Module 1: Fundamentals of Pathophysiology & Cellular Adaptation (Q 1-30)
1. What is the definition of pathophysiology?
A) The study of body structures
B) The study of functional changes in the body due to disease
,C) The study of drug interactions
D) The study of psychological disorders
Correct ,,,,answer,,,: B
Rationale: Pathophysiology is the convergence of pathology (study of structural
changes) and physiology (study of function). It explains how normal physiological
processes are altered by a disease state .
2. A patient reports feeling dizzy and nauseated. These are examples of:
A) Signs
B) Symptoms
C) Diagnoses
D) Prognoses
Correct ,,,,answer,,,: B
Rationale: Symptoms are subjective complaints reported by the patient that cannot
be measured directly by an examiner. Signs are objective, measurable findings
(e.g., fever, rash).
3. The proportion of people with a disease who test positive is called:
A) Specificity
B) Sensitivity
C) Prevalence
D) Incidence
Correct ,,,,answer,,,: B
Rationale: Sensitivity measures the test's ability to correctly identify those WITH
the disease (True Positive Rate). "SnNOUT" helps rule out disease.
4. A bodybuilder’s enlarged muscles result from:
A) Hyperplasia
B) Hypertrophy
,C) Metaplasia
D) Dysplasia
Correct ,,,,answer,,,: B
Rationale: Hypertrophy is an increase in the size of cells. Skeletal muscle cells
respond to increased workload (exercise) by enlarging, not by dividing.
5. Which type of cell death causes inflammation?
A) Apoptosis
B) Necrosis
C) Autophagy
D) Mitosis
Correct ,,,,answer,,,: B
Rationale: Necrosis is unregulated cell death caused by injury. It results in the
rupture of the cell membrane and release of cellular contents into the interstitial
space, triggering an inflammatory response.
6. Barrett’s esophagus is an example of:
A) Hypertrophy
B) Hyperplasia
C) Metaplasia
D) Dysplasia
Correct ,,,,answer,,,: C
Rationale: Metaplasia is the reversible replacement of one differentiated cell type
with another. In Barrett's esophagus, the normal squamous epithelium is replaced
by columnar epithelium due to chronic acid reflux.
7. Which organelle is responsible for ATP synthesis?
A) Lysosome
B) Golgi Apparatus
, C) Mitochondria
D) Ribosome
Correct ,,,,answer,,,: C
Rationale: The mitochondria contain the electron transport chain and perform
oxidative phosphorylation to produce adenosine triphosphate (ATP), the energy
currency of the cell.
8. Which cellular change is most likely to progress to malignancy?
A) Physiologic hypertrophy
B) Physiologic hyperplasia
C) Chronic metaplasia
D) High-grade dysplasia
Correct ,,,,answer,,,: D
Rationale: Dysplasia refers to disordered growth and atypical cell changes. High-
grade dysplasia involves significant cellular abnormalities and is considered a
direct precursor to carcinoma in situ and invasive cancer.
9. Lack of blood flow to a tissue is called:
A) Hypoxia
B) Ischemia
C) Anoxia
D) Necrosis
Correct ,,,,answer,,,: B
Rationale: Ischemia is reduced blood flow to a tissue. Hypoxia is low oxygen,
which can result from ischemia, but ischemia specifically refers to the blockage of
blood supply.
10. The process of white blood cells moving toward an injury site is:
A) Margination
B) Chemotaxis
