QUESTIONS AND A NEW UPDATED STUDY GUIDE ACCURATE EXAM
COMPLETE APPROVED QUESTIONS AND CORRECT DETAILED ANSWERS
1. A patient with long-standing hypertension develops an enlarged left
ventricle while the number of cardiac muscle cells remains essentially
unchanged. The nurse recognizes that this structural change represents
which cellular adaptation to chronic increased workload?

B. Hypertrophy
C. Hyperplasia
D. Atrophy
Answer: B
2. A patient with chronic gastroesophageal reflux disease develops
replacement of the normal squamous epithelium of the lower esophagus
with a more protective columnar epithelium. Which pathophysiologic
process best explains this finding?
A. Dysplasia
B. Hyperplasia
C. Metaplasia
D. Hypertrophy
Answer: C
3. A hospitalized patient experiences prolonged hypotension that significantly
reduces oxygen delivery to skeletal muscle cells. Which cellular
consequence is most directly associated with inadequate oxygen availability
during the early stage of injury?
A. Decreased oxidative phosphorylation with reduced ATP production
B. Increased mitochondrial ATP production
C. Increased protein synthesis from enhanced ribosomal activity
D. Increased aerobic metabolism with greater oxygen consumption
Answer: A
1
, 4. A patient sustains severe ischemic injury to a tissue, and laboratory testing
later demonstrates cellular membrane rupture, enzyme leakage, and
inflammation surrounding the affected area. Which type of cell death best
explains these findings?
A. Apoptosis
B. Autophagy
C. Cellular adaptation
D. Necrosis
Answer: D
5. A patient develops a localized skin infection characterized by redness,
warmth, swelling, and tenderness. The nurse explains that the swelling is
primarily related to which inflammatory vascular event?
A. Decreased capillary permeability
B. Increased vascular permeability with movement of fluid and proteins into
tissues
C. Permanent arterial vasoconstriction
D. Reduced leukocyte migration into the tissue
Answer: B
6. A patient with acute bacterial pneumonia has an elevated neutrophil count
and develops purulent respiratory secretions. Which role of neutrophils
best explains their importance during this acute inflammatory response?
A. Production of antibodies against previous infections
B. Destruction of all infected cells through adaptive immunity
C. Rapid migration toward injured tissue where they participate in microbial
destruction
D. Suppression of vascular permeability during inflammation
Answer: C
7. A patient develops fever during a systemic inflammatory response. Which
mechanism most directly contributes to the elevation of body temperature
during inflammation?
A. Cytokine-mediated alteration of the hypothalamic temperature set point
2
, B. Permanent destruction of hypothalamic neurons
C. Decreased prostaglandin production in the hypothalamus
D. Suppression of leukocyte activity
Answer: A
8. A patient develops a localized abscess after bacterial infection. Which
description best distinguishes an exudate from a transudate in this clinical
situation?
A. Exudate contains little protein because vascular permeability is
unchanged
B. Exudate develops only when plasma oncotic pressure increases
C. Exudate is caused exclusively by decreased hydrostatic pressure
D. Exudate is protein-rich fluid that leaves vessels because of increased
vascular permeability
Answer: D
9. A patient with severe chronic inflammation has persistent activation of
immune cells and progressive tissue damage. Which characteristic most
strongly distinguishes chronic inflammation from acute inflammation?
A. It always occurs without tissue injury
B. It involves prolonged inflammatory activity with simultaneous tissue
injury and repair
C. It occurs only after bacterial infections
D. It is limited to several minutes
Answer: B
10. A patient is exposed to a microorganism for the first time and develops an
immune response involving antigen-specific lymphocytes. Which feature
distinguishes adaptive immunity from innate immunity?
A. Adaptive immunity is present immediately at birth without antigen
exposure
B. Adaptive immunity responds identically to every microorganism
C. Adaptive immunity develops antigen specificity and immunologic
memory
3
, D. Adaptive immunity functions independently of lymphocytes
Answer: C
11. A patient with an autoimmune disorder produces antibodies directed
against structures within the patient's own tissues. Which pathophysiologic
failure most directly contributes to this condition?
A. Failure of immune tolerance to self-antigens
B. Complete absence of innate immune defenses
C. Excessive erythrocyte production
D. Failure of platelet aggregation
Answer: A
12. A patient develops urticaria, bronchoconstriction, and hypotension within
minutes after exposure to an allergen. Which immune mechanism is most
consistent with this immediate hypersensitivity reaction?
A. Delayed T-cell-mediated destruction
B. Immune-complex deposition occurring over several days
C. Direct antibody destruction of red blood cells
D. IgE-mediated mast-cell activation with mediator release
Answer: D
13. A patient has repeated exposure to a specific antigen and develops a faster
and stronger response than occurred during the first exposure. Which
immunologic property accounts for this response?
A. Increased neutrophil production alone
B. Immunologic memory generated by adaptive immune cells
C. Permanent suppression of antibody production
D. Loss of antigen specificity
Answer: B
14. A patient with untreated HIV infection develops recurrent opportunistic
infections as the disease progresses. Which immune abnormality most
directly explains the increased susceptibility to infection?
A. Excessive production of erythrocytes
B. Increased platelet destruction
