The President questions are part of a mini mental status exam. Some mental health/medical profssional give them routinely. It is to make sure you are cognitively in the here and now. In school they seemed so bizarre, I thought you would just know if someone was out of it. And then I was with my MIL when she took hers. (she has mild dementia) She remembered Obama was the Pres, but thought Clinton was the president before.
