Safety Unit 2 Flashcards
Heat, redness, pain/tenderness, swelling, possible drainage (bloody, serous, purulent), abscess, cellulitis
Local infection (focal point)
Localized collection of pus
Abscess
Involving cellular and connective tissue
Cellulitis
Fever, malaise, weakness
Systemic ( generalized) infection
Normally 5,000-10,000/mm3
WBC
Increase indicates the presence of disease or injury
WBC
Elevations >15-20mm/h indicates the presence of inflammation
Erythrocytes sedimentation rate (ESR)
Should be obtained before onset of antibiotic therapy
Culture of suspected infectious site
Immediate,short-term, nonspecific response to the side effects of injury
Inflammation
Caused by pathogenic micro organisms and transmitted by direct contact, droplet spread, contaminated articles or through carriers
Communicable disease
Nearly 2 million (5%) hospital patients acquire an infection in the hospital
Nosocomial infection
Most often caused by Staphylococcus aureus
Nosocomial infection
Primary strategy for nosocomial infection control
Standard Precautions (barrier)
Apply to blood, all body fluids, secretions, and ecretions, except sweat
Standard precautions
Use clean nonsterile when touching blood, body fluids, secretions, excretions, contaminated articles
Standard Precautions
Use clean nonsterile gowns to protect skin and prevent soiling of clothing during procedures and patient care activities likely to generate splashes and sprays
Standard Precautions
Private room if patient has poor hygiene habits, contaminates the environment, or can’t assist in maintaining infection control precautions (e.g. Infants, children, altered mental status patient)
Standard Precautions
3 Transmission based precautions
Airborne
Droplet
Contact
Apply to patient with documented or suspected infections with highly transmissible or epidemiological lay important pathogens
Transmission based precautions
Used with pathogens that are transmitted by airborne route
Airborne precautions
Private room with monitored negative air pressure with 6-12 air changes per hour
Airborne precautions
Keep door closed and patient in room
Airborne precautions
Can cohort or place patient with another patient with the same organism, but no other organism
Airborne precautions
Place mask on patient if being transported
Airborne precautions
Used with pathogens transmitted by infectious droplets
Droplet precautions
Involves contact of conjunctiva or mucous membranes of nose or mouth; happens during coughing, sneezing, talking, or during procedures such as suctioning or bronchoscopy
Droplet precautions
Private room or with patient with same infection but no other infection
Droplet precautions
Maintain spatial separation of three feet between infected patient and visitors or other patient
Droplet precautions
Door may remain open
Droplet precautions
Place mask on patient if being transported
Droplet precautions
Needed with patient care activities that require physical skin to skin contact or occurs between two patients, or occurs by contact with contaminated inanimate objects in patient’s environment
Contact precautions
Private room or with patient with. Same infection but no other infection
Contact precautions
Clean, nonsterile gloves when entering room
Contact precautions
Changes gloves after patient contact with fecal material or wound drainage
Contact precautions
Remove gloves before leaving patient’s environment and wash hands with anti microbial agent
Contact precautions
Wear gown when entering room if clothing will have contact with patient, environment surfaces, or if patient is incontinent, has diarrhea, an ileostomy, colostomy, or wound drainage
Contact precautions
Remove gown before leaving room
Contact precautions
Use dedicated equipment or clean and disinfect between patients
Contact precautions

Mumps
- the interval of time required for development.
- the interval between the receipt of infection and the onset of the consequent illness or the first symptoms of the illness.
- the interval between the entrance into a vector of an infectious agent and the time at which the vector is capable of transmitting the infection.
