Which pediatric airway feature increases the risk of airway obstruction in children compared with adults?

• A. The tongue is relatively larger in children, the airway is smaller and more prone to obstruction, and the epiglottis is more floppy
• B. The tongue is smaller in children
• C. The airway is longer
• D. The epiglottis is stiffer

Answer: (A)

In pediatric airways, obstruction risk rises because anatomy shifts the balance toward easier blockage. The tongue is relatively larger in children, the airway itself is smaller in diameter, and the epiglottis tends to be more floppy. A relatively large tongue can slide back and partially occlude the airway, especially when a child is supine or not yet fully awake. A smaller airway means any tissue or swelling reduces airflow more dramatically, since resistance increases steeply as the radius shrinks. A floppy epiglottis can more readily bend into the airway during movement or ventilation efforts, further increasing obstruction risk. The combination of these features is what makes pediatric airways more prone to obstruction than adults. If the tongue were smaller, the airway lengthened, or the epiglottis were stiffer, obstruction would be less likely, so those options don’t fit the scenario.
