Essentials of Pathophysiology Q&A with
Rationale | Rasmussen University
1. A patient presents with hematemesis and a history of chronic alcoholism. The nurse
suspects esophageal varices. Which underlying condition is the primary cause of this life-
threatening complication?
A. Chronic gastric acid reflux
B. Helicobacter pylori infection
C. Decreased clotting factors
D. Portal hypertension
Correct Answer: D
Rationale: Portal hypertension occurs when blood flow through the liver is obstructed,
often due to cirrhosis. This increased pressure forces blood into smaller collateral vessels,
such as those in the esophagus, causing them to become fragile and prone to rupture.
Without intervention, these varices can lead to massive hemorrhage and death.
2. Which clinical manifestation is characteristic of Ulcerative Colitis but is less common in
Crohn’s disease?
A. Bloody diarrhea
B. Skip lesions
,C. Transmural inflammation
D. Fistula formation
Correct Answer: A
Rationale: Ulcerative Colitis primarily involves the mucosal layer of the colon and rectum,
leading to frequent bloody stools and mucus. In contrast, Crohn’s disease is characterized
by transmural inflammation and skip lesions throughout the GI tract. The superficial nature
of the ulcerations in UC is what drives the high frequency of rectal bleeding.
3. A patient is diagnosed with acute pancreatitis. Which laboratory values would the nurse
expect to be significantly elevated?
A. Amylase and Lipase
B. Bilirubin and Albumin
C. Sodium and Potassium
D. Hemoglobin and Hematocrit
Correct Answer: A
Rationale: Acute pancreatitis involves the autodigestion of the pancreas by its own
enzymes. Amylase and lipase are released into the bloodstream when pancreatic acinar
cells are damaged. Lipase is generally considered more specific to the pancreas and stays
elevated longer than amylase.
, 4. A patient with chronic kidney disease (CKD) has a low hemoglobin level. What is the
primary pathophysiological reason for this finding?
A. Iron deficiency due to poor diet
B. Chronic occult gastrointestinal bleeding
C. Shortened lifespan of red blood cells
D. Reduced production of erythropoietin
Correct Answer: D
Rationale: The kidneys are responsible for producing erythropoietin, a hormone that
stimulates red blood cell production in the bone marrow. As kidney function declines, the
production of this hormone decreases, leading to anemia. This condition is a hallmark of
advanced chronic kidney disease and often requires synthetic hormone replacement.
5. What is the most common cause of intrarenal acute kidney injury (AKI)?
A. Prostatic hypertrophy
B. Hypovolemia
C. Renal calculi
D. Acute tubular necrosis (ATN)
Correct Answer: D
Rationale: Acute tubular necrosis (ATN) is the most frequent cause of intrarenal AKI, often
resulting from ischemia or nephrotoxic agents. This involves direct damage to the renal
