An infant's tongue, as well as a hyperflexed or hyperextended head, can easily obstruct the airway.

• A. Sometimes
• B. Not at all
• C. True
• D. False

Answer: (C)

Infants are especially prone to airway obstruction because the tongue is relatively large for the oral cavity and can fall back, narrowing or blocking the airway. The head position also has a big impact: hyperflexion (chin to chest) can push tissues toward the airway, while hyperextension (tilting the head back) can misalign the airway and crowd soft tissues. Because of these factors, keeping the infant’s head in a neutral, properly aligned position helps maintain an open airway. So, this statement is true.
