Advanced Gastrointestinal System
Assessment and Clinical Reasoning Multiple
Choice Questions (MCQs) with Answers and
Explanations for Nursing Degree and Clinical
Reasoning Exams
1. A nurse is assessing Peggy Scott, a 48-year-old patient presenting with epigastric
discomfort, early satiety, and intermittent nausea. Which finding would most strongly
indicate delayed gastric emptying rather than gastroesophageal reflux disease?
A. Retrosternal burning after meals
B. Sour taste in the mouth
C. Persistent postprandial fullness accompanied by vomiting several hours after eating
D. Pain relieved by antacids
Explanation: Delayed gastric emptying (gastroparesis) is characterized by prolonged retention
of gastric contents, resulting in fullness, nausea, and vomiting several hours after meals. GERD
typically presents with heartburn and regurgitation.
2. During abdominal assessment, the nurse notes absent bowel sounds in all four quadrants
after auscultating for five minutes. What is the most appropriate interpretation?
A. Normal age-related finding
B. Hyperactive intestinal motility
C. Acute gastroenteritis
D. Possible paralytic ileus requiring urgent evaluation
Explanation: Absence of bowel sounds after prolonged auscultation suggests paralytic ileus or
severe bowel dysfunction and warrants prompt assessment and intervention.
3. Peggy reports black, tarry stools for two days. Which pathophysiological process most
likely explains this finding?
A. Lower gastrointestinal bleeding
, B. Biliary obstruction
C. Upper gastrointestinal bleeding with digestion of blood in the intestine
D. Lactose intolerance
Explanation: Melena results from upper gastrointestinal bleeding, where blood is exposed to
digestive enzymes, producing characteristic black, tarry stools.
4. Which assessment finding would most strongly support a diagnosis of acute pancreatitis?
A. Right lower quadrant tenderness
B. Severe epigastric pain radiating to the back with elevated serum lipase
C. Left lower quadrant cramping relieved by defecation
D. Burning substernal pain after meals
Explanation: Acute pancreatitis commonly presents with severe epigastric pain radiating to the
back and elevated pancreatic enzymes, particularly lipase.
5. A nurse palpates a rigid abdomen with rebound tenderness in Peggy Scott. Which
condition should be suspected first?
A. Irritable bowel syndrome
B. Chronic constipation
C. Gastroesophageal reflux disease
D. Peritonitis
Explanation: Abdominal rigidity and rebound tenderness are classic signs of peritoneal
irritation and indicate a potentially life-threatening condition.
6. Which laboratory value would be most useful in evaluating hepatocellular injury?
A. Serum amylase
B. Blood urea nitrogen
C. Alanine aminotransferase (ALT)
D. Serum calcium
