NSG 5003 CHAPTER 41: ALTERATIONS
OF DIGESTIVE FUNCTION QUESTIONS
WITH SOLUTIONS
A peptic ulcer may occur in all of the following areas except the:
a. Stomach
b. Duodenum
c. Jejunum
d. Esophagus - correct-answer - ANS: C
A peptic ulcer is a break, or ulceration, in the protective mucosal lining of the
lower
esophagus, stomach, or duodenum.
Which statement is false regarding the contributing factors of duodenal ulcers?
a. Bleeding from duodenal ulcers causes hematemesis or melena.
, 2
b. Gastric emptying is slowed, causing greater exposure of the mucosa to acid.
c. The characteristic pain begins 30 minutes to 2 hours after eating when the
stomach is empty.
d. Duodenal ulcers occur with greater frequency than other types of peptic ulcers.
- correct-answer - ANS: B
Duodenal ulcers can be associated with altered mucosal defenses, rapid gastric
emptying,
elevated serum gastrin levels, or acid production stimulated by smoking.
After a partial gastrectomy or pyloroplasty, clinical manifestations that include
increased
pulse, hypotension, weakness, pallor, sweating, and dizziness are the results of
which
mechanism?
a. Anaphylactic reaction in which chemical mediators, such as histamine,
prostaglandins, and leukotrienes, relax vascular smooth muscles, causing shock
b. Postoperative hemorrhage during which a large volume of blood is lost, causing
hypotension with compensatory tachycardia
, 3
c. Concentrated bolus that moves from the stomach into the small intestine,
causing
hyperglycemia and resulting in polyuria and eventually hypovolemic shock
d. Rapid gastric emptying and the creation of a high osmotic gradient in the small
intestine, causing a sudden shift of fluid from the blood vessels to the intestinal
lumen - correct-answer - ANS: D
Dumping syndrome occurs with varying severity in 5% to 10% of individuals who
have
undergone partial gastrectomy or pyloroplasty.
Which statement is consistent with dumping syndrome?
a. Dumping syndrome usually responds well to dietary management.
b. It occurs 1 to 2 hours after eating.
c. Constipation is often a result of the dumping syndrome.
d. It can result in alkaline reflux gastritis. - correct-answer - ANS: A
Most individuals with the dumping syndrome respond well to dietary
management.
