EDAPT Weeks 4-8 Advanced Pathophysiology Exam 2026/2027 250 Verified Questions &
Answers Chamberlain University Prep 5 Core Domains Instant Download, with the strongest
emphasis placed on Differentiate the pathophysiologic mechanisms underlying cardiovascular,
pulmonary, renal, GI/hepatic, and endocrine disorders, Analyze laboratory, diagnostic, and
hemodynamic data to identify disease progression and complications and Evaluate the safety and
appropriateness of pharmacologic and non-pharmacologic interventions using pathophysiologic
rationale. 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 THE PATHOPHYSIOLOGIC MECHANISMS UNDERLYING
CARDIOVASCULAR, PULMONARY, RENAL, GI/HEPATIC, AND ENDOCRINE DISORDERS
A patient with chronic heart failure has a BNP of 1200 pg/mL and an
echocardiogram showing an ejection fraction of 35%. Which pathophysiologic
mechanism best explains the elevated BNP?
A. Increased ventricular preload causing atrial natriuretic peptide release
B. Ventricular myocyte stretch due to elevated filling pressures CORRECT
C. Renal hypoperfusion stimulating erythropoietin production
D. Systemic vasodilation reducing afterload and increasing BNP clearance
RATIONALE: BNP is released primarily from ventricular myocytes in response to wall stretch
from elevated filling pressures (preload) and volume overload. Atrial natriuretic peptide (ANP) is
mainly atrial, and erythropoietin is unrelated. Vasodilation would not directly increase BNP; it may
reduce stretch.

,Q2 DIFFERENTIATE THE PATHOPHYSIOLOGIC MECHANISMS UNDERLYING
CARDIOVASCULAR, PULMONARY, RENAL, GI/HEPATIC, AND ENDOCRINE DISORDERS
Which arterial blood gas pattern is most consistent with acute respiratory distress
syndrome (ARDS) in its early exudative phase?
A. pH 7.48, PaCO2 30, HCO3 22, PaO2 55 on room air CORRECT
B. pH 7.30, PaCO2 55, HCO3 26, PaO2 80 on room air
C. pH 7.38, PaCO2 40, HCO3 24, PaO2 90 on room air
D. pH 7.25, PaCO2 35, HCO3 15, PaO2 70 on room air
RATIONALE: Early ARDS causes refractory hypoxemia (PaO2 <60) and respiratory alkalosis
from hyperventilation (low PaCO2, elevated pH). Option B reflects hypoventilation, C is normal,
and D suggests metabolic acidosis with respiratory compensation, not typical early ARDS.
Q3 DIFFERENTIATE THE PATHOPHYSIOLOGIC MECHANISMS UNDERLYING
CARDIOVASCULAR, PULMONARY, RENAL, GI/HEPATIC, AND ENDOCRINE DISORDERS
A patient with diabetic nephropathy has a glomerular filtration rate of 45
mL/min/1.73 m² and proteinuria. Which pathophysiologic change is most directly
responsible for the proteinuria?
A. Increased glomerular capillary permeability due to podocyte injury CORRECT
B. Decreased tubular reabsorption of filtered proteins
C. Reduced renal plasma flow causing ischemic tubular damage
D. Elevated serum protein concentration overwhelming filtration
RATIONALE: Proteinuria in diabetic nephropathy results from damage to the glomerular filtration
barrier, particularly podocyte injury and loss of negative charge, increasing permeability to
proteins. Tubular reabsorption defects can cause low-molecular-weight proteinuria but are not the
primary mechanism here. Hyperproteinemia rarely causes proteinuria.

, Q4 DIFFERENTIATE THE PATHOPHYSIOLOGIC MECHANISMS UNDERLYING
CARDIOVASCULAR, PULMONARY, RENAL, GI/HEPATIC, AND ENDOCRINE DISORDERS
Which statement best describes the role of hepatic stellate cells in the progression
of cirrhosis?
A. They transform into myofibroblasts and produce excessive collagen CORRECT
B. They store vitamin A and prevent fibrosis
C. They are the primary site of ammonia detoxification
D. They phagocytose senescent red blood cells
RATIONALE: Hepatic stellate cells, when activated by injury, transdifferentiate into myofibroblasts
and secrete collagen, leading to fibrosis and cirrhosis. Their normal function includes vitamin A
storage, but activation promotes fibrosis. Ammonia detoxification occurs via urea cycle in
hepatocytes, and Kupffer cells phagocytose RBCs.
Q5 DIFFERENTIATE THE PATHOPHYSIOLOGIC MECHANISMS UNDERLYING
CARDIOVASCULAR, PULMONARY, RENAL, GI/HEPATIC, AND ENDOCRINE DISORDERS
In a patient with syndrome of inappropriate antidiuretic hormone (SIADH), which
laboratory finding is expected?
A. Serum osmolality <275 mOsm/kg and urine osmolality >100 mOsm/kg CORRECT
B. Serum osmolality >295 mOsm/kg and urine osmolality <100 mOsm/kg
C. Serum sodium >145 mEq/L and urine sodium <10 mEq/L
D. Serum potassium >5.5 mEq/L and metabolic alkalosis
RATIONALE: SIADH is characterized by hypotonic hyponatremia (serum osmolality <275) with
inappropriately concentrated urine (urine osmolality >100). Option B describes diabetes insipidus.
Hypernatremia and hyperkalemia are not typical of SIADH.
