QUESTIONS
1. Definition of Pathophysiology
Pathophysiology is a core concept in nursing and medicine because it helps
clinicians understand the changes that occur when normal physiological
processes are disrupted. It focuses on how diseases alter body function,
which is essential for accurate assessment, diagnosis, and treatment
planning. Which of the following best defines pathophysiology?
A. The study of normal physiological functions in healthy individuals
B. The study of structural anatomy at a cellular level
C. The study of functional changes in the body caused by disease or injury
D. The study of medical treatments and nursing interventions
Correct Answer: C
Explanation: Pathophysiology examines the altered biological processes
underlying diseases, linking cause to clinical manifestations.
2. Etiology of Disease
In understanding disease mechanisms, determining the etiology is crucial
because it allows healthcare professionals to identify the root causes, risk
factors, or triggering events that initiate disease processes. Etiology can be
classified as genetic, environmental, infectious, idiopathic, or multifactorial
depending on the condition. What does the term “etiology” specifically refer
to?
,A. The structural damage caused by disease
B. The cause or origin of a disease condition
C. The expected clinical outcome of disease
D. The changes in physiology after treatment
Correct Answer: B
Explanation: Etiology refers to the underlying cause or contributing factors
responsible for disease onset.
3. Concept of Pathogenesis
Understanding pathogenesis helps clinicians trace the entire journey of
disease from its initial cause to the development of cellular and systemic
dysfunction. It includes mechanisms such as inflammation, cellular injury,
immune response, and genetic mutations that progressively alter normal
function. Which statement best describes pathogenesis?
A. It refers to the visible symptoms patients report
B. It is the sequence of events leading from cause to disease manifestation
C. It focuses only on the genetic basis of disease
D. It is limited to the final clinical stage of illness
Correct Answer: B
Explanation: Pathogenesis is the biological pathway linking etiology to
clinical signs and disease progression.
4. Clinical Manifestations
Clinical manifestations provide the external evidence of internal
pathological changes, helping healthcare providers make accurate diagnoses.
They include both objective signs observed by clinicians and subjective
symptoms reported by patients, forming the basis for assessment and
intervention. Which of the following best defines clinical manifestations?
,A. Only measurable laboratory values indicating disease
B. Observable signs and subjective symptoms reflecting disease
C. Hidden cellular changes with no outward evidence
D. Purely genetic factors that predispose disease
Correct Answer: B
Explanation: Clinical manifestations are essential indicators of how disease
processes present externally.
5. Acute vs. Chronic Conditions
Acute and chronic conditions differ not only in duration but also in their
onset, progression, and impact on the body’s adaptive mechanisms. Acute
diseases typically present with sudden, intense symptoms over a short
period, whereas chronic diseases develop gradually and persist for months or
years, often requiring long-term management. Which statement best
distinguishes these two?
A. Acute conditions always cause permanent disability
B. Chronic diseases are always infectious in origin
C. Acute conditions have rapid onset and short duration, while chronic ones
are prolonged and persistent
D. Acute diseases occur only in childhood
Correct Answer: C
Explanation: The key difference lies in time course and progression, which
influence treatment approaches.
6. Risk Factors and Predispositions
Identifying risk factors is essential in pathophysiology because these
variables increase an individual’s vulnerability to developing disease, even
before clinical manifestations appear. Risk factors can include genetic
makeup, lifestyle behaviors, environmental exposures, and pre-existing
health conditions. Which of the following best describes a risk factor?
, A. A definitive cause of disease that guarantees onset
B. A variable that increases the likelihood of developing disease
C. A laboratory test that diagnoses pathology
D. A symptom appearing late in disease progression
Correct Answer: B
Explanation: Risk factors increase disease probability but do not
necessarily guarantee occurrence.
7. Idiopathic vs. Iatrogenic Conditions
In clinical practice, it is important to differentiate idiopathic from iatrogenic
diseases to avoid misattribution of causation. Idiopathic conditions have no
known cause, while iatrogenic conditions result from medical interventions,
such as procedures or medications, sometimes unintentionally. Which
statement accurately reflects this distinction?
A. Idiopathic diseases are always infectious
B. Iatrogenic conditions are caused by healthcare interventions, whereas
idiopathic ones have unknown causes
C. Both terms describe diseases caused by genetic inheritance
D. Idiopathic diseases are intentionally induced
Correct Answer: B
Explanation: Understanding these distinctions improves diagnosis and
helps prevent avoidable complications.
8. Cellular Homeostasis
Homeostasis is the body’s ability to maintain stable internal conditions, and
pathophysiological changes often arise when this balance is disrupted. Cells
respond to stressors by adapting through mechanisms like hypertrophy,
atrophy, or metaplasia to survive altered conditions. What does cellular
homeostasis primarily refer to?
