A 18-month-old patient is admitted to the hospital with acute laryngotracheobronchitis. The patient is placed in a mist tent with compressed air. Which of these symptoms would be an early sign of hypoxia?


•Laryngotracheobronchitis, or Croup, is the inflammation of the larynx, trachea, and major bronchi.

•A child with laryngotracheobronchitis is placed in a mist tent primarily to increase oxygen and carbon dioxide exchange.

•Early signs of hypoxia include restlessness, headache, fatigue, shortness of breath, and cyanosis.

•Incorrect: Flushing of the face and mouth breathing are not signs of hypoxia.

•Incorrect: Croup is associated with a barking cough, but this is a symptom, not a sign of hypoxia.
