FUNDAMENTALS OF NURSING: INFECTION PREVENTION AND
CONTROL - EXAM 1 NURS125 QUESTIONS WITH ACCURATE ANSWERS
a reservoir correct answer is a place where microorganisms survive, reproduce,
and await transfer to a susceptible host. for microbes to survive they must have a
proper environment with food, water, oxygen, temperature and light conducive
to them. common reservoirs are humans and animals (hosts, asymptomatic
carriers or symptomatic), insects, inanimate objects with organic matter on them
(fomites), food and water.
aerobic bacteria correct answer causes more infections in humans than anaerobic
bacteria. they require oxygen for survival such as staphylococcus aureus.
airboune precautions are used for which diseases? correct answer pathogens less
than 5mcg. measles, varicella (chicken pox), pulmonary or laryngeal tuberculosis.
an infection is correct answer the invasion of susceptible host by pathogens
(micoorganisms) resulting in disease.
anaerobic bacteria correct answer do not require oxygen for survival, and thrive
where little to no free oxygen is available. they usually cause infections deep in
the pleural cavity, in a joint or in a deep sinus tract. an example is bacteroides
fragilis which is part of the normal flora of the colon but causes infection if
displaced into the blood stream or surrounding tissue following surgery or injury.
asepsis correct answer the absence of pathogenic microorganisms.
chlorhexidine (CHG) wash correct answer is required for bathing if there is a risk
for MRSA or other resistant bacteria.
, clostridium pefringens correct answer gas gangrene. thrives on organic matter.
cold temperatures correct answer prevent growth and reproduction of bacteria
this is called bacteriostasis. a temperature or chemical that destroys bacteria is
said to be bactericidal.
colonization correct answer is the presence and growth of microorganisms within
a host but without tissue invasion or damage.
communicable disease correct answer is an infectious disease that can be
transmitted from one person to another.
cough etiquette is very important because correct answer it prevents the spread
of organisms exiting the respiratory tract/respiratory infections such as
mycobacterium tuberculosis, severe acute respiratory syndrome (SARS), and
influenza.
critical items correct answer items that enter sterile tissue. must sterile (free of all
microbes and spores). these include: surgical instruments, cardiac or intravascular
catheters, urinary catheters an implants.
discarding needles correct answer all needles must be discarded into a sharps
container, regardless of the condition of the patient. the needles are disposed of
uncapped.
disinfection correct answer is the process of eliminating many or all microbes with
the exception of bacterial spores, from an inanimate object. there are 2 types:
