    Dear, your mother might have urinary tract infection, as she is vulnerable. Is better to give intravenous quinolone antibiotic for five days, if not contraindicated. What type of kidney problem she have is important in prescribing medications. She should take complete bed rest and provide nutritional liquid foods.
