ATI Nsg 234 Pediatrics Exam Questions
Extract:
A nurse is caring for an infant who has inadequate motility of a portion of the intestine, resulting in a mechanical obstruction.
Question 1 of 5
The nurse should identify this finding as a manifestation of which of the following disorders?
Correct Answer: B
Rationale: The correct answer is B: Hirschsprung's disease. This disorder is characterized by the absence of ganglion cells in the distal colon, leading to functional obstruction. The finding mentioned in the question is likely chronic constipation, a common symptom in Hirschsprung's disease due to the lack of peristalsis in the affected segment. Pyloric stenosis (
A) presents with projectile vomiting, not chronic constipation. Enterocolitis (
C) is associated with diarrhea and abdominal pain. Intussusception (
D) typically presents with colicky abdominal pain and a sausage-shaped mass on palpation.
Therefore, Hirschsprung's disease is the most likely diagnosis based on the manifestation described.
