ABSTRACT
This study document brings together 48 carefully worded exam questions drawn from SUNY
Downstate Medical Center NRMS 5190 Advanced Pathophysiology Exam 2 (V2) Questions and
Answers plus Rationale New Update 2026-2027 Graded A+, with the strongest emphasis placed
on Explain the molecular and cellular mechanisms underlying disease processes across major
organ systems, Integrate genetic, environmental, and immunologic factors in the pathogenesis of
complex disorders and Apply pathophysiological principles to interpret clinical findings and
diagnostic data. Every item follows the wording style and level of reasoning you meet in the real
paper, and each one is paired with a clear rationale so the correct choice is never a guess. Work
through the set at your own pace, mark the questions that slow you down, then come back to them
until the reasoning feels automatic. Learners who revise this way walk into the exam room
recognising the pattern behind the questions instead of meeting them for the first time. Keep going
- steady, honest practice is what turns a difficult paper into a comfortable pass.

,Q1 EXPLAIN THE MOLECULAR AND CELLULAR MECHANISMS UNDERLYING DISEASE
PROCESSES ACROSS MAJOR ORGAN SYSTEMS
In the context of ischemia-reperfusion injury, which mechanism most directly
accounts for the paradoxical exacerbation of cellular damage upon restoration of
blood flow?
A. Activation of anaerobic glycolysis leading to lactic acidosis
B. Generation of reactive oxygen species by xanthine oxidase and mitochondrial electron
transport chain CORRECT
C. Depletion of ATP causing failure of Na+/K+-ATPase pumps
D. Increased intracellular calcium due to enhanced sarcolemmal permeability
RATIONALE: Reperfusion reintroduces oxygen, which drives ROS production via xanthine
oxidase and mitochondrial complexes, causing oxidative damage. Anaerobic glycolysis and ATP
depletion occur during ischemia, not reperfusion. Calcium overload is a consequence, not the
primary trigger of paradoxical injury.
Q2 EXPLAIN THE MOLECULAR AND CELLULAR MECHANISMS UNDERLYING DISEASE
PROCESSES ACROSS MAJOR ORGAN SYSTEMS
A patient with chronic granulomatous disease (CGD) is expected to have impaired
killing of which organisms due to defective NADPH oxidase?
A. Streptococcus pneumoniae and Neisseria meningitidis
B. Staphylococcus aureus and Aspergillus fumigatus CORRECT
C. Mycobacterium tuberculosis and Listeria monocytogenes
D. Candida albicans and Cryptococcus neoformans
RATIONALE: CGD patients have defective respiratory burst, impairing killing of catalase-positive
organisms like S. aureus and Aspergillus. Catalase-negative organisms produce H2O2, partially
compensating. T-cell mediated pathogens like Mycobacterium are less dependent on oxidative
burst.

, Q3 EXPLAIN THE MOLECULAR AND CELLULAR MECHANISMS UNDERLYING DISEASE
PROCESSES ACROSS MAJOR ORGAN SYSTEMS
Which molecular alteration best explains the constitutive activation of the
JAK2-STAT pathway in polycythemia vera?
A. BCR-ABL1 fusion gene
B. JAK2 V617F point mutation CORRECT
C. FLT3 internal tandem duplication
D. KIT D816V mutation
RATIONALE: The JAK2 V617F mutation leads to constitutive tyrosine kinase activity, driving
erythropoiesis independent of EPO. BCR-ABL1 is seen in CML, FLT3 in AML, and KIT D816V in
systemic mastocytosis.
Q4 EXPLAIN THE MOLECULAR AND CELLULAR MECHANISMS UNDERLYING DISEASE
PROCESSES ACROSS MAJOR ORGAN SYSTEMS
In the pathogenesis of systemic lupus erythematosus (SLE), which mechanism is
most directly responsible for the formation of immune complexes that deposit in
tissues?
A. Defective clearance of apoptotic cells leading to autoantigen exposure CORRECT
B. Overproduction of IL-2 by Th1 cells
C. Increased complement-mediated lysis of self-cells
D. Enhanced T-cell receptor signaling due to HLA-DR4
RATIONALE: Impaired clearance of apoptotic debris in SLE exposes nuclear antigens, driving
autoantibody production and immune complex formation. IL-2 overproduction is not central;
complement activation is a consequence, not cause. HLA association modulates risk but does
not directly form complexes.
