A baby is born at 30 weeks of gestation by cesarian delivery Neonate develops tachypnea, flaring, subcostal and intercostal retractions immediately after birth. Chest radiography shows bilateral, diffuse, ground glass appearance and air – bronchogram sign present. Doctor started surfactant therapy within 1 hour of onset of respiratory distress. This is known as_____

**Core Concept**
Respiratory distress syndrome (RDS) is a condition characterized by difficulty breathing in premature infants due to a lack of surfactant production in the lungs, leading to alveolar collapse and impaired gas exchange.

**Why the Correct Answer is Right**
The described scenario is consistent with RDS in a premature infant. The baby's symptoms, such as tachypnea, flaring, subcostal and intercostal retractions, and the chest radiography findings, including a bilateral, diffuse, ground glass appearance and air-bronchogram sign, are characteristic of RDS. The administration of surfactant therapy within 1 hour of onset of respiratory distress is an evidence-based treatment for RDS, which helps to reduce alveolar surface tension and improve lung compliance.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not provided. Please provide the distractors for a complete explanation.
* **Option B:** While respiratory failure can be a component of RDS, this answer is too broad and does not specifically describe the condition as RDS.
* **Option C:** This option is not provided. Please provide the distractors for a complete explanation.
* **Option D:** This option is not provided. Please provide the distractors for a complete explanation.

**Clinical Pearl / High-Yield Fact**
Surfactant therapy is most effective when administered within the first hour of respiratory distress in premature infants, as this can significantly improve lung function and reduce the risk of respiratory failure.

**Correct Answer:** A. Respiratory Distress Syndrome

✓ Correct Answer: C. Early rescue therapy
