Write answer in between .Q:Thirty minutes after delivery, a 1780-g 3-lb 15-oz male newborn develops respiratory distress. He was born at 30 weeks gestation via vaginal delivery. His temperature is 36.8C 98.2F, pulse is 140min, respirations are 64min, and blood pressure is 6132 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 90. Examination shows pale extremities. Grunting and moderate subcostal retractions are present. Pulmonary examination shows decreased breath sounds bilaterally. Supplemental oxygen is administered. Ten minutes later, his pulse is 148min and respirations are 66min. Pulse oximetry on 60 oxygen shows an oxygen saturation of 90. Which of the following is the most likely diagnosis?? A: Respiratory distress syndrome, B: Meconium aspiration syndrome, C: Tracheomalacia, D: Neonatal pneumonia, E: Tracheoesophageal fistula,  <response>: This is a question about respiratory distress in a premature newborn. The key findings are:- 30 weeks gestation - Respiratory distress shortly after birth- Tachypnea, grunting, retractions - Decreased breath sounds- Low oxygen saturation not improving with supplemental oxygenThese findings are classic for respiratory distress syndrome RDS in a premature infant. RDS is caused by surfactant deficiency in the lungs. Meconium aspiration, tracheomalacia, pneumonia, and tracheoesophageal fistula would not present this way in a premature newborn.A: Respiratory distress syndrome
