pt care Flashcards
freedom from infection
asepsis
prokaryotic , ubiquitous single celled organism
bacteria
disease causing microorganisms that may be present in human blood
blood-borne pathogens
treatment of disease by chemical agents
chemotherapy
deviations from or interruptions of the normal structure of function of any part , organ or system. prognosis may be know or unknown
diseases
chemicals used to free an environment from pathogenic organisms, to reduce or eliminate infections organisms
disinfectants
organisms whose cells have a true nucleus
eukaryotes
microbial community found in or in a healthy person
flora
an object , such as a book or article of clothing, that is not harmful itself but can serve as an agent of transmission of an infection
fomite
general term used to denote a group of eukaryotic protists , characterized by the absence of chlorophyll and presence of rigid cell wall
fungi
an animal or plant that harbors or nourishes another organism
host
resulting from the activities of physicians
iatrogenic
reduction in numbers of infectious agents, which in turn decreases the probability of infection but does not necessarily reduce it to 0
medical asepsis
pertaining to or originating in the hospital , infection not present before admittance , generally develop after 72 hours
nosocomial
disease producing microorganisms
pathogens
cellular organisms that lack a true nucleus
prokaryotes
alternative or passive host or carrier that harbors pathogenic organisms , without injury to itself , and serves as a source from which other individuals can be infected
reservoir
complete destruction or elimination of all living microorganisms accomplished by physicals methods (dry or moist heat) chemical agents , radiation or mechanical methods
sterilization
procedure used to prevent contamination by microbes and endospores before , during , or after surgery using sterile technique
surgical asepsis
a carrier , especially an animal , that transfers an infective agent from one host to another
vector
a group of infections agents not resolved in the light microscope , the ability to replicate only within living host cells
viruses
volume of air inhaled and exhaled during one respiratory cycle
tidal volume
abnormal rapidity of breathing
tachypnea
rapid heart beat , heart rate great than 100 BPM
tachycardia
presence of air or gas in the pleural cavity
pneumothorax
increased amounts of fluid within the pleural cavity , usually the result of inflammation
pleural effusion
reduction of oxygen supply to the tissue
hypoxia
abnormally low blood pressure
hypotension
difficulty or labored breathing
dyspnea
pertaining to dilation or period of relaxation of the heart , especially of the ventricles
diastolic
describes a product or method that is free of microbiologic organisms
aseptic
examination of a joint using x rags after the injection of opaque contrast material
arthrography
pressure of blood in the thoracic vena cava , near the right atrium of the heart
central venous pressure
indweling catheter retained in the bladder by a ballon inflated with air or fluid
foley catheter
medical condition in which the lungs are not fully inflated
atelectasis
aseptic , free of living microorganisms
sterile
surgical creation of an opening into the trachea through the neck , also used to refer to the opening in the anterior trachea for insertion of a tube to relive upper airway obstruction
tracheostomy
process of depolarization and repolarization of the cardiac membrane
action potential
no evidence of any cardiac neuroconductive activity (full cardiac arrest)
asystole
process whereby cardiac cell membranes spontaneously depolarize at recurrent periods
automaticity
amount of blood ejected from the ventricles each minute, calculated as the product of stroke volume times heart rate
cardiac output
myocardial muscle cells relax
repolarization
quivering contraction of cardiac muscle fibers
fibrillation
myocardial cells are stimulated to contract
depolarization
