Infection Flashcards
Invasion of the body with agents that have the potential to cause disease. (get it from each other; on our hands and on our body than touch something) Contagious, Communitaquired or Hospital Acquired.
Infection
Who is the most susceptible of an infection?
Elderly and children
Bacteria Infectious Agents
-staphylococcal, E. coli.
-Aerobic and anaerobic
-Multidrug resistance
-Greatest risk of death
-antibiotic can kill
Virus Infectious Agents
-covid
-DNA or RNA
-Self-limiting; needs a host
-not treatment just to treat the symptoms
-has to run its course
Infection Transmission/Chain of Infection
-Infectious pathogen
-Appropriate reservoir
-Exit route
-Method of transmission
-Portal of entry
-Susceptible host
Fungi Infectious Agents
-Yeast or Molds
-Superficial, intermediate, deep
-can be life threatening and can affect breathing and outcome of patients
are acquired in the community setting, are infectious contagious diseases, can be on surfaces or on the body like hands.
Communicable acquired illness
produce clusters of signs and symptoms that reflect dysfunction of the organs or tissues that the microorganisms have invaded (school, jail) examples of community acquired illness are covid, common colds, flu, pink eye, strep
Community-acquired/HAI Acquired illness
acquired in a healthcare agency; illness a patient gets from the hospital; like C. diff and covid. People go into the hospital without covid but get it while there. If patient suddenly has new symptoms they didn’t have before in hospital admission
Nosocomial/Hospital acquired illness
nonpathogenic or remotely pathogenic microorganisms overwhelm host
Opportunistic/Super infection
measures for reducing the risk of transmitting pathogens. what you do for every patient
Standard precaution
Staph and MRSA infections
Transmission based precautions
-Clean uniforms (remove shoes before going into home so your not spreading illness through your home)
-Hand Hygiene
-Do not wear jewelry(can carry pathogens)/ long nails
-Remain home when ill; advise sick visitors to not come
-Protect immunosuppressed clients from pathogens
Transmission based precaution
Diagnostic test for infections
-WBC: elevated with infection
-Culture and sensitivity: what type of bacteria- blood culture and start broad spectrum antibiotics. To see if there is bacterial growth usually takes 72 hours. To find out what antibiotic medication will be best to kill that infection
-Stool sample: parasites or see if they have C. diff.
-Skin test: swab (fungal infections or if a cut has become infected) or intradermal injection (TB test) (strep test)
-Immunological test: presence of antigens (blood test for varicella virus to see that you have antigens for that virus)
Medical management for infections
-Supportive- Fluid and electrolyte replacement, lots of rest, BRAT diet high protein diet
-Drug administration- give anti retiges meds to take fever down or reduce cramps or muscle cramps
-Debridement/ Removal- clean and scrap all the infection out so it doesn’t spread more
-Immunosuppressed: bone marrow transplant, Neupogen (WBC production), keep away from sick people, give private room or if they have a roommate then they aren’t sick with anything, always doing precautions
-Preventing/controlling the spread of infection (wash hands, keep room clean)- making sure to check the fever is coming down and the lab results
