Exam 1 Nurs125 Questions With Complete Solutions
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.
