A call comes into the station at 0400 hours. The dispatcher sends your engine crew to a shelter for homeless people for an "ill person". When you enter the shelter, an attendant says, "Hank just came in last night. He lost his job and then his room. He tells us that he can't shake this cough, that it's been troubling him for some time. He's awfully thin, which is to be expected from living on the streets. I found him in the bathroom, on the floor, coughing up blood. I got him back to bed, but I'm worried about him. He's only 21. Could you take a look at him?"
