NUR 210 exam 4
, What is bacteriostatic? - CORRECT ANSWERS-inhibits bacterial growth
what is bactericidal? - CORRECT ANSWERS-kills bacteria
What is a broad spectrum antibiotic? - CORRECT ANSWERS-- able to control a variety
of organisms (gram - or +)
- used when you cannot identify what the organism causing the disease is
- targets many bacteria ("shotgun approach)
when are broad spectrum antibiotics used? - CORRECT ANSWERS-when you do not
know what organism is causing the problem
What are narrow spectrum antibiotics? - CORRECT ANSWERS-- effective against few
organisms (either Gram positive OR Gram negative)
- used when you know which organism is causing the problems and which drug that it is
sensitive to
- targets one organism ("bb gun approach)
When are narrow spectrum antibiotics used? - CORRECT ANSWERS-Whenever the
bacteria causing the disease is known
what does selective toxicity mean? - CORRECT ANSWERS-toxic to a specific cell
(bacteria/microorganism) while sparing other normal cells
is bacterial resistance innate or acquired? - CORRECT ANSWERS-both- can be either
what is meant by bacterial resistance? - CORRECT ANSWERS-ability of an organism
to survive against an antimicrobial or to render the antimicrobial ineffective
What is a super infection? - CORRECT ANSWERS-when an infection arises in addition
to one that is already present; an infection that occurs because of treatment for a
primary infection
what is meant by prophylactic antibiotic use? - CORRECT ANSWERS-antibiotics that
are used to PREVENT infection
what are three surgical procedures that increase the risk for infection? what is often
given with/after the procedures to decrease the risk of infection? - CORRECT
ANSWERS-1. orthopedic
2. cardiac
3. abdominal
prophylactic antibiotics given to reduce the risk of infection
why is there a risk for endocarditis with a patient who has an artificial valve, having
dental surgery? - CORRECT ANSWERS-in the gums are cut bacteria can get into the
bloodstream and travel to the heart and infect the artificial valve
