QUESTION 1
A 55-year-old male is admitted with severe sepsis. Which of the following
pathophysiologic mechanisms is most responsible for the hypotension observed in
septic shock?
• A. Decreased cardiac contractility
• B. Widespread vasodilation and increased capillary permeability
• C. Increased systemic vascular resistance
• D. Decreased heart rate
Correct Answer: B
Rationale: Septic shock is characterized by widespread vasodilation due to inflammatory
mediator release (e.g., nitric oxide, cytokines) and increased capillary permeability, leading
to relative hypovolemia and hypotension. Decreased cardiac contractility (A) can occur in
late stages but vasodilation is the primary mechanism.
,QUESTION 2
A 42-year-old female with a history of recurrent angioedema and abdominal pain is
found to have a deficiency of C1 esterase inhibitor. This condition is classified as:
• A. Acquired angioedema
• B. Hereditary angioedema
• C. Anaphylaxis
• D. Serum sickness
Correct Answer: B
Rationale: Hereditary angioedema is caused by a deficiency or dysfunction of C1 esterase
inhibitor, leading to uncontrolled activation of the complement system and bradykinin-
mediated angioedema. Acquired angioedema (A) is associated with lymphoproliferative
disorders or autoimmune diseases.
QUESTION 3
A 60-year-old male with a history of alcohol abuse presents with confusion, ataxia, and
ophthalmoplegia. The most likely diagnosis is:
• A. Wernicke's encephalopathy
• B. Korsakoff's syndrome
• C. Hepatic encephalopathy
• D. Delirium tremens
Correct Answer: A
Rationale: Wernicke's encephalopathy is caused by thiamine (vitamin B1) deficiency,
commonly seen in alcohol use disorder. It is characterized by the triad of confusion, ataxia,
and ophthalmoplegia. Korsakoff's syndrome (B) is a chronic memory disorder that may
follow Wernicke's.
,QUESTION 4
A 35-year-old male with a history of Crohn's disease has a fistula between the ileum and
the bladder. This complication is most directly related to which pathophysiologic feature
of Crohn's disease?
• A. Mucosal inflammation
• B. Transmural inflammation
• C. Skip lesions
• D. Granuloma formation
Correct Answer: B
Rationale: Crohn's disease is characterized by transmural inflammation that extends
through all layers of the bowel wall, leading to fistula formation. Ulcerative colitis (A)
involves only mucosal inflammation.
QUESTION 5
A 70-year-old female with heart failure has an ejection fraction of 55%. Which type of
heart failure is most likely?
• A. Heart failure with reduced ejection fraction (HFrEF)
• B. Heart failure with preserved ejection fraction (HFpEF)
• C. High-output heart failure
• D. Right-sided heart failure
Correct Answer: B
Rationale: HFpEF (diastolic dysfunction) is characterized by an ejection fraction ≥ 50%
with impaired ventricular relaxation and filling. HFrEF (A) has an ejection fraction < 40%.
, QUESTION 6
A 28-year-old female with a history of recurrent kidney stones is found to have a
mutation in the SLC3A1 gene. This mutation is associated with:
• A. Cystinuria
• B. Hyperoxaluria
• C. Hyperuricemia
• D. Hypercalciuria
Correct Answer: A
Rationale: SLC3A1 gene mutations cause cystinuria, a disorder of renal tubular amino acid
transport leading to cystine stone formation. Hyperoxaluria (B) is associated with other
genetic mutations.
QUESTION 7
A 65-year-old male with a history of COPD has a PaCO₂ of 60 mm Hg and a pH of 7.35.
This finding indicates:
• A. Acute respiratory acidosis
• B. Chronic respiratory acidosis with compensation
• C. Metabolic alkalosis
• D. Normal acid-base balance
Correct Answer: B
Rationale: A PaCO₂ of 60 mm Hg indicates respiratory acidosis. A pH of 7.35 (near
normal) indicates renal compensation (increased HCO₃⁻), suggesting chronic respiratory
acidosis.
