Cards

Term
Antiseptic
Definition
Used to clean living tissue
Term
Disinfectant
Definition
Used to clean inanimant objects
Term
Asepsis
Definition
Absence of infectious organisms
Term
Carrier
Definition
Asymptomatic person or animal
Term
Vector
Definition
Insect carrier
Term
Contamination
Definition
Condition of being dirty or soiled
Term
Endogenous
Definition
Infection comes from our own micro-organisms
Term
Exogenous
Definition
Infections comes from outside micro-organisms
Term
Fomite
Definition
An inanimate object that is capable of harboring a micro-organism
Term
Host
Definition
What an organism lives off of
Term
Infection
Definition
Condition of being invaded by a pathogen
Term
Standard Precautions
Definition
Protect patients from medical staff and vice versa
Term
Virulence
Definition
Strength of a micro-organism
Term
Medical Asepsis
Definition
Clean techniques used to remove all grosss contamination (PO meds)
Term
Surgical Asepsis
Definition
Sterile technique for material that will go into the body (IV, dressing changes)
Term
Bacteriology
Definition
Study of bacteria
Term
Aerobic
Definition
absence of infectious organisms
Term
Anaerobic
Definition
Only able to grow in the absence of oxygen
Term
Culture
Definition
Infected body secretions that are transferred to a medium where micro-organisms can grow
Term
Sensitivity
Definition
Testing that determines which antibiotic are effective against the organism
Term
Resistant Organisms
Definition
Caused by improper administration of abx, common resistant organisms; MRSA, VRE
Term
Spores
Definition
Form when conditions are not suitable for growth. Form hard protein shell, not active, waiting until conditions improve. They remain dormant. Resistant to heat and disinfectants. High heat, greater than 225 F kills them.
Term
Capsules
Definition
Formed around the cell wall; form when the environment is unfavorable. Still active, can possibly make abx ineffective
Term
Common Bacterial Organisms
Definition
Streptococcus aureus, B-hemolytic group A streptococci, B-hemolytic grou B streptococci, Escherichia coli
Term
Viology
Definition
Branch of science and medicine that deals with the study of viruses
Term
Viruses
Definition
Smallest known agents that cause disease, not a complete cell, obligate intracellular parasites, consists of protein coat around a nucleic acid core
Term
Viruses are identified by
Definition
Flourescent technique, electron microscope, tissue cultures
Term
Viruses can be controlled by
Definition
Quarantine, good hygiene, changes in lifestyle, elimination of the vetor, or immunizations of the population
Term
Mycology
Definition
Study of fungi
Term
Mycoses
Definition
Fungal infection; vaginal candidiasis, tinea pedis, dermatomycosis, candida albicans
Term
Pt's receiving abx therapy have increased risk of
Definition
Fungal infection and yeast infection related to opportunist overgrowth of normal body flora
Term
Parasitology
Definition
Study of plants and animals that live as parasites; protozoa and helminthic acquisition. Parasites commonly aquired from outside sources, i.e pets
Term
Protozoa
Definition
Cause malaria, amebic dysentery, african sleeping sickness
Term
Helminths
Definition
Parasitic worms or flukes. Most common in North America is pin worms
Term
Susceptibility
Definition
Determined by amount of resistance to a pathogen, factors are age, point of entry, nutritional status, stress, fatigue, medical treatment, virulence, invasiveness
Term
First line defense mechanisms
Definition
Mucous membranes, skin, cilia, normal flora
Term
Second line defense mechanisms
Definition
Phagocytes, lysozymes, digestive systems
Term
Third line defense mechanisms
Definition
Humoral immune response against pathogen, antibodies produced by lymphocytes to bind with, inactivate specific micro-organisms
Term
Healthcare Associated Infections
Definition
Hospital or healthcare setting acquired, at least 72 hours after admission. Most common cause, neglect of aseptic techniques, also shortage of staff, types of health workers, treatments and medications, overcrowding of hospitals
Term
Types of pt's most vulnerable to HAI
Definition
Deficient immune response, steroids, anti-cancer, anti-lymphocyte serum, radiation, diabetics, cancers, paralyzed
Term
Incubation Period
Definition
Onset of disease
Term
Prodromal Period
Definition
Big signs and symptoms
Term
Full State of Illness
Definition
Obviously sick
Term
Convalescent Period
Definition
Recovery stage
Term
Nursing Implications for Pt Susceptible to Infection
Definition
Knowledge of pt's dx, application of scientific principles, avoid contributing to HAI, demonstrate proper precautions, pt teaching, follow hospital infection control policies, knowledge of abx treatment
