In the emergency department, which finding requires immediate intervention?

• A. Thick yellow rhinorrhea
• B. Frequent nonproductive cough
• C. Oxygen saturation is 95% by pulse oximeter
• D. Prolonged exhalations

Answer: (D)

The key idea is recognizing signs of acute airway obstruction in a child that call for immediate action in the emergency setting. Prolonged exhalations indicate increased airway resistance and obstructive airway disease, such as an asthma attack, where the child is working hard to exhale and is at risk of rapid deterioration. This pattern signals that the patient needs prompt intervention to relieve the obstruction and stabilize breathing.

In contrast, thick yellow rhinorrhea points to an infection but isn’t an urgent red flag by itself; a frequent nonproductive cough can be from a viral process or a mild airway irritation and isn’t inherently emergent; an oxygen saturation of 95% is within normal limits and does not by itself require urgent intervention. Thus, the finding of prolonged exhalations is the one that most strongly indicates the need for immediate management.
