PREP 2026 QUESTIONS WITH VERIFIED ANSWERS DETAILED
RATIONALES GRADED A+
Part I: Introduction to Pathophysiology and Cellular Responses (Questions 1–30)
1. The term pathophysiology is best defined as which of the following?
A. The laboratory study of tissue changes caused by disease
B. The study of functional or physiological changes caused by disease
C. The study of drug actions in the body
D. The classification of surgical procedures
Rationale: Pathophysiology focuses on the functional and physiological alterations
that occur with disease, distinguishing it from pathology, which emphasizes
structural and laboratory changes.
2. A disease with an unknown cause is best classified as which of the following?
A. Iatrogenic
B. Idiopathic
C. Congenital
D. Nosocomial
Rationale: Idiopathic diseases arise without a clearly identified cause, whereas
iatrogenic diseases result from medical treatment and congenital diseases are
present at birth.
3. An iatrogenic disease is most likely caused by which of the following?
1|Page
,Page 2 of 78
A. A medical treatment or procedure
B. Genetic inheritance
C. Environmental exposure only
D. Nutritional deficiency only
Rationale: Iatrogenic conditions are unintended consequences of medical care,
such as adverse drug reactions or complications of procedures.
4. Homeostasis is best described as which of the following?
A. A permanent state of disease
B. The body’s maintenance of a stable internal environment
C. The absence of all stressors
D. A fixed, unchanging physiological state
Rationale: Homeostasis is the dynamic equilibrium through which the body
maintains internal stability despite external and internal changes.
5. Atrophy is best defined as which of the following?
A. An increase in cell size
B. A decrease in cell size
C. An increase in cell number
D. Disordered cell growth
Rationale: Atrophy refers to a reduction in cell size, often due to disuse, ischemia,
or hormonal changes.
6. Hypertrophy is characterized by which of the following?
A. A decrease in cell size
B. An increase in cell size
C. An increase in cell number
D. Abnormal cell differentiation
Rationale: Hypertrophy is an increase in cell size, commonly seen in skeletal
muscle with exercise or cardiac muscle in hypertension.
7. Hyperplasia refers to which of the following?
2|Page
,Page 3 of 78
A. A decrease in cell size
B. An increase in cell size
C. An increase in cell number
D. Malignant transformation
Rationale: Hyperplasia involves an increase in the number of cells, often in
response to hormonal stimulation or chronic irritation.
8. Dysplasia is best described as which of the following?
A. Normal cellular adaptation
B. Disordered, atypical cell growth that is not necessarily malignant
C. Complete loss of cellular differentiation
D. Programmed cell death
Rationale: Dysplasia represents disordered growth and atypical cellular
appearance; it may be reversible and does not always progress to malignancy.
9. Anaplasia is characterized by which of the following?
A. A loss of cellular differentiation, often indicating malignancy
B. Reversible cellular adaptation
C. Increased cell size only
D. Programmed cell death
Rationale: Anaplasia reflects a lack of differentiation, a hallmark of malignant cells
that lose normal structural and functional characteristics.
10. Which of the following best describes ischemia as a cause of cell injury?
A. Inadequate blood supply leading to oxygen and nutrient deprivation
B. Excessive oxygen delivery
C. Autoimmune destruction
D. Genetic mutation
Rationale: Ischemia reduces blood flow, depriving cells of oxygen and nutrients
and impairing removal of metabolic wastes, leading to cell injury.
11. Necrosis is best described as which of the following?
3|Page
, Page 4 of 78
A. Unregulated cell death resulting from injury
B. Programmed cell death
C. Normal cell turnover
D. Reversible cell swelling
Rationale: Necrosis is uncontrolled cell death caused by injury, infection, or
ischemia, often triggering inflammation.
12. Apoptosis differs from necrosis in which of the following ways?
A. Apoptosis causes inflammation, whereas necrosis does not.
B. Apoptosis is programmed and does not trigger inflammation.
C. Apoptosis is always pathological.
D. Necrosis is reversible.
Rationale: Apoptosis is a regulated, energy-dependent process of programmed
cell death that avoids inflammation, unlike necrosis.
13. A sequela is best defined as which of the following?
A. The initial cause of a disease
B. A condition that results from a disease
C. A predisposing risk factor
D. The absence of symptoms
Rationale: A sequela is a consequence or complication that follows a disease, such
as chronic kidney disease after hypertension.
14. The incidence of a disease refers to which of the following?
A. The number of existing cases at a given time
B. The number of new cases occurring in a population over a period
C. The death rate from the disease
D. The severity of the disease
Rationale: Incidence measures new cases over time, whereas prevalence
measures all existing cases at a point in time.
15. The prevalence of a disease is best described as which of the following?
