Chapter 36: Alterations of Digestive Function

Chapter 36: Alterations of Digestive Function 1. Which of the following types of diarrhea would most likely occur with a bacterial GI infection? a. Osmotic b. Secretory c. Hypotonic d. Motility ANS: B Bacterial infections lead to secretory diarrhea. A nonabsorbable substance in the intestine leads to osmotic diarrhea. Hypotonic diarrhea is not a form of diarrhea. Food is not mixed properly, digestion and absorption are impaired, and motility is increased, leading to motility diarrhea. REF: p. 908 2. A 20-year-old recently diagnosed with lactose intolerance eats an ice cream cone and develops diarrhea. This diarrhea can be classified as diarrhea. a. osmotic b. secretory c. hypotonic d. motility ANS: A A nonabsorbable substance in the intestine leads to osmotic diarrhea. Infections lead to secretory diarrhea. Hypotonic diarrhea is not a form of diarrhea. Food is not mixed properly, digestion and absorption are impaired, and motility is increased leading to motility diarrhea. REF: p. 908 3. Assuming that midline epigastric pain is caused by a stimulus acting on an abdominal organ, the pain felt is classified as: a. visceral. b. somatic. c. parietal. d. referred. ANS: A Visceral pain arises from a stimulus (distention, inflammation, and ischemia) acting on an abdominal organ. Somatic is a form of parietal pain. Parietal pain, from the parietal peritoneum, is more localized and intense than visceral pain, which arises from the organs themselves. Referred pain is visceral pain felt at some distance from a diseased or affected organ.
