A 78-year-old woman with a long-term indwelling urinary catheter is admitted from a skilled nursing facility with altered mental status, low-grade fever of 38.1°C, and urine that appears cloudy with a strong odor. Her family reports she has been more confused than usual over the past two days but denies any complaints of dysuria or suprapubic pain. Which assessment finding would most strongly support a diagnosis of catheter-associated urinary tract infection (CAUTI) in this client?
- Urinary output of 35 mL/hr over the past 4 hours
- Cloudy urine and strong odor alone as isolated findings
- Heart rate of 88 bpm and blood pressure of 130/82 mmHg
- New-onset confusion and fever in the absence of another identifiable source
