ABSTRACT
This study document brings together 100 carefully worded exam questions drawn from SUNY
Downstate Medical Center NRMS 5190 Advanced Pathophysiology Final Exam Questions and
Correct Answers plus Rationale New Update, with the strongest emphasis placed on Analyze
cellular and molecular mechanisms of disease and their clinical manifestations, Integrate
pathophysiologic concepts across organ systems to interpret complex clinical data and Apply
evidence-based guidelines and recent research to diagnose and manage pathophysiologic states.
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 ANALYZE CELLULAR AND MOLECULAR MECHANISMS OF DISEASE AND THEIR
CLINICAL MANIFESTATIONS
In a patient with septic shock, which combination of hemodynamic and metabolic
findings best distinguishes maldistributive from cardiogenic shock at the cellular
level?
A. Increased mixed venous oxygen saturation and decreased arteriovenous oxygen difference
CORRECT
B. Decreased mixed venous oxygen saturation and increased arteriovenous oxygen difference
C. Increased systemic vascular resistance and decreased cardiac output
D. Decreased lactate with increased central venous pressure
RATIONALE: Septic shock causes impaired oxygen extraction due to microcirculatory shunting
and mitochondrial dysfunction, leading to elevated SvO2 and narrowed a-vO2 difference.
Cardiogenic shock typically shows widened a-vO2 difference from increased extraction. Options
B and C describe cardiogenic or hypovolemic patterns, and D is nonspecific.
Q2 ANALYZE CELLULAR AND MOLECULAR MECHANISMS OF DISEASE AND THEIR
CLINICAL MANIFESTATIONS
Which molecular alteration is most directly responsible for the constitutive
activation of the JAK-STAT pathway in myeloproliferative neoplasms?
A. BCR-ABL1 fusion
B. JAK2 V617F mutation CORRECT
C. FLT3 internal tandem duplication
D. PML-RARA translocation
RATIONALE: The JAK2 V617F mutation in the pseudokinase domain leads to constitutive kinase
activity and cytokine-independent growth in polycythemia vera, essential thrombocythemia, and
primary myelofibrosis. BCR-ABL1 defines CML, FLT3-ITD is in AML, and PML-RARA is in acute
promyelocytic leukemia.

,Q3 ANALYZE CELLULAR AND MOLECULAR MECHANISMS OF DISEASE AND THEIR
CLINICAL MANIFESTATIONS
In a patient with acute respiratory distress syndrome (ARDS), which
pathophysiologic mechanism primarily accounts for the characteristic bilateral
opacities and refractory hypoxemia?
A. Increased pulmonary capillary hydrostatic pressure
B. Decreased alveolar surface tension due to surfactant excess
C. Increased alveolar-capillary membrane permeability with protein-rich edema CORRECT
D. Bronchial smooth muscle constriction and mucus plugging
RATIONALE: ARDS is defined by increased permeability of the alveolar-capillary barrier, leading
to high-protein pulmonary edema, surfactant dysfunction, and intrapulmonary shunting.
Cardiogenic pulmonary edema (A) has low-protein fluid, surfactant excess (B) is not typical, and
D describes asthma.
Q4 ANALYZE CELLULAR AND MOLECULAR MECHANISMS OF DISEASE AND THEIR
CLINICAL MANIFESTATIONS
A patient with chronic kidney disease develops anemia. Which pathophysiologic
mechanism is the primary driver?
A. Iron deficiency due to chronic blood loss
B. Decreased erythropoietin production by peritubular fibroblasts CORRECT
C. Autoimmune hemolysis
D. Vitamin B12 malabsorption
RATIONALE: CKD leads to loss of peritubular fibroblasts, reducing erythropoietin synthesis and
causing normocytic normochromic anemia. Iron deficiency (A) may coexist but is not primary;
hemolysis (C) and B12 deficiency (D) are unrelated to CKD pathophysiology.

, Q5 ANALYZE CELLULAR AND MOLECULAR MECHANISMS OF DISEASE AND THEIR
CLINICAL MANIFESTATIONS
Which statement best describes the role of tumor suppressor gene inactivation in
the two-hit hypothesis of retinoblastoma?
A. A single mutation in one allele is sufficient for tumor formation.
B. Both alleles must be inactivated for tumor development. CORRECT
C. Mutations in oncogenes are required in addition to RB1 loss.
D. Epigenetic silencing alone can cause retinoblastoma without genetic mutation.
RATIONALE: Knudson's two-hit hypothesis states that both alleles of a tumor suppressor gene
like RB1 must be inactivated for tumorigenesis. A is incorrect because one hit is insufficient; C is
not required; D is rare and not the primary mechanism.
Q6 ANALYZE CELLULAR AND MOLECULAR MECHANISMS OF DISEASE AND THEIR
CLINICAL MANIFESTATIONS
In heart failure with reduced ejection fraction, which compensatory mechanism
initially maintains cardiac output but ultimately contributes to disease
progression?
A. Increased parasympathetic tone
B. Activation of the renin-angiotensin-aldosterone system CORRECT
C. Upregulation of natriuretic peptides
D. Decreased sympathetic nervous system activity
RATIONALE: RAAS activation increases preload and afterload via sodium and water retention
and vasoconstriction, initially preserving perfusion but worsening remodeling and fibrosis.
Parasympathetic tone (A) is reduced, natriuretic peptides (C) are compensatory but not the
primary driver, and sympathetic activity (D) is increased, not decreased.
