This comprehensive exam assesses nursing competence in gastrointestinal care through 200 multiple-choice and scenario-based questions. The
purpose is to evaluate your ability to apply foundational theory, clinical judgment, and evidence-based practice to real-world patient situations.
Skills assessed include GI assessment techniques, diagnostic interpretation, postoperative care, ostomy management, medication administration,
patient education, and critical decision-making during GI emergencies. The exam emphasizes real-world application, regulatory compliance,
ethical standards, and professional nursing judgment essential for safe and effective GI nursing practice.

SECTION ONE: QUESTIONS 1–100
Question 1
A patient with gastroesophageal reflux disease (GERD) reports frequent heartburn after meals. Which nursing intervention should be prioritized?
A. Administer an antacid immediately
B. Elevate the head of the bed 6–8 inches
C. Encourage the patient to lie down after eating
D. Increase meal portion sizes
🟢 B. Elevate the head of the bed 6–8 inches
,🔴 RATIONALE: Elevating the head of the bed uses gravity to prevent gastric acid reflux, reducing heartburn. Antacids provide temporary relief but
do not prevent reflux. Lying down after eating worsens GERD, and larger meals increase gastric pressure.
Question 2
Which assessment finding in a patient with cirrhosis requires immediate nursing intervention?
A. Spider angiomas on the chest
B. Ascites with 2 kg weight gain in 24 hours
C. Palmar erythema
D. Mild pruritus
🟢 B. Ascites with 2 kg weight gain in 24 hours
🔴 RATIONALE: Rapid weight gain and worsening ascites indicate fluid overload and possible hepatic decompensation or spontaneous bacterial
peritonitis. Spider angiomas, palmar erythema, and pruritus are common chronic findings in cirrhosis but less urgent.
Question 3
A patient post-gastrectomy reports dizziness, sweating, and palpitations 30 minutes after eating. What is the most likely complication?
A. Hypoglycemia
B. Dumping syndrome
C. Vitamin B12 deficiency
D. Pernicious anemia
🟢 B. Dumping syndrome
🔴 RATIONALE: Dumping syndrome occurs when food rapidly enters the small intestine after gastrectomy, causing vasomotor symptoms like
dizziness, sweating, and palpitations within 30 minutes. Hypoglycemia occurs later (1–3 hours post-meal).
Question 4
Which laboratory value is most indicative of acute pancreatitis?
,A. Elevated serum sodium
B. Elevated serum amylase and lipase
C. Decreased bilirubin
D. Elevated hemoglobin
🟢 B. Elevated serum amylase and lipase
🔴 RATIONALE: Serum amylase and lipase levels rise 2–12 hours after pancreatitis onset and are diagnostic. Sodium, bilirubin, and hemoglobin are
not specific markers for acute pancreatitis.
Question 5
A patient with Crohn's disease is experiencing frequent diarrhea. Which dietary modification is most appropriate?
A. High-fiber diet
B. Low-residue diet
C. High-fat diet
D. Increased dairy intake
🟢 B. Low-residue diet
🔴 RATIONALE: A low-residue diet reduces stool frequency and bowel irritation in Crohn's disease. High-fiber and high-fat diets worsen diarrhea.
Dairy may exacerbate symptoms if lactose intolerance is present.
Question 6
Which nursing action is priority for a patient with a nasogastric (NG) tube on low intermittent suction?
A. Irrigate the tube with tap water every 4 hours
B. Monitor electrolyte levels regularly
C. Advance the tube 2 inches daily
D. Encourage oral fluids
🟢 B. Monitor electrolyte levels regularly
🔴 RATIONALE: NG suction can cause electrolyte imbalances (hypokalemia, hyponatremia). Tap water irrigation is not recommended (use normal
saline). Tubes are not advanced daily, and oral fluids may be contraindicated.
, Question 7
A patient with ulcerative colitis is started on sulfasalazine. Which teaching point is essential?
A. Take the medication on an empty stomach
B. Report signs of rash or sore throat immediately
C. Avoid sunlight exposure completely
D. Increase vitamin K intake
🟢 B. Report signs of rash or sore throat immediately
🔴 RATIONALE: Sulfasalazine can cause bone marrow suppression and hypersensitivity reactions. Rash or sore throat may indicate agranulocytosis.
The medication is taken with food to reduce GI upset.
Question 8
Which finding indicates successful management of hepatic encephalopathy?
A. Increased ammonia level
B. Improved level of consciousness
C. Worsening asterixis
D. Increased jaundice
🟢 B. Improved level of consciousness
🔴 RATIONALE: Improved consciousness indicates reduced ammonia levels and effective treatment. Increased ammonia, worsening asterixis, and
increased jaundice indicate deterioration.
Question 9
A patient with a colostomy expresses concern about odor. Which instruction is most appropriate?
A. Avoid all vegetables
B. Use deodorizing tablets in the pouch
C. Change the pouch daily regardless of output
D. Apply perfume to the pouch
🟢 B. Use deodorizing tablets in the pouch
