PATH 370 – PATHOPHYSIOLOGY
MIDTERM EXAM 350 UNIQUE MULTIPLE-
CHOICE QUESTIONS WITH DETAILED
RATIONALES
SECTION 1: FOUNDATIONAL CONCEPTS (Questions 1–20)
1. Which of the following best defines pathophysiology?
A) The study of the structure of the body
B) The study of abnormalities in physiologic functioning of living beings
C) The study of disease classification
D) The study of drug interactions in the body
Answer: B
Rationale: Pathophysiology is the study of abnormalities in physiologic
functioning of living beings and seeks to reveal physiologic responses of
organisms to disease processes. It combines pathology (study of disease) with
physiology (study of normal body function).
2. A patient develops a disease from a cause that is unknown. This type of
etiology is termed:
A) Iatrogenic
B) Idiopathic
,C) Nosocomial
D) Congenital
Answer: B
Rationale: Idiopathic refers to a disease with an unknown cause. Iatrogenic
causes are treatment induced, nosocomial refers to hospital acquired, and
congenital indicates present at birth.
3. Which of the following represents the study of the causal factors that
provoke a particular disease?
A) Pathogenesis
B) Clinical manifestations
C) Etiology
D) Prognosis
Answer: C
Rationale: Etiology is the study of the causal factors that provoke a particular
disease or condition. Pathogenesis refers to the mechanism of disease
development.
4. A patient has been exposed to meningococcal meningitis but is not yet
demonstrating signs of this disease. This stage of illness is called the:
A) Prodromal stage
B) Latent stage
C) Acute stage
D) Chronic stage
,Answer: B
Rationale: The latent stage is when the disease process has been introduced to
the patient but signs and symptoms may not be apparent. The prodromal
stage is when signs and symptoms are mild and nonspecific.
5. Allostasis is best described as:
A) A state of equilibrium in the body
B) The process of achieving stability through change in response to stress
C) The body's inability to maintain homeostasis
D) A permanent state of physiological imbalance
Answer: B
Rationale: Allostasis is the process of achieving stability through change,
particularly in response to stress, and helps the body get back to homeostasis.
6. According to Selye's general adaptation syndrome, which phase is
characterized by the "fight or flight" response?
A) Resistance phase
B) Exhaustion phase
C) Alarm phase
D) Adaptation phase
Answer: C
Rationale: The alarm stage is the fight or flight response that occurs as a result
of a stressful stimulus. The resistance phase involves the body attempting to
return to homeostasis, and the exhaustion phase occurs when the body can no
longer return to homeostasis.
, 7. Which hormones are secreted during the stress response? (Select all that
apply)
A) Epinephrine
B) Norepinephrine
C) Cortisol
D) Aldosterone
Answer: A, B, C, D
Rationale: All of these hormones are secreted during the stress response.
Epinephrine and norepinephrine are secreted by the sympathetic nervous
system and adrenal medulla, while cortisol and aldosterone are
corticosteroids secreted by the adrenal cortex.
8. The sympathetic nervous system is primarily mediated by which
neurotransmitter?
A) Acetylcholine
B) Dopamine
C) Norepinephrine
D) Serotonin
Answer: C
Rationale: The sympathetic nervous system is mediated by norepinephrine.
The parasympathetic nervous system is primarily mediated by acetylcholine.
9. A disease that is native to a local region is called:
A) Epidemic
