A nurse is caring for a 3-year-old child client in the emergency department. For each of the following findings, click to specify if the finding is consistent with acute laryngotracheobronchitis or pneumonia. Each finding may support more than one disease process.

Cough findings at 0800: The "barking," non-productive cough is the hallmark sign of acute laryngotracheobronchitis (croup), caused by inflammation of the larynx and trachea. Pneumonia typically presents with a productive or "wet" cough. Temperature: A low-grade fever (38.1°–38.2° C) is consistent with both conditions, as both are inflammatory/infectious processes. Irritability: Restlessness and agitation are common in both; in croup, it often stems from respiratory distress and the frightening nature of the cough/stridor, while in pneumonia, it may be due to hypoxia or general malaise. Stridor: This high-pitched, inspiratory sound is specific to croup (upper airway obstruction). Pneumonia is a lower respiratory tract infection and is more likely to produce crackles or wheezing rather than stridor.
