Pathophysiology Updated and Latest
Questions and Correct Answers with
Rationale - Portage Learning,,
Section 1: Fundamentals of Pathophysiology & Cellular Biology (1-15)
1. What is the best definition of pathophysiology?
A) The study of body structures and their relationships
B) The study of functional changes in the body due to disease
C) The study of drug interactions within the body
D) The study of psychological responses to illness
Correct ,,,,answer,,,: B
Rationale: Pathophysiology merges pathology (structural changes) with
physiology (functional changes) to explain how normal body processes are altered
by disease.
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 directly measured by an examiner. Signs are objective, measurable findings
(e.g., fever, rash).
,3. Which term refers to the predicted outcome of a disease?
A) Diagnosis
B) Etiology
C) Prognosis
D) Morbidity
Correct ,,,,answer,,,: C
Rationale: Prognosis is the likely course and outcome of a disease. Etiology is the
cause, diagnosis is the identification, and morbidity is the illness burden.
4. 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 a test's ability to correctly identify those with the
disease (True Positive Rate). "SnNOUT" (Sensitivity rules OUT disease).
5. A screening mammogram is an example of which prevention level?
A) Primary
B) Secondary
C) Tertiary
D) Quaternary
Correct ,,,,answer,,,: B
Rationale: Secondary prevention focuses on early detection of disease in
asymptomatic individuals to allow for early intervention and cure.
6. Vaccination against influenza is an example of:
A) Primary prevention
B) Secondary prevention
,C) Tertiary prevention
D) Diagnosis
Correct ,,,,answer,,,: A
Rationale: Primary prevention prevents disease before it occurs through measures
like vaccines, lifestyle changes, and health education.
7. The number of NEW cases of a disease in a population over a specific time
is:
A) Prevalence
B) Incidence
C) Morbidity
D) Mortality
Correct ,,,,answer,,,: B
Rationale: Incidence measures new cases developing in a population over time.
Prevalence measures total existing cases at a specific point.
8. A disease with no known cause is called:
A) Iatrogenic
B) Idiopathic
C) Nosocomial
D) Hereditary
Correct ,,,,answer,,,: B
Rationale: Idiopathic diseases have an unknown or spontaneous origin. Iatrogenic
conditions are caused by medical treatment.
9. Which of the following is an objective finding (sign) of disease?
A) Chest pain
B) Nausea
C) Elevated blood pressure
D) Dizziness
, Correct ,,,,answer,,,: C
Rationale: Elevated blood pressure (150/90 mmHg) is a measurable, objective
finding detected by a clinician. Chest pain, nausea, and dizziness are subjective
symptoms.
10. The time between exposure to a pathogen and first symptoms is the:
A) Prodromal period
B) Latent period (incubation)
C) Acute period
D) Terminal period
Correct ,,,,answer,,,: B
Rationale: The latent or incubation period is the interval between exposure to an
injurious agent and the first appearance of signs and symptoms.
11. Which organelle is responsible for ATP synthesis via oxidative
phosphorylation?
A) Lysosome
B) Golgi Apparatus
C) Mitochondria
D) Ribosome
Correct ,,,,answer,,,: C
Rationale: Mitochondria contain the electron transport chain and perform
oxidative phosphorylation to produce ATP, the cell's energy currency.
12. Which organelle contains hydrolytic digestive enzymes for intracellular
breakdown?
A) Nucleus
B) Ribosome
C) Lysosome
D) Smooth ER
