Abstract
Returning to the office after a long work day, Kristin, a hospice nurse, learns that the nighttime on-call nurse is ill. Kristin agrees to take call and hopes it will be a slow night. Now it is 2 am and Kristin has to travel to a client's home. Yawning repeatedly and driving over the rumble strip on the highway, she turns on the radio and opens the car window to the chill air, trying to shock herself into alertness.
