Stage 1 features of bronchopulmonary dysplasia occur how soon after birth?

Explanation:
Stage 1 of bronchopulmonary dysplasia reflects an acute lung injury that appears in the first days of life in preterm infants exposed to oxygen and ventilation. The hallmark findings are hyaline membranes lining the alveoli and areas of atelectasis, typically emerging about 2 to 4 days after birth. This early pattern represents the initial injury from surfactant deficiency and oxygen exposure before longer-term remodeling occurs. The other options don’t fit because immediate birth changes with alveolar hyperplasia aren’t the typical early stage, recovery by six weeks isn’t how BPD progresses, and the condition is not limited to full-term infants.
