CANADIAN EDITION CHAPTER 42
CERTIFICATION EVALUATION TEST COMPLETE
QUESTIONS AND CORRECT ANSWERS
◉ What does homeostasis refer to?
Answer: The tendency toward internal balance necessary for
optimal function across body systems.
◉ Name three examples of homeostasis in the human body.
Answer: Maintaining blood glucose levels, regulating body
temperature, and controlling blood gas concentrations.
◉ What is metabolism?
Answer: The physical and chemical changes occurring in the body
that are necessary for life.
◉ Define pathophysiology.
Answer: The study of mechanisms of disease, combining pathology
and physiology.
◉ What is the focus of pathophysiology?
,Answer: The interrelationships among structure, function, and
disease or disorder.
◉ What does pathogenesis mean?
Answer: The origin and development of disease, encompassing
when the disease process begins to when it presents itself.
◉ What is the difference between modifiable and nonmodifiable risk
factors?
Answer: Modifiable risk factors can be changed by the individual
(e.g., diet, smoking), while nonmodifiable risk factors cannot be
changed (e.g., genetics).
◉ What is the goal of studying pathogenesis?
Answer: To prevent disease from occurring or to facilitate early
diagnosis and intervention.
◉ What is etiology in the context of disease?
Answer: The precise cause of disease, which can be identifiable or
multifactorial.
◉ What is an idiopathic disease?
Answer: A disease with no known cause.
, ◉ Define nosocomial disease.
Answer: A disease resulting from exposure to infection in a
healthcare environment.
◉ What is an iatrogenic disease?
Answer: A disease that is an inadvertent result of medical treatment.
◉ What are clinical manifestations?
Answer: The presenting signs and symptoms of a disease.
◉ What is the difference between signs and symptoms?
Answer: Signs are observable or measurable expressions of a
disease, while symptoms are subjective indicators reported by the
patient.
◉ Give an example of a sign of herpes simplex.
Answer: Redness with raised, clear, fluid-filled vesicles on the lip.
◉ What are precipitating factors?
Answer: Triggers that promote the onset of clinical manifestations.
◉ What is the significance of understanding pathophysiology?
