PATHOPHYSIOLOGY PRACTICE EXAM
QUESTIONS AND VERIFIED ANSWERS|
100% CORRECT |GRADE A –
CHAMBERLAIN
1. A patient exhibits a replacement of one mature cell type by another less mature cell type in
the bronchial lining due to chronic smoking. This cellular adaptation is known as:
A. Metaplasia
B. Hyperplasia
C. Atrophy
D. Dysplasia
Answer: A
Conceptual Explanation: Metaplasia is the reversible replacement of one mature cell type
by another, often less differentiated, cell type in response to chronic irritation.
2. In the development of cardiogenic shock, what is the primary pathophysiological event?
A. Systemic vasodilation
B. Increased preload
C. Hypovolemia
,D. Decreased cardiac output despite adequate intravascular volume
Answer: D
Conceptual Explanation: Cardiogenic shock is defined by the heart’s inability to pump
sufficient blood to meet the body’s metabolic needs despite adequate fluid volume.
3. Which electrolyte imbalance is most commonly associated with the development of tall,
peaked T-waves on an EKG?
A. Hyperkalemia
B. Hypocalcemia
C. Hypernatremia
D. Hypomagnesemia
Answer: A
Conceptual Explanation: Hyperkalemia affects the repolarization phase of the cardiac
action potential, leading to narrowed and peaked T-waves.
4. A 55-year-old male presents with symptoms of Parkinson’s disease. The primary defect
involves the depletion of dopamine in which area of the brain?
A. Cerebellum
B. Substantia nigra
C. Cerebral cortex
D. Amygdala
, Answer: B
Conceptual Explanation: Parkinson’s disease is characterized by the degeneration of
dopamine-producing neurons in the substantia nigra pars compacta.
5. Which type of hypersensitivity reaction is mediated by IgE antibodies and involves the
release of histamine from mast cells?
A. Type IV
B. Type II
C. Type III
D. Type I
Answer: D
Conceptual Explanation: Type I hypersensitivity is an immediate allergic reaction
mediated by IgE binding to mast cells.
6. What is the primary mechanism behind the development of Type 2 Diabetes Mellitus?
A. Absolute insulin deficiency
B. Insulin resistance and relative insulin deficiency
C. Autoimmune destruction of beta cells
D. Excessive glucagon secretion
Answer: B
