TESTING QUESTIONS AND CORRECT
ANSWERS WITH DETAILED
EXPLANATIONS|GUARANTEED PASS.
GASTROINTESTINAL
Prepare confidently for the ATI Med Surg Gastrointestinal final Exam
with targeted questions covering esophageal disorders, gastric and
duodenal disorders, inflammatory bowel disease (Crohn’s,
ulcerative colitis), diverticular disease, appendicitis. This study
guide helps reinforce essential medical-surgical nursing concepts
and supports effective ATI exam preparation. Designed for nursing
and healthcare students.
MULTIPLE CHOICE.
Subsection 1: Esophageal & Gastric Disorders (Questions 1–
15)
1. A patient with gastroesophageal reflux disease (GERD)
reports worsening heartburn. Which of the following should
the nurse include in patient teaching?
A) Lie down immediately after meals
B) Avoid eating within 3 hours of bedtime
C) Increase intake of peppermint tea
D) Eat large, heavy meals to reduce gastric emptying time
, Page 2 of 46
Answer: B. Avoid eating within 3 hours of bedtime
Explanation: Patients with GERD should avoid lying down within
3 hours of eating to prevent reflux. Small, frequent meals are
recommended; large meals increase gastric pressure.
Peppermint relaxes the lower esophageal sphincter (LES) and
should be avoided.
2. A patient with a hiatal hernia is experiencing reflux
symptoms. Which instruction by the nurse is most
appropriate?
A) Sleep with the head of the bed elevated
B) Bend over frequently to stretch the diaphragm
C) Wear tight-fitting clothing around the waist
D) Drink carbonated beverages to relieve bloating
Answer: A. Sleep with the head of the bed elevated
Explanation: Elevating the head of the bed uses gravity to
reduce reflux. Tight clothing and bending increase
intra-abdominal pressure and worsen reflux. Carbonated
beverages cause gastric distention and promote reflux.
3. A client with peptic ulcer disease (PUD) tests positive
for Helicobacter pylori. Which combination medication
regimen is first-line treatment?
A) Antacids only
B) Proton pump inhibitor (PPI) + amoxicillin + clarithromycin
(triple therapy)
C) H2 receptor antagonist alone
D) Bismuth subsalicylate only
, Page 3 of 46
Answer: B. Proton pump inhibitor (PPI) + amoxicillin +
clarithromycin (triple therapy)
Explanation: Triple therapy (PPI + two antibiotics) is standard
for H. pylori eradication. Quadruple therapy (PPI + bismuth +
metronidazole + tetracycline) is used for resistant cases.
4. A patient is admitted with acute gastritis after heavy
alcohol use. Which assessment finding is most concerning?
A) Epigastric pain
B) Nausea and vomiting
C) Hematemesis (coffee-ground emesis) or melena
D) Abdominal bloating
Answer: C. Hematemesis (coffee-ground emesis) or melena
Explanation: Coffee-ground emesis or melena indicates upper
GI bleeding from erosive gastritis. This requires immediate
intervention (IV fluids, blood transfusion, endoscopy).
5. A patient is prescribed omeprazole (Prilosec) for GERD.
The nurse should instruct the patient to take this
medication:
A) With meals
B) At bedtime only
C) 30-60 minutes before breakfast
D) When heartburn occurs
Answer: C. 30-60 minutes before breakfast
Explanation: PPIs are most effective when taken on an empty
stomach 30-60 minutes before a meal (preferably before
, Page 4 of 46
breakfast). They inhibit the proton pump, reducing acid
secretion.
6. A patient with a gastric ulcer reports that pain is relieved
by eating. This pattern is typical of:
A) Duodenal ulcer (pain relieved by food)
B) Gastric ulcer (pain often worsens with food)
C) Gastritis
D) GERD
Answer: A. Duodenal ulcer (pain relieved by food)
Explanation: Duodenal ulcers typically cause pain that is
relieved by food (buffering effect). Gastric ulcers often cause
pain that is aggravated by eating.
7. A patient had a gastrectomy. The nurse teaches the patient
to eat small, frequent meals to prevent:
A) Dumping syndrome
B) Constipation
C) Diarrhea
D) Reflux esophagitis
Answer: A. Dumping syndrome
Explanation: After gastrectomy, rapid gastric emptying of
hypertonic chyme into the small intestine causes dumping
syndrome (nausea, cramping, diarrhea, hypotension). Small,
frequent, low-carbohydrate meals help prevent it.
8. The nurse is assessing a patient with suspected
peritonitis. Which finding is most indicative?
A) Rebound tenderness and rigid abdomen
