Read the following hypothetical situation and answer the questions that follow:

An elderly gentleman presents himself to the emergency department of a small community hospital. The patient has contractures and paralysis of his left hand; he apparently has complete expressive and at least partial receptive aphasia. Upon questioning, the man takes off his right shoe and points to his right great toe and grimaces, apparently indicating a problem in that area. The nurse is unable to gather any further information from him because of his difficulty in communicating. In attempting to help him, she asks if he has a neighbor or friend accompanying him. He shakes his head, indicating that he is alone. Curious, the nurse asks him how he came to the hospital. The patient smiles and proudly produces a driver’s license from his shirt pocket. Subsequently, the nurse leaves the room and returns a few minutes later to find that the patient left the hospital, having received no care. The nurse suspects that because of his current physical condition the man is unsafe to drive a motor vehicle.
