W.H.O. definition of health
A state of complete physical, mental, and social wellbeing and not merely the absence of disease and infirmity.
What are some determinants of health?
Genetics, stress levels, physical and social environments, government policies and interventions, access to quality health care.
Disease
any deviation from or interruption of the normal structure/function of the body which is manifested by specific symptoms or signs
Symptom
What the patient tells you.
Sign
What is observable
Asymptomatic vs Symptomatic
Asymptomatic is when the disease is present but without any associated symptoms or discomfort.
Symptomatic is when the disease is present with symptoms
Describe the disease continuum
The left side has the end of life, severe, life-threatening illness. The Right side has the WHO definition of health. Mostly everyone falls in between these 2 spots, with the right side being the goal

Exam quote #1
Pathophysiology provides basis for preventive & therapeutic health measures and nursing practice
etiologic factors
the reason something is in the body
Concepts of etiology to note
1 disease agent can affect multiple organs
Multiple disease agents can affect 1 organ
Most diseases have many causes.
Risk factors (definition and types)
Predisposing conditions for a particular disease
Congenital (present at birth) or Acquired (caused by events that occur after birth)
pathogenesis
The sequence of events that take place from initial contact to expression of disease
describe how the disease process evolves
morphology
gross anatomical and microscopic changes that are characteristic of a disease
Lesion
ANY discontinuity of a body organ or itssue
syndrome
a compilation of signs & symptoms that show a specific disease state
diagnosis
nurses will never do this
designation as to the nature or cause of a health problem based on information from health history and physical examination
Diagnostic tests and procedures
assist in diagnosis to weigh risks against benefits
may be invasive or noninvasive
validity vs reliability
validity is how correct a measurement is while reliability is how repeatable the measurement is
reference ranges
Healthy volunteers are tested to create a frequency distribution/bell curve to reference patient levels
acute vs chronic vs subacute disease
acute disorders are short-lived and relatively severe
chronic disorders have a long-term process and continuous symptoms
subacute disease is somewhere between acute and chronic disease
preclinical vs subclinical vs clinical vs carrier
preclinical is when the disease is not evident but is destined to progress into clinical
subclinical is when the disease is not evident and not destined to become clinically apparent
clinical is when the disease is evident and characterized by signs and symptoms
carrier status is when someone harbors the organism and can spread it but does not have the disease
stress as a transitional or interactional concept
how the person reacts to stress/a situation will impact how they physically react/develop/fight a diseased state
homeostasis (another word for it and definition)
allostasis
purposeful maintenance of a stable internal environment by physiologic processes that oppose change
*does not occur by chance but rather by organized self-governance
