Below is a comprehensive practice exam for NUR 2063 Essentials of Pathophysiology
Exam 1, based on modules covering cellular function, stress adaptation, fluid/electrolyte
balance, inflammation, immunity, and basic disease concepts. Each question includes the
correct answer and a detailed rationale to help you prepare.
SECTION 1: FOUNDATIONS OF PATHOPHYSIOLOGY
Question 1
Pathophysiology is best defined as:
A. Study of normal body function
B. Study of structural changes in cells and tissues
C. Study of functional changes caused by disease
D. Study of drug actions on the body
Answer: C – Study of functional changes caused by disease
Rationale: Pathophysiology focuses on abnormal physiological processes resulting from
disease. It differs from anatomy (structure) and normal physiology (function). Information
from the search results indicates pathophysiology includes four components: etiology
(causes), pathogenesis (disease development), clinical manifestations (signs/symptoms),
and treatment implications.
Question 2
The term that describes the maintenance of a stable internal environment is:
A. Pathogenesis
,B. Homeostasis
C. Etiology
D. Allostasis
Answer: B – Homeostasis
Rationale: Homeostasis refers to the body's ability to maintain internal equilibrium despite
external changes. Allostasis refers to the adaptive processes the body uses to achieve
homeostasis, not the state itself.
Question 3
A disease that develops slowly and lasts for months or years is considered:
A. Acute
B. Chronic
C. Latent
D. Nosocomial
Answer: B – Chronic
Rationale: Chronic diseases have prolonged courses (months to years), such as diabetes
or hypertension. Acute conditions develop rapidly and resolve quickly; latent refers to
dormant periods; nosocomial means acquired in healthcare settings.
Question 4
The cause or origin of a disease is referred to as:
A. Pathogenesis
B. Etiology
C. Clinical manifestation
D. Prognosis
Answer: B – Etiology
Rationale: Etiology identifies the causal factors for disease (e.g., bacteria, genetics,
environment). Pathogenesis is the sequence of events leading to disease manifestations;
prognosis predicts disease outcome.
,Question 5
Which of the following is an iatrogenic condition?
A. Diabetes mellitus
B. Infection caused by catheter insertion
C. Genetic disorder
D. Influenza acquired in the community
Answer: B – Infection caused by catheter insertion
Rationale: Iatrogenic conditions are unintended adverse outcomes resulting from medical
treatment or procedures. The catheter-related infection was caused by healthcare
intervention; the other options occur spontaneously or from community exposure.
Question 6
A complication is best described as:
A. A predictable outcome of disease
B. A new, unexpected problem related to disease or treatment
C. The cause of disease
D. The normal resolution of illness
Answer: B – A new, unexpected problem related to disease or treatment
Rationale: Complications are secondary, often unforeseen issues arising during a disease
course or after treatment, such as renal failure resulting from uncontrolled hypertension.
Question 7
The prodromal period of disease is characterized by:
A. Stage of full-blown symptoms
B. Recovery phase
C. Time of vague, nonspecific symptoms before full illness
D. Latent stage with no symptoms
, Answer: C – Time of vague, nonspecific symptoms before full illness
Rationale: The prodromal period involves mild, nonspecific manifestations (e.g., fatigue,
low-grade fever) before specific disease symptoms appear. The incubation period has no
symptoms; the acute phase has full symptoms.
Question 8
The study of disease patterns and distribution in populations is called:
A. Pathophysiology
B. Epidemiology
C. Histology
D. Pharmacology
Answer: B – Epidemiology
Rationale: Epidemiology analyzes disease distribution, patterns, and determinants in
defined populations. Florence Nightingale is credited as the first practicing epidemiologist.
Question 9
A patient receives a flu vaccine to prevent influenza. This is an example of which level of
prevention?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
Answer: A – Primary prevention
Rationale: Primary prevention aims to prevent disease before it occurs by reducing
susceptibility (immunizations, lifestyle changes). Secondary prevention is early detection
(screenings); tertiary prevention is rehabilitation after disease.
