A nurse is caring for a 3-year-old child. 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.

• Irritability: The child is restless and agitated, which is common in both upper and lower respiratory infections. Irritability reflects systemic response to infection, fever, and airway discomfort. It is an important indicator for monitoring respiratory status and overall well-being. • Stridor: Inspiratory stridor is a hallmark of croup (acute laryngotracheobronchitis) due to airway inflammation and narrowing in the larynx and trachea. Stridor is typically absent in pneumonia, which primarily affects the lower airways. • Temperature: The child has a low-grade fever (38.1–38.2° C), which is common in both croup and pneumonia. Fever indicates an inflammatory response to infection, and monitoring trends is important for evaluating disease progression or complications. • Cough findings at 0800: The barking, non-productive cough is characteristic of croup, caused by inflammation of the upper airway. Pneumonia usually produces a productive cough with sputum and may involve lower respiratory symptoms like wheezing, crackles, or decreased breath sounds.
