NSG 5003 ADVANCED
PATHOPHYSIOLOGY PRACTICE EXAM
QUESTIONS WITH COMPLETE
SOLUTION GUARANTEED SUCCESS.
1. Which of the following cellular changes is considered a precursor to malignancy,
characterized by abnormal changes in size, shape, and organization of mature cells?
A. Metaplasia
B. Dysplasia
C. Hypertrophy
D. Atrophy
Answer: B
Conceptual Explanation: Dysplasia refers to abnormal changes in the size, shape, and
organization of mature cells and is often considered a pre-cancerous condition.
2. A patient with Cystic Fibrosis has a mutation in the CFTR gene. This condition is inherited in
which pattern?
A. Autosomal Dominant
B. Autosomal Recessive
C. X-linked Recessive
,D. Mitochondrial
Answer: B
Conceptual Explanation: Cystic Fibrosis is an autosomal recessive disorder, meaning an
individual must inherit two copies of the mutated gene to express the phenotype.
3. During the process of apoptosis, which enzyme family is primarily responsible for initiating
the execution phase of cell death?
A. Polymerases
B. Caspases
C. Kinases
D. Amylases
Answer: B
Conceptual Explanation: Caspases are a family of protease enzymes that play essential
roles in programmed cell death (apoptosis).
4. In Type II Hypersensitivity reactions, what is the primary mechanism of tissue damage?
A. Immune complex deposition in vessel walls
B. T-cell mediated cytotoxicity
C. IgE-mediated mast cell degranulation
D. Antibody binding to cell surface antigens leading to complement activation
, Answer: D
Conceptual Explanation: Type II hypersensitivity involves IgG or IgM antibodies binding
to antigens on the cell surface, leading to cell destruction via the complement system or
phagocytosis.
5. Which electrolyte imbalance is most commonly associated with the development of
Torsades de Pointes?
A. Hypokalemia
B. Hypercalcemia
C. Hypernatremia
D. Hypomagnesemia
Answer: D
Conceptual Explanation: Hypomagnesemia is a well-known risk factor for prolonging the
QT interval and triggering the specific polymorphic ventricular tachycardia known as
Torsades de Pointes.
6. What is the primary pathophysiological mechanism behind Myasthenia Gravis?
A. Autoantibody production against acetylcholine receptors at the neuromuscular junction
B. Destruction of the myelin sheath in the CNS
C. Dopamine depletion in the basal ganglia
D. Reduced production of GABA in the cortex
