Subtopic 1: Proton Pump Inhibitors (PPIs) –
Mechanism, Indications, and Patient Education
Question 1
A nurse is educating a patient prescribed omeprazole for gastroesophageal
reflux disease (GERD). Which patient statement indicates a need for further
teaching?
A. "I should take this medication 30 minutes before a meal."
B. "I can stop the medication once I feel better."
C. "This medication helps decrease the amount of acid my stomach makes."
D. "Long-term use can increase my risk of bone fractures."
Correct Answer: B
Rationale: PPIs should be taken as prescribed, even if symptoms improve.
Stopping abruptly may lead to rebound acid hypersecretion. The other
statements are accurate and reflect appropriate understanding.
Question 2
Which of the following is a common long-term adverse effect of prolonged
PPI therapy?
A. Increased saliva production
B. Elevated white blood cell count
C. Vitamin B12 deficiency
D. Hyperthyroidism
Correct Answer: C
, 3
Rationale: Long-term PPI use can impair gastric acid production, leading to
decreased absorption of vitamin B12 and iron. This may result in
deficiencies.
Question 3
Which medication would most likely interact negatively with omeprazole due
to reduced absorption?
A. Acetaminophen
B. Metoprolol
C. Ketoconazole
D. Furosemide
Correct Answer: C
Rationale: Ketoconazole requires an acidic environment for proper
absorption. PPIs reduce stomach acidity, potentially decreasing the
effectiveness of drugs like ketoconazole.
Question 4
A client taking pantoprazole IV for a bleeding ulcer asks why the drug is
administered via IV route initially. The best nurse response is:
A. "IV pantoprazole acts slower, so it's gentler on your system."
B. "Oral pantoprazole can cause ulcers."
C. "IV delivery ensures rapid acid suppression needed in acute bleeding
situations."
D. "IV pantoprazole works directly on the ulcer site."
Correct Answer: C
Rationale: In acute gastrointestinal bleeding, IV PPIs provide faster acid
suppression, stabilizing clots and promoting mucosal healing more efficiently
than oral forms.

Question 5
Which of the following nursing actions is most important when administering
a PPI to a patient with a history of osteoporosis?
A. Monitor liver enzymes monthly
B. Encourage caffeine intake
C. Ensure calcium and vitamin D supplementation
D. Recommend increased alcohol intake
Correct Answer: C
Rationale: Long-term PPI use is associated with reduced calcium absorption
and increased fracture risk. Supplementing with calcium and vitamin D is
essential in at-risk populations.
Question 6
Esomeprazole acts by:
A. Blocking H2 receptors in the stomach lining
B. Increasing mucosal bicarbonate secretion
C. Inhibiting the hydrogen-potassium ATPase enzyme system
D. Neutralizing existing stomach acid
Correct Answer: C
Rationale: PPIs like esomeprazole irreversibly inhibit the hydrogen-potassium
ATPase enzyme in gastric parietal cells, which reduces acid production.
Question 7
A nurse should hold a prescribed dose of lansoprazole if the patient is:
A. Nauseated
