Rationale: A. Cyanotic skin indicates hypoxia and is a medical emergency requiring immediate intervention. B. Nasal flaring is a sign of increased respiratory effort and distress in infants. C. Productive cough is uncommon in young infants and less likely to be observed due to their limited ability to expectorate secretions. D. Crying during feeding may indicate difficulty breathing while feeding, a sign of respiratory compromise. E. Intercostal retractions reflect increased work of breathing and respiratory distress. F. Head bobbing is a late sign of respiratory distress in infants and suggests fatigue and possible impending respiratory failure.
