NSG 5003: ADVANCED
PATHOPHYSIOLOGY EXAM
QUESTIONS WITH COMPLETE
SOLUTION GUARANTEED SUCCESS.
1. Which cellular adaptation process is characterized by the replacement of one mature cell
type by another, often less differentiated, cell type?
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Atrophy
Answer: B
Conceptual Explanation: Metaplasia is the reversible replacement of one mature cell type
by another, often due to chronic irritation or inflammation.
2. A 55-year-old male presents with severe chest pain and elevated serum troponin levels.
The underlying mechanism of cellular death in the myocardium is most likely:
A. Apoptosis
B. Coagulative necrosis
C. Autophagy
,D. Liquefactive necrosis
Answer: B
Conceptual Explanation: Coagulative necrosis typically occurs in the heart, kidneys, and
adrenal glands as a result of hypoxia or ischemia.
3. Which electrolyte imbalance is most commonly associated with a prolonged QT interval on
an EKG?
A. Hypocalcemia
B. Hypokalemia
C. Hypercalcemia
D. Hypermagnesemia
Answer: A
Conceptual Explanation: Hypocalcemia causes a prolonged QT interval by slowing down
the repolarization phase of the cardiac action potential.
4. What is the primary physiological drive for respiration in a patient with chronic obstructive
pulmonary disease (COPD) and chronic hypercapnia?
A. Elevated CO2 levels
B. Low serum pH
C. High bicarbonate levels
D. Low oxygen levels (hypoxic drive)
, Answer: D
Conceptual Explanation: In chronic hypercapnia, the central chemoreceptors become
desensitized to CO2, making peripheral chemoreceptors (sensitive to low O2) the primary
respiratory drive.
5. In the context of the Renin-Angiotensin-Aldosterone System (RAAS), what is the direct
effect of Angiotensin II?
A. Vasodilation
B. Systemic vasoconstriction
C. Sodium excretion
D. Inhibition of ADH
Answer: B
Conceptual Explanation: Angiotensin II is a potent vasoconstrictor that increases
systemic vascular resistance and stimulates aldosterone release.
6. Which type of hypersensitivity reaction is mediated by IgE and involves the release of
histamine from mast cells?
A. Type I
B. Type II
C. Type III
D. Type IV
