Croup typically presents with which symptom?

• A. Runny nose
• B. Barking cough
• C. Fever over 38.5 C
• D. Wheezing on expiration

Answer: (B)

Croup is an upper airway inflammatory process that narrows the larynx and trachea, producing a distinctive barking cough. That cough is the hallmark feature because it reflects the subglottic swelling and irritation in the vocal tract, giving a harsh, seal-like sound, often with hoarseness and sometimes inspiratory stridor. Other symptoms like a runny nose or higher fever can occur with many viral infections and aren’t specific to croup, while wheezing on expiration is more typical of lower airway diseases such as bronchiolitis or asthma. So the barking cough best identifies croup.
