QUEStioN:S with coRREct aNSwERS
Based on the search results, I have compiled a comprehensive set of practice
Question:s covering pathophysiology, pharmacology, and physical examination
topics relevant to NURS 807. The questions include correct answers with
rationales where available.
SECTION 1: PATHOPHYSIOLOGY AND PHARMACOLOGY FOUNDATIONS
QUESTION: 1
What is the definition of pathophysiology?
A) Study of the structural changes in cells, tissues, and organs
B) Study of the functions of the human body
C) Cellular and organ changes that occur with disease and the effects on function
D) Study of drug interactions with living systems
Exact answer::C — Cellular and organ changes that occur with disease and
the effects on function
Rationale: Pathophysiology specifically addresses the cellular and organ changes
that occur with disease and how these changes affect function. Pathology studies
structural changes, while physiology studies normal body functions .
,QUESTION: 2
What is the initiation of most diseases?
A) Genetic mutation
B) Cellular injury
C) Environmental toxins
D) Bacterial infection
Exact answer::B — Cellular injury
Rationale: Cellular injury is the initiation point for most diseases. This can result
from various causes including physical forces, extremes of temperature, electrical
forces, radiation, and hypoxia .
QUESTION: 3
Which of the following is an example of a physical force that causes cellular
injury?
A) Free radicals
B) Hypoxia
C) Mechanical forces such as an ankle sprain
D) Impaired calcium homeostasis
Exact answer::C — Mechanical forces such as an ankle sprain
Rationale: Mechanical forces (trauma, sprains, fractures) are physical causes of
cellular injury. Other physical forces include extremes of temperature (causing
necrosis) and electrical forces .
, QUESTION: 4
A patient presents with a disease of unknown cause. This would be documented
as:
A) Iatrogenic
B) Nosocomial
C) Idiopathic
D) Congenital
Exact answer::C — Idiopathic
Rationale: Idiopathic means unknown etiology (cause). Iatrogenic refers to disease
arising from prescribed treatment, nosocomial means acquired from a healthcare
setting, and congenital means present at birth .
QUESTION: 5
Which type of injury is characterized by the body's ability to heal itself?
A) Irreparable injury
B) Necrosis
C) Reversible injury
D) Apoptosis
Exact answer::C — Reversible injury
