◉ what is bactericidal? Answer: kills bacteria
◉ What is a broad spectrum antibiotic? Answer: - able to control a

- used when you cannot identify what the organism causing the
disease is
- targets many bacteria ("shotgun approach)
◉ when are broad spectrum antibiotics used? Answer: when you do
not know what organism is causing the problem
◉ What are narrow spectrum antibiotics? Answer: - 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? Answer: Whenever
the bacteria causing the disease is known
, ◉ what does selective toxicity mean? Answer: toxic to a specific cell
(bacteria/microorganism) while sparing other normal cells
◉ is bacterial resistance innate or acquired? Answer: both- can be
either
◉ what is meant by bacterial resistance? Answer: ability of an
organism to survive against an antimicrobial or to render the
antimicrobial ineffective
◉ What is a super infection? Answer: 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? Answer: 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? Answer: 1. orthopedic
2. cardiac
3. abdominal
prophylactic antibiotics given to reduce the risk of infection
