Which physical finding suggests increased work of breathing in a neonate?

• A. Nasal flaring
• B. Crackles
• C. Normal rate
• D. No retractions

Answer: (A)

In neonates, increased work of breathing is shown by signs of respiratory effort beyond normal calm breathing. Nasal flaring occurs because newborns are small and rely heavily on nasal airways; when they struggle to inhale, they widen the nostrils to reduce airway resistance and pull in more air. This visible effort is a direct cue that the baby is working harder to breathe, which is why nasal flaring is the best indicator among the options. Crackles are sounds from airway or lung pathology and don’t measure how hard the baby is working to breathe; a normal rate suggests breathing isn’t elevated, and no retractions indicate less chest-wall effort.
