The clinic nurse reviews the record of an infant and notes that the primary healthcare provider has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek healthcare for the infant?

Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is a congenital anomaly characterized by an absence of ganglion cells in the rectum and other areas of the affected intestine. A key clinical manifestation of Hirschsprung's disease is chronic constipation that starts in the first month of life, leading to pellet-like or ribbon-like stools that have a foul smell. Another sign is the delayed passage or absence of meconium stool in the neonatal period. In addition to foul-smelling, ribbon-like stools, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive are also common clinical manifestations of this disorder. Options A, B, and C are not typically associated with Hirschsprung's disease, making them incorrect choices in this scenario.
