A nurse is assessing a 2-month-old infant who has an acute respiratory tract infection. Which of the following findings should the nurse identify as requiring intervention? (Select All that Apply.)

A. Cyanosis, particularly central cyanosis (bluish discoloration of the lips, tongue, or trunk), indicates inadequate oxygenation of the blood. In a 2-month-old infant, this is a critical emergency because infants have limited oxygen reserves and can deteriorate rapidly. Immediate interventions may include supplemental oxygen, airway assessment, and escalation to higher-level care. B. Nasal flaring is an early sign of increased respiratory effort in infants. It occurs as the infant tries to decrease airway resistance and increase airflow during inspiration. This finding indicates moderate respiratory distress and should prompt close monitoring and intervention to prevent progression to respiratory failure. C. While a cough is a common symptom of respiratory infections, a productive cough alone is not an urgent finding in infants. It may indicate the body’s normal mechanism to clear secretions. However, if accompanied by difficulty breathing, cyanosis, or poor feeding, it would require intervention. D. Crying during feeding is often related to discomfort, congestion, or mild illness. Although it can increase oxygen demand, it is not a primary indicator of respiratory distress and does not alone require urgent intervention. E. Retractions occur when the chest wall is pulled inward during inspiration, indicating that the infant is using accessory muscles to breathe. Intercostal retractions are a moderate to severe sign of respiratory distress and require intervention, such as oxygen therapy or respiratory support, to prevent fatigue and respiratory failure. F. Head bobbing is a late and severe sign of respiratory distress in infants, resulting from the use of sternocleidomastoid and accessory neck muscles to assist breathing. This indicates that the infant is near respiratory exhaustion and requires immediate intervention to maintain airway patency and oxygenation.
