Final answer:
The nurse should expect several findings in an infant with intussusception, including currant jelly-like stools, abdominal distension, sudden, severe abdominal pain, high-pitched crying, and visible peristalsis.
Step-by-step explanation:
Intussusception is a serious condition that occurs when one portion of the intestine telescopes into another, causing a blockage. The nurse should expect several findings in an infant with intussusception, including currant jelly-like stools, which are bloody and mucus-filled due to the intestinal obstruction.
Other findings may include abdominal distension caused by the blockage, sudden, severe abdominal pain due to the intestine telescoping, and high-pitched crying associated with distress and discomfort.
Finally, visible peristalsis may be observed, which is the visible movement of the intestines beneath the skin.
