NURS 255 Exam 3 Flashcards
(49 cards)
6 Links (Infectious agent: What is it?)
- Can be flora
- Normal
- Transient
- Resident (from the skin)
- Pathogens
6 Links (Reservoir: What is it?)
- Living (people or plants)
- Carriers
- Nonliving (Desks, bedrails)
6 Links (Portal of exit: What is it?)
- The way in which the infection leaves the previous host
6 Links (Mode of Transmission: What is it?)
- Contact
- Direct touching
- Indirect
- Droplet
- Airborne
6 Links (Portal of entry: What is it?)
- Body openings
- Bites from a vector
6 Links (Susceptible host: What is it?)
- Inadequate defence mechanisms
- Factors like sexual partners, immunosuppression, smoking, chemotherapy can increase susceptibility
What are the 5 Stages of an Infection?
- Incubation (No symptoms)
- Prodromal (No symptoms but can spread)
- Illness (Symptoms)
- Decline (Symptoms improve)
- Convalesce (Symptoms disappear)
Classifications of infections by Location (2 types)
- Local infections
- Systemic
- Bacteremia
- Septicaemia (In the blood)
Classifications of Infections by Duration (3 types)
- Acute
- Chronic
- Latent (Lies dorment)
Primary Defences (What are they?)
- Intact skin
- Mucous membranes
- Tears
- Normal flora in GI tract
- Normal Flora in urinary tract and vagina
Secondary Defences (What are they?)
- Phagocytosis
- Complement cascade
- Inflammation
- Fever
Tertiary Defences (What are they?)
- Active immunity
- Passive immunity
- Specific immunity
- Cellular immunity (Cell mediated)
- Humoral immunity (Antibody mediated)
What factors place someone at risk for infection?
- Age (immune system development)
- Breaks in skin
- Illness/injury, Chronic disease
- Smoking, substance abuse
- Sex partners
- Medications (Some)
What is Medical Asepsis?
A state of cleanliness that decreases the potential for spread of infections
What can you do to maintain a clean environment?
- Clean spills and dirty surfaces
- Disinfect
- Remove clutter
- Consider supplies brought to the client room as contaminated
- consider items from the clients home contaminated
Why are Multidrug-resistant pathogens of concern for healthcare providers?
- Antimicrobial resistance is one of the most difficult challenges to treat patients with severe infections
- There are limited options to treat MDRO’s
- They are associated with serious illness, increased mortality, and increased hospital lengths of stay.
Why are patients in their homes at less risk for infection than those in hospital?
- They share the same potential pathogens and antibodies
- There is limited exposure to others with illness
What is the nurses responsibility as it relates to infection prevention?
- The nurse is responsible for monitoring that patients, other healthcare workers, and visitors are responsible and adhere to best prevention practices.
What role does a nurse play in preventing biological epidemics ?
- The nurse should be able to recognize an outbreak based on its grouping of symptoms
- Notify a safety officer
- Use appropriate level of standard precautions
- Prepare clients for a disease outbreak
What are the two types of Healthcare related infections (2 types)
- HAI’s (infections caused by healthcare given to an individual)
- Nosocomial infection (hospital acquired infection)
What does the CDC do?
- Responds to new and emerging health threats worldwide, detects and tracks disease, and provides health information to prevent and control the spread of diseases.
What does the CDC aim to reduce specifically? (7 types of infections)
- Central line associated blood stream infection
- Surgical site infection
- Catheter-associated urinary tract infection
- Methicillin-resistant staphlycoccus aureus infection
- Ventilator associated pneumonia
- Multidrug resistant organisms ‘
- Clostridium defficile infection and hospitalization
Agency for Healthcare Research and Quality (What do they do?)
- To provide scientific evidence to make healthcare safer and make health information tools and resources available for both healthcare providers and consumers
The Joint commission (What do they stand for?)
- Quality oversight agency
- Provides standards for what healthcare organizations use do to minimize risks
