1) Pathophysiology as a discipline
Reference: Ch. 1 — Concepts of Health and Disease —
Pathophysiology
Stem: A student nurse asks why pathophysiology is studied in
nursing. The instructor explains that the subject links what
happens normally in the body with what changes when disease
develops. Which statement best reflects that explanation?
Options:
A. It focuses only on the microscopic appearance of diseased
tissue.
,B. It examines how altered function and structural changes
produce disease.
C. It describes only the causes of disease in populations.
D. It identifies the final outcome of a disease after treatment.
Correct Answer: B
Rationale:
B is correct. Pathophysiology connects normal physiology
with the structural and functional changes that occur in disease.
That linkage helps explain why specific clinical manifestations
appear.
A is incorrect. Microscopic tissue appearance is
morphologic/pathologic information, not the whole scope of
pathophysiology.
C is incorrect. Causes of disease in populations fall under
epidemiology, not the definition of pathophysiology.
D is incorrect. Final outcome is related to prognosis, not the
definition of the discipline.
Teaching Point: Pathophysiology explains how altered structure
and function create symptoms.
Citation: Norris, T. L. (2019). Porth’s Essentials of
Pathophysiology (5th ed.). Ch. 1.
2) Concept of health
Reference: Ch. 1 — Concepts of Health and Disease — Health
Stem: A client with well-controlled asthma says, “I am not sick,
,so I must be perfectly healthy.” Which response by the nurse
best reflects the chapter’s concept of health?
Options:
A. Health means the complete absence of any disease process.
B. Health is a dynamic state that involves more than the
absence of disease.
C. Health is defined only by laboratory values within normal
ranges.
D. Health is equivalent to being symptom-free at a single point
in time.
Correct Answer: B
Rationale:
B is correct. The chapter presents health as a broader,
dynamic concept rather than simply “no disease.” This supports
a more realistic nursing view of health status.
A is incorrect. A person may have a chronic condition and
still have meaningful health and function.
C is incorrect. Lab values alone do not define health.
D is incorrect. Health is not captured by one moment of
symptom review.
Teaching Point: Health is broader than the absence of illness.

Pathophysiology (5th ed.). Ch. 1.
3) Etiology
, Reference: Ch. 1 — Concepts of Health and Disease — Etiology
Stem: A client develops liver damage after years of heavy
alcohol use. The nurse identifies alcohol exposure as the factor
that initiated the disorder. Which term best describes this
factor?
Options:
A. Etiology
B. Prognosis
C. Morbidity
D. Prevalence
Correct Answer: A
Rationale:
A is correct. Etiology refers to the cause or origin of a
disease. In this case, alcohol exposure is the causal factor that
set the disease process in motion.
B is incorrect. Prognosis refers to the expected outcome,
not the cause.
C is incorrect. Morbidity refers to the effect of illness on
function or quality of life.
D is incorrect. Prevalence is a population measure of
existing cases.
Teaching Point: Etiology answers, “What caused the disease?”

Pathophysiology (5th ed.). Ch. 1.
