From GT:
"A 52-hour-old neonate has developed abdominal distension and bilious vomiting. She has also failed to pass meconium per rectum. She is diagnosed with meconium ileus. Where is the obstruction most likely to be found?
A. Distal jejunum
B. Mid-ileum
C. Ascending colon
D. Sigmoid colon
E. Proximal duodenum
Answer Explanation
The correct answer is B.
Meconium ileus usually is the result of inspissated meconium plugs in the mid-ileum. The three cardinal signs of intestinal obstruction are abdominal distention, bilious vomiting, and failure to pass meconium within 48 hours."

When I read this question, I initially thought CF or Hirschsprung's, but then decided Hirschsprung's based on the bilious vomiting and abdominal distension. I would have assumed that the obstruction would be as distal as possible. Notice that the explanation doesn't give a diagnosis.
Could someone please share thoughts here?
Cheers,
