Which finding is NOT consistent with bronchopulmonary dysplasia?

• A. Thermal instability
• B. Tachypnea
• C. Persistent cyanosis
• D. Retractions

Answer: (A)

Bronchopulmonary dysplasia presents as a chronic lung injury in preterm infants, with ongoing respiratory distress and impaired gas exchange. The features you’d expect reflect this increased work of breathing and oxygen need: tachypnea from the effort to ventilate stiff or damaged lungs, persistent cyanosis due to limited oxygenation, and retractions from airway resistance and chest wall effort. Thermal instability, on the other hand, isn’t a characteristic finding of BPD. It more often points to systemic issues like infection or metabolic problems and would lead you to look for sepsis or other causes of temperature instability. So, while the respiratory signs fit BPD, thermal instability does not.
