Advanced Pathophysiology
Comprehensive Finals Review (Qns & Ans)

1. Which of the following best describes the role of cytokines in
the inflammatory response?
A) They serve exclusively as neurotransmitters.
B) They act as signaling molecules that modulate immune
responses.
C) They inhibit apoptosis solely in tumor cells.
D) They are involved only in the clotting cascade.
ANS: B
©/2025
, Rationale: Cytokines are signaling molecules that play a
critical role in mediating and regulating immunity and
inflammation.
2. In the context of septic shock, which of the following factors
most significantly contributes to vasodilation?
A) Increased levels of norepinephrine
B) Elevated nitric oxide synthesis
C) Decreased circulating blood volume
D) Increased catecholamine release
ANS: B
Rationale: Nitric oxide is a potent vasodilator, and its
increased synthesis during septic shock leads to significant
vasodilation.
3. Which of the following conditions is most commonly
associated with a hypermetabolic state?
A) Hypothyroidism
B) Chronic fatigue syndrome
C) Sepsis
D) Anemia
ANS: C
©/2025
, Rationale: Sepsis often results in a hypermetabolic state as
the body attempts to fight off infection.
4. What is the primary pathological process in heart failure that
leads to decreased cardiac output?
A) Increased peripheral resistance
B) Myocardial ischemia
C) Excessive preload
D) Decreased contractility
ANS: D
Rationale: Decreased contractility of the heart muscle is a
key feature of heart failure, leading to reduced cardiac output.
5. Which of the following electrolyte imbalances is most likely
to occur in acute renal failure?
A) Hyperkalemia
B) Hypocalcemia
C) Hypernatremia
D) Hypochloremia
ANS: A
Rationale: Acute renal failure often causes the retention of
potassium, leading to hyperkalemia.

6. The _________ pathway of the coagulation cascade is
primarily activated by tissue injury.
ANS: extrinsic
Rationale: The extrinsic pathway is initiated by tissue factor
release upon vascular injury.
7. In diabetes mellitus, the lack of insulin or insensitivity leads
to elevated blood glucose and subsequent __________ production
from fatty acid metabolism.
ANS: ketones
Rationale: When insulin is deficient or cells are resistant, the
body turns to fat metabolism, producing ketones, which can lead
to ketoacidosis.
8. __________ disease is characterized by the progressive
degeneration of motor neurons leading to muscle weakness and
atrophy.
ANS: Amyotrophic lateral
Rationale: Amyotrophic lateral sclerosis (ALS) is associated
with the destruction of motor neurons in the brain and spinal cord.
