,Q1. A laboratory technician spills a chemical on their arm, causing immediate
epidermal necrosis with minimal pain. Which mechanism of cell injury is most likely
responsible?
A. Apoptosis via caspase activation
B. Coagulative necrosis from protein denaturation
C. Liquefactive necrosis from autolysis
D. Fat necrosis from lipase release
Correct Answer: B. Coagulative necrosis from protein denaturation
Rationale: Chemical injury denatures proteins and disrupts cellular enzymes, leading to
coagulative necrosis. Apoptosis is programmed and does not cause necrosis. Liquefactive
necrosis typically occurs in brain infections. Fat necrosis involves lipase release from fatty
tissues.
Why Wrong:
A - Apoptosis is a regulated process that does not cause necrosis or immediate tissue
damage from chemicals.
C - Liquefactive necrosis is characteristic of hydrolytic enzyme activity, as in
abscesses, not chemical denaturation.
D - Fat necrosis results from lipase-mediated fatty acid release, usually in pancreatic
injury or trauma to adipose tissue.

Q2. A patient with a recent Streptococcal pharyngitis develops acute
glomerulonephritis. Which hypersensitivity mechanism is primarily responsible?
A. Type I IgE-mediated mast cell degranulation
B. Type II antibody-mediated cytotoxicity
C. Type III immune complex deposition
D. Type IV T-cell mediated delayed hypersensitivity
Correct Answer: C. Type III immune complex deposition
Rationale: Post-streptococcal glomerulonephritis results from deposition of immune
complexes (antigen-antibody) in glomerular basement membranes, triggering complement
activation and inflammation. Type I involves IgE, type II targets specific cells, type IV is
T-cell mediated.
Why Wrong:
A - Type I hypersensitivity causes immediate allergic reactions like anaphylaxis, not
glomerular damage.
B - Type II reactions involve antibodies against cell surface antigens, as in
autoimmune hemolytic anemia.
D - Type IV hypersensitivity is mediated by T-cells, seen in contact dermatitis or

Q3. Which of the following best explains the protective role of p53 mutations in
cancer progression?
A. p53 mutations enhance DNA repair, reducing further mutations.
B. Loss of p53 function allows cells with damaged DNA to survive and proliferate.
C. Mutant p53 directly activates oncogenes, accelerating tumor growth.
D. p53 mutations promote apoptosis of premalignant cells.
Correct Answer: B. Loss of p53 function allows cells with damaged DNA to survive
and proliferate.
Rationale: p53 is a tumor suppressor that induces cell cycle arrest or apoptosis in
response to DNA damage. Loss-of-function mutations eliminate this checkpoint, permitting
survival of genetically unstable cells. Options A, C, and D are incorrect as p53 mutations
impair, not enhance, these processes.
Why Wrong:
A - p53 normally promotes DNA repair; mutations impair repair, increasing
mutagenesis.
C - Mutant p53 may gain oncogenic functions, but the primary protective role lost is
checkpoint control.
D - p53 induces apoptosis; loss of function reduces apoptosis of damaged cells.

Ed., Ch. 7
Q4. A patient with syndrome of inappropriate antidiuretic hormone (SIADH)
presents with severe hyponatremia. Which compensatory mechanism is most likely
contributing to cerebral edema?
A. Increased extracellular osmolarity pulling water into brain cells
B. Adaptive loss of intracellular solutes (idiogenic osmoles)
C. Failure of the blood-brain barrier to exclude sodium
D. Rapid water movement into neurons due to hypo-osmolality
Correct Answer: D. Rapid water movement into neurons due to hypo-osmolality
Rationale: Hyponatremia from SIADH causes extracellular hypo-osmolality, leading to
water influx into brain cells via osmosis, causing cerebral edema. Compensation includes
loss of idiogenic osmoles (option B) but that is protective, not contributory. Options A and
C are incorrect.
Why Wrong:
A - Extracellular osmolarity is low in hyponatremia, not high; water moves into cells.
