Question 1
Clinical Scenario
A 68-year-old man is admitted with gastroesophageal reflux
disease (GERD). His history includes osteoporosis, chronic
kidney disease stage 3, and hypertension. Home medications
include lisinopril and calcium carbonate as needed for
heartburn. The provider prescribes pantoprazole 40 mg orally
once daily. The nurse is developing a discharge teaching plan.
Question Stem
Which statement by the patient indicates the need for further
teaching regarding pantoprazole therapy?
,A. "I'll take this medication about 30 to 60 minutes before
breakfast."
B. "If my symptoms improve, I'll stop taking the medication
without notifying my provider."
C. "I should notify my provider if I develop persistent diarrhea."
D. "Long-term use may increase my risk for bone fractures."
Correct Answer
Correct Answer: B. "If my symptoms improve, I'll stop taking
the medication without notifying my provider."
Detailed Rationale
Pantoprazole is a proton pump inhibitor (PPI) that irreversibly
inhibits the gastric hydrogen-potassium ATPase pump,
producing profound suppression of gastric acid secretion. PPIs
are most effective when taken approximately 30 to 60 minutes
before the first meal of the day because proton pumps become
activated with food intake. Therapy should be continued for the
prescribed duration, even if symptoms improve early. Abrupt
discontinuation without provider guidance may lead to
symptom recurrence and rebound acid hypersecretion.
Option A is correct patient teaching because administration
before breakfast maximizes acid suppression.
,Option C is appropriate because persistent diarrhea may
indicate Clostridioides difficile infection, a recognized
complication associated with prolonged acid suppression.
Option D is also correct. Long-term PPI therapy has been
associated with decreased calcium absorption, osteoporosis-
related fractures, hypomagnesemia, vitamin B12 deficiency, and
possible kidney complications. Patients at higher fracture risk
should receive appropriate monitoring and preventive
measures.
From a nursing perspective, medication adherence, assessment
of symptom relief, and evaluation for adverse effects are
essential. Nurses should also review concurrent medications
because PPIs may alter absorption of drugs requiring an acidic
gastric environment.
Learning Objectives
After completing this question, the learner should be able to:
• Explain proper administration of proton pump inhibitors.
• Identify important long-term adverse effects of PPIs.
• Reinforce appropriate medication adherence.
• Recognize complications requiring provider notification.

, Question 2
Clinical Scenario
A 42-year-old woman presents to the emergency department
with hematemesis. She is diagnosed with a bleeding duodenal
ulcer. The provider prescribes an intravenous pantoprazole
infusion. Assessment findings include BP 90/56 mm Hg, HR
116/min, RR 22/min, and hemoglobin 8.4 g/dL.
Question Stem
Which nursing action is the highest priority after initiating the
pantoprazole infusion?
A. Encourage oral fluids.
B. Monitor for continued signs of gastrointestinal bleeding.
C. Administer an antacid every 2 hours.
D. Place the patient in a high-Fowler position after meals.
Correct Answer
Correct Answer: B. Monitor for continued signs of
gastrointestinal bleeding.
Detailed Rationale
Pantoprazole reduces gastric acid secretion, promoting clot
stabilization and ulcer healing in upper gastrointestinal
