SECTION 1: CELLULAR PATHOPHYSIOLOGY & GENETICS (10 Questions)
Q1: A patient with heart failure presents with jugular vein distention, hepatomegaly,
and peripheral edema. What type of heart failure is this consistent with?
A. Left-sided heart failure
B. Right-sided heart failure
C. High-output heart failure
D. Cardiogenic shock
Correct Answer: B
Rationale: Correct because right-sided heart failure causes systemic venous
congestion and peripheral edema.
Q2: Which of the following is a hallmark of cellular adaptation to increased
workload?
A. Atrophy
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B
Rationale: Correct because hypertrophy is an increase in cell size in response to
increased demand.
Q3: A patient with pneumonia has crackles, fever, and productive cough. What is the
underlying pathophysiological process?
A. Inflammation and fluid accumulation in alveoli
B. Bronchospasm
C. Pulmonary embolus
D. Atelectasis
Correct Answer: A
Rationale: Correct because pneumonia involves inflammatory exudate in the alveoli.
,Q4: A patient with chronic kidney disease has elevated serum creatinine and BUN.
This indicates:
A. Decreased renal function
B. Increased renal function
C. Normal renal function
D. Hepatic dysfunction
Correct Answer: A
Rationale: Correct because elevated creatinine and BUN indicate decreased
glomerular filtration.
Q5: A patient with type 1 diabetes mellitus presents with fruity breath odor, Kussmaul
respirations, and blood glucose of 480 mg/dL. What is the most likely diagnosis?
A. Hypoglycemia
B. Diabetic ketoacidosis
C. Hyperosmolar hyperglycemic state
D. Lactic acidosis
Correct Answer: B
Rationale: Correct because fruity breath and Kussmaul respirations are hallmarks of
DKA.
Q6: A patient with a stroke has right-sided weakness and visual field deficit. Which
area of the brain is most likely affected?
A. Left hemisphere
B. Right hemisphere
C. Brainstem
D. Cerebellum
Correct Answer: A
Rationale: Correct because left hemisphere lesions cause right-sided weakness.
Q7: Which of the following is a characteristic of inflammation?
A. Vasoconstriction
B. Vasodilation and increased vascular permeability
C. Decreased blood flow
D. Decreased white blood cell count
Correct Answer: B
Rationale: Correct because inflammation involves vasodilation and increased
vascular permeability.
Q8: A patient with liver cirrhosis develops ascites. What is the underlying
pathophysiological mechanism?
, A. Decreased portal pressure
B. Portal hypertension and hypoalbuminemia
C. Increased aldosterone production
D. Decreased bilirubin production
Correct Answer: B
Rationale: Correct because portal hypertension and low albumin lead to fluid leakage
into the peritoneal cavity.
Q9: A patient with hyperkalemia and renal failure is at risk for which cardiac
complication?
A. Bradycardia
B. Cardiac arrhythmias
C. Hypotension
D. Heart block
Correct Answer: B
Rationale: Correct because hyperkalemia causes cardiac arrhythmias.
Q10: Which of the following is a sign of increased intracranial pressure?
A. Hypotension
B. Tachycardia
C. Cushing's triad (hypertension, bradycardia, irregular respirations)
D. Tachypnea
Correct Answer: C
Rationale: Correct because Cushing's triad indicates increased ICP.
SECTION 2: INFLAMMATION, IMMUNITY & INFECTION (10 Questions)
Q11: A patient with chronic obstructive pulmonary disease (COPD) has an FEV1/FVC
ratio of 58%. What does this indicate?
A. Restrictive lung disease
B. Obstructive lung disease
C. Normal lung function
D. Mixed lung disease
Correct Answer: B
Rationale: Correct because FEV1/FVC <70% indicates obstructive lung disease.
Q12: A patient with peptic ulcer disease is at risk for which complication?
A. Hemorrhage
B. Perforation
C. Gastric outlet obstruction
