Answer to Question 1

ANS: D
Intussusception occurs when a proximal section of the bowel telescopes into a more distal segment, pulling the mesentery with it. The mesentery is compressed and angled, resulting in lymphatic and venous obstruction. Invagination of one segment of bowel within another is the definition of intussusception, not atresia, stenosis, or herniation.

Answer to Question 2

ANS: C
The diagnosis of pyloric stenosis is often made after the history and physical examination. The olive-like mass is easily palpated when the stomach is empty, the infant is quiet, and the abdominal muscles are relaxed. Abdominal rigidity and substernal retraction are usually not present. The upper abdomen, not lower abdomen, is distended.
