Q&A | Instant Download Pdf
1. The most common cause of gastroesophageal reflux disease
(GERD) is:
A) Excess gastric acid secretion
B) Hiatal hernia
C) Lower esophageal sphincter dysfunction
D) Gastric ulcer
Answer: C) Lower esophageal sphincter dysfunction
Rationale: GERD primarily occurs when the lower esophageal
sphincter fails to close properly, allowing gastric contents to reflux
into the esophagus.
2. Which of the following is a typical symptom of GERD?
A) Diarrhea
B) Heartburn
C) Constipation
D) Abdominal guarding
Answer: B) Heartburn
Rationale: Heartburn, a burning sensation in the chest, is the
hallmark symptom of GERD caused by acid reflux.
3. Which lifestyle modification is most effective in managing GERD?
A) High-fat diet
B) Elevating the head of the bed
C) Smoking more
D) Eating late at night
,Answer: B) Elevating the head of the bed
Rationale: Elevating the head reduces nocturnal reflux by using
gravity to prevent stomach contents from moving upward.
4. Proton pump inhibitors (PPIs) treat GERD by:
A) Neutralizing acid
B) Blocking histamine receptors
C) Inhibiting gastric acid secretion
D) Coating the esophagus
Answer: C) Inhibiting gastric acid secretion
Rationale: PPIs like omeprazole inhibit the H+/K+ ATPase pump in
parietal cells, reducing acid production.
5. The most common complication of chronic GERD is:
A) Esophageal stricture
B) Gastric perforation
C) Duodenal ulcer
D) Hepatitis
Answer: A) Esophageal stricture
Rationale: Chronic acid exposure can cause scarring and narrowing of
the esophagus, leading to strictures.
6. Barrett’s esophagus is associated with:
A) Gastric cancer
B) Chronic GERD
C) Appendicitis
D) Crohn’s disease
Answer: B) Chronic GERD
Rationale: Repeated acid exposure can cause metaplasia of
esophageal cells, increasing the risk for esophageal adenocarcinoma.
7. Which diagnostic test is considered the gold standard for
evaluating GERD?
, A) Barium swallow
B) Upper endoscopy (EGD)
C) Abdominal ultrasound
D) Colonoscopy
Answer: B) Upper endoscopy (EGD)
Rationale: EGD allows direct visualization of esophageal mucosa and
detection of erosions, ulcers, or Barrett’s changes.
8. A patient presents with epigastric pain relieved by eating. Which
condition is most likely?
A) Duodenal ulcer
B) Gastric ulcer
C) GERD
D) Appendicitis
Answer: A) Duodenal ulcer
Rationale: Duodenal ulcer pain classically improves with food intake,
unlike gastric ulcers, which often worsen with eating.
9. The most common cause of peptic ulcer disease is:
A) Helicobacter pylori infection
B) Viral infection
C) Appendicitis
D) Pancreatitis
Answer: A) Helicobacter pylori infection
Rationale: H. pylori infection disrupts the protective mucosal layer of
the stomach and duodenum, leading to ulcer formation.
10. Which medication class increases the risk of peptic ulcers?
A) Proton pump inhibitors
B) NSAIDs
C) Antacids
D) H2 blockers
