1004 Final exam Flashcards
What is the history of Nursing?
- 1811 Sydney Hospital opened
- 1868 Lucy Osborne established schools of nursing
- Mid 1990’s Hospital based training
- Since 1990 education for RN has been placed in the tertiary sector
- 20 years to fight for nursing to become a proffession
What is nursing?
= the ability of nursing is to respond to peoples need for nursing within the rapidly changing environment in which health care depends on.
- use of clinical judgement
- to promote, prevent and protect disease and illness
- advocate for patient rights
Infection control:
What is an infection?
= a disease or state that results from the presence of pathogens in or on the body.
What is a pathogen?
= a disease producing microorganism
What is a HAI?
= Hospital associated infection
= any infection that develops as a result of healthcare from which the patients was not suffering prior to admission.
- Major growing issues with the most common as a UTI
- most are preventable - under the care of the nurse
Iatrogenic infection ?
= infections that occur as a result of health care intervention
Colonisation
= sustained presence of replicating infectious agents on or in the body without the production of an immune response or disease and is a potential source of transmission.
what are the implications of HAIs?
- longer time in hospital = longer time away from family
- burden to healthcare system = financially
- impact on social, physical, mental health of pt
- using bed for longer = affecting hospital
- increased recovery - more pain, discomfort and antibiotics
What is the chain of infection transmission?
= an infection occurs as a result of a cycle process consisting of 6 components
- Causative agent (infection agents)
- reservoirs
- Portal of exit
- Means of transmission
- Portal of entry
- susceptible host
Chain of infection transmission:
1. causative agent (infection agents)
Bacteria - most common for causing HAIs
- shape - round, rod-shaped , spiral
- reaction to gram stain - pos and neg
- need for oxygen - aerobic and anaerobic
Virus - smallest of all microorganisms
- requires a living host cell to replicate
Fungi - plant like organism
- moulds and yeast
Protozoa - microscopic
- free living or parasitic in nature
Chain of infection transmission:
2. Reservoir
= habitat in which the agent normally lives, grows and multiplies including:
- other humans
- animals
- soil
- water
- intimate objects
- milk
Chain of infection transmission:
3. Portal of exit
= the way the pathogen leaves the body
- respiratory tract
- gastrointestinal tract
- genitourinary tract
- skin breaks
- blood and other tissues
Chain of infection transmission:
4. Means of transmission
Contact
- direct, indirect - contact with contamination - vectors (carries)
Airbone
- small particle areoles - dust, talking
Droplets
- coughing, sneezing, talking
Chain of infection transmission:
5. Portal of entry
= point where organism enters new host
- urinary tract
- respiratory tract
- skin
- gastrointestinal tract
Chain of infection transmission:
6. Susceptible host
= whether a person acquires an infection or not depends on their susceptibility to an infectious agent
- age, nutritional status
- stress
- hereditary conditions
- disease process
How does the body defend itself against infection?
1st line of defence
- mechanical barriers - skin, mucous membranes, cillia
- body secretions - saliva, sweat, tears, gastric juices,
bile, mucus
- Normal flora
- lymphoid tissue
2nd line of defence
- inflammatory response
3rd line of defence
- immune response (T and B cells )
What are the stages of an infectious disease?
- Incubation period = interval between entry of pathogen into body and appearance of first symptoms
- Prodromal stage = interval from onset of non specific signs to mores specific symptoms
- illness stage = interval where patient manifest mores specific signs and symptoms to the type of infection.
- Convalescence = interval where acute symptoms of infection disappear
- length of recovery depends on severity of infection and patient
Ways to reduce spread of infection?
standard precautions: - hand hygiene - use of PPE - safe use and disposals of sharps - routine environment cleaning - respiratory hygiene etc
Who regulates the profession of nursing?
= CO- REGULATION in australia
- government
- ourselves as nurses
- registration
- codes and guidlines
- complaints and notifications
- accreditation
