PATH 370 – PATHOPHYSIOLOGY MIDTERM EXAM
PREDICTIVE QUESTIONS COMPLETE WITH 100%
CORRECT ANSWERS
1. Which of the following best describes the term "pathogenesis"?
A) The study of the cause of a disease
B) The clinical signs and symptoms of a disease
C) The mechanism by which a disease develops
D) The expected outcome of a disease
Answer: C
Rationale: Pathogenesis refers to the sequence of events in the
development of a disease, from the initial stimulus to the manifestation
of the disease. Etiology is the cause, clinical manifestations are the signs
and symptoms, and prognosis is the expected outcome.
2. A patient with a urinary tract infection develops sepsis. This
progression is an example of:
A) An iatrogenic condition
B) A complication
C) An idiopathic disease
D) A congenital anomaly
Answer: B
Rationale: A complication is a secondary disease or condition that
develops as a consequence of a primary disease. Iatrogenic conditions
,are caused by medical treatment, idiopathic has no known cause, and
congenital is present at birth.
3. A patient is in the resistance stage of Selye's General Adaptation
Syndrome. Which physiologic process is primarily occurring?
A) Activation of the "fight or flight" response
B) Mobilization of lipid stores for energy
C) Attempts by the body to return to homeostasis
D) Exhaustion of adrenal hormones leading to organ failure
Answer: C
Rationale: The resistance stage is characterized by the body's attempts
to adapt and return to a state of homeostasis through various
compensatory mechanisms. The alarm phase is the initial fight or flight
response.
4. The study of the functional changes that occur in the body as a
result of a disease process is known as:
A) Anatomy
B) Histology
C) Pathophysiology
D) Epidemiology
Answer: C
Rationale: Pathophysiology is specifically the study of the disordered
physiological processes associated with disease or injury. Anatomy is
structure, histology is tissues, and epidemiology is the study of disease
patterns in populations.
5. Which of the following is an example of a disease with a
multifactorial etiology?
A) Down syndrome (Trisomy 21)
,B) A gunshot wound
C) Coronary artery disease
D) Influenza A
Answer: C
Rationale: Multifactorial etiology involves multiple factors, such as
genetics, lifestyle, and environment. Coronary artery disease is
influenced by genetics, diet, smoking, and hypertension. Down
syndrome is chromosomal, a gunshot wound is physical injury, and
influenza is viral.
6. A patient has a genetic predisposition to type 2 diabetes but only
develops the disease after gaining a significant amount of weight. This
is an example of:
A) A congenital disorder
B) An iatrogenic disease
C) Gene-environment interaction
D) An idiopathic disease
Answer: C
Rationale: Gene-environment interaction refers to how environmental
factors (like diet) can trigger or modify disease expression in genetically
susceptible individuals.
7. The initial, mild, and often non-specific signs and symptoms that
precede the full development of a disease are known as the:
A) Latent period
B) Prodromal period
C) Acute phase
D) Chronic phase
Answer: B
Rationale: The prodromal period is characterized by early, mild, and
, often vague symptoms. The latent period is the time between exposure
and the first appearance of symptoms.
8. During the stress response, which hormone is primarily responsible
for the long-term adaptation and maintenance of blood pressure?
A) Epinephrine
B) Norepinephrine
C) Cortisol
D) Aldosterone
Answer: D
Rationale: Aldosterone is a mineralocorticoid that increases sodium
reabsorption and potassium excretion by the kidneys, leading to water
retention and increased blood pressure, providing long-term regulation.
9. A disease that occurs in a population at a higher-than-normal rate
for a specific period of time is called a(n):
A) Endemic disease
B) Epidemic disease
C) Pandemic disease
D) Sporadic disease
Answer: B
Rationale: An epidemic is a sudden increase in the number of cases of a
disease above what is normally expected in that population. Endemic is
constantly present, pandemic is global, and sporadic occurs irregularly.
10. A patient's cancer is in remission. This means that:
A) The disease has been cured and will not return.
B) The signs and symptoms of the disease have decreased or
disappeared.
C) The disease is actively spreading to other organs.
