Question:
A community health nurse teaches that health is more than the
absence of disease. A client with controlled hypertension,
regular exercise habits, and no activity limitations asks what this
means. Which statement best reflects the pathophysiologic
concept of health?
A. Health is a fixed state that exists only when no abnormality is
,present.
B. Health reflects the body’s ability to maintain stability despite
internal and external stressors.
C. Health means a person has no chronic conditions or risk
factors.
D. Health is determined only by laboratory values and physical
examination findings.
Correct Answer: B
Rationale — Correct Answer:
Health is a dynamic state of equilibrium in which the body
maintains function through adaptation and homeostasis. A
person may have a chronic condition and still be considered
relatively healthy if physiologic stability and function are
maintained. This concept is central to pathophysiology because
disease is often defined by loss of adaptive capacity.
Rationale — Incorrect Options:
A is incorrect because health is not fixed and can vary across
time and stress exposure.
C is incorrect because health is not limited to the complete
absence of chronic disease or risk factors.
D is incorrect because health includes function, adaptation, and
well-being, not only test results.
Teaching Point:
Health is adaptive stability, not perfect absence of disease.

2) Disease versus illness
Reference: Ch. 1 — Concepts of Health and Disease — Concepts
of Health and Disease
Question:
A client reports fatigue, worry, and loss of energy but has no
definitive abnormal test results yet. The nurse explains that the
client may be experiencing illness even before disease is
confirmed. Which concept supports this explanation?
A. Disease is always identical to the person’s experience of
symptoms.
B. Illness refers to the subjective experience of impaired health.
C. Disease can exist only when symptoms are visible to others.
D. Illness is a population-level measure of disease frequency.
Correct Answer: B
Rationale — Correct Answer:
Illness is the person’s subjective experience of being unwell,
including symptoms, distress, and functional impact. Disease
refers to an objective pathophysiologic process or
structural/functional abnormality. A client may feel ill before
diagnostic confirmation, especially in early or subclinical
disease.
, Rationale — Incorrect Options:
A is incorrect because disease and illness do not always match
exactly.
C is incorrect because many diseases are not immediately
visible or clinically obvious.
D is incorrect because population-level disease frequency
describes epidemiology, not illness.
Teaching Point:
Illness is lived experience; disease is pathophysiology.

Question:
A client with chronic lung disease maintains normal oxygen
saturation at rest but becomes dyspneic during exertion. The
nurse interprets this as evidence that the client’s body is
compensating, but only within limits. Which interpretation is
most accurate?
A. Compensation means the disease process has resolved.
B. Adaptation may preserve function until stress exceeds
physiologic reserve.
C. The client’s normal oxygen saturation proves there is no
