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?
Hirschsprung’s disease.
Encopresis.
Pyloric stenosis.
Enterocolitis.
The Correct Answer is A
Choice A rationale
Hirschsprung’s disease is characterized by inadequate motility of part of the intestine, resulting in a mechanical obstruction. This condition is caused by the absence of ganglion cells in the affected segment of the intestine, leading to a lack of peristalsis and subsequent obstruction.
Choice B rationale
Encopresis is a condition characterized by the repeated passage of feces into inappropriate places, such as clothing or the floor. It is not associated with inadequate motility of the intestine or mechanical obstruction.
Choice C rationale
Pyloric stenosis is a condition characterized by the narrowing of the pylorus, which leads to obstruction of the passage of food from the stomach to the small intestine. It is not associated with inadequate motility of the intestine.
Choice D rationale
Enterocolitis is an inflammation of the intestine and colon. It is not associated with inadequate motility of the intestine or mechanical obstruction.

Correct Answer is A
Explanation
Choice A rationale
Projectile vomiting is a hallmark symptom of pyloric stenosis. It occurs due to the obstruction at the pylorus, causing forceful expulsion of stomach contents. This symptom typically appears in infants between 3 to 6 weeks of age.
Choice B rationale
A rigid abdomen is not a typical symptom of pyloric stenosis. It may indicate other abdominal issues, such as peritonitis or bowel obstruction.
Choice C rationale
Red currant jelly stools are associated with intussusception, not pyloric stenosis. Intussusception involves the telescoping of one part of the intestine into another, leading to bowel obstruction and characteristic stool appearance.
Choice D rationale
Distended neck veins are not related to pyloric stenosis. This symptom is more commonly associated with cardiac conditions or severe respiratory distress.
Correct Answer is ["A","C","E"]
Explanation
Choice A rationale
Daytime symptoms occurring more than twice a week is an expected finding in mild persistent asthma. This indicates that the asthma is not well-controlled and requires regular use of a controller medication.
Choice B rationale
Nighttime symptoms occurring approximately twice a month is more characteristic of intermittent asthma, not mild persistent asthma.
Choice C rationale
Minor limitations with normal activity are expected in mild persistent asthma. This indicates that the asthma is affecting the child’s daily activities to some extent.
Choice D rationale
Symptoms that are continuous throughout the day are indicative of severe persistent asthma, not mild persistent asthma.
Choice E rationale
A peak expiratory flow (PEF) greater than or equal to 80% of the predicted value is an expected finding in mild persistent asthma. This indicates that the child’s lung function is relatively well-preserved.
