What is a common sign of an upper airway obstruction in a child?

• A. Wheezing
• B. Grunting
• C. Stridor
• D. Rales

Answer: (C)

Stridor is a high-pitched, wheezing sound typically heard during inhalation and is a common indicator of upper airway obstruction in children. It occurs due to turbulent airflow passing through a narrowed or obstructed airway. In pediatric patients, this can be caused by several factors, including croup, foreign body aspiration, or anaphylaxis. When the airway is compromised at the level of the larynx or trachea, the characteristic sound of stridor emerges, alerting caregivers to the seriousness of the situation. This sign is particularly critical to note given that it requires immediate assessment and potentially urgent intervention, as it can indicate a significant risk of respiratory distress or failure. The other options, like wheezing, primarily suggest lower airway issues such as asthma or bronchiolitis, while grunting indicates respiratory distress related to poor oxygenation rather than an obstruction. Rales, or crackles, are associated with fluid in the lungs and are not indicative of upper airway obstruction. Therefore, identifying stridor is essential for recognizing and addressing potential life-threatening conditions in pediatric patients.
