communication
to convey info accurately, can be verbal or nonverbal
verbal communication
tone, pitch and volume
nonverbal communication
eye contact, touch, appearance, listening skills, attitude
assertive
calm, firm expression of feelings/opinions
aggressive
undesirable behavior characterized by anger or hostility
personal space
the distance around someone that is considered to be private
social space
4-12 feet
personal space is usually
18”-4’
intimate space
up to 18”
challenges to communication
culture, age (peds, geriatrics), language barriers, gender
ethnocentrism
the belief that ones own cultural values are superior to others
aphasia or dysphasia
an abnormal neurological condition in which language function is defective or absent because of an injury to certain areas of the brain
altered states of consciousness
drowsy, unconscious, comatose
drowsy
will respond to stimulus
unconscious
won’t respond to stimulus
comatose
unconscious for 24 hours
the grieving process
denial, anger, bargaining, depression, acceptance
radiographs belong to the institution, not the patient
the patient owns the results of the study
radiographs must be kept for a minimum of
5-7 years
sentinel event
error that happens in health care that causes serious injury or death to patient
proper body alignment, movement, and balance are necessary to
prevent injury to either the health care worker or patient
base of support
portion of body in contact with the ground
center of gravity
point around which body weight is balanced
line of gravity
from combined center of gravity through base of support
ambulatory patient
can walk and move with little to no assistance
immobile patient
cannot walk, move, or assist in transfer
paraplegia
paralysis from the waist down
hemiplegia
paralysis on one side of the body
quadriplegia
paralysis from the neck down
orthostatic hypotension
feeling of lightheadedness upon standing after being recumbent (due to sudden drop in blood pressure)
syncope
sensation of feeling faint
ataxia
uncoordinated movement
fall risk
person w/increased likelihood of falling
stretcher to table or bed transfer
all wheels locked, assistance from others,, preferred two people on each side with slider board or draw sheets
wheelchair to table/bed transfer
wheelchair locked placed parallel to table with “strong” leg closest to table, tech standing with legs between footrests to support and lift into upright position (squat, lift w/legs)
transfer from wheelchair to stool
should only be done with patients who are able to assist
basic log roll
patients hands across chest, two people on each side of patient and one maintaining proper head/neck alignment, sheets wrapped tightly around patient and rolled. reinforce with sheets/pillows
microorganisms
living organisms too small to be seen with the naked eye
pathogens
microorganisms that cause infection and disease (bacteria, virus, protozoa, fungi, prions)
bacteria
single celled organisms with a cell wall which can grow independently without a host, classified by shape (spherical, rod-shaped, spiral)
spherical bacteria
cocci - staphylcoccus (staph)
rod shaped bacteria
bacilli - tubercle bacili (tb)
spiral shaped bacteria
spirilla - syphillis
bacterial spores
endospores (exospores), “waxy coat” which protects the bacteria within
tuberculosis
bacterial disease airborne spread, formerly known as consumption
antibiotic resistant bacterial strains
MRSA, VRE, C Dif
Virion
fully developed viral particle
virus
sub-cellular organisms with no cell wall
syndrome
a collection of symptoms
blood borne pathogens are most commonly contracted by
IDU’s (intravenous drug users)
in 1991 OSHA mandated that healthcare workers be provided with
the Hep B immunization
fungi single celled
yeast - bud cells
fungi long strands
mold - many cells
protozoa
complex, single celled animals classified by motility
changing shape
psuedopods
cilia
little hairs
flagella
whip like tail
prions
smallest of ll known pathogen, do not have dan/rna
cycle of infection
infectious agent, reservoir of infection, portal or exit, mode of transmission, portal of entry, susceptible host
infectious agent
pathogen
reservoir of infection
where pathogens can thrive in numbers to pose a threat
portal of exit
how pathogens leave the infected hosts body
mode of transmission
how pathogen travels from one body to another
portal of entry
how pathogen enters another persons body
susceptible host
person who can be infected by pathogen
direct contact transmission
skin to skin, mouth to mouth, mucous membrane to membrane, sexual contact
fomite
an indirect mode of transmission, an inanimate object
vector
indirect, insect or tick, an indirect mode of transmission
vehicle
a medium for transport such as food, water, blood, indirect
droplet
indirect. cough, sneeze, travel short distances, contacts membranes of new person
airborne
indirect, dust and spores, can stay in the air a long time, very, very small
portals of entry/exit
mucous membranes/eyes, nose, mouth, skin, open sores, respiratory systems, airborne, go systems, ingestion, fecal. urinary system, urine, circulatory system, wounds, reproductive system, semen, vaginal
immune system
bodys defense against disease causing microorganisms (pathogens), foreign tissues, and body own cells that have turned cancerous
nonspecific immunity (innate immunity)
generalized protection such as tears, mucous secretion, phagocytosis, inflammatory response
the 4 hallmarks of inflammation
calor, dolor, rubor, edema
calor
heat due to increased blood flow
dolor
pain
rubor
redness
edema
exudate from blood stream
specific immunity (adaptive immunity)
requires a previous exposure to the pathogen; first exposure = sick, second = not sick
specific immunity types
natural, active, passive
natural immunity
just happens as a result of living
active immunity
individual immune system response to pathogen (measles - only get once)
passive immunity
mothers milk, antibodies from mom to infant
artificial immunity
man made (vaccinations)
antibodies
destroys and/or inactivates antigens
antigens
foreign substance in body
complement protiens
inactive enzymes normally present in blood, when activated kill foreign cells by dissolving
combining sites
concave areas on antibodies that fir the precise size and shape of a marker molecule
marker molecules
fragments of dna that make an antigen unique
antibodies
bind with antigens, :lock and key:
