Ellen James, age 18, comes to the rural health clinic for a checkup

required for college admission. During the health interview, she tells the nurse that she is sexually active. When the nurse questions her about safe sex practices, Ellen replies, "What do you mean by that? My boyfriends aren't sick, and besides, young people don't get AIDS."
