With questions and answers with rationales
/verified/latest update/already A+ 2026/2027
Instructions: Choose the best answer for each of the following multiple-choice
questions.
Section 1: General Concepts of Pathophysiology (Chapters 1-5)
Which of the following best describes the term "pathogenesis"?
A. The identification of a specific disease.
B. The cause of a disease.
C. The sequence of cellular and tissue events that occur from initial contact with a causative
agent to the expression of disease.
D. The signs and symptoms of a disease.
Answer: C
Rationale: Pathogenesis is the development or evolution of a disease, including the sequence of
events from the initial stimulus to the final clinical manifestations. A is diagnosis, B is etiology,
and D is clinical manifestations.
A patient has a fever, body aches, and a sore throat. These are examples of:
A. Etiology
B. Pathogenesis
C. Signs
,D. Symptoms
Answer: D
Rationale: Symptoms are subjective feelings reported by the patient, such as pain, nausea, or
body aches. Signs are objective findings that can be observed or measured by someone else, like
a fever (measured with a thermometer) or a rash.
Atrophy of an organ or tissue is best described as:
A. An increase in the number of cells.
B. A decrease in the size of individual cells.
C. A change in one cell type to another.
D. Disordered cell growth.
Answer: B
Rationale: Atrophy is a decrease in the size of a cell, leading to a reduction in the size of the
tissue or organ. A is hyperplasia, C is metaplasia, and D is dysplasia.
Which type of cellular adaptation is considered a precursor to cancer?
A. Hypertrophy
B. Metaplasia
C. Dysplasia
D. Atrophy
Answer: C
Rationale: Dysplasia is characterized by deranged cell growth of a specific tissue and is
considered a premalignant condition. While metaplasia is a change in cell type and can be a
,precursor, dysplasia represents more advanced abnormal changes that can progress to
malignancy.
The primary difference between reversible and irreversible cell injury is:
A. The presence of cell swelling.
B. The ability of the cell to return to normal function.
C. The duration of the injury.
D. The type of injurious agent.
Answer: B
Rationale: The defining characteristic is whether the cell can recover and return to its normal
state. Irreversible injury leads to cell death (necrosis or apoptosis).
Which form of cell death is a normal, genetically programmed process?
A. Necrosis
B. Apoptosis
C. Ischemia
D. Hypoxia
Answer: B
Rationale: Apoptosis is programmed cell death, a normal physiological process for eliminating
unwanted cells during development and for maintaining tissue homeostasis. Necrosis is a
pathological form of cell death.
Coagulative necrosis is most likely to occur in which of the following organs after an ischemic
event?
A. Brain
, B. Heart
C. Lung
D. Liver
Answer: B
Rationale: Coagulative necrosis primarily occurs in tissues with a high protein content, like the
heart, kidney, and spleen, where ischemia causes protein denaturation. The tissue becomes firm
and opaque. The brain typically undergoes liquefactive necrosis.
The movement of water across a semipermeable membrane from an area of lower solute
concentration to an area of higher solute concentration is called:
A. Diffusion
B. Active transport
C. Osmosis
D. Filtration
Answer: C
Rationale: Osmosis is the passive movement of water. Diffusion is the movement of solutes,
active transport requires energy, and filtration is the movement of water and solutes together due
to hydrostatic pressure.
Edema can be caused by all of the following EXCEPT:
A. Increased capillary hydrostatic pressure.
B. Decreased plasma oncotic pressure.
C. Lymphatic obstruction.
D. Increased plasma protein levels.
