A nurse is assessing an older adult client who has a urinary tract infection (UTI), Which of the following findings should the nurse identify as unique for this age group?

A. While urinary incontinence is more common in older adults due to age-related changes in the bladder and pelvic floor, it is not specific to UTIs. Incontinence can occur independently from infection as a chronic condition or from other factors like medications, mobility limitations, or neurologic disorders. Therefore, it is not considered a unique or distinguishing symptom of UTI in this population. B. Urinary retention refers to the inability to empty the bladder completely. In older adults, this is often related to prostatic hypertrophy, neurologic disorders, or medications. Although it can contribute to UTI development, retention itself is not a hallmark sign of UTI, and many older adults with UTI will not have retention. C. Low back or flank pain can occur with UTIs in all age groups and is more typical with pyelonephritis than lower urinary tract infections. It is not unique to older adults, as younger adults and children with upper urinary tract infections may also experience similar pain. D. Acute confusion, delirium, or sudden changes in cognitive function is a classic atypical presentation of UTI in older adults. This differs from younger adults, who more commonly present with dysuria, frequency, urgency, and suprapubic pain. Age-related changes in the central nervous system, decreased immune response, and altered inflammatory signaling mean that older adults may not mount the typical symptoms of infection. Confusion may be the first or only indication of a UTI, making it a critical finding for the nurse to recognize. Other nonspecific symptoms can include lethargy, decreased appetite, or falls, emphasizing the need for high vigilance in assessment.
