Question 1
What is pathophysiology primarily concerned with?
(A) The treatment of diseases
(B) The study of functional changes in the body due to disease
(C) The prevention of diseases
(D) The diagnosis of conditions
Correct Option: (B)
Rationale: Pathophysiology focuses on the study of functional changes in
the body resulting from disease processes, helping to understand how
diseases affect normal functions.
Question 2
What is homeostasis?
(A) A state of disease
(B) The body’s ability to maintain a stable internal environment
(C) A type of infection
(D) A method of treatment
Correct Option: (B)
Rationale: Homeostasis refers to the body’s ability to maintain a stable
internal environment despite external changes, crucial for survival and
health.
Cellular Responses
Question 3
What is apoptosis?
(A) Uncontrolled cell growth
,(B) Programmed cell death
(C) Cell division
(D) Inflammation
Correct Option: (B)
Rationale: Apoptosis is a controlled process of programmed cell death
that occurs naturally in the body as a way to eliminate damaged or
unnecessary cells.
Question 4
What type of cellular adaptation occurs in response to chronic irritation?
(A) Hypertrophy
(B) Metaplasia
(C) Atrophy
(D) Hyperplasia
Correct Option: (B)
Rationale: Metaplasia is an adaptive response where one type of cell is
replaced by another type that is better suited to withstand chronic irritation
or stress.
Inflammation and Healing
Question 5
What is the primary purpose of inflammation?
(A) To decrease blood flow
(B) To localize and eliminate pathogens
(C) To promote cell apoptosis
(D) To increase energy expenditure
Correct Option: (B)
Rationale: Inflammation is a protective response that aims to localize and
eliminate pathogens, as well as facilitate tissue repair.
Question 6
What are the cardinal signs of inflammation?
(A) Fever, chills, and fatigue
,(B) Redness, heat, swelling, pain
(C) Nausea and vomiting
(D) Cough and congestion
Correct Option: (B)
Rationale: The cardinal signs of inflammation include redness, heat,
swelling, and pain, which result from increased blood flow and vascular
permeability.
Immune Response
Question 7
What is the role of antibodies in the immune response?
(A) To directly kill pathogens
(B) To recognize and neutralize foreign antigens
(C) To promote inflammation
(D) To activate T-cells
Correct Option: (B)
Rationale: Antibodies are proteins produced by B-cells that recognize and
bind to specific foreign antigens, neutralizing pathogens and marking them
for destruction.
Question 8
What type of immunity is produced after vaccination?
(A) Passive immunity
(B) Active immunity
(C) Innate immunity
(D) Natural immunity
Correct Option: (B)
Rationale: Active immunity is produced when the body generates a
response to a vaccine, leading to the formation of memory cells for future
protection against the pathogen.
Genetic Disorders
, Question 9
What is a common characteristic of autosomal dominant disorders?
(A) They require two copies of the mutated gene
(B) They can be expressed with one copy of the mutated gene
(C) They are always lethal
(D) They affect only males
Correct Option: (B)
Rationale: Autosomal dominant disorders can be expressed with just one
copy of the mutated gene, meaning only one parent needs to pass on the
gene for the disorder to manifest.
Question 10
What is the genetic basis of cystic fibrosis?
(A) Autosomal dominant mutation
(B) Autosomal recessive mutation
(C) X-linked dominant mutation
(D) Multifactorial inheritance
Correct Option: (B)
Rationale: Cystic fibrosis is caused by an autosomal recessive mutation in
the CFTR gene, requiring both copies of the gene to be mutated for the
disease to manifest.
Pathophysiology of Specific Conditions
Question 11
What is the hallmark of chronic obstructive pulmonary disease (COPD)?
(A) Increased lung elasticity
(B) Airflow limitation
(C) Normal respiratory function
(D) Decreased mucus production
Correct Option: (B)
Rationale: The hallmark of COPD is airflow limitation due to the
combination of chronic bronchitis and emphysema, leading to difficulty in
exhaling air from the lungs.
