Med-Surg: Chapter 21: Coordinating Care for Patients with Multidrug-Resistant Organism Infectious Disorders Flashcards
What is needed for a pathogen to cause a disease?
- a susceptible host
- mode of transmission
Routes of Transmission
- contact
- airborne
- vehicle
- vector
Who is a susceptible host?
has a weakened immune system or has had a breakdown in the body’s defense mechanism
Contact Transmission
when a person or object comes in contact with a pathogen
- direct: person to person
- in-direct: microorganisms spread from a source to a susceptible host by passive transfer from an inanimate object or fomite, an object or substance capable of carrying an infectious organism
Airborne Transmission
pathogens are carried through the air
Vehicle Transmission
indirect mode of transmission
-a disease carrying agent touches a person’s body or is ingested
Vector Transmission
indirect mode of transmission
-when a vector, an organism that transmits a pathogen, bites or infects a person
Nosocomial Infections
infections that are acquired in the hospital and were ot present on admission
What is a common cause to nosocomial infections?
Multidrug-resistant (MDR) Organisms
Examples of Multidrug-resistant (MDR) Organisms that cause nosocomial infections
- Methicillin-resistant Staphylococcus aureus (MRSA)
- Vancomycin-resistant Enterococci (VRE)
- Clostridioides difficile (C. diff)
- Acinetobacter baumannii
- Carbapenem-resistant Enterobacteriaceae (CRE)
Colonized
the host carries the bacteria without active infection
Best Treatment of MDR organism
prevention- hand washing
Clostridioides and Handwashing
- alcohol-based hand sanitizers do not kill C. diff but just displace spores
- must use soap and water
Patients in healthcare setting who are either colonized or infected with MDR organisms are placed on?
Contact isolation precautions
-placed in private rooms when available or placed in a room with other patients colonized or infected with same organism
Contact Isolation Precautions
reduce patient-to-patient spread of the organism within the hospital
- wearing gowns and gloves on entry to room
- removing gown and gloves prior to exiting
- perform hand hygiene before exiting
