This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Pediatrics
A neonate passes black colored meconium after 12 hrs of bih. True statement is: 
Select and explain. 
A. Intestinal haemorrhage, B. Fibrocystic disease of pancreas, C. Normal findings, D. Hirschsprung's disease
C: Normal findings
Answer: C: Normal findings 
Explanation: Meconium stooling is seen in 90 percent of newborns within the first 24 hours, and most of the rest within 36 hours. The passage of meconium and urine indicates patency of the gastrointestinal and urinary tracts. Failure of the newborn to stool or urinate after these times suggests a congenital defect, such as imperforate anus or a urethral valve.
