ABSTRACT
This study document brings together 98 carefully worded exam questions drawn from SUNY
Downstate Medical Center NRMS 5190 Advanced Pathophysiology Exam and Answers plus
Rationale New Update 2026-2027 Graded A+, with the strongest emphasis placed on Differentiate
molecular and cellular mechanisms of disease across organ systems, Apply pathophysiologic
reasoning to interpret complex clinical and laboratory data and Critically evaluate current guidelines
and landmark studies in pathophysiology. 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 DIFFERENTIATE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE ACROSS
ORGAN SYSTEMS
A novel monoclonal antibody blocks the interaction between PD-1 and PD-L1. In a
patient with sepsis-induced immunoparalysis, which pathophysiologic
consequence is most likely?
A. Enhanced T-cell exhaustion and increased secondary infection risk.
B. Restoration of T-cell effector function and improved pathogen clearance. CORRECT
C. Increased regulatory T-cell suppression of innate immunity.
D. Upregulation of anti-inflammatory cytokines IL-10 and TGF-.
RATIONALE: PD-1/PD-L1 blockade reverses T-cell exhaustion, restoring effector function and
pathogen clearance in immunoparalysis. The other options describe immunosuppressive or
exhaustion-promoting effects, which are opposite to checkpoint inhibition.
Q2 DIFFERENTIATE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE ACROSS
ORGAN SYSTEMS
In a patient with heart failure with preserved ejection fraction (HFpEF), which
hemodynamic profile is most characteristic?
A. Reduced left ventricular end-diastolic volume and low filling pressures.
B. Increased left ventricular end-diastolic pressure and concentric hypertrophy. CORRECT
C. Dilated left ventricle with eccentric hypertrophy and reduced contractility.
D. Normal diastolic function with elevated cardiac output.
RATIONALE: HFpEF typically presents with concentric hypertrophy, impaired relaxation, and
elevated filling pressures despite normal ejection fraction. The other options describe HFrEF or
normal physiology.

,Q3 DIFFERENTIATE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE ACROSS
ORGAN SYSTEMS
Which molecular alteration best explains the constitutive activation of the
JAK-STAT pathway in myeloproliferative neoplasms?
A. BCR-ABL1 fusion gene.
B. JAK2 V617F mutation. CORRECT
C. FLT3 internal tandem duplication.
D. IDH1/2 mutation.
RATIONALE: JAK2 V617F is the most common driver mutation in myeloproliferative neoplasms,
leading to constitutive JAK-STAT signaling. BCR-ABL1 is seen in CML, FLT3-ITD in AML, and
IDH mutations in gliomas and AML.
Q4 DIFFERENTIATE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE ACROSS
ORGAN SYSTEMS
In acute respiratory distress syndrome (ARDS), which mechanism primarily
contributes to refractory hypoxemia?
A. Increased dead space ventilation.
B. Intrapulmonary shunt due to alveolar filling. CORRECT
C. Diffusion limitation from thickened alveolar membrane.
D. Hypoventilation from respiratory muscle fatigue.
RATIONALE: ARDS causes alveolar flooding and collapse, leading to intrapulmonary shunt that
is refractory to supplemental oxygen. Dead space, diffusion limitation, and hypoventilation
contribute but are not the primary cause of refractory hypoxemia.

, Q5 DIFFERENTIATE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE ACROSS
ORGAN SYSTEMS
A patient with chronic kidney disease has metabolic acidosis with a normal anion
gap. Which pathophysiologic process is most likely?
A. Lactic acidosis from tissue hypoperfusion.
B. Diabetic ketoacidosis.
C. Type 4 renal tubular acidosis. CORRECT
D. Salicylate toxicity.
RATIONALE: Type 4 RTA causes hyperkalemic normal anion gap acidosis due to aldosterone
deficiency or resistance. The other options cause high anion gap acidosis.
Q6 DIFFERENTIATE MOLECULAR AND CELLULAR MECHANISMS OF DISEASE ACROSS
ORGAN SYSTEMS
Which mechanism best explains the development of diabetic nephropathy in a
patient with long-standing type 2 diabetes?
A. Immune complex deposition in glomeruli.
B. Hyperglycemia-induced mesangial expansion and glomerular hyperfiltration. CORRECT
C. Amyloid deposition in renal tubules.
D. Direct bacterial infection of the renal pelvis.
RATIONALE: Diabetic nephropathy results from hyperglycemia-driven mesangial matrix
expansion, glomerular hypertrophy, and hyperfiltration, leading to proteinuria and renal failure.
The other options are not typical mechanisms.
