Thank you all for your suggestions. I should add a bit more history for my Mom. She is considered "mildly cognizant impaired", still toilets herself and is left to her own resources for the most part. I doubt she is able to clean herself properly after a bowel movement so this may be adding to her troubles. She is in one of the 'best' government/veteran's funded nursing homes in the country as she is a war veteran herself. However, the medical system in Canada is quite a mess, underfunded, understaffed and not enough qualified nursing staff in the homes. The home itself is really very nice and unless we went to private care we would be unable to get anything better. Private care is not possible as she has very limited financial means.
I will meet with her doctor next week to discuss preventative measures, both alternative medicine, over the counter options, and traditional treatments, and as also suggested perhaps a daily antibiotic. I will also ask the staff if they could assist in ensuring she is properly cleaned daily to keep the urethra area as clean as possible - but expect they will do this hit and miss.
On a lighter note, I called my Mom tonight to see how she is doing. She said "did I tell you a had a bladder infection"? I had just spent two days with her talking of little else, getting her to drink water and cranberry juice, and making a complete nuisance of myself in the NH trying to get something done. Since then I've been on the internet and consulted with all of you. I just repled "yes, Mom you did mention it". My life has been nothing but about her and my Dad (who recently passed away). She has no idea!
