1. A patient with a history of chronic hypertension presents with left
ventricular hypertrophy. Which cellular adaptation is primarily
responsible for this finding?
A) Hyperplasia
B) Atrophy
C) Hypertrophy
D) Metaplasia
Answer: C) Hypertrophy. Hypertrophy is an increase in cell size, leading
to organ enlargement. In chronic hypertension, the left ventricle pumps
against increased afterload, causing cardiac muscle cells to enlarge.
2. A shift in cell pH due to prolonged ischemia leads to which of the
following earliest cellular changes?
A) Nuclear fragmentation
B) Sodium and water accumulation in the cell
,2|Page
C) Lysosomal membrane rupture
D) Mitochondrial calcification
Answer: B) Sodium and water accumulation in the cell. Decreased ATP
production during ischemia disables the Na+/K+ pump, leading to
intracellular sodium accumulation. Water follows the osmotic gradient,
causing cellular swelling, a hallmark of reversible cell injury.
3. A pathologist examines a tissue sample and notes an area of brain
tissue that has been replaced by a cavity filled with debris and
surrounded by glial cells. This describes what type of necrosis?
A) Coagulative
B) Caseous
C) Liquefactive
D) Fat
Answer: C) Liquefactive. Liquefactive necrosis occurs when hydrolytic
enzymes digest dead cells into a viscous liquid, commonly seen in brain
infarcts and abscesses. The formation of a cystic space is characteristic.
4. Which cellular process demonstrates the replacement of one mature,
differentiated cell type with another mature cell type due to chronic
irritation?
A) Dysplasia
B) Metaplasia
C) Anaplasia
D) Neoplasia
,3|Page
Answer: B) Metaplasia. Metaplasia is a reversible adaptive change
where one adult cell type is replaced by another that is better able to
withstand stress, such as the change from pseudostratified columnar
epithelium to stratified squamous epithelium in the bronchi of smokers.
5. A patient's laboratory results show hyperuricemia. This substance is a
byproduct of the degradation of which molecules?
A) Carbohydrates
B) Purines
C) Pyrimidines
D) Amino acids
Answer: B) Purines. Uric acid is the end product of purine catabolism
(adenine and guanine). Elevated levels can lead to gout due to
monosodium urate crystal deposition in joints.
6. A complete arterial thrombus in a lower extremity leads to dry, black,
shrunken tissue. This morphological description is classic for what type
of gangrene?
A) Wet gangrene
B) Gas gangrene
C) Dry gangrene
D) Necrotizing fasciitis
Answer: C) Dry gangrene. Dry gangrene is a form of coagulative
necrosis resulting from chronic arterial occlusion. The tissue becomes
, 4|Page
dehydrated, shrinks, and turns black due to hemoglobin breakdown.
The line of demarcation is typically clear.
7. A patient presents with bilateral leg edema, ascites, and jugular
venous distention. These clinical findings are most suggestive of which
condition?
A) Left-sided heart failure
B) Right-sided heart failure
C) Deep vein thrombosis
D) Cirrhosis
Answer: B) Right-sided heart failure. Right ventricular failure impairs
the heart's ability to pump venous blood into the pulmonary
circulation, causing congestion in the systemic veins, leading to
peripheral edema, ascites, and increased JVP.
8. Which lab value is the most specific indicator of myocardial muscle
damage in the setting of an acute myocardial infarction?
A) Myoglobin
B) Creatine kinase-MB (CK-MB)
C) Troponin I
D) Lactate dehydrogenase (LDH)
Answer: C) Troponin I. Cardiac troponins (I and T) are highly specific
regulatory proteins released from damaged myocardium. They are the
gold standard biomarker for the diagnosis of acute MI due to their high
specificity and long half-life in serum.
