Asepsis and Infection control for Exam 2
What are infective agents?
How do you classify bacteria?
What is a prion and what is one example?
A small proteinaceous infectious disease-causing agent that is believed to be the smallest infectious particle. Contains no genetic material
No treatment available
Creutzfelt Jakob Disease (Mad Cow Disease)
What are the components of the Infection Cycle?
Portal of Exit
Portal of Entry
What are the modes of transmission?
: Direct, Indirect, and Fomite
: west nile virus, Lymes disease
What are common portals of exit and entry?
breaks in the skin
blood and tissue
What are some determining factors for a susceptible host?
: acquired or natural
general health status
How do you tell the difference between a local and systemic infection?
: edema, erythema, exudate
: febrile, fatigue, anorexia, lynph node enlargement, inflammatory response throughout the body
What are the three duration periods of an infection?
: fast onset and short infection resulting in healing
: lasts longer than 6 months, such as osteomyelitis
: Takes time to show s/s such as Mad Cow Disease
What are the stages of infection?
: time of exposure until time of first s/s
: most infectious stage, general and vague s/s
Stage of Illness
: s/s of illness
What are the three lines of defense against illness?
Primary line of defense
: normal flora, mucus membranes, pH balance, anatomical features that limit entry
Secondary line of defense
: inflammatory response
Third line of defense
: activation of immune responses against specific, recognized invaders
: B lymphocytes-->allergies
: T lymphocytes
What is a normal WBC?
What are some factors that support host defense?
rest and exercise
What are some risk factors for infection?
breaks in the first line of defense
illness or injury
multiple sexual partners
nursing and medical procedures
What do the ESR and C-reactive protein labs test for?
Erythrocyte sedimentation rate and c-reactive protein labs are markers to tell if the inflammation response is occuring
What are the lab values for a WBC with differential?
elevated neutrophils are a sign of infection
elevated eosinophils are a sign of allergic response
What is the difference between medical and surgical asepsis?
: clean technique
: sterile technique
Who is responsible for creating infection control precautions?
OSHA regulations for universal precautions
current CDC guidelines
What is the Tier One CDC Guidelines?
-follow hand hygiene techniques
-wear clean nonsterile gloves
-wear PPE equipment when necessary
-Avoid recapping needles
-handle soiled patient care equipment carefully
-Review room assignments
What are the tier two CDC guidelines?
-used for patients with known or suspected to be infected or colonized with infectious agents
-use in addition to standard precautions
*Contact Precautions (most common)
What is protective isolation?
It protects an immuno-compromised patient from organisms brought in by healthcare workers and visitors
What is an HAI?
A hospital acquired illness
often a UTI or pneumonia
