NUR2063 Exam 3: Essentials of Pathophysiology Comprehensive
Questions and Correct Answers with Explanation | Latest Update |
Rasmussen University
1. A patient with chronic gastroesophageal reflux disease (GERD) is diagnosed
with Barrett’s esophagus. What does this condition involve?
A. Hypertrophy of the esophageal muscle
B. Erosion of the mucosal layer only
C. Development of esophageal varices
D. Metaplasia of the esophageal squamous epithelium to columnar epithelium
Answer: D
Explanation: Barrett’s esophagus is a condition where the normal squamous epithelium of
the esophagus is replaced by columnar epithelium (metaplasia) due to chronic acid
exposure, increasing the risk of esophageal cancer.
2. Which organism is most commonly associated with the development of
peptic ulcer disease (PUD)?
A. Escherichia coli
B. Staphylococcus aureus
C. Helicobacter pylori
D. Streptococcus pyogenes
Answer: C
,Explanation: Helicobacter pylori is the primary cause of the majority of peptic ulcers by
weakening the protective mucous lining of the stomach and duodenum.
3. In patients with liver cirrhosis, what is the primary cause of hepatic
encephalopathy?
A. Increased serum bilirubin levels
B. Accumulation of ammonia in the blood
C. Excessive production of albumin
D. Low blood glucose levels
Answer: B
Explanation: Hepatic encephalopathy occurs when the failing liver cannot detoxify
nitrogenous waste products like ammonia, which then crosses the blood-brain barrier and
causes cognitive impairment.
4. Which type of hepatitis is primarily transmitted through the fecal-oral route?
A. Hepatitis A
B. Hepatitis B
C. Hepatitis C
D. Hepatitis D
Answer: A
Explanation: Hepatitis A and E are generally transmitted via the fecal-oral route, often
through contaminated food or water, unlike B, C, and D which are blood-borne.
,5. A patient presents with severe epigastric pain radiating to the back and
elevated serum lipase. What is the most likely diagnosis?
A. Cholecystitis
B. Appendicitis
C. Acute pancreatitis
D. Diverticulitis
Answer: C
Explanation: Acute pancreatitis is characterized by severe epigastric pain radiating to the
back and significant elevations in amylase and lipase enzymes.
6. Which characteristic is more typical of Crohn’s disease than Ulcerative Colitis?
A. Inflammation limited to the mucosal layer
B. Continuous lesions starting from the rectum
C. Skip lesions and transmural inflammation
D. Frequent bloody diarrhea
Answer: C
Explanation: Crohn’s disease is characterized by ‘skip lesions’ (affected areas separated by
healthy tissue) and inflammation that affects the entire thickness of the intestinal wall
(transmural).
, 7. A patient complains of pain in the Right Lower Quadrant (RLQ) at McBurney’s
point with rebound tenderness. This is a classic sign of:
A. Cholecystitis
B. Appendicitis
C. Pancreatitis
D. Renal calculi
Answer: B
Explanation: Appendicitis typically manifests as pain starting periumbilically and
migrating to McBurney’s point in the RLQ, often accompanied by rebound tenderness.
8. What is the primary pathophysiology of Portal Hypertension?
A. Low systemic blood pressure
B. Obstruction of blood flow through the liver
C. Increased urine output
D. Decreased heart rate
Answer: B
Explanation: Portal hypertension is caused by resistance to or obstruction of blood flow
through the liver, often due to cirrhosis, leading to increased pressure in the portal vein
system.
