An infant who has aganglionic megacolon causing decreased motility of part of the intestine
Question 1 of 5
A nurse is caring for an infant who has aganglionic megacolon causing decreased motility of part of the intestine. The nurse should identify this finding of mechanical obstruction as a manifestation of which of the following disorders?
Correct Answer: C
Rationale: The correct answer is C, Hirschsprung's disease. This condition is characterized by the absence of ganglion cells in the distal colon, leading to decreased motility and mechanical obstruction. Pyloric stenosis (
A) involves narrowing of the opening between the stomach and small intestine, not the colon. Encopresis (
B) is fecal incontinence unrelated to mechanical obstruction. Enterocolitis (
D) is inflammation of the intestines, not a structural issue like Hirschsprung's disease.
