lymphatic system pt. 1
what does the lymphatic system do
balances fluid, absorbs fat, immune defense, works with the circulatory system
what's lymphedema
a blocked lymph vessel
what criteria do you need to meet for it to be considered an HAI?
2 days after getting to the hospital
3 days after leaving the hospital
30 days after a surgery
how can you prevent the spread?
wash hands, ppe, isolation procedures, medical vs. surgical asepsis, porper removal of sharp things/contaminated items
what does sterile mean? sterilization? contamination?
sterile: free from all microbes
sterilization: process of removing microbes
contamination: exposure to pathogen
what are/what do your tonsils do?
form a ring around your throat to protect you
what's lymph?
clear watery liquid formed between cells (90% goes back into the capillaries)
stages of infection?
incubation (exposure): initial entry pathogen, no s&s (signs and symptoms)
prodromal: pathogen multiples, s&s start
illness: s&s very severe and obvious
decline: pathogens start to die, s&s decline
convalescence: back to normal
what's an infection? types?
infection: invasion of pathogens in the body
- local: part of the body
- systemic: whole body
what's an N-95 mask? purpose?
special masks for bad diseases (need to be fitted for them)
what does the spleen do? what quadrant?
LUQ
white pulp: filters blood
red pulp: stores rbc
what does the thymus gland do?
t-lymphocytes go to thymus for school on how to recognize bad microbes
3 most common causes for HAI's?
- central line-associated bloodstream infection (CLABSI)
- catheter-associated urinary tract infection (CAUTI)
- surgical site infection (SSI)
cleaning: reducing number of microbes, removes visible dirty-ness
disinfection: destroys all pathogens, spores not destroyed, chemical disinfectants are used to clean reusable items
sterilization: destroys nonpathogens and pathogens including spores at very high temps
what's asepsis? types?
destroying/eliminating potential pathogens
medical/clean: destroys pathogens, prevent spread
surgical/sterile: destroys all pathogens, get rid of ALL microbes
where does lymph come from?
capillaries leak out fluid, and then go into our lymph nodes (this is where it's offically called lymph), which will return the fluid back into the capillaries in the chest via ducts
what does peter's patch/your appendix do?
filters bacteria/prevents bacteria in intestines from escaping
what are some signs & symptoms?
signs: high temp, change in vitals, antibiotics in blood serum
symptoms: nausea, vomiting, pain, loss of appetite, headache, weakness
what is considered an outbreak?
- higher-than-normal rate
- single cause for epidemic of a disease
- suspected event invoicing microbial food and water
what's a transmission based precaution? types?
when someone has something you really don't wanna get
- airbourne
- droplet (coughing/sneezing)
- contact (touch)
what are lymph capillaries lined with? what moves the lymph?
endothelial cells
valves
how does lymph move? path it takes?
skeletal muscles move it
vessels → nodes → ducts in chest (right lymphatic/thoracic)
what's a superbug?
resistant to many drugs including prescription drugs, weakens immune system
what are the 3 types of superbugs?
clostridium difficile infection (CDI)
- inflammation in intestine and diarrhea
methicillin resistant staphylococcus aureus (MRSA)
- common in immunocompromised patients
vancomycin resistant enterococci (VRE)
- bacteria in intestinal tract
proper order from donning/doffing?
donning: wash hands → gown → mask → eyes → gloves
doffing: gloves → gown → eyes → mask → wash hands
