32
Q

A 25-year-old man is severely injured in a motor vehicle collision. After 6 weeks of total parenteral nutrition (intravenous feeding), the stomach
and small intestines have atrophied substantially. A lack of which of the following gastrointestinal hormones is most likely to account for the atrophy in this man?

A) Cholecystokinin
B) Gastrin
C) Glucose-dependent insulinotropic peptide
D) Motilin
E) Secretin
A

B) Gastrin is secreted mainly by the G-cells of the antrum of the stomach.

The primary actions of gastrin are (1) stimulation of gastric acid secretion and (2) stimulation of mucosal growth throughout the gastrointestinal tract.

33
Q

A 43-year-old woman eats a meal consisting of 70% carbohydrate, 20% protein, and 10% fat. Six hours after consuming the meal, intense peristaltic contractions travel from the stomach to the colon over a period of about 90 minutes. Which of the following hormones is most likely to mediate the intense peristaltic contractions in this woman?

A) Cholecystokinin
B) Gastrin
C) Glucose-dependent insulinotropic peptide
D) Motilin
E) Secretin
A

D) Motilin is secreted by the duodenum and jejunum during fasting, and the only known function of this hormone is to increase gastrointestinal
motility. Motilin is released cyclically and stimulates waves of gastrointestinal motility called interdigestive myoelectric complexes (or migrating motility complexes) that move through the stomach and small intestine every 90 minutes in a person who has fasted.

34
Q

Dietary fat can cause the release of all gastrointestinal hormones EXCEPT one. Which one is the EXCEPTION?

A) Cholecystokinin
B) Gastrin
C) Glucose-dependent insulinotropic peptide
D) Motilin
E) Secretin
A

B) Gastrin is secreted in response to vagal stimulation as well as stimuli associated with ingestion of a meal, such as distention of the stomach and the breakdown products of proteins. However, fat does not cause the release of gastrin as it does with other gastrointestinal
hormones.

35
Q

Biopsies are taken from the antral and duodenal mucosa of a 48-year- old woman. Which of the following hormones can be found in tissue homogenates from both locations?

A) Secretin
B) Gastrin
C) Cholecystokinin (CCK)
D) Motilin
E) Glucose-dependent insulinotropic peptide (GIP)
A

B) Gastrin is the only gastrointestinal hormone listed that is produced and stored in the antrum of the stomach. All five gastrointestinal hormones are produced and stored in the duodenum and jejunum.

36
Q

Oral administration of a histamine H2 receptor antagonist is most likely to cause which of the following changes in the ability of gastrin, acetylcholine, and histamine to stimulate gastric acid
secretion?

A) Gastrin increased; acetylcholine increased; histamine increased
B) Gastrin decreased; acetylcholine decreased; histamine decreased
C) Gastrin no change; acetylcholine decreased; histamine no change
D) Gastrin increased; acetylcholine decreased; histamine decreased
E) Gastrin decreased; acetylcholine no change; histamine decreased

A

B) The three secretagogues for gastric acid secretion are gastrin, histamine, and acetylcholine. These secretagogues have a synergistic or multiplicative action on acid secretion, which means that blocking the action of one secretagogue will cause the other secretagogues to be less effective. Hence, blocking the actions of histamine with an H2 antagonist causes gastrin and acetylcholine to be less effective in stimulating acid secretion.

37
Q

A 34-year-old physician visits a gastroenterologist because of nausea, abdominal pain, and diarrhea. The physician was exposed to raw sewage and polluted water on a recent mission trip to an underprivileged area. The gastroenterologist administers a proton
pump inhibitor and tetracycline. All the symptoms go away in 2 weeks. Which of the following best describes the condition for which the physician was treated?

A) Excessive alcohol consumption
B) Ulcerative colitis
C) Psychogenic diarrhea
D) Posttraumatic stress syndrome
E) Helicobacter pylori infection
A

E) Helicobacter pylori is endemic in many underprivileged areas of the world. At least 75% of persons with peptic ulcers have been found to have chronic infection of the terminal portions of the gastric mucosa and initial portions of the duodenal mucosa, most often caused by the bacterium H. pylori. Once this infection begins, it can last a lifetime unless it is eradicated by antibacterial therapy.

38
Q

A 10-year-old boy consumes a cheeseburger, fries, and a chocolate shake. The meal stimulates the release of several gastrointestinal hormones. The presence of fat, carbohydrate, or protein in the duodenum stimulates the release of which hormone from the duodenal mucosa?

A) Cholecystokinin (CCK)
B) Glucose-dependent insulinotropic peptide (GIP)
C) Gastrin
D) Motilin
E) Secretin
A

B) GIP is the only gastrointestinal hormone released by all three major foodstuffs (fats, proteins, and carbohydrates). The presence of fat and protein in the small intestine stimulates the release of CCK, but carbohydrates do not stimulate its release.

39
Q

The proenzyme pepsinogen is secreted mainly from which of the following structures?

A) Acinar cells of the pancreas
B) Ductal cells of the pancreas
C) Epithelial cells of the duodenum
D) Gastric glands of the stomach

A
  1. D) Pepsinogen is the precursor of the enzyme pepsin. Pepsinogen is secreted from the peptic or chief cells of the gastric gland (also called the oxyntic gland).
40
Q

Which hormone is released by the presence of fat and protein in the small intestine and has a major effect in decreasing gastric emptying?

A) Cholecystokinin
B) Glucose-dependent insulinotropic peptide
C) Gastrin
D) Motilin
E) Secretin
A

Cholecystokinin (CCK) is the only gastrointestinal hormone that inhibits gastric emptying under physiological conditions.
