NURS 6501 – Advanced Pathophysiology (Walden
University) Final Exam Coverage
Full Exam Content Coverage (Comprehensive)
This exam evaluates advanced understanding of disease
mechanisms across body systems, emphasizing cellular,
genetic, and systemic pathophysiology, clinical
manifestations, and compensatory responses.
1.
A 72-year-old male presents with chest pain and is
diagnosed with myocardial infarction. Cells in the affected
area show swelling and membrane blebbing without
nuclear destruction. Which mechanism explains this
finding?
A. Irreversible necrosis
B. Apoptosis activation
,C. Reversible cellular injury from ATP depletion
D. DNA fragmentation
Answer: C
Rationale: Early ischemia causes ATP depletion, impairing
ion pumps and leading to reversible swelling before
irreversible necrosis occurs.
2.
A patient with chronic acid reflux develops replacement of
esophageal squamous epithelium with columnar cells.
What adaptive cellular response is occurring in this
scenario?
A. Hyperplasia
B. Dysplasia
C. Metaplasia
D. Hypertrophy
Answer: C
Rationale: Chronic irritation leads to metaplasia, a
protective substitution of one mature cell type for another
better suited to the environment.
3.
,A 6-year-old child inherits cystic fibrosis after receiving
one defective allele from each parent. What genetic
principle explains this disease expression?
A. X-linked inheritance
B. Autosomal dominant inheritance
C. Autosomal recessive inheritance
D. Mitochondrial inheritance
Answer: C
Rationale: Autosomal recessive disorders require
inheritance of two defective alleles for clinical
manifestation.
4.
A patient develops localized redness, warmth, and swelling
following a bacterial infection. Which inflammatory
mediator is primarily responsible for vasodilation and
increased capillary permeability?
A. Dopamine
B. Histamine
C. Cortisol
D. Albumin
Answer: B
Rationale: Histamine released from mast cells promotes
, vasodilation and increased vascular permeability in acute
inflammation.
5.
A patient experiences rapid onset airway constriction and
hypotension after peanut exposure. Which immunologic
mechanism is primarily responsible for this reaction?
A. IgG-mediated cytotoxicity
B. Immune complex deposition
C. IgE-mediated mast cell degranulation
D. T-cell mediated delayed response
Answer: C
Rationale: Type I hypersensitivity involves IgE triggering
mast cell degranulation, causing anaphylaxis.
6.
A patient with persistent vomiting presents with elevated
blood pH and bicarbonate levels. Which underlying
pathophysiological mechanism explains this acid-base
imbalance?
A. Retention of carbon dioxide
B. Loss of hydrogen ions from gastric secretions
C. Increased lactic acid production
D. Decreased renal acid excretion
