NURS 611 Advanced Pathophysiology Practice Exam
Course: Advanced Pathophysiology (Graduate Nursing) | Format: Multiple-choice with
rationale | Focus: Pathophysiological mechanisms across the lifespan
Section 1: Cellular Adaptation, Injury & Death
1. A patient with chronic hypertension exhibits thickening of the left ventricular
wall. Which cellular adaptation is the clinician observing?
A. Hypertrophy
B. Atrophy
C. Hyperplasia
D. Metaplasia
,Rationale: Hypertrophy is an increase in the size of cells, resulting in an increase in the
size of the organ. In the heart, this is a response to increased workload such as systemic
hypertension. It is distinct from hyperplasia, which involves an increase in the number of
cells .
2. Which mechanism is primarily responsible for the cellular swelling seen in
hypoxic injury?
A. Failure of the sodium-potassium pump
B. Increased protein synthesis
C. Increased aerobic metabolism
D. Decrease in intracellular osmotic pressure
Rationale: Hypoxia leads to a reduction in ATP production, which causes the sodium-
potassium (Na+/K+) pump to fail. As a result, sodium accumulates inside the cell,
drawing water in by osmosis. This leads to acute cellular swelling and is a reversible
stage of cell injury if oxygen is restored .
3. A 45-year-old male presents with severe chest pain. Lab tests reveal elevated
Troponin I and T. What is the most likely cellular mechanism occurring?
A. Apoptosis via extrinsic pathway
B. Autophagy
C. Coagulative necrosis
D. Liquefactive necrosis
Rationale: Coagulative necrosis is characteristic of hypoxic death in all tissues except
the brain; it is the primary process in myocardial infarction where cell proteins are
denatured .
4. Which cellular adaptation process is characterized by the replacement of one
mature cell type by another, often in response to chronic irritation?
,A. Dysplasia
B. Hyperplasia
C. Metaplasia
D. Hypertrophy
Rationale: Metaplasia is the reversible replacement of one mature cell type by another
less mature cell type. For example, ciliated columnar epithelium in the respiratory tract
of a smoker may be replaced by stratified squamous epithelium .
5. Ischemia-reperfusion injury is primarily associated with the generation of which
substances?
A. Hydrolytic enzymes
B. Lactic acid
C. Reactive oxygen species (ROS)
D. Mitochondrial DNA
Rationale: Reperfusion injury occurs when blood flow is restored to ischemic tissues,
leading to the formation of reactive oxygen species (free radicals) that cause further
membrane damage and calcium overload .
6. Which process involves the programmed cell death that prevents an
inflammatory response?
A. Necrosis
B. Autophagy
C. Oncosis
D. Apoptosis
Rationale: Apoptosis is an active process of cellular self-destruction (programmed cell
death) that does not elicit an inflammatory response, unlike necrosis .
, 7. In the cellular degradation process, what is the role of the ubiquitin-proteasome
pathway?
A. Synthesis of new proteins
B. Breakdown of abnormal or misfolded proteins
C. Production of ATP during hypoxia
D. Repair of double-strand DNA breaks
Rationale: The ubiquitin-proteasome pathway is the primary mechanism for proteolysis
in the cytosol, targeting misfolded or damaged proteins for degradation .
8. A 58-year-old patient with prolonged ischemia of the lower extremity develops
irreversible cell injury. The pathophysiologic hallmark that distinguishes
irreversible from reversible injury is:
A. Cellular swelling and fatty change
B. Membrane damage with mitochondrial dysfunction and calcium influx
C. Decreased ATP production alone
D. Hydropic change without organelle damage
Rationale: Irreversible injury is marked by severe membrane damage, mitochondrial
permeability transition, and massive calcium influx leading to necrosis. Reversible injury
shows swelling and fatty change without these terminal events .
Section 2: Genetics & Genetic Disorders
9. A 20-year-old female presents with a karyotype showing 45,X. Which clinical
diagnosis is associated with this finding?
A. Down Syndrome
B. Turner Syndrome
C. Klinefelter Syndrome
D. Fragile X Syndrome
Rationale: Turner syndrome is characterized by the presence of a single X chromosome,
denoted as 45,X. Clinical features often include short stature, webbing of the neck, and
