QUESTIONS 1–150
QUESTION 1
A 52-year-old patient reports intermittent epigastric discomfort that improves
after eating but returns several hours later. The patient has been taking naproxen
,daily for chronic knee pain. Which diagnosis should receive the greatest
consideration?
A. Acute pancreatitis
B. Peptic ulcer disease
C. Acute cholecystitis
D. Irritable bowel syndrome
🔴 Correct Answer: B. Peptic ulcer disease.
🔵 Explanation: Epigastric pain associated with meals and chronic NSAID exposure
strongly suggests peptic ulcer disease. NSAIDs impair gastric mucosal defenses and
increase ulcer risk.
QUESTION 2
A patient with suspected gastroesophageal reflux disease reports progressive
dysphagia to solid foods. What is the most appropriate next step?
A. Begin an antacid and reassess in 6 months
B. Order diagnostic endoscopic evaluation
C. Diagnose functional dyspepsia
D. Recommend increased dietary fiber only
🔴 Correct Answer: B. Order diagnostic endoscopic evaluation.
🔵 Explanation: Progressive dysphagia is an alarm feature requiring evaluation for
structural disease such as stricture, malignancy, or other esophageal pathology.
QUESTION 3
A 28-year-old patient has recurrent abdominal pain associated with defecation
and alternating constipation and diarrhea. There is no weight loss, bleeding,
anemia, fever, or nocturnal diarrhea. Which diagnosis is most consistent?
A. Crohn disease
B. Colorectal malignancy
C. Irritable bowel syndrome
D. Ulcerative colitis
🔴 Correct Answer: C. Irritable bowel syndrome.
🔵 Explanation: Recurrent abdominal pain associated with defecation and altered
bowel habits without alarm features is characteristic of IBS.
QUESTION 4
,A patient with chronic diarrhea has weight loss, nocturnal symptoms, anemia, and
intermittent hematochezia. Which finding most strongly argues against
uncomplicated IBS?
A. Abdominal discomfort
B. Altered bowel frequency
C. Nocturnal diarrhea
D. Symptoms associated with stress
🔴 Correct Answer: C. Nocturnal diarrhea.
🔵 Explanation: Nocturnal diarrhea is an alarm feature suggesting an organic
disorder such as inflammatory bowel disease, infection, or malignancy rather than
uncomplicated IBS.
QUESTION 5
A 24-year-old patient develops right lower-quadrant abdominal pain after several
hours of vague periumbilical discomfort. The patient now has anorexia and
nausea. Which diagnosis is most likely?
A. Acute appendicitis
B. Diverticulitis
C. Renal colic
D. IBS
🔴 Correct Answer: A. Acute appendicitis.
🔵 Explanation: Migration of pain from the periumbilical area to the right lower
quadrant with anorexia and nausea is a classic pattern of appendicitis.
QUESTION 6
A patient has right upper-quadrant pain, fever, nausea, and a positive Murphy sign
after eating a fatty meal. Which diagnosis is most likely?
A. Acute cholecystitis
B. Acute pancreatitis
C. Appendicitis
D. Gastritis
🔴 Correct Answer: A. Acute cholecystitis.
🔵 Explanation: Right-upper-quadrant pain, fever, and a positive Murphy sign
strongly support acute inflammation of the gallbladder.
QUESTION 7
, A patient with suspected acute pancreatitis reports severe epigastric pain radiating
to the back with vomiting. Which laboratory test is particularly useful?
A. Serum lipase
B. Serum ferritin
C. TSH
D. Hemoglobin A1c
🔴 Correct Answer: A. Serum lipase.
🔵 Explanation: Serum lipase is a key laboratory test in suspected acute pancreatitis
and generally remains elevated longer than amylase.
QUESTION 8
A patient develops profuse watery diarrhea after completing a course of
clindamycin. Which diagnosis should be prioritized?
A. IBS
B. Clostridioides difficile infection
C. Lactose intolerance
D. Crohn disease
🔴 Correct Answer: B. Clostridioides difficile infection.
🔵 Explanation: Recent antibiotic exposure followed by significant watery diarrhea is
highly concerning for C. difficile infection.
QUESTION 9
A patient with chronic constipation has progressive abdominal distention,
vomiting, inability to pass stool or flatus, and severe abdominal pain. What is the
priority?
A. Increase dietary fiber
B. Start polyethylene glycol
C. Evaluate urgently for bowel obstruction
D. Reassure the patient
🔴 Correct Answer: C. Evaluate urgently for bowel obstruction.
🔵 Explanation: Obstipation, vomiting, distention, and severe pain are concerning
for mechanical obstruction and require urgent evaluation rather than routine
constipation management.
