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. Urinary retention: While urinary retention can occur with a UTI, it is not unique to older adults and can occur in younger clients as well, often due to obstruction or neurological issues. B. Incontinence: Incontinence may accompany UTIs, especially in older adults, but it can also be present for other reasons such as mobility issues or chronic conditions. It is not a symptom unique to this age group. C. Confusion: In older adults, a UTI is a common cause of delirium (sudden, fluctuating confusion). This happens because the aging immune system may not produce a high fever or high white blood cell count immediately; instead, the systemic stress of the infection affects the central nervous system. D. Low back pain: Low back pain can be associated with UTIs or pyelonephritis in any age group. While it is a relevant symptom, it is not specific or unique to older adults.
