GI Meds Flashcards
define pathogen
an organism causing disease to its host
what can bacteria be identified with?
a culture and sensitivity test or a gram stain test
what are the 2 types of antimicrobials?
broad-spectrum or narrow-spectrum
what are the 2 types of antibiotics?
bacteriostatic and bactericidal
define culture, where is it collected from, how it is used to identify the pathogens
a test is performed to examine different body substances for the presence of bacteria or fungus, collected by the nurse from pt’s blood, urine, sputum, wound bed etc., then incubated in a growth-promoting environment to identify
define sensitive analysis
a test performed in addition to a culture in order to select an effective antibiotic to treat the microorganism
define gram stain
a test used to quickly diagnose bacterial infection, ID the bac as gram +/-, assist the HCP in selecting the appropriate antibiotic to treat the infection. pos=violet, neg=red/pink
example of a gram positive bacteria
MRSA
example of a gram negative bacteria
N. gonorrhoeae, E.coli
define narrow spectrum
targets only specific subsets of bacterial pathogens
define broad specturm
targets a wide variety of bacterial pathogens, including gram +/- specis
what will broad treat and what will narrow treat (+/-)
broad = both narrow = one or the other
define bacteriostatic
stop bacteria from reproducing may not kill it
define bactericidal
kill the target bacteria (need this one if immunocompromised)
define synergistic interactions
concurrent drug administration producing a synergistic interaction that is better than the efficacy of either drug alone
