A nurse is assessing an infant who has intussusception. Which of the following manifestations should the nurse expect?

Choice A rationale Polyuria, or excessive urination, is not a characteristic symptom of intussusception. Intussusception is a condition where a segment of the intestine telescopes into an adjacent section, leading to a mechanical bowel obstruction. This condition is primarily related to the gastrointestinal system and its symptoms are focused there, not the urinary system. Choice B rationale A scaphoid abdomen, which appears sunken or concave, is typically associated with conditions causing a lack of abdominal contents, such as malnutrition or diaphragmatic hernia. In intussusception, a mass is formed by the telescoping bowel, and the resulting edema and obstruction often lead to abdominal distention, not a scaphoid appearance. The abdomen may feel full or tender. Choice C rationale Intussusception causes a compromise of blood flow to the intestinal wall, leading to inflammation and necrosis. This results in the sloughing of the intestinal mucosa and bleeding. The combination of mucus and blood in the stool creates a characteristic "currant jelly" or gelatinous red appearance. This classic sign is a direct result of the specific pathophysiological process occurring in the bowel. Choice D rationale Generalized edema, which is the accumulation of fluid throughout the body, is not a typical manifestation of intussusception. While localized edema may occur at the site of the telescoping bowel due to vascular compromise, widespread fluid retention is not a hallmark sign. Generalized edema is more commonly seen in conditions like renal failure, liver disease, or heart failure.
