EXAM 3 Anti-Infective Flashcards
antibacterial
Active against bacteria
anti-infective
Treating infections caused by bacteria
Bacteriostatic
Slow or retard multiplications of bacteria
Bacteriocidal
Destroys and kills bacteria
broad spectrum agent
- Treats multiple types of bacteria
- More likely to disrupt normal flora in the body
- Used when the specific causative bacteria is unknown
narrow spectrum agent
- Drug that treats a relatively limited number of bacteria
- Less likely to disrupt normal flora in the body
- Used when an organism has been identified by culture and sensitivity
side effects of antibiotics
- hypersensitivity
- can be toxic to various organs
- superinfection (disruption of normal flora in the body)
superinfection
Antibiotics that disrupt normal flora
A “new” infection that develops on top of the original infection because of an overgrowth of bacteria
superinfection
example of superinfection
fungal infection:
- vaginal yeast infection (candadiasis)
- thrush in mouth
pseudomembrnous colitis
serious superinfection
cause of pseudomembranous colitis
overgrowth of C-Diff
can happen after antibiotics have been completed
pseudomembranous colitis affects the-
lining of the colon
s&s of pseudomembranous colitis
- severe diarrhea w blood and mucus
- fever
- cramps
bacterial resistance
Many microorganisms have become resistant to antibiotics
culture and sensitivity (C&S) study should be done to specify the -
exact organism and the medication that will be effective before antibiotics are prescribed
identifying bacteria:
- Culture and Sensitivity (C&S)
- Sample of infectious material from skin, Resp Tract, Urinary tract etc obtained
- Placed on culture plate (24-48) hours
- Variety of antibiotics placed on plate
- Control of:
- -no growth = sensitive
- -growth = resistant
nursing interventions
- Assess for results of a C&S to ensure one has been completed before starting on an antibiotic
- Instruct patient to take all of the medication even if symptoms subside to prevent recurrence of the infection
- Failure to complete the prescribed regimen promotes bacterial resistance
many antibiotics will _______ the effectiveness of birth control
