Your unit responds to a child who fell down the stairs. On arrival you are met by an anxious mother who states that her 5-year-old son left the basement door open and her 8-month-old son went through the open door in his walker and fell down the flight of stairs. Your initial assessment finds a conscious 8-month-old child in his mother's arms, he is not crying and does not respond to your presence or his mother's voice.
