,CHAPTER 1: Introduction to Pathophysiology
PART I: MULTIPLE CHOICE (Q1–Q25)
Question 1: Which term is defined as the study of functional changes that accompany disease and
injury?
A) Pathophysiology
B) Physiology
C) Anatomy
D) Histology
ANS: A
Rationale: Pathophysiology focuses on the physiological processes that are altered by disease or injury,
explaining how and why signs and symptoms occur.
Question 2: Which term refers to the cause or origin of a disease?
A) Etiology
B) Pathogenesis
C) Clinical manifestations
D) Diagnosis
ANS: A
Rationale: Etiology refers to the cause or origin of a disease.
Question 3: Which of the following best describes pathogenesis?
A) The sequence of events in the development of a disease
B) The cause of a disease
C) The expected outcome of a disease
D) The treatment protocol for a disease
ANS: A
Rationale: Pathogenesis describes the mechanism by which a disease develops, including the chain of
cellular and tissue events from initial stimulus to manifestation.
Question 4: A patient presents with symptoms that are self-limiting and resolve quickly. This is best
described as:
A) Acute disease
B) Chronic disease
C) Subacute disease
D) Latent disease
ANS: A
Rationale: Acute diseases have a rapid onset and short duration and are often self-limiting.
Question 5: Which of the following is an example of an iatrogenic disease?
A) Liver damage caused by prescribed medications
B) A genetic mutation inherited from parents
C) A viral infection acquired in the community
D) A fracture resulting from a fall
ANS: A
Rationale: Iatrogenic diseases are those caused by medical treatment or diagnostic procedures.
,Question 6: The term "morbidity" refers to:
A) The state of being diseased or the prevalence of disease
B) The number of deaths caused by a disease
C) The rate of recovery from a disease
D) The genetic predisposition to a disease
ANS: A
Rationale: Morbidity refers to the condition of being ill or diseased, or the rate at which a disease occurs
in a population.
Question 7: A disease that is consistently present in a specific geographic region is called:
A) Endemic
B) Epidemic
C) Pandemic
D) Sporadic
ANS: A
Rationale: An endemic disease is one that is habitually present in a particular geographic area or
population.
Question 8: Which of the following best describes a sign of disease?
A) A measurable, objective finding detected by the examiner
B) A subjective experience reported by the patient
C) The underlying cause of the disease
D) The emotional response of the patient to illness
ANS: A
Rationale: Signs are objective findings that can be observed or measured, while symptoms are subjective
experiences reported by the patient.
Question 9: Which statement best describes the health-illness continuum?
A) It is a dynamic entity
B) It is based on objective data only
C) It represents two exclusive categories
D) It is focused on physical well-being only
ANS: A
Rationale: Health and illness are part of a dynamic continuum that includes the body, mind, and spirit.
Question 10: Which concept is often equated with health?
A) Homeostasis
B) Objectivity
C) An uneventful physical examination
D) The absence of symptoms
ANS: A
Rationale: Homeostasis, or the maintenance of a stable internal environment, is often equated with
health.
Question 11: What is the primary focus of pathophysiology?
A) The study of functional changes that accompany disease and injury
B) The study of normal human anatomy
, C) The study of surgical procedures and outcomes
D) The study of pharmacological drug interactions
ANS: A
Rationale: Pathophysiology focuses on the physiological processes that are altered by disease or injury.
Question 12: Which term describes the expected outcome of a disease?
A) Prognosis
B) Diagnosis
C) Etiology
D) Pathogenesis
ANS: A
Rationale: Prognosis refers to the expected or predicted outcome of a disease.
Question 13: A disease that spreads rapidly across a large geographic area is called:
A) Pandemic
B) Endemic
C) Sporadic
D) Localized
ANS: A
Rationale: A pandemic is a disease that spreads rapidly across a large geographic area, often worldwide.
Question 14: Which of the following is an example of a congenital disease?
A) Down syndrome
B) Hypertension
C) Type 2 diabetes
D) Lung cancer
ANS: A
Rationale: Congenital diseases are present at birth, such as Down syndrome.
Question 15: What is the difference between incidence and prevalence?
A) Incidence is the number of new cases; prevalence is the total number of cases
B) Incidence is the total number of cases; prevalence is the number of new cases
C) Incidence and prevalence are the same
D) Incidence refers to death; prevalence refers to illness
ANS: A
Rationale: Incidence is the number of new cases of a disease, while prevalence is the total number of
cases at a given time.
Question 16: Which of the following describes a symptom?
A) A subjective experience reported by the patient
B) A measurable, objective finding detected by the examiner
C) The underlying cause of the disease
D) The expected outcome of a disease
ANS: A
Rationale: Symptoms are subjective experiences reported by the patient.
