,SECTION I — FOUNDATIONS OF PATHOPHYSIOLOGY
Question 1
Which statement best describes pathophysiology?
A. The study of normal anatomical structures
B. The study of how disease alters normal physiological processes
C. The study of medications and their chemical structures
D. The study of microorganisms only
Correct answer: B
Rationale: Pathophysiology examines functional changes produced by disease or injury.
Anatomy describes structure, while physiology describes normal function. Pharmacology
focuses on drugs, and microbiology focuses primarily on microorganisms.
Question 2
Which term describes the underlying cause of a disease?
A. Manifestation
B. Prognosis
C. Etiology
D. Pathogenesis
Correct answer: C
Rationale: Etiology refers to the cause or origin of a disease. Pathogenesis describes the
mechanisms through which the disease develops. Manifestations are observable signs and
symptoms, while prognosis concerns the expected outcome.
Question 3
A patient develops fever, fatigue, and muscle aches after acquiring influenza. These findings are
best classified as:
A. Etiologic factors
B. Clinical manifestations
C. Genetic mutations
D. Compensatory mechanisms
Correct answer: B
,Rationale: Fever, fatigue, and myalgia are clinical manifestations—the observable effects of the
disease. They do not represent the cause itself.
Question 4
Which cellular structure is primarily responsible for producing ATP?
A. Lysosome
B. Ribosome
C. Mitochondrion
D. Golgi apparatus
Correct answer: C
Rationale: Mitochondria generate most cellular ATP through oxidative phosphorylation. ATP
supplies energy for cellular transport, synthesis, movement, and other metabolic processes.
Question 5
Which process moves molecules across a membrane from an area of higher concentration to
lower concentration without requiring ATP?
A. Active transport
B. Diffusion
C. Endocytosis
D. Sodium-potassium pumping
Correct answer: B
Rationale: Diffusion is passive movement down a concentration gradient. Active transport
requires energy to move substances against their gradients.
Question 6
A patient has severe dehydration. Which intracellular change would most likely occur?
A. Cellular swelling
B. Cellular dehydration and shrinkage
C. Increased intracellular water
D. Increased cell volume from hypotonicity
Correct answer: B
, Rationale: Dehydration increases extracellular osmolality, causing water to move out of cells.
The cells therefore lose water and shrink.
Question 7
Which electrolyte is the major intracellular cation?
A. Sodium
B. Potassium
C. Calcium
D. Chloride
Correct answer: B
Rationale: Potassium is the predominant intracellular cation. Sodium is predominantly
extracellular.
Question 8
Which organelle contains enzymes responsible for intracellular digestion?
A. Lysosome
B. Nucleus
C. Ribosome
D. Centriole
Correct answer: A
Rationale: Lysosomes contain hydrolytic enzymes that digest damaged organelles, cellular
debris, and certain engulfed materials.
Question 9
Which cellular adaptation involves an increase in cell size?
A. Hyperplasia
B. Atrophy
C. Hypertrophy
D. Metaplasia
Correct answer: C
