Introduction
This examination assesses the student's understanding of the
pathophysiologic mechanisms underlying human disease. The test
evaluates comprehension of cellular injury, inflammation, infection,
immune responses, hematologic disorders, endocrine dysfunction,
and cardiovascular pathology. Questions are structured as multiple-
choice and scenario-based items requiring clinical reasoning,
application of pathophysiologic principles, and decision-making.
Emphasis is placed on the relationship between underlying
mechanisms and clinical manifestations.
SECTION ONE: QUESTIONS 1–100
1. Which of the following is the most common sign of infection?
A. Pain
B. Fever
,C. Swelling
D. Redness
🟢 B. Fever
🔴 RATIONALE: Fever is the most common systemic manifestation
of infection. It results from the release of endogenous pyrogens
that reset the hypothalamic set point. Pain, swelling, and redness
are localized signs of inflammation and may or may not be
present with infection.
2. A patient reports mild malaise and fatigue before developing
specific signs of illness. This stage of infection is known as:
A. Incubation period
B. Prodromal stage
C. Acute stage
D. Convalescent stage
🟢 B. Prodromal stage
🔴 RATIONALE: The prodromal stage is characterized by the
onset of nonspecific symptoms such as malaise, fatigue, and low-
grade fever before specific signs of the disease appear. The
incubation period is the time between exposure and onset of
symptoms. The acute stage is when specific symptoms are
present. The convalescent stage is recovery.
3. The incubation period of an infectious disease can last:
A. Only a few hours
B. Only a few days
C. Hours to years, depending on the pathogen
D. Always exactly 10 days
🟢 C. Hours to years, depending on the pathogen
,🔴 RATIONALE: The incubation period varies widely depending
on the pathogen. For example, influenza has an incubation period
of 1–4 days, while HIV can have an incubation period of years. The
duration depends on the organism's replication rate and host
factors.
4. Lipopolysaccharide (LPS) is found in the cell wall of which type
of bacteria?
A. Gram-positive bacteria
B. Gram-negative bacteria
C. Fungi
D. Viruses
🟢 B. Gram-negative bacteria
🔴 RATIONALE: Lipopolysaccharide (LPS), also known as
endotoxin, is a component of the outer membrane of gram-
negative bacteria. Gram-positive bacteria have peptidoglycan and
teichoic acids in their cell walls. Fungi have chitin and glucan.
Viruses have no cell wall.
5. Which of the following is a characteristic of viruses that
distinguishes them from bacteria?
A. They have a cell wall
B. They can reproduce independently
C. They require a host cell to replicate
D. They are susceptible to antibiotics
🟢 C. They require a host cell to replicate
🔴 RATIONALE: Viruses are obligate intracellular parasites that
require a host cell's machinery to replicate. They do not have a
cell wall, cannot reproduce independently, and are not susceptible
, to antibiotics. Bacteria have cell walls, reproduce independently,
and are susceptible to antibiotics.
6. Secondary endocrine disorders originate from:
A. The target gland itself
B. The pituitary gland, altering stimulation of a normal target
gland
C. The hypothalamus only
D. Peripheral tissues
🟢 B. The pituitary gland, altering stimulation of a normal target
gland
🔴 RATIONALE: Secondary endocrine disorders originate from the
pituitary gland, which produces trophic hormones that stimulate
target glands. When pituitary function is abnormal, the target
gland receives inadequate or excessive stimulation, leading to
hormone imbalance. Primary disorders originate in the target
gland itself.
7. Which anterior pituitary hormone deficiency is most
immediately life-threatening and requires immediate
replacement?
A. Growth hormone
B. Thyroid-stimulating hormone
C. Adrenocorticotropic hormone
D. Prolactin
🟢 C. Adrenocorticotropic hormone
🔴 RATIONALE: ACTH deficiency leads to adrenal insufficiency,
which can cause life-threatening hypotension, hypoglycemia, and
electrolyte imbalances. Immediate corticosteroid replacement is
required. Growth hormone and TSH deficiencies are serious but
