TESTING QUESTIONS AND CORRECT
ANSWERS WITH DETAILED
EXPLANATIONS|GUARANTEED PASS.
GASTROINTESTINAL
Prepare confidently for the ATI Med Surg Gastrointestinal Practice
Exam with targeted questions covering upper and lower GI disorders,
inflammatory bowel disease, hepatitis, cirrhosis, pancreatitis,
cholecystitis, GI bleeding, cancer, surgical procedures, medications,
and nursing interventions. This study guide helps reinforce essential
medical-surgical nursing concepts and supports effective ATI exam
preparation. Suitable for nursing and healthcare students.
Section 1: Upper GI Disorders (Questions 1–15)
1. A client with gastroesophageal reflux disease (GERD) is
prescribed a proton pump inhibitor (PPI). The nurse should
instruct the client to take this medication:
A) At bedtime with a snack
B) 30 minutes before breakfast
C) With each meal
D) Only when heartburn occurs
, Page 2 of 52
Answer: B. 30 minutes before breakfast
Explanation: PPIs (omeprazole, pantoprazole) are most
effective when taken on an empty stomach approximately
30–60 minutes before the first meal of the day. This timing
maximizes the inhibition of active proton pumps.
2. The nurse is teaching a client with GERD about lifestyle
modifications. Which statement by the client indicates
understanding?
A) “I will lie down after meals to let the food settle.”
B) “I should avoid chocolate, peppermint, and caffeine.”
C) “I can eat large meals as long as I take my medication.”
D) “I will sleep on my right side to prevent reflux.”
Answer: B. “I should avoid chocolate, peppermint, and
caffeine.”
Explanation: Chocolate, peppermint, caffeine, fatty foods,
and alcohol relax the lower esophageal sphincter (LES),
worsening reflux. Clients should avoid these. Lying down
after meals, large meals, and sleeping on the right side all
increase reflux.
3. A client with peptic ulcer disease (PUD) tests positive for
Helicobacter pylori. The nurse anticipates which treatment
regimen?
A) Antacids only
B) Triple therapy (PPI + two antibiotics)
C) H2 receptor antagonist alone
D) Sucralfate monotherapy
, Page 3 of 52
Answer: B. Triple therapy (PPI + two antibiotics)
Explanation: H. pylori is treated with a combination of a PPI
and two antibiotics (e.g., amoxicillin and clarithromycin) for
10–14 days. This eradicates the infection and promotes ulcer
healing. Monotherapy is ineffective.
4. A client with a duodenal ulcer reports pain that awakens
him at night. The nurse should recommend:
A) Eating a small snack before bedtime
B) Avoiding all food after 6 PM
C) Drinking a glass of milk at bedtime
D) Taking an antacid only in the morning
Answer: A. Eating a small snack before bedtime
Explanation: Duodenal ulcer pain often occurs when the
stomach is empty (nighttime, 2–4 hours after meals). A small
snack buffers acid and may relieve pain. However, eating too
close to bedtime can worsen GERD; the client must balance
both conditions.
5. The nurse is caring for a client with a bleeding gastric
ulcer. Which finding indicates continued bleeding?
A) Hypotension and tachycardia
B) Decreased BUN
C) Increased hemoglobin and hematocrit
D) Warm, dry skin
Answer: A. Hypotension and tachycardia
Explanation: Hypotension and tachycardia are signs of
, Page 4 of 52
hypovolemia from ongoing blood loss. Hemoglobin and
hematocrit initially may be normal or decreased; BUN may
rise due to absorption of blood from the GI tract. Cool,
clammy skin indicates shock.
6. A client who had a Billroth I procedure
(gastroduodenostomy) reports dizziness, diaphoresis, and
diarrhea 20 minutes after eating. The nurse suspects:
A) Dumping syndrome
B) Afferent loop syndrome
C) Marginal ulcer
D) Gastric outlet obstruction
Answer: A. Dumping syndrome
Explanation: Dumping syndrome occurs after gastric surgery
when hypertonic chyme rapidly enters the small intestine,
causing fluid shift, vasomotor symptoms (dizziness,
diaphoresis, palpitations), and diarrhea. It is treated with
small, frequent low-carbohydrate meals.
7. A client with a nasogastric (NG) tube after gastric surgery
has absent bowel sounds and abdominal distention. The
nurse should:
A) Advance the NG tube
B) Notify the provider – possible paralytic ileus
C) Irrigate the tube with 30 mL of normal saline
D) Apply heat to the abdomen
