An infant is delivered precipitously form a mother with no prenatal care. After resuscitation, the neonate does well for 2-3 hours, but then develops rapid breathing with grunting expirations, bluish appearance around the lips, and is rapid and labored with grunting.

|
|
A term 2-day-old infant stops breats-feeding after good intake. Respiratory distress develops with increased breathing and grunting expirations. The temperature is slightly low (36.5 C), but the physical examination and general activity seem normal. A chest x-ray shows normal lung fields with air throughout the GI tract. What is the most likely clinical diagnosis?
|
