,Q1. A patient with chronic heart failure is started on a medication that inhibits the
reuptake of norepinephrine at the synaptic cleft. Which compensatory cardiovascular
response is most likely to be potentiated?
A. Vasodilation of peripheral arterioles
B. Increased heart rate and contractility
C. Reduced renin release from juxtaglomerular cells
D. Enhanced parasympathetic tone to the sinoatrial node
Correct Answer: B. Increased heart rate and contractility
Rationale: Norepinephrine reuptake inhibition increases synaptic norepinephrine, which
stimulates beta-1 adrenergic receptors in the heart, increasing heart rate and contractility.
This sympathomimetic effect can exacerbate heart failure by increasing myocardial oxygen
demand.
Why Wrong:
A - Norepinephrine primarily causes vasoconstriction via alpha-1 receptors, not
vasodilation.
C - Increased sympathetic activity stimulates renin release, not reduces it.
D - Norepinephrine enhances sympathetic, not parasympathetic, tone.

Q2. In a patient with sepsis, which finding indicates the transition from the
hyperdynamic phase to the hypodynamic phase of septic shock?
A. Warm, flushed extremities with bounding pulses
B. Increased cardiac output with decreased systemic vascular resistance
C. Cool, clammy skin with narrowed pulse pressure
D. Elevated lactate with respiratory alkalosis
Correct Answer: C. Cool, clammy skin with narrowed pulse pressure
Rationale: The hyperdynamic phase of septic shock is characterized by warm, flushed
skin, high cardiac output, and low systemic vascular resistance. Progression to the
hypodynamic phase involves myocardial depression, leading to decreased cardiac output,
cool clammy skin, and narrowed pulse pressure.
Why Wrong:
A - Warm, flushed extremities are characteristic of the hyperdynamic phase, not the
transition to hypodynamic.
B - Increased cardiac output with decreased SVR is the hallmark of the hyperdynamic
phase.
D - Elevated lactate with respiratory alkalosis can occur in both phases but does not
specifically indicate the transition.

, Q3. A researcher is studying a mutation that eliminates the function of the tumor
suppressor gene p53. Which cellular process is most directly impaired?
A. Apoptosis in response to DNA damage
B. Cell cycle progression from G1 to S phase
C. DNA repair mechanisms
D. Angiogenesis in hypoxic conditions
Correct Answer: A. Apoptosis in response to DNA damage
Rationale: p53 is a critical tumor suppressor that induces apoptosis when DNA damage is
irreparable. Loss of p53 function prevents apoptosis, allowing damaged cells to survive
and accumulate mutations, contributing to cancer development.
Why Wrong:
B - p53 inhibits cell cycle progression; its loss promotes progression, but the most
direct impairment is apoptosis.
C - p53 is involved in DNA repair indirectly by inducing repair genes, but its primary
role is apoptosis.
D - Angiogenesis is regulated by HIF-1 and VEGF, not directly by p53.

Basis of Disease, 10th Ed., Ch. 7
Q4. A patient with a history of recurrent calcium oxalate kidney stones is found to
have elevated serum calcium and low serum phosphate. Which laboratory finding
would best differentiate primary hyperparathyroidism from familial hypocalciuric
hypercalcemia?
A. 24-hour urinary calcium excretion
B. Serum parathyroid hormone (PTH) level
C. Serum 25-hydroxyvitamin D level
D. Bone mineral density at the lumbar spine
Correct Answer: A. 24-hour urinary calcium excretion
Rationale: In primary hyperparathyroidism, urinary calcium excretion is typically
elevated or normal, whereas in familial hypocalciuric hypercalcemia (FHH), urinary
calcium excretion is low due to a mutated calcium-sensing receptor. The 24-hour urinary
calcium-to-creatinine clearance ratio helps distinguish these conditions.
Why Wrong:
B - Both primary hyperparathyroidism and FHH have elevated PTH levels, so this
does not differentiate.
C - Vitamin D levels are not the primary differentiator.
D - Low bone density is common in primary hyperparathyroidism but not specific for
differentiation.
