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

A. Tell the parent that the child must stay in the tent. This lacks empathy and may increase the child’s anxiety. Forcing a frightened child to stay in the tent may worsen distress and respiratory symptoms. B. Call the pediatrician and obtain a prescription for a mild sedative. Sedation is not a first-line intervention in a child with croup and can depress respiratory effort-potentially dangerous. C. Let the parent hold the child and direct the cool mist over the child's face. This maintains the therapeutic effect of the mist while providing comfort and reducing distress, which helps prevent worsening of symptoms like stridor. D. Place a toy in the tent to make the child feel more comfortable. While toys can distract, this does not address the child’s distress and desire to be held. It’s not an effective or immediate solution.
