Infant with inadequate motility of part of the intestine
Question 1 of 5
A nurse is caring for an infant who has inadequate motility of part of the intestine resulting in a mechanical obstruction. The nurse should identify this finding as a manifestation of which of the following disorders?
Correct Answer: D
Rationale: The correct answer is D: Hirschsprung's disease. This disorder is characterized by inadequate motility in part of the intestine due to the absence of ganglion cells in the affected segment. This absence leads to mechanical obstruction, resulting in symptoms such as constipation, abdominal distention, and failure to pass meconium. Pyloric stenosis (choice
A) is a narrowing of the opening between the stomach and the small intestine, causing projectile vomiting. Enterocolitis (choice
B) is inflammation of the colon and small intestine, leading to diarrhea and abdominal pain. Encopresis (choice
C) is the involuntary passage of stool in inappropriate places, often due to constipation.
Therefore, Hirschsprung's disease is the correct choice based on the manifestation of inadequate motility and mechanical obstruction in the intestine.
