Complex and larger organisms that contain a nucleus and organelles fall into this category.
eukaryote
This trains the immune system to recognize and combat pathogens and removes the susceptibility of the host.
vaccination
A set of specific practices and procedures, with the goal of minimizing contamination by pathogens and preventing HAIs.
asepsis
Malaria is caused by this type of pathogen.
protozoa
MRSA, VRE, MDR-TB are ___________________ bacteria.
antibiotic resistant
Tiny animal-like organisms found in contaminated water.
protozoa
Microorganisms that do not cause disease.
non-pathogens
The type of bacteria which often infects humans via the animal the it inhabits, such as fleas, lice, and ticks.
rickettsiae
Ringworm is caused by this type of pathogen.
fungi
In order to minimize the spread of diseases, the CDC recommends this approach to infection control: treat all human blood and certain human body fluids as if they were known to be infectious.
standard precautions
Solutions applied directly to the skin that prevent or inhibit the growth of pathogens.
antiseptics
An infection acquired in a healthcare facility that is unrelated to the patient's illness.
HAI or nosocomial infection
This type of precaution may be required for patients who have highly infectious diseases which are spread by a cough or sneeze.
droplet precautions
Considered the clean portion of PPE.
inside, back
The sequence (order) used for donning PPE
gown, mask, goggles, gloves
How pathogens move. (4th link in chain of infection)
mode of transmission
______________ asepsis is referred to as the " sterile technique". It considers everything not sterile as contaminated.
Surgical
_______________ are used to kill bacteria.
antibiotics
5 factors that influence microbial growth.
temp, pH, food, moisture, oxygen
Considered the contaminated portion of PPE.
outside, front
The route pathogens take to leave the reservoir. (3rd link in chain of infection)
portal of exit
Rocky mountain spotted fever is caused by this type of pathogen.
rickettsiae
This type of precaution may be required for patients who have skin or wound infections which could be transmitted by direct or indirect contact.
contact precautions
The first link in the chain of infection.
infectious agent (pathogen)
The use of microorganisms as weapons.
bioterrorism
Single-celled organisms which are classified according to their shape and arrangement.
bacteria
Streptococcus (strep throat) is caused by this type of pathogen.
bacteria
How pathogens get in. (5th link in chain of infection)
portal of entry
The nation’s most widely used HAI tracking system.
National Healthcare Safety Network (NHSN)
Non-living materials which house microorganisms.
fomites
Specialized clothing or equipment worn by an employee for protection against infectious materials.
personal protective equipment (PPE)
__________________ microbes live only in the presence of oxygen.
Aerobic
Complete removal of pathogens. The most effective way to destroy all microorganisms and their spores.
sterilization
Microorganisms that cause disease.
pathogens
Strong chemicals used to destroy pathogens on objects, not skin.
disinfectants
The science that studies living organisms that cannot be seen with the naked eye.
microbiology
The MOST important practice for aseptic technique.
hand hygiene
The sequence (order) used for doffing PPE
gloves, goggles, gown, mask
Someone who is capable of being infected. (6th link in chain of infection)
susceptible host
Medical asepsis is referred to as the " _______________ technique".
clean
Herpes, Hepatitis B, and AIDS are caused by this type of pathogen.
virus
__________________ microbes grow best in the absence of oxygen.
Anaerobic
The place where pathogens live. (2nd link in chain of infection)
reservoir
The smallest of all microorganisms.
virus
5 common signs and symptoms of a local infection.
redness, swelling, tenderness, warmth, drainage
Plant-like organisms such as yeast or mold.
fungi
Single-celled organisms with NO nucleus (the DNA is found in the cytoplasm) fall into this category.
prokaryote
This type of precaution may be required for patients infected with microorganisms that remain in the air for long periods of time. Must wear a (HEPA) filter or mask.
airborne precautions
