EXAM INSTRUCTIONS
Recommended time: 3 hours
Questions: 200
Format: Multiple choice
Directions: Select the single best answer.
For maximum simulation value:
• Do not consult the rationales until you finish.
• Treat each question as requiring application rather than simple recall.
• Pay particular attention to mechanism, not merely diagnosis.
• When two answers seem plausible, determine which one most directly
explains the findings in the vignette.
PART I — CELLULAR PATHOPHYSIOLOGY & HOMEOSTASIS
1.
A 72-year-old patient is admitted with severe dehydration after three days of vomiting and
diarrhea. Laboratory testing demonstrates elevated serum sodium and increased serum
osmolality. Which cellular response is most likely occurring?
A. Water moves into cells, causing cellular swelling
B. Water moves out of cells, causing cellular shrinkage
C. Sodium rapidly leaves the extracellular compartment
D. Intracellular fluid becomes hypotonic relative to plasma
2.
A patient experiences an acute coronary artery occlusion. Within minutes, myocardial cells begin
relying increasingly on anaerobic metabolism. Which change occurs first as ATP production
declines?
,A. Increased oxidative phosphorylation
B. Failure of ATP-dependent membrane ion pumps
C. Increased intracellular protein synthesis
D. Increased aerobic metabolism
3.
A patient suffers prolonged cerebral ischemia. Unlike an infarction of the myocardium, the
damaged brain tissue undergoes liquefactive necrosis. Which mechanism best explains this
difference?
A. Brain tissue contains no lysosomes
B. Enzymatic digestion dominates the response in CNS tissue
C. Cerebral neurons cannot undergo necrosis
D. Brain tissue undergoes coagulative necrosis followed by calcification
4.
A patient has chronic gastroesophageal reflux and develops replacement of normal esophageal
squamous epithelium with a columnar epithelial phenotype. Which cellular adaptation has
occurred?
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
5.
A patient with long-standing hypertension develops thickening of the left ventricular wall. Which
statement best explains this adaptation?
A. Increased afterload increases myocardial workload
B. Reduced workload stimulates myocardial enlargement
C. Increased preload always causes cellular death
D. Hypertension directly causes myocardial hyperplasia
6.
, A patient is found unconscious after an opioid overdose. Respiratory rate is markedly decreased
and PaCO₂ is elevated. Which acid-base disturbance is most likely?
A. Respiratory alkalosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Metabolic acidosis
7.
A patient with prolonged diarrhea has a bicarbonate level of 16 mEq/L and a low arterial pH.
Which primary disorder is most likely?
A. Respiratory acidosis
B. Metabolic acidosis
C. Respiratory alkalosis
D. Metabolic alkalosis
8.
A patient develops severe hypoxia. Cellular ATP production declines and the sodium-potassium
pump becomes ineffective. Which immediate intracellular consequence is expected?
A. Potassium enters the cell and sodium leaves
B. Sodium accumulates intracellularly and water follows
C. Calcium is completely removed from the cell
D. Intracellular water decreases
9.
A patient with severe burns develops extensive tissue damage. Which finding most strongly
indicates irreversible cellular injury?
A. Mild cellular swelling
B. Fatty change
C. Severe membrane disruption and inability to restore mitochondrial function
D. Temporary reduction in ATP production
10.
