1. Which of the following medications is commonly used to treat
Helicobacter pylori infection?
- A. Metronidazole
- B. Amoxicillin

- D. All of the above
ANS: D. All of the above

©/2025
,amoxicillin) and a proton pump inhibitor (omeprazole) to reduce
stomach acid and enhance antibiotic efficacy.
2. What is the primary mechanism of action of proton pump
inhibitors (PPIs) in the treatment of gastroesophageal reflux
disease (GERD)?
- A. Neutralizing stomach acid
- B. Blocking H2 receptors
- C. Inhibiting the H+/K+ ATPase enzyme
- D. Stimulating mucus production
ANS: C. Inhibiting the H+/K+ ATPase enzyme
Rationale: Proton pump inhibitors inhibit the H+/K+ ATPase
enzyme in the gastric parietal cells, reducing gastric acid secretion
and providing relief from GERD symptoms.
Fill-in-the-Blank Questions
3. __________ is the inflammation of the liver often caused by
viral infections, alcohol abuse, or autoimmune diseases.
ANS: Hepatitis

can become inflamed and result in a condition called
diverticulitis.
ANS: Diverticula
Rationale: Diverticula are small pouches that form in the wall

characterized by abdominal pain, bloating, and altered bowel
habits without underlying inflammation or structural
abnormalities.

, 6. True or False: Nonsteroidal anti-inflammatory drugs
(NSAIDs) can cause peptic ulcers by inhibiting the production of
protective gastric mucus.
ANS: True
Rationale: NSAIDs can cause peptic ulcers by inhibiting the
enzyme cyclooxygenase, reducing the production of
prostaglandins, which are necessary for the production of
protective gastric mucus.
Multiple Response Questions

disease? (Select all that apply)
