Bronchopulmonary dysplasia typically develops after treatment for which initial lung condition?

• A. TTN
• B. RDS
• C. Meconium aspiration
• D. CDH

Answer: (B)

Bronchopulmonary dysplasia is a chronic lung injury that most commonly follows prolonged respiratory support for an immature lung. In preterm infants with surfactant deficiency, respiratory distress syndrome often requires mechanical ventilation and high oxygen. The combination of immature alveolar development, inflammation, oxygen toxicity, and ventilator-related injury disrupts normal lung growth and leads to fibrotic changes characteristic of BPD. While other newborn lung issues can cause acute problems, BPD most classically develops after treatment for respiratory distress syndrome, making that initial condition the best fit.
