unintentional injury |
|
|
Which Evacuation is first? |
Horizontal
|
|
|
3 cardinal rules of radiation protection |
1. minimize the time of exposure from the source 2. maximize distance from the source 3. use appropriate shielding |
|
|
Fall prevention in home |
remove throw rugs, stairs must be well lighted and in good condition, remove clutter, install handrails, clean up spills promptly, raised toilet seat with bars |
|
|

|
Senses involved in Sensory Reception |
5 senses
Kinesthesia - awareness of position of body
Visceral - Internal organs
Sterognosis - perceived solidity of object
Proprioception - input from sensory nerve. terminal in muscles and tendons, joins and vestibular apparatus |
|
|
Reception |
receiving input from the enviroment |
|
|
Perception |
conscious process of selecting, organizing, and interpreting data |
|
|
RAS |
reticular activating system - a network in brain that mediates arousal, selectively allows some nerve impulses to reach the cerebral cortex
|
|
|
Adaptation |
a repeated stimuli no longer gets acted upon` |
|
|
Sensory deprivation |
decreased sensory input of input that is monotonous, unpatterned or meaningless (bedrest, isolation, impaired abilities, CNS Damage) |
|
|
Sensory Overload |
so much sensory stimuli that brain can not respond to or must ignore (hospitalization) |
|
|
Sensory Defecit |
impaired or abscent functioning in one or more of the senses (blindness, hearing impaired, paralysis) |
|
|
Asphyxiation |
suffocation (drowning, choking, blocking airway, gas poisoning) |
|
|
Sentinel event |
unexpected occurance involving death or serious physical or psychological injury or the risk of death or injury |
|
|
Stages of Infection (4)
|
Incubation Period - Pathogen's invasion and appearance of symptoms
Prodromal stage - early, vague signs/symptoms (most infectious stage)
Full stage of illness - localized or systemic symptoms
Convalescent period - recovery period - signs/symptoms disappear |
|
|
Infection
|
Disease state that results from the presence of pathogens (disease producing microorganisms) in or on the body |
|
|
Body's Defense against infection |
Intact Skin
Normal Flora
Inflammatory Response
Immune Response |
|
|
Antigen |
foreign material that causes the problem |
|
|
Antibody |
produced in response to antigen |
|
|
Infection Cycle (6) |
1. Infectious agent 2. reservoir 3. portal of exit 4. means of transmission 5. portal of entry 6. susceptible host |
|
|
Factor Affecting risk for infection |
Integrity of skin/mucous membranes ph Levels of GI, GU, skin Integrity and number of WBC Age, sex, race, hereditary factors Immunizations - natural or acquired Level of fatigue, nutritional, preexisting illness, previous/current treatments, medications Stress levels Use of Invasive/indwelling devices Dangerous practices |
|
|
Asepsis |
a condition free of microorganisms
practicing asepsis prevents the spread of infection |
|
|
Medical Asepsis |
clean technique, keeping area clean, cleaning bedside table, reduces number of pathogens, routine hand washing, non-sterile gloves |
|
|
Surgical Asepsis |
"sterile technique", keeping objects/areas free from microorganisms
|
|
|
Disinfecting |
destroys all pathogens except spores, can be used on skin and equipment |
|
|
Sterilizing |
destroys all pathogens including spores
used on equipment that enters a sterile body part |
|
|
Types of hand hygiene |
plain soap and water, antiseptic handrubs, surgical hand asepsis |
|
|
Why use alcohol based hand rub |
decreases the incidence of dry skin from frequent washing, increased access, faster, increased compliance of staff leading to less nosocomial infection |
|
|
Exogenous
Endogenous
Iatrogenic |
Exogenous - acquired from other people
Endogenous - from microbial life in person
Iatrogenic - infection results from a treatment or diagnostic procedure |
