Which statement describes the clinical presentation of IRDS after birth?

• A. A few hours after birth the infant has nasal flaring, retractions, tachypnea, cyanosis, refractory hypoxemia
• B. Immediate Improvement And Stable Oxygenation
• C. No Respiratory Distress
• D. Hypervolemia With Edema

Answer: (A)

IRDS presents with rapid onset respiratory distress after birth due to insufficient surfactant, which causes the lungs to collapse and become stiff, leading to poor oxygen exchange. A few hours after birth, the infant typically shows increased work of breathing—nasal flaring and chest retractions—along with rapid breathing (tachypnea) and cyanosis. The oxygen level remains low despite supplemental oxygen, known as refractory hypoxemia, because the alveoli are widely collapsed and ventilation–perfusion matching is severely disrupted. This pattern matches the described scenario, making it the best description of IRDS presentation. The other options describe no distress, immediate improvement, or fluid overload, which do not align with the characteristic early respiratory failure seen with surfactant deficiency.
