A nurse is caring for an older adult patient who has a urinary tract infection (UTI). Which of the following manifestations should the nurse identify as a finding specifically associated with this client?

Choice A rationale Urinary retention is a common symptom of various genitourinary conditions in older adults, such as benign prostatic hyperplasia or medication side effects. While it can occur with a UTI, it is not a specific or unique manifestation of a UTI in this population, as it is also a symptom of other conditions. Choice B rationale Incontinence can be a symptom of a UTI, particularly in older adults who may have weakened bladder control. However, new-onset incontinence can also be related to other issues such as weakened pelvic floor muscles, medications, or neurological conditions, making it a non-specific finding. Choice C rationale Confusion or a sudden change in mental status is a hallmark and often the only sign of a urinary tract infection in older adults. Due to an altered immune response and less localized inflammatory response, they may not exhibit classic symptoms like dysuria or fever, making confusion a specific and critical indicator of infection. Choice D rationale Low back pain can be a symptom of a urinary tract infection, particularly if the infection has ascended to the kidneys (pyelonephritis). However, low back pain is a very common complaint in older adults due to musculoskeletal issues, arthritis, and other conditions, which makes it a non-specific and unreliable indicator.
