Which condition commonly affects children aged 6 months to 4 years and presents with a seal bark cough?

• A. Croup
• B. Epiglottitis
• C. Bronchiolitis
• D. Pneumonia

Answer: (A)

This item tests recognizing croup by its hallmark barking cough in young children. In kids about 6 months to 4 years, inflammation and swelling in the larynx and subglottic space narrow the upper airway, producing a distinctive seal-like or barking cough, often with hoarseness and sometimes inspiratory stridor, especially at night. That pattern fits typical viral laryngotracheitis seen in this age group, making it the best match.

Epiglottitis, by contrast, usually shows abrupt onset high fever, drooling, and a toxic appearance with the child leaning forward, not a barking cough. Bronchiolitis generally presents with wheezing, tachypnea, and crackles in younger infants rather than a barky cough. Pneumonia tends to come with fever and a productive or localized chest exam rather than the classic upper airway noise described here.
