Why do infants and young children develop respiratory distress more quickly in acute and chronic alterations of the respiratory system?
a. They have a widened, shorter airway.
b. There is a defect in their sucking ability.
c. The gag reflex increases mucus production.
d. Mucus and edema obstruct small airways.
D
The airway in infants and young children is narrower, not wider; respiratory distress can occur quickly because mucus and edema can cause obstruction to their small airways. Sucking is not necessarily related to problems with the airway. The gag reflex is necessary to prevent aspiration. It does not produce mucus.
