Asepsis and infection control Flashcards
Freedom from and prevention of disease causing contamination.
Asepsis
Group of microorganisms that live in or on the body but do not cause disease.
Normal flora
Nonspecific immune system that provides immediate defense against foreign antigens.
Innate immunity
Acquired or specific immunity that provides long-term immunity when the body is exposed to an antigen.
Adaptive immunity
What are the two types of adaptive immunity?
Humoral and cellular
A defense system that involves WBCs that produce antibodies in response to antigens or pathogens circulating in the lymph and blood.
Humoral immunity
Involves defense by WBCs against any microorganisms that the body does not recognize as its own.
Cellular immunity
This transmission occurs when microorganisms are dispersed by air currents and inhaled or deposited on the skin of a susceptible host.
Airborne transmission
This transmission occurs when mucous membranes of the respiratory tract are exposed to the secretions of an infected individual.
Droplet transmission
Nonsocomial infections that are acquired while a patient is receiving treatment in a health care facility, clinic, or primary care office.
Health-care associated infections (HAIs)
Clean technique. Procedures include hand-washing, wearing gloves, gowning, and disinfecting.
Medical asepsis
Sterile technique used to prevent the introduction of microorganisms from the environment to the patient. used for surgical procedures, invasive procedures, procedures that break the skin, procedures that invade the bloodstream.
Surgical asepsis
Is the process used to destroy all microorganisms including their spores.
Sterilization
The removal of pathogenic microorganisms from inanimate objects, Removes all except spores.
Disinfection
Applying PPE steps include: HGMEG
Hands (wash them)
Gown
Mask
Eyewear
Gloves
Removing PPE steps include: GGHEMH
Gloves
Gown
Hands (perform hand hygiene)

These precautions are used when known or suspected contagious diseases can be transmitted through large droplets suspended in the air.
Droplet precautions
These diseases have which type of precautions: pharyngeal diphtheria, mumps, rubella, pertussis, streptococcal pharyngitis, scarlet fever, pneumonias, pneumonic plague, influenza, meningococcal sepsis.
Droplet precautions
These precautions are used when known or suspected contagious diseases can be transmitted by means of small droplets or particles that can be suspended in the air for prolonged periods.
Airborne precautions
Which type of precaution is needed for these diseases: Varicella zoster, measles, mycobacterium tuberculosis, COVID 19
Airborne precautions
These precautions are used when a known or suspected contagious disease may be present.
Contact precautions
