Question

Quizplus · Accepted Answer

Respiratory distress and hypoxemia in laryngotracheobronchitis are caused by mucosal edema and laryngeal secretions, which can obstruct the airway and impair gas exchange. Infectious pulmonary edema and decreased surfactant are not typical causes of this condition. While nasopharyngeal obstruction can contribute to the development of laryngotracheobronchitis, it is not the primary cause of respiratory distress and hypoxemia.
