,📝 Chapter 1: Introduction to Pathophysiology
Question 1
Which of the following best defines pathophysiology?
A. The study of disease prevention and public health policy
B. The study of the structural changes caused by disease
C. The study of the functional changes that occur in the body as a result of a
disease
D. The analysis of symptoms reported by patients
✅ Correct Answer: C
💡 Rationale: Pathophysiology is the study of the functional changes
in the body that occur as a result of a disease process. It focuses on the
mechanisms underlying disease and how they affect normal physiological
processes.
Question 2
Which term describes the early stage of a disease when signs and symptoms
are not yet clinically apparent?
A. Exacerbation
B. Prodrome
C. Latent period
D. Convalescence
✅ Correct Answer: C
💡 💡 Rationale: The latent period is the time between exposure to
an etiologic agent and the appearance of symptoms, during which the
individual may be asymptomatic but physiological changes are already
underway.
3
, Question 3
What term refers to the cause of a disease?
A. Etiology
B. Pathogenesis
C. Clinical course
D. Prognosis
✅ Correct Answer: A
💡 Rationale: Etiology refers to the cause or origin of a disease. It
may be genetic, environmental, infectious, or a combination of multiple
factors.
Question 4
Which of the following best represents an iatrogenic condition?
A. A congenital heart defect
B. A viral infection
C. A skin burn from radiation therapy
D. A hereditary disorder
✅ Correct Answer: C
💡 Rationale: An iatrogenic condition is caused by a medical
treatment or diagnostic procedure. Radiation burns from therapy are a classic
example.
Question 5
Which of the following is a modifiable risk factor?
A. Age
B. Sex
C. Family history
D. Smoking
