Answer to Question 1

Correct Answer: 2
Rationale 1: Flatus is largely air and the by-products of the digestion of carbohydrates.
Rationale 2: Mass peristalsis involves a wave of powerful muscular contraction that moves over large areas of the colon. Mass peristalsis most commonly occurs after eating, stimulated by the presence of food in the stomach and small intestine. In adults, mass peristaltic waves occur only a few times a day.
Rationale 3: Haustral churning involves movement of the chyme back and forth within the haustra. This action aids in the absorption of water and moves the contents forward to the next haustra.
Rationale 4: Peristalsis is wavelike movement produced by the circular and longitudinal muscle fibers of the intestinal walls; it propels the intestinal contents forward.

Answer to Question 2

Correct Answer: 1
Rationale 1: Stool that is pale in color is seen in those who ingest a diet high in milk and milk products and low in meat.
Rationale 2: Eating a diet low in fruits and vegetables will not produce pale stool.
Rationale 3: Using laxatives routinely will not produce pale stool.
Rationale 4: Drinking 8 to 10 8-ounce glasses of water each day will not produce pale stool.
