Question 1
Clinical Scenario
A 54-year-old man is admitted with a history of
gastroesophageal reflux disease (GERD). He reports persistent
heartburn despite using over-the-counter antacids. The
provider prescribes pantoprazole 40 mg orally once daily. The
nurse reviews the medication administration schedule. Vital
signs are stable. The patient asks when he should take the
medication for the best effect.
Question Stem
Which instruction should the nurse provide regarding the
administration of pantoprazole?
A. Take the medication immediately after each meal.
,B. Take the medication at bedtime with milk.
C. Take the medication 30 to 60 minutes before breakfast.
D. Take the medication only when heartburn symptoms occur.
Correct Answer
Correct Answer: C. Take the medication 30 to 60 minutes
before breakfast.
Detailed Rationale
Pantoprazole is a proton pump inhibitor (PPI) that irreversibly
inhibits the gastric hydrogen-potassium ATPase pump in parietal
cells, significantly reducing gastric acid secretion. PPIs are most
effective when taken 30–60 minutes before the first meal of
the day because food stimulates proton pumps to become
active, allowing the medication to bind and inactivate them.
This timing maximizes acid suppression and promotes healing
of erosive esophagitis and symptom relief in GERD.
Option A is incorrect because taking pantoprazole after meals
decreases its effectiveness; the drug works best before proton
pumps are activated by food.
Option B is incorrect because bedtime administration is not
routinely recommended unless specifically prescribed for
certain conditions. Milk does not improve absorption or
effectiveness.
,Option D is incorrect because pantoprazole is not intended for
immediate symptom relief. Unlike antacids, PPIs require
consistent daily administration for optimal therapeutic benefit.
The nurse should also instruct the patient to swallow delayed-
release tablets whole, avoid crushing or chewing them,
continue lifestyle modifications such as weight management
and avoiding trigger foods, and notify the provider if symptoms
persist or gastrointestinal bleeding develops. Long-term PPI
therapy may require monitoring for vitamin B12 deficiency,
hypomagnesemia, fractures, and Clostridioides difficile infection
risk.
Learning Objectives
After completing this question, the learner should be able to:
• Explain the proper timing of proton pump inhibitor
administration.
• Differentiate PPIs from antacids regarding onset of action.
• Provide patient teaching to maximize therapeutic
effectiveness.
Medication Safety Focus
Medication administration
Question 2
, Clinical Scenario
A 67-year-old woman is hospitalized with a bleeding gastric
ulcer. The provider prescribes sucralfate 1 g orally four times
daily. Her medication list also includes levothyroxine,
ciprofloxacin, calcium carbonate, and a daily multivitamin. The
nurse reviews the medication schedule before administration.
Question Stem
Which nursing action is most appropriate when administering
sucralfate?
A. Administer sucralfate at the same time as all other oral
medications.
B. Give sucralfate with milk to reduce stomach irritation.
C. Separate sucralfate from other oral medications by at least 2
hours.
D. Crush the tablet and mix it with antacid before
administration.
Correct Answer
Correct Answer: C. Separate sucralfate from other oral
medications by at least 2 hours.
Detailed Rationale
Sucralfate forms a protective barrier over gastric and duodenal
ulcers by binding to ulcerated tissue in an acidic environment.
