A child with laryngotracheobronchitis (croup) is placed in a cool mist tent. The mother becomes concerned because the child is frightened, consistently crying and trying to climb out of the tent. Which is the most appropriate nursing action?

1. Tell the mother that the child must stay in the tent. 2. Place a toy in the tent to make the child feel more comfortable. 3. Call the health care provider and obtain a prescription for a mild sedative. 4. Let the mother hold the child and direct the cool mist over the child's face.
