Class 1: Pathophysiology and Disease Flashcards
disease
an objective state of ill health that can be detected by medical science
- body is invaded by microorganisms, bacteria or virus.
- disruption in your body
- may be defined as an abnormality of the structure of function of a part, organ or system
illness
subjective experience of loss of health
-some people experience it different then others
health
objective process characterized by functional stability, balance and integrity.
- till the mid 1900’s health was defined as the freedom from disease
- in 1948 the WHO proposed the definition of health as “a state of complete physical, mental and social well being and not merely an absence of disease or infirmity”
wellness
- an active process of becoming aware of and making choices toward a healthy and fulfilling life.
- more then being free of illness, it is a dynamic process of change and growth.
- multidimensional (a bunch of different choices that affect our wellness)
- subjective experience
inflammation
the bodys cellular response to injury or infection. it is a protective vascular reaction that delivers fluid, blood products and nutrients to an area of injury
trauma
can refer to any physical damage or in psychological terms can refer to feelings of fear, threat, and persistent reliving after witnessing emotionally painful or shocking event
chronic disease
slow progression disease and long duration. primarily occur in people over 65 and affect quality of life and mobility.
holism
physical health is affected by beliefs, expectations and thoughts. it is not fully understood yet, but it states that body, mind and spirit are interconnected. when one part of the body faces a challenge or receives support others are affected
resiliency
the ability to be resourceful, be flexible and recover from stressful situations and return to prior levels of functioning
infection
state produced by the establishment of one or more bacteria, protozoans, or viruses in or on the body
obstruction
being clogged or blocked
cancer
a group of more then 200 diseases characterized by uncontrolled and unregulated growth of cells
degeneration
deteriorating of certain parts of the body
genetics
branch of biology that deals with heredity and the study of inheritance
congenital
existing at or dating from birth
healing
the act of process of curing or of restoring to health
acute disease
severe and sudden in onset
illness behaviour
the varying ways individuals respond to physical symptoms, how they monitor internal states, define and interpret symptoms, make attributions, take remedial actions and use various sources of informal and formal care
modifiable risk factors
factors such as behaviour that can be changed to reduce the risk of developing an illness
pathophysiology
patho-suffering physiology-physical function.
how disease functions in the body
-explains the functional changes associated with or resulting from disease or injury
pathology
the science of the cause and effect of diseases
physiology
the branch of biology that deals with the functions and processes of living organism
reparative
repairing the state
etiology
cause of the disease
pathogen
disease causing microorganism
multifactoral
many diseases have a combo of causes
nosocomial
infection acquired in a health care environment
Iatrogenic
disease or injury caused by medical treatment
MRSA
nosocomial passed through facilities. lingers and stays with people. first thing they check when a patient is transferred from one facility to another
idiopathic
no known cause
diagnosis
identifying label for a disease
prognosis
forecasting outcomes
morbidity
disease rate
mortality
death rate
sign
objective, measurable evidence of disease
symptom
subjective evidence of disease. only patient can feel it
local vs systemic
local-broken bone. systemic- blood infection
subacute
between acute and chronic. medically stable but might need medical help
insidious
getting worse over a long period of time
exacerbation
increased irritating of symptoms
remission
symptom free. but still recovering
asymptomatic
absence of symptoms
nursing process
- is a tool or method for organizing and delivering care
- a deliberate intellectual activity whereby the practice of nursing is approached in an orderly systematic manner
- a problem solving approach to client care
- a series of planned steps and actions directed towards meeting the needs and solving problems of people and their significant others
homeostasis
nursing is a way of facilitating this. the tendency of the body to maintain a state of balance and equilibrium while continually changing
homeostatic mechanisms
- self regulating
- compensatory
- tend to be regulated by negative feedback system
negative feedback
sending out signals because your body needs more of something
positive feedback
sending out signals because your body needs less of something
