NURS 5315 Advanced Pathophysiology Exams 1–5 (2026/2027)
1. A 58-year-old male with a long-standing history of
hypertension presents with progressive left ventricular
hypertrophy noted on echocardiogram. The nurse practitioner
understands that the most likely pathophysiological
explanation for this compensatory mechanism is which of the
following?
A. Decreased myocardial oxygen demand due to reduced afterload
B. Increased cardiac muscle mass in response to chronic pressure
overload
C. Fibrotic replacement of myocardial cells causing ventricular dilation
D. Reduced sympathetic nervous system activation leading to cardiac
remodeling
Answer: B. Increased cardiac muscle mass in response to
chronic pressure overload
Rationale: Chronic hypertension increases afterload, forcing the left
ventricle to work harder. Over time, myocardial cells enlarge to
compensate for increased workload, resulting in left ventricular
hypertrophy.
2. A patient with poorly controlled type 2 diabetes mellitus
develops diabetic nephropathy. Which mechanism is
primarily responsible for glomerular damage in this
condition?
A. Autoimmune destruction of renal tubules
B. Increased ketone production causing tubular necrosis
,C. Persistent hyperglycemia leading to microvascular injury
D. Acute vasodilation of renal arteries causing hyperfiltration
Answer: C. Persistent hyperglycemia leading to microvascular
injury
Rationale: Chronic hyperglycemia damages glomerular capillaries
through advanced glycation end products and microvascular
inflammation, leading to diabetic nephropathy.
3. A nurse practitioner evaluates a patient with chronic
obstructive pulmonary disease (COPD) who demonstrates
barrel chest formation and prolonged expiration. Which
underlying pathophysiological process best explains these
findings?
A. Restrictive lung expansion from pleural fibrosis
B. Air trapping due to destruction of alveolar elastic tissue
C. Increased pulmonary compliance caused by fluid accumulation
D. Bronchial hyperreactivity leading to episodic bronchoconstriction
Answer: B. Air trapping due to destruction of alveolar elastic
tissue
Rationale: In emphysema, destruction of alveolar walls reduces elastic
recoil, causing air trapping and hyperinflation, which contributes to
barrel chest appearance.
4. A 35-year-old female develops Graves disease and reports
heat intolerance, weight loss, and palpitations. Which
physiological effect is directly caused by elevated thyroid
hormone levels?
A. Reduced basal metabolic rate
B. Increased sympathetic nervous system sensitivity
C. Suppression of catecholamine receptors
D. Decreased cardiac output and oxygen consumption
Answer: B. Increased sympathetic nervous system sensitivity
Rationale: Excess thyroid hormone increases beta-adrenergic receptor
sensitivity, leading to tachycardia, palpitations, anxiety, and heat
intolerance.
,5. A patient with liver cirrhosis develops ascites and
peripheral edema. Which pathophysiological mechanism most
directly contributes to fluid accumulation in this disorder?
A. Elevated plasma albumin concentration
B. Increased oncotic pressure within blood vessels
C. Portal hypertension and decreased albumin synthesis
D. Excessive renal filtration without sodium retention
Answer: C. Portal hypertension and decreased albumin
synthesis
Rationale: Cirrhosis impairs albumin production and increases portal
venous pressure, promoting movement of fluid into interstitial and
peritoneal spaces.
6. A patient experiences an acute myocardial infarction
involving the left anterior descending artery. Which cellular
event occurs first after ischemic injury?
A. Fibrosis and scar tissue formation
B. Mitochondrial dysfunction leading to ATP depletion
C. Neutrophil infiltration into necrotic tissue
D. Ventricular remodeling and dilation
Answer: B. Mitochondrial dysfunction leading to ATP
depletion
Rationale: Ischemia rapidly impairs oxidative phosphorylation,
causing ATP depletion and failure of cellular ion pumps.
7. A patient with chronic kidney disease demonstrates
metabolic acidosis. Which compensatory mechanism would
the nurse practitioner expect?
A. Hypoventilation to retain carbon dioxide
B. Increased respiratory rate to eliminate carbon dioxide
C. Reduced hydrogen ion excretion by the kidneys
D. Decreased bicarbonate buffering activity
, Answer: B. Increased respiratory rate to eliminate carbon
dioxide
Rationale: Metabolic acidosis stimulates respiratory compensation
through hyperventilation to reduce carbon dioxide and raise pH.
8. A patient diagnosed with syndrome of inappropriate
antidiuretic hormone secretion (SIADH) is at highest risk for
which electrolyte imbalance?
A. Hypernatremia
B. Hyperkalemia
C. Hyponatremia
D. Hypercalcemia
Answer: C. Hyponatremia
Rationale: Excess ADH causes water retention, diluting serum sodium
concentrations and leading to hyponatremia.
9. A patient develops iron deficiency anemia secondary to
chronic gastrointestinal bleeding. Which laboratory finding is
most characteristic of this disorder?
A. Elevated ferritin and macrocytosis
B. Low hemoglobin with microcytic hypochromic cells
C. Increased vitamin B12 and reticulocyte count
D. Elevated hematocrit with normocytic erythrocytes
Answer: B. Low hemoglobin with microcytic hypochromic
cells
Rationale: Iron deficiency anemia produces small, pale red blood cells
due to impaired hemoglobin synthesis.
10. A patient with systemic lupus erythematosus develops
glomerulonephritis. Which immunological mechanism is
primarily responsible for tissue damage?
A. Direct bacterial invasion of nephrons
B. Immune complex deposition within glomeruli
