justified in any way? Is it ever right to take away someone’s autonomy?

You have a patient who just lost his wife and found that he has prostate cancer but refuses treatment. His family is begging you to force him to have the treatment done. What are the main ethical issues in this scenario?

Would you tell someone they have a debilitating disease (e.g. cancer) even if their spouse begs you not to because it would crush them because a relative died of the same disease previously?

You recommend chemotherapy for your teenage cancer patient, but his mother refuses treatment because she’s afraid chemotherapy will make him sick. What action would you take, if any?

In 2007, The American Family Physician Journal published an article exploring the issue of physicians as role models, using a scenario in which an obese physician is offering nutrition and exercise counselling to his obese patients. According to the authors’ research, patients have more confidence in the health-counselling advice of non-obese versus obese physicians, and physicians with poor personal lifestyle habits are less likely to counsel patients about a healthy lifestyle.
