Section 1: Esophageal Disorders (Questions 1–25)
1. A 45-year-old male presents with a 3-month history of
heartburn that occurs after meals and when lying down. He
reports relief with over-the-counter antacids. Which part of
the PQRSTU method is designed to acquire information
about what makes the symptoms worse?
A. T
B. S
C. Q
D. P
Correct Answer: D. P
,Rationale: In the PQRSTU method, P stands for provocative
or palliative, which assesses what makes the symptoms
better or worse. T refers to timing, S refers to severity, and
Q refers to quality of pain.
2. A patient with gastroesophageal reflux disease (GERD) is
prescribed omeprazole. Which instruction is most
important?
A. Take with food
B. Take on an empty stomach
C. Take at bedtime
D. Take with antacids
Correct Answer: B. Take on an empty stomach
Rationale: Proton pump inhibitors like omeprazole should
be taken 30–60 minutes before breakfast for optimal
effectiveness. They work by irreversibly inhibiting the
hydrogen-potassium ATPase pump in gastric parietal cells.
3. A 55-year-old female presents with difficulty swallowing
solid foods that has progressed to liquids over 6 months.
She has a 20-year history of GERD. Which complication is
most likely?
A. Esophageal varices
B. Esophageal stricture
C. Achalasia
D. Esophageal cancer
Correct Answer: B. Esophageal stricture
Rationale: Chronic GERD can lead to esophagitis, which
causes scarring and narrowing of the esophagus, resulting
in a peptic stricture. Progressive dysphagia (solids to
liquids) is a classic presentation.
,4. Which of the following is a risk factor for Barrett's
esophagus?
A. Chronic GERD
B. Male gender
C. Age > 50
D. All of the above
Correct Answer: D. All of the above
Rationale: Barrett's esophagus is a complication of chronic
GERD characterized by intestinal metaplasia of the
esophageal epithelium. Risk factors include chronic GERD,
male gender, age > 50, Caucasian race, central obesity, and
smoking.
5. A patient with GERD is prescribed metoclopramide. What
is the purpose of this medication?
A. Reduce gastric acid secretion
B. Accelerate gastric emptying
C. Neutralize gastric acid
D. Coat the esophageal mucosa
Correct Answer: B. Accelerate gastric emptying
Rationale: Metoclopramide is a prokinetic agent that
accelerates gastric emptying and increases lower
esophageal sphincter tone, reducing reflux.
6. Which of the following lifestyle modifications is
recommended for GERD?
A. Elevating the head of the bed
B. Avoiding large meals before bedtime
C. Weight loss
D. All of the above
, Correct Answer: D. All of the above
Rationale: Lifestyle modifications for GERD include
elevating the head of the bed, avoiding meals 2–3 hours
before bedtime, weight loss, avoiding trigger foods
(caffeine, alcohol, chocolate, spicy foods), and smoking
cessation.
7. A 60-year-old male presents with progressive solid food
dysphagia and significant weight loss. He has a 30-pack-
year smoking history and drinks alcohol daily. Which
diagnosis is most concerning?
A. Esophageal stricture
B. Achalasia
C. Esophageal cancer
D. Diffuse esophageal spasm
Correct Answer: C. Esophageal cancer
Rationale: Progressive dysphagia with significant weight
loss in a patient with smoking and alcohol use is highly
suspicious for esophageal cancer. Endoscopy with biopsy is
diagnostic.
8. A patient presents with intermittent chest pain and
dysphagia. Manometry shows simultaneous, high-
amplitude contractions. What is the most likely diagnosis?
A. Achalasia
B. Diffuse esophageal spasm
C. GERD
D. Esophageal stricture
Correct Answer: B. Diffuse esophageal spasm
