WCU PATHO 370 PATHOPHYSIOLOGY
MIDTERM EXAM BIG QUESTION BANK
(Q&AS WITH RATIONALES)
This premium study resource delivers a comprehensive bank of high-
yield multiple-choice practice questions explicitly tailored to help
nursing students pass their pathophysiology midterm exam on the
first try. Each question features highly detailed rationales, correct
answers highlighted in clear formatting, and multi-system clinical
case studies designed to mimic actual exam layouts. It is the ultimate
tool for rapid active recall, helping you confidently master cellular
adaptations, fluid and electrolyte shifts, acid-base balance, and
advanced organ-system alterations.
Question 1
A public health nurse organizes a community health fair to
provide free blood pressure screenings and routine lipid
panels for asymptomatic adults over the age of 40. Which
level of disease prevention does this intervention
represent?
A) Primary prevention
B) Secondary prevention
C) Tertiary prevention
D) Primordial prevention
Correct Answer: B) Secondary prevention
Rationale: Secondary prevention is strictly focused on
early disease detection, screening protocols, and
prompt intervention in asymptomatic individuals who
may have subclinical disease processes. This
minimizes disease progression. Primary prevention
seeks to prevent the onset of a disease entirely via
,vaccinations or health education, while tertiary
prevention focuses on managing established clinical
disease to limit disability and restore function.
Question 2
During a stress response, the body moves away from its
static, unyielding homeostatic baseline to dynamically
adjust systemic parameters and set points in response to
environmental demands. This active process of achieving
stability through physiological change is known as:
A) Homeostasis
B) Negative feedback failure
C) Allostasis
D) Pathogenesis
Correct Answer: C) Allostasis
Rationale: Allostasis is the dynamic, multi-system
regulatory process by which the body continuously
adapts its internal physiological set points to match
changing environmental or psychological stressors.
While homeostasis refers to maintaining a fixed,
optimal baseline parameter, allostasis refers to the
overall adaptive process that supports this balance
during stress. Pathogenesis refers to the specific
mechanism of disease development.
Question 3
Following an exposure to a viral pathogen, a patient
remains completely asymptomatic for several days while
the virus undergoes rapid replication within host cells. This
,specific interval between exposure to an injurious agent
and the first appearance of clinical signs or symptoms is
defined as the:
A) Prodromal period
B) Convalescent period
C) Latent or incubation period
D) Acute phase
Correct Answer: C) Latent or incubation period
Rationale: The latent (or incubation) period is defined
as the pre-symptomatic time window extending from
initial exposure to an injurious pathogen up to the
onset of the very first clinical signs or symptoms. The
prodromal period follows the incubation phase and is
characterized by the onset of mild, highly vague, non-
specific symptoms (e.g., fatigue, malaise). The
convalescent period is the recovery stage following
disease resolution.
Question 4
A 52-year-old patient with a 30 pack-year history of
cigarette smoking undergoes a routine diagnostic
bronchoscopy. The pathology report of the bronchial
biopsy reveals that the normal pseudostratified ciliated
columnar epithelial cells have been entirely replaced by
stratified squamous epithelial cells. This reversible cellular
adaptation is classified as:
A) Hyperplasia
B) Atrophy
C) Dysplasia
, D) Metaplasia
Correct Answer: D) Metaplasia
Rationale: Metaplasia is a fully reversible cellular
adaptation where one mature, differentiated adult cell
type is replaced by another mature adult cell type in
response to chronic environmental irritation or stress.
Squamous metaplasia in the bronchi of smokers
provides a tougher structural barrier but sacrifices
protective ciliated clearance functions. Dysplasia is
deranged, disordered cellular growth that serves as a
precursor to neoplasia, while hyperplasia refers to an
increase in total cell number.
Question 5
Following an acute ischemic stroke (cerebral infarction), a
patient experiences localized cell death within the brain
tissue. Histological analysis reveals that the ischemic brain
tissue has been broken down by hydrolytic enzymes into a
soft, liquid, fluid-filled cystic mass. Which type of necrosis
does this describe?
A) Coagulative necrosis
B) Liquefactive necrosis
C) Caseous necrosis
D) Fat necrosis
Correct Answer: B) Liquefactive necrosis
Rationale: Liquefactive necrosis occurs primarily in
the central nervous system following hypoxic or
ischemic injury. Because brain tissue is highly rich in
lipids and lysosomal hydrolytic enzymes, the dead
