Rationales | Nursing Exam Prep
Question 1
Difficulty: Easy
Clinical Scenario
A 46-year-old woman is admitted with severe gastroesophageal
reflux disease (GERD). She reports frequent heartburn that
worsens after meals and at night. The provider prescribes
pantoprazole 40 mg orally once daily. During medication
administration, the nurse assesses the client's understanding of
the medication.
Question Stem
Which statement by the client indicates a correct understanding
of pantoprazole therapy?
A. "I should take this medication about 30 to 60 minutes before
breakfast."
,B. "I will stop taking the medication as soon as my symptoms
improve."
C. "I should crush the tablet if I have difficulty swallowing it."
D. "I will take this medication only when I experience
heartburn."
Correct Answer
Correct Answer: A. "I should take this medication about 30 to
60 minutes before breakfast."
Detailed Rationale
Pantoprazole is a proton pump inhibitor (PPI) that irreversibly
inhibits the gastric H+/K+-ATPase enzyme within parietal cells,
reducing gastric acid secretion. PPIs are most effective when
administered 30 to 60 minutes before the first meal of the day,
allowing the medication to inhibit actively functioning proton
pumps stimulated by food intake. This timing maximizes
therapeutic effectiveness and promotes healing of esophagitis
and gastric ulcers.
Option B is incorrect because GERD often requires a full
prescribed course of therapy. Discontinuing treatment
prematurely can lead to symptom recurrence and incomplete
healing.
Option C is incorrect because delayed-release pantoprazole
tablets should not be crushed, chewed, or split unless a specific
,formulation permits it. Altering the tablet may destroy its
protective coating and reduce effectiveness.
Option D is incorrect because PPIs are maintenance
medications, not immediate-relief agents. They require
consistent daily administration and are not intended for "as-
needed" symptom relief.
The nurse should also educate the client about lifestyle
modifications such as avoiding late-night meals, elevating the
head of the bed, limiting trigger foods, and reporting persistent
symptoms or gastrointestinal bleeding. Long-term therapy
warrants monitoring for nutrient deficiencies and other adverse
effects.
Learning Objectives
After completing this question, the learner should be able to:
• Explain the proper timing of proton pump inhibitor
administration.
• Differentiate maintenance therapy from symptom-relief
medications.
• Educate patients on safe administration of pantoprazole.
• Recognize nursing considerations for long-term PPI
therapy.

Question 2
Difficulty: Easy
Clinical Scenario
A 72-year-old man with chronic kidney disease is prescribed
magnesium hydroxide for occasional constipation. His
laboratory results show a serum creatinine of 2.8 mg/dL. During
medication reconciliation, the nurse reviews the prescription
before administration.
Question Stem
Which nursing action is the priority?
A. Administer the medication with a full glass of water.
B. Encourage increased dietary fiber intake.
C. Notify the provider because magnesium-containing laxatives
may accumulate in renal impairment.
D. Administer the medication at bedtime.
Correct Answer
Correct Answer: C. Notify the provider because magnesium-
containing laxatives may accumulate in renal impairment.
