Document Summary
Week 1: critical thinking, nursing process, and infectious diseases: explain the relationship between the chain of infection and the transmission of infection. In order for infection to occur all elements of the chain must be present. Transmission is part of this chain and can be direct, indirect, via droplet, airborne, via vehicles and via a vector. Chain of infection: the steps required for an illness to pass from one person to another. Where germs live (reservoir): people, animals/pets (dogs, cats, reptiles), wild animals, food, soil, How germs get out (portal of exit): mouth (vomit, saliva), cuts in the skin (blood), during diapering and toileting stool. Germs get around (mode of transmission): contact (hands, toys, sand), droplets (when you speak, sneeze or cough) How germs get in (portal of entry): mouth, cuts in the skin, eyes. Next sick person (susceptible host): babies, children, elderly, people with a weakened immune system, unimmunized people, anyone.
