ABSTRACT
This study document brings together 50 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
molecular and cellular mechanisms of disease and their systemic manifestations, Apply
pathophysiologic principles to interpret clinical data and predict outcomes and Synthesize
knowledge across organ systems to explain complex disease presentations. 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 MOLECULAR AND CELLULAR MECHANISMS OF DISEASE AND THEIR
SYSTEMIC MANIFESTATIONS
A patient with chronic kidney disease has an arterial blood gas showing pH 7.32,
PaCO2 30 mmHg, and HCO3- 15 mEq/L. What is the primary acid-base disorder?
A. Metabolic acidosis with respiratory compensation CORRECT
B. Respiratory alkalosis with metabolic compensation
C. Mixed metabolic acidosis and respiratory alkalosis
D. Metabolic alkalosis with respiratory compensation
RATIONALE: The low pH indicates acidosis; the low HCO3- suggests a metabolic origin. The low
PaCO2 reflects respiratory compensation (hyperventilation), consistent with Winter's formula.
Without compensation, PaCO2 would be higher, so this is not a mixed disorder.
Q2 ANALYZE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE AND THEIR
SYSTEMIC MANIFESTATIONS
Which molecular defect best explains the premature atherosclerosis seen in
familial hypercholesterolemia?
A. Defective LDL receptor leading to reduced hepatic clearance of LDL CORRECT
B. Overproduction of apolipoprotein B-100
C. Increased lipoprotein lipase activity
D. Deficiency of cholesteryl ester transfer protein
RATIONALE: Familial hypercholesterolemia is most commonly caused by mutations in the LDLR
gene, impairing receptor-mediated endocytosis of LDL and causing markedly elevated LDL-C.
Overproduction of apoB-100 occurs in familial combined hyperlipidemia, while increased LPL
activity would lower triglycerides. CETP deficiency leads to high HDL, not premature
atherosclerosis.

, Q3 ANALYZE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE AND THEIR
SYSTEMIC MANIFESTATIONS
In a patient with septic shock, which pathophysiologic mechanism primarily
accounts for the hypotension refractory to fluid resuscitation?
A. Inducible nitric oxide synthase-mediated vasodilation CORRECT
B. Increased systemic vascular resistance
C. Cardiogenic depression due to myocardial infarction
D. Hypovolemia from third-spacing
RATIONALE: Septic shock involves endotoxin-induced upregulation of iNOS, producing
excessive nitric oxide that causes profound vasodilation and vasopressor-resistant hypotension.
Increased SVR is opposite to the vasodilation seen. Cardiogenic and hypovolemic components
may coexist but are not the primary mechanism of refractory hypotension.
Q4 ANALYZE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE AND THEIR
SYSTEMIC MANIFESTATIONS
Which statement best describes the role of tumor suppressor gene inactivation in
the two-hit hypothesis of retinoblastoma?
A. Both alleles of RB1 must be inactivated for tumor formation. CORRECT
B. A single hit in RB1 is sufficient for tumorigenesis.
C. RB1 inactivation leads to increased apoptosis.
D. RB1 mutations are always inherited.
RATIONALE: Knudson's two-hit hypothesis states that both alleles of a tumor suppressor gene
like RB1 must be inactivated (e.g., mutation plus loss of heterozygosity) for cancer to develop. A
single hit is insufficient because the remaining wild-type allele can still function. RB1 mutations
can be sporadic or inherited, and loss of RB1 leads to uncontrolled cell cycle progression, not
increased apoptosis.
