1. A nurse is assessing a patient with uncomplicated GERD. What objective finding is
typically expected during the physical examination?
A. Epigastric tenderness
B. Normal physical examination
C. Esophageal stricture

2. A nurse is teaching about the pathophysiology of GERD. Which mechanisms
contribute to GERD? (Select all that apply.)
A. Lower esophageal sphincter (LES) dysfunction
B. Hiatal hernia
C. Esophageal motility disorders
D. Increased gastric acid production only
E. Impaired esophageal peristalsis
Correct Answer: A, B, C, E
Rationale: GERD is caused by LES dysfunction, hiatal hernia, and esophageal motility
disorders (impaired peristalsis), leading to gastric acid reflux into the esophagus.
3. A 52-year-old patient reports heartburn, regurgitation, and difficulty swallowing.
Which warning signs require further evaluation? (Select all that apply.)
A. Heartburn after meals
B. Dysphagia
C. Odynophagia
D. Weight loss
E. Melena
Correct Answer: B, C, D, E
Rationale: Warning signs in patients over 50 with GERD include dysphagia (difficulty

swallowing), odynophagia (painful swallowing), nausea/vomiting, weight loss, melena
(blood in stool), and early satiety.
4. A nurse is teaching about the pathophysiology of appendicitis. What is the initial
event that leads to appendicitis?
A. Bacterial infection of the appendix
B. Obstruction of the lumen of the appendix
C. Ischemia of the appendiceal wall
D. Perforation of the appendix
Correct Answer: B
Rationale: Appendicitis begins with obstruction of the lumen (often by a fecalith),
leading to inflammation, increased pressure, compromised blood flow, and potential
perforation.
5. A patient presents with periumbilical pain that later localizes to the right lower
quadrant. The nurse suspects which condition?
A. Gastroenteritis
B. Cholecystitis
C. Appendicitis
D. Pancreatitis
Correct Answer: C
