20 ATI & NGN-Style GI Medication Safety
MCQs with Rationales
Question 1
Clinical Scenario
A 45-year-old client with gastroesophageal reflux disease (GERD)
has been prescribed omeprazole 20 mg orally once daily. The nurse
is providing medication education before discharge.
Question Stem
Which statement by the client indicates correct understanding of
the medication?
A. "I will take this medication immediately after meals."
B. "I should take this medication before breakfast."
C. "I will stop taking it as soon as my symptoms improve."
D. "I should crush the capsule before swallowing."
Correct Answer
, Correct Answer: B. "I should take this medication before
breakfast."
Detailed Rationale
Omeprazole is a proton pump inhibitor (PPI) that suppresses gastric
acid secretion by irreversibly inhibiting the hydrogen-potassium
ATPase pump in gastric parietal cells. For optimal effectiveness,
PPIs should generally be taken 30–60 minutes before meals,
commonly before breakfast. This timing allows the medication to
inhibit active proton pumps stimulated by food intake.
Option A is incorrect because administration after meals reduces
therapeutic effectiveness. Option C is incorrect because GERD
treatment often requires completion of the prescribed regimen even
if symptoms improve. Premature discontinuation can lead to
symptom recurrence. Option D is incorrect because enteric-coated
capsules should not be crushed, as this destroys the protective
coating and may reduce efficacy.
The nurse should educate the client about consistent
administration timing, avoiding abrupt discontinuation without
provider guidance, and reporting persistent symptoms such as
dysphagia, gastrointestinal bleeding, or severe abdominal pain.
Long-term PPI therapy may increase risks of fractures, vitamin B12
deficiency, and hypomagnesemia, requiring monitoring in some
clients.
Learning Objective
After completing this question, the learner should be able to:
• Explain proper administration of proton pump inhibitors.
