Deck 28: Medical Nutrition Therapy for Upper Gastrointestinal Tract Disorders

Question 1

A patient with gastroparesis may benefit by which of these drugs?

A)Metoclopramide
B)Aspirin
C)Acarbose
D)Simethicone

Answer 1

A
Metoclopramide is prokinetic agent.It increases the contractility of the stomach and shortens gastric emptying time.

Question 2

Which of the following statements is NOT associated with Helicobacter pylori?

A)H.pylori increases the risk of atrophic gastritis and gastric cancer.
B)H.pylori is a viral infection found in the intestine.
C)H.pylori is a bacterial infection found in the gastric mucosa.
D)H.pylori infection may be treated with antibiotics and acid suppression therapies.

Answer 2

B
Helicobacter pylori are gram-negative bacteria that have been associated with increased risk of atrophic gastritis, peptic ulcer, and gastric cancer.Treatment of an infection usually involves a combination of antibiotics and acid suppression medications.

Question 3

What nutrient has been associated with prevention of GI cancers?

A)Vitamin C
B)Red wine
C)Selenium
D)Protein

Answer 3

C
Whereas consumption of fruits, vegetables, and selenium appears to have a modest role in the prevention of GI cancers, alcohol consumption and being overweight increase the risk.

Question 4

What is the major difference between gastric and duodenal ulcers?

A)Gastric ulcers can develop with low acid output, and duodenal ulcers develop with high acid secretions.
B)Gastric ulcers develop with high acid secretion, and duodenal ulcers develop with low acid output.
C)H.pylori is the primary cause of gastric ulcers.
D)Gastric ulcers are treated with proton pump inhibitors, and duodenal ulcers are treated with H2-receptor antagonists.

Question 5

What symptoms of dumping syndrome follow the total or subtotal removal of the stomach?

A)Nausea, abdominal cramping, and diarrhea
B)Elevated blood pressure, headache, and substernal pain
C)Heartburn, vomiting blood, and hypoglycemia
D)Decreased saliva production, steatorrhea, and bloating

C)Fundoplication
D)Roux-en-Y procedure

Question 13

What causes the hypoglycemia that occurs after meals in patients who have had a gastrectomy?
