Exam 1 Advanced Physiology & Pathophysiology 2026/2027 50 Verified Questions & Answers
D'Youville University Prep 5 Core Domains Instant Download, with the strongest emphasis placed
on Analyze cellular injury, adaptation, and death mechanisms and predict their systemic
consequences, Integrate genetic, epigenetic, and immunologic principles to explain disease
susceptibility and progression, Interpret hemodynamic, respiratory, renal and and endocrine data to
identify underlying pathophysiologic derangements. 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 INJURY, ADAPTATION, AND DEATH MECHANISMS AND PREDICT
THEIR SYSTEMIC CONSEQUENCES
A cell is exposed to a toxin that opens the mitochondrial permeability transition
pore (mPTP). Which sequence of events BEST explains the resulting necrotic
(rather than apoptotic) cell death?
A. Cytochrome c release -> caspase-9 activation -> orderly DNA fragmentation
B. Loss of mitochondrial membrane potential -> ATP depletion -> failure of Na+/K+-ATPase ->
osmotic swelling and lysis CORRECT
C. Bcl-2 upregulation -> Bax inhibition -> preservation of outer membrane integrity
D. Phosphatidylserine externalization -> macrophage recognition -> lysosomal digestion without
inflammation
RATIONALE: mPTP opening dissipates the proton gradient, collapsing ATP synthesis; without
ATP, ion pumps fail, water enters, and the cell swells and lyses-the hallmark of necrosis. Option A
describes intrinsic apoptosis, C is cytoprotective, and D describes apoptotic clearance, none of
which follow mPTP opening.
Q2 ANALYZE CELLULAR INJURY, ADAPTATION, AND DEATH MECHANISMS AND PREDICT
THEIR SYSTEMIC CONSEQUENCES
A patient with a heterozygous gain-of-function mutation in PIK3CA (PI3K) shows
tissue overgrowth. Which molecular consequence most directly explains this
phenotype?
A. Constitutive AKT activation driving mTOR-dependent proliferation and survival CORRECT
B. Loss of PTEN-mediated dephosphorylation of PIP3
C. Impaired RAS GTPase activity with sustained MAPK signaling
D. Enhanced p53 tetramerization and cell-cycle arrest
RATIONALE: Gain-of-function PIK3CA increases PIP3, recruiting PDK1/AKT and activating
mTOR, which promotes growth and survival. PTEN loss (B) mimics but is not the mutation
described; RAS (C) and p53 (D) are unrelated pathways.

,Q3 ANALYZE CELLULAR INJURY, ADAPTATION, AND DEATH MECHANISMS AND PREDICT
THEIR SYSTEMIC CONSEQUENCES
In a patient with chronic obstructive pulmonary disease (COPD) and chronic CO
retention, which arterial blood gas pattern best reflects fully compensated
respiratory acidosis?
A. pH 7.32, PaCO 60 mmHg, HCO 30 mEq/L
B. pH 7.36, PaCO 60 mmHg, HCO 34 mEq/L CORRECT
C. pH 7.48, PaCO 30 mmHg, HCO 22 mEq/L
D. pH 7.40, PaCO 40 mmHg, HCO 24 mEq/L
RATIONALE: Full compensation returns pH toward normal; with chronic CO retention, renal HCO
reabsorption raises bicarbonate, yielding a near-normal pH. Option A is uncompensated, C is
respiratory alkalosis, and D is normal.
Q4 ANALYZE CELLULAR INJURY, ADAPTATION, AND DEATH MECHANISMS AND PREDICT
THEIR SYSTEMIC CONSEQUENCES
A patient with heart failure has an echocardiogram showing an E/A ratio <0.8 and
an E/e' ratio of 15. These findings are most consistent with which
pathophysiologic mechanism?
A. Impaired myocardial relaxation with elevated filling pressures (diastolic dysfunction)
CORRECT
B. Reduced contractility with decreased ejection fraction (systolic dysfunction)
C. Pericardial constriction limiting ventricular filling
D. Mitral regurgitation causing volume overload
RATIONALE: A low E/A ratio indicates impaired relaxation (grade I diastolic dysfunction), and
elevated E/e' reflects increased left atrial pressure. Systolic dysfunction would primarily reduce
ejection fraction, while constriction and regurgitation have different Doppler patterns.

, Q5 ANALYZE CELLULAR INJURY, ADAPTATION, AND DEATH MECHANISMS AND PREDICT
THEIR SYSTEMIC CONSEQUENCES
Which renal mechanism most directly explains the hyperkalemia observed in a
patient with metabolic acidosis from chronic kidney disease?
A. Increased aldosterone secretion enhancing K excretion
B. Shift of K into cells due to H buffering by intracellular proteins
C. Impaired distal Na delivery and reduced K secretion in the collecting duct CORRECT
D. Respiratory compensation causing hypoventilation and K retention
RATIONALE: In CKD, reduced nephron mass and distal Na delivery limit aldosterone-driven K
secretion, causing hyperkalemia. Acidosis shifts K out of cells (not in), and aldosterone is often
insufficient, so A and B are incorrect; D is not a direct renal mechanism.
Q6 ANALYZE CELLULAR INJURY, ADAPTATION, AND DEATH MECHANISMS AND PREDICT
THEIR SYSTEMIC CONSEQUENCES
A patient with type 1 diabetes presents with Kussmaul respirations and a fruity
breath odor. Which combination of laboratory findings is most consistent with
diabetic ketoacidosis (DKA)?
A. pH 7.30, HCO 12 mEq/L, anion gap 28, -hydroxybutyrate elevated CORRECT
B. pH 7.50, HCO 30 mEq/L, anion gap 12, glucose 600 mg/dL
C. pH 7.35, HCO 24 mEq/L, anion gap 10, lactate 8 mmol/L
D. pH 7.25, HCO 20 mEq/L, anion gap 18, PaCO 60 mmHg
RATIONALE: DKA features high-anion-gap metabolic acidosis with elevated ketones; option A
matches this. Option B is metabolic alkalosis, C suggests lactic acidosis without ketosis, and D
reflects respiratory acidosis.
