There are a few different things that adcoms are looking for. Sometimes you can kill two birds with one stone but sometimes it is going to take a number of different activities to get all the experiences you'll want to have.
Do you know what a doctor does including: the length of the work day, the proportion of time spent in various tasks including direct patient contact, documentation and reimbursement tasks, seeking and providing consultation with colleagues and staff, continuing education, contact with patient's families in the absence of the patient, the various work environments/locations for that physician? Have you seen a variety of physicians enough to be able to compare and contrast among them?
Have you spent time with sick or injured people who are not your loved ones? (Being with loved ones can be an inspiration but will you really care about people you don't know and will never see again?) Given your experiences can you say that you are comfortable interacting with people who are in pain or distress, or bleeding profusely or deformed?
Have you had experiences that required you to interact with people you did not know well and to help them develop a sense of trust in you? Have you had experience dealing with people who are angry, frustrated, depressed, anxious, frightened, uncooperative, distraught? Given your past experience, do you feel comfortable handling people who are exhibiting those emotions?
Have you had experience that put you in a position of giving your time and talent to those who could not pay you for your services? Was that a one-time (temporary) thing or something that is a regular part of your life and something that you consider an obligation that you have to serve others (noblesse oblige, if you will) ?
So, how will you acquire these various experiences? There are plenty of different combinations of experiences that fit the bill and not all need to be clinical/medical settings.
