portal of exit, mode of transmission, and then back to portal of entry, and it
continues in a cycle.
Reservoir - ANSWER: A place where microorganisms survive, multiply, and await
transfer to a susceptible host
Transmission Through Direct Contact - ANSWER: Person to person
Person to source
Transmission Through Indirect Contact - ANSWER: Person to inanimate object

Four Stages of Infection - ANSWER: 1. Incubation Period
2. Prodromal Stage

interval between onset of nonspecific symptoms to more specific symptoms. You

the infection is in one spot. There is no fever (fever means it's systemic)
Systemic Infection - ANSWER: An infection that affects the entire body, it can be
fatal if not detected or untreated.
Normal Flora - ANSWER: Microorganisms that reside normally in our body. They
help resist infection by releasing antibacterial substances and inhibiting
multiplication of pathogenic microorganisms
, Body Defense Mechanisms Against Infection - ANSWER: Normal flora, intact skin,
mucus membranes, cilli in respiratory system, fever, inflammation, vascular and
cellular response, and tissue repair
Inflammation - ANSWER: Vascular and cellular response leads to blood gathering in
the area, exudates appear (serous=clear, sanguineous=red, purulent=white/yellow),
tissue repair
Healthcare-Associated Infection (HAI) - ANSWER: Also called nosocomial infection,
results from delivery of health services in a health care facility. Can occur as the
result of invasive procedures, antibiotic administration, the presence of multidrug-

Patients at Risk for HAI - ANSWER: If the patient has multiple illnesses, older adults,
poorly nourished, lowered resistance to infection critical/chronic illness, invasive
treatment devices, many procedures, and young children
Major Sites for HAI Infections - ANSWER: Surgical or traumatic wounds, urinary and
respiratory tracts, bloodstream, any skin openings, and breaks in mucus membranes
Iatrogenic HAI - ANSWER: HAI from a diagnostic/therapeutic procedure
Ex) a dialysis patient repeatedly coming to the hospital, a patient with a catheter
inserted poorly or cleaned poorly
Exogenous - ANSWER: From microorganisms found outside the individual
Endogenous - ANSWER: Occurs when part of the client's flora becomes altered and
an overgrowth results
Ex) c.diff
Standard Precautions - ANSWER: Prevent and control infection and its spread.
Medical Asepsis - ANSWER: Controlling pathogen, hand hygiene, common on home,
ECF, assisted living
Sterile Asepsis - ANSWER: Killing or eliminating the pathogen, scrub (surgical), PPE
sterile handling, common in hospitals
Principles of Surgical Asepsis - ANSWER: 1. A sterile object only remains sterile if
touched by another sterile object
2. Only sterile objects may be placed in a sterile field
3. A sterile object or field out of range of vision or an object held below a persons
waist is contaminated
4. A sterile object or field becomes contaminated by prolonged exposure to air
5. When a sterile surface comes in contact with a wet, contaminated surface, the
sterile object or field becomes contaminated by capillary action
6. Fluid flows the in the direction of gravity
