that results from indwelling catheters?
I wanna say e.coli but not 100% sure
I believe it's S. epidermidis.
i think its staph most commonly. staph epi maybe?
staph epi or staph aureus?
staph epi im pretty sure
it forms biofilms on medical equipment that is normally made so bacteria cant stick. i forgot why but for some reason staph epi can stick to and make thin films (colonies) of bacteria on catheters and such.
Depends on what type of catheter, que no?
First Aid 2008 Page 174: Nosocomial Infections:
Urinary catheterization: E. coli, Proteus
Staph epi, bio film, prosthesis, catheters (lines) etc. Unless you are talking about Foley Catheter, then E. coli.
It's E. coli...catheterization or not. Staph epi is second most common and is more specific to catheterization. However, E. coli is still most common because its native to the vaginal canal.
I remember one specific question about a woman who kept getting UTIs after having sex with her husband. The question asked how she could avoid getting UTIs and the answer was if she voided more often after sex. She was getting E. coli UTIs...think of a cath as similar to a penis in a vagina.
It really depends on the site of the catheter, as in Foley or central venous. Venous is s. epidermidis/S. aureus (both are normal microbial flora of the skin, but S. epi is probably the cause due to biofilm ). As for Foley catheters, E. coli is usually #1.
As for the husband who kept giving his wife a UTI, Airmonkey84, I highly doubt that the answer choice would include E. coli, but the testers would most likely want you to pick S. saprophyticus. Think about a sexually active female with recurrent UTI's, 2nd most common cause, I can see them testing that, or maybe the fact that she's suffering from improper voiding and has cystitis.
I misinterpreted...sorry thought you were talking about urinary catheters. If it's urinary catheters then its E. coli. If it's a venous cathether then Gynguy is right.
I'm pretty sure that E. coli is still the most common cause in sexually active women though.
That it is, but S. saprophyticus is #2, and I think they would want to test whether or not you know that there could be another cause, otherwise, E. coli would be the MCC of UTI in everyone all the time. Where's the fun in testing that?
"[FONT=verdana, arial, helvetica, sans-serif]In vitro susceptibility testing showed almost uniform sensitivity of S. saprophyticus to most antimicrobials used to treat UTIs, but recurrent infections occurred in six of the 72 women despite adequate therapy. Physicians and microbiologists must be aware that S. saprophyticus is an important cause of UTIs in young women."
For that question, i think i put voiding but i know i was contemplating douching as the choice.
Was "have buttsechs only" an answer choice? That'd solve it.
"Sorry honey; doctor's orders..."
That's what I would have put also, or perhaps the vignette had something that would have given a clue about some meds that she took that could cause urinary retention like H1 blockers.
You're married. I'm pretty sure you know the answer to that one.
