What finding might you expect in a 76-year-old male patient with a urinary tract infection and altered mental status?

In a 76-year-old male patient diagnosed with a urinary tract infection (UTI), the presence of hematuria, or blood in the urine, is an important finding. UTIs can sometimes cause inflammation and irritation of the urinary tract, leading to bleeding. This symptom is particularly relevant in elderly patients, who may present with less typical signs of infection, such as fever or dysuria, and may instead exhibit altered mental status as a common indicator of underlying medical issues.

Finding hematuria indicates that there may be more than just a simple infection; it suggests the involvement of inflammation or other complications affecting the urinary tract. Older adults are at higher risk for such complications, making this sign significant. Therefore, recognizing hematuria can help guide further evaluation and management, including possibly investigating for other causes of bleeding within the urinary system.

The other choices (crushing sensation in the lower back, tearing sensation in the abdomen, and blood in the vomit) are not closely associated with UTIs and do not typically follow the presenting symptoms of a UTI or altered mental status in this age group. These symptoms may indicate other conditions that might not be related to a straightforward urinary infection.
