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. Atresia is the absence or closure of a natural opening in the body. Stenosis is a narrowing or constriction of the diameter of a bodily passage or orifice. Herniation is the protrusion of an organ or part through connective tissue or through a wall of the cavity in which it is normally enclosed.

Answer to Question 2

ANS: D
Infants with excessive vomiting are prone to metabolic alkalosis from the loss of hydrogen ions. Potassium and chloride ions are lost with vomiting. Metabolic alkalosis, not acidosis, is likely.
