Match each neonatal clinical presentation with its most likely underlying diagnosis.
- A 35-week gestation neonate delivered via precipitous vaginal delivery develops tachypnea and grunting at 1 hour of life. Chest radiograph reveals hyperinflation, fluid in the interlobar fissures, and prominent perihilar streaking.Transient tachypnea of the newborn
- A 29-week gestation neonate develops severe respiratory distress immediately after birth. Chest radiograph demonstrates a diffuse ground-glass appearance, low lung volumes, and prominent air bronchograms.Respiratory distress syndrome
- A 41-week gestation neonate born through thick, greenish fluid develops respiratory failure shortly after birth. Chest radiograph shows coarse, irregular opacities, areas of hyperinflation, and flattening of the diaphragm.Meconium aspiration syndrome
- A 39-week gestation neonate presents with severe cyanosis and respiratory distress immediately after birth. Physical examination reveals a barrel-shaped chest, a scaphoid abdomen, and absent breath sounds on the left side.Congenital diaphragmatic hernia
Answer
The presentations match as follows: The near-term neonate with fluid in the fissures has Transient tachypnea of the newborn. The premature neonate with a ground-glass appearance has Respiratory distress syndrome. The post-term neonate with coarse opacities has Meconium aspiration syndrome. The neonate with a scaphoid abdomen has a Congenital diaphragmatic hernia.
Each clinical scenario provides a pathognomonic triad of gestational age, physical examination findings, and radiographic evidence that exclusively points to one underlying etiology for respiratory distress.
Step-by-Step Solution
Key Concept
Differentiating causes of neonatal respiratory distress requires integrating gestational age, delivery history, physical examination, and characteristic radiographic findings.
