APPLIED PATHOPHYSIOLOGY A CONCEPTUAL
APPROACH TO THE MECHANISMS OF DISEASE
FINAL PAPER 2026 QUESTIONS WITH
COMPLETE SOLUTIONS GRADED A+
◉ Which information is important for the nurse to understand about
the basis of disease? Answer: It affects single cells and cells of a
specific tissue.
Rationale: Because most diseases begin at the cellular level,
understanding of cell function is crucial to understanding the
disease process. Some diseases affect the cells of a single organ,
others affect the cells of a particular tissue type, and still others
affect the cells of the entire organism.
◉ The nurse knows that understanding the etiologic factors of a
disease is critical for healthcare providers to understand for what
reason? Answer: In order to prevent disease, it is important to
understand the agents and factors causing disease and how these
agents and factors affect the human organism and its organs
systems.
Rationale: Causes of disease are known as etiologic factors and
include a wide and varied group of agents and factors. Recognized
,etiologic factors are biologic agents (e.g., bacteria, viruses); physical
forces (e.g., trauma, burns, radiation); chemical agents (e.g., poisons,
alcohol); and nutritional excesses or deficits. At the molecular level,
it is important to distinguish between abnormal molecules and
molecules that cause disease. Most disease-causing agents are
nonspecific, and many different agents can cause disease of a single
organ. A single agent or traumatic event can, however, lead to
disease of a number of organs or systems.
◉ The nurse is attending a conference covering various perspectives
and patterns of disease across the United States and the world. Why
is this information important for nurses to know? Answer: Diseases
traverse continents and pose a threat to populations throughout the
world.
Rationale: The health of individuals is closely linked to the health of
the community and broader populations. The ability to traverse
continents in short periods of time leads to epidemics and
pandemics, as seen with COVID-19. Diseases that once were
confined to limited areas of the world now pose a threat to
populations throughout the world.
◉ Breast cancer screening programs are an example of primary
prevention of disease.
A. True
,B. False Answer: B. False
Rationale:
◉ The origin and development of disease is defined as _______________.
Answer: Pathogenesis
◉ ___________ prevention of disease is aimed at keeping diseases from
occurring in the first place. Answer: Primary
◉ Incidence is the number of __________ cases arising in a given
population during a specified time. Answer: new
◉ _________ is the study of mechanisms of disease. Answer:
Pathophysiology
◉ If a patient inadvertently experiences a complication as a result of
a medical procedure, that is an example of an iatrogenic disease.
A. True
B. False Answer: A. True
, ◉ ____________ is the study of disease occurrence in human
populations. Answer: Epidemiology
◉ A patient telling their provider they feel warm would be an
example of a sign, while a thermometer reading an elevated body
temperature of 39.2 degrees Celsius is a symptom.
A. True
B. False Answer: B. False
◉ Prevalence is the number of new cases of a disease in a population
in a given time.
A. True
B. False Answer: B. False
◉ Health, the perceived wholeness of body, mind, and spirit, and
illness, a state that results in suffering or distress, exist on a dynamic
continuum that can change over time.
A. True
B. False Answer: A. True
