PATH 1016 Introduction to Pathophysiology, Infectious Processes and
Fever 100% Verified!!
define pathophysiology
- the study of how disease processes affect the function of the body
- explains the functional and biochemical changes that are associated with or a result of
disease or injury
components of the pathophysiology framework
etiology
pathological processes
interventions
components of the pathophysiology framework: etiology
- etiologic factors
- risk factors
components of the pathophysiology framework: pathological processes
- disease/illness
- manifestations and complications
- S&S, body responses
components of the pathophysiology framework: interventions
- diagnostic
- therapeutic
,the role of pathophysiology in nursing care
- Nursing actions require a knowledge base to make informed decisions
- Nurses require a solid foundation in anatomy, physiology, pathology and
pathophysiology to care for clients
- Therapeutic interventions are based on professional assessments of clients...
one cannot accurately assess if one doesn't know what to assess for
chain of infection
infectious agent
reservoir
portal of exit
mode of transmission
portal of entry
susceptible host
chain of infection: infectious agent
Disease-causing organisms or pathogens such as bacteria, fungi, viruses, spores, and
protozoa
Some of these cause acute or short-term infections
Others, such as blood borne pathogens like HIV, Hep B, and Hep C create long-term or
chronic infections
, chain of infection: reservoir
where they live
- people, equipment, water
chain of infection: portal of exit
way out of reservoir
- coughing, sneezing
chain of infection: mode of transmission
Way for pathogen to be transmitted to another reservoir via direct or indirect contact.
- droplet
- airborne (inhalation)
- ingestion
- water
- Blood
- contaminated instruments
chain of infection: portal of entry
way for pathogen to enter new reservoir
-cut, eye
chain of infection: susceptible host
a person likely to get infection-infant, elderly or compromised immune system
