infection control, safety and quality control

QuestionAnswer
name the 4 conditions required for bacterial growth moisture, temperature, oxygen and light
moisture for bacteria to grow can be found in skin, mucous membranes, wet dressings, wounds, dirty instruments and needles
optimum temp for bacteria to grow 98.6F (37C) body temp
temp that can kill bacteria 107F (42C)
aerobic bacteria require oxygen to live
anaerobic bacteria can survive without oxygen
what kind of light does bacteria require to grow darkness favours the bacteria, they will die if exposed to direct sunlight or ultraviolet light
name the natural barriers the body has to break the chain of infection skin, mucous membranes, GI tract, lymphoid and blood systems
what is the largest natural barrier to infection & what/how does it work intact skin, low pH factor inhibits bacterial action.
how do mucous membranes help repel bacteria throat - coughing, mucous helps flush. nose - sneeze. GI - acid.
list some of the places mucous membranes are found respiratory, digestive, reproductive, urinary tract
what constitutes a reservoir or "source" individuals who are ill with a disease and human carriers of disease who are unaware they have the disease but can still spread it.
portal of exit, or means of escape from the reservoir respiratory tract secretions, intestinal waste products, reproductive tract secretions, blood and blood products and across the placental barrier
means of transmission for the pathogen to pass directly from the reservoir to the new host milk or water
portal of entry or means of entry respiratory tract, skin an mucous membranes, reproductive and urinary tracts, blood, and across the placental barrier, for the pathogen to enter into the new host
susceptible host elderly patient, immunocompromised, poor nutrition, lack of sleep, very young
single best step to prevent the spread of infection hand washing
asepsis medically it refers to the destruction of organisms after they leave the body.
asepsis techniques hand washing, disposable equipment, wearing gloves
surgical asepsis techniques surgical hand washing, sterile gloves and equipment
isolation procedures & some equipment protect both the patient and the health care worker. PPE equipment such as eye shields, gowns, gloves, masks
strict isolation when patients have a highly contagious disease such as bacterial pneumonia, smallpox, diphtheria or chicken pox. Private closed room.
enteric isolation for patients who have intestinal infections such as salmonella, shigella and hep A & E. Must wear a gown and gloves, all waste material is disposed of in special containers in the room.
contact isolation used for patients who have diseases such as influenza. Direct contact transmission. Masks, gowns and gloves.
respiratory isolation used for patients who have diseases that can be spread by droplet infection such as haemophilus influenza, meningococcal meningitis, tuberculosis or measles. Private room with closed doors. Masks
wound or skin isolation used for patients who have an open wound, sore or skin infection. Gown and gloves
reverse isolation or protective isolation used to protect noninfectious patients who may be susceptible to disease or infection. Ex. immunodeficiency diseases, tissue transplants, burns or chemotherapy & newborn nurseries. Anything brought in must be sterile. Masks, gowns and gloves.
standard precautions apply to what bodily fluids blood, non intact skin - tissue specimen, all body fluids except sweat.
standard precautions equipment hand washing and the use of gloves, masks & gowns, eye protection
