A nurse is assessing a 72-year-old female client who has had an indwelling urinary catheter in place for 5 days following a hysterectomy. The nurse notices the client has a temperature of 100.8°F (38.2°C) and reports flank pain. Which assessment finding would be the priority concern requiring immediate intervention?

Clinical Scenario Analysis

This question presents a classic clinical picture of a catheter-associated urinary tract infection (CAUTI). The 72-year-old post-hysterectomy client has an indwelling urinary catheter for 5 days, a low-grade fever (100.8°F / 38.2°C), and flank pain. CAUTI is the most frequent hospital-acquired infection and a major challenge for nursing quality and infection control ^[3]. The nurse must recognize that flank pain, in the context of an indwelling catheter and fever, suggests the infection may have ascended from the lower urinary tract to the upper urinary tract, specifically the kidneys (pyelonephritis). This progression represents a systemic and potentially life-threatening complication that demands immediate intervention.

Priority Setting and Clinical Reasoning

In NCLEX-RN priority-setting frameworks, systemic involvement and the potential for sepsis take precedence over localized or expected findings. The client’s report of severe pain and urgency to urinate (Option 1) is the most critical finding here. While a catheter is in place, severe pain and urgency indicate significant bladder wall irritation and spasm, often a direct result of the infectious and inflammatory process of a CAUTI . More importantly, in a patient already showing signs of upper tract involvement (fever and flank pain), this symptom signals a worsening infection that could rapidly lead to urosepsis. A case-control study on CAUTI in obstetrics and gynecology patients highlights that understanding specific clinical profiles is crucial for prevention, and the progression of symptoms is a key indicator of severity . The other options represent findings that require monitoring or intervention but are of lower priority. A urine output of 30 mL per hour (Option 2) meets the minimum threshold for adequate renal perfusion and is not an immediate life-threatening concern. Mild discomfort at the insertion site (Option 3) is a common, non-urgent finding that can be addressed with routine catheter care. A small amount of blood-tinged urine (Option 4) is an expected finding after a recent hysterectomy and catheter insertion due to mucosal trauma and is not a priority compared to signs of a severe systemic infection.

Evidence-Based Context for CAUTI Management

The clinical decision-making in this scenario is supported by current evidence on CAUTI. A study on ICU patients identifies CAUTI as a condition that leads to increased morbidity, mortality, and prolonged hospital stays, emphasizing the critical nature of early recognition . The symptom cluster of fever, flank pain, and severe bladder irritability is highly suggestive of a complicated CAUTI that requires immediate urine culture, initiation of empiric antibiotics, and assessment for sepsis. Current best evidence for preventing and optimizing care for adults with indwelling catheters stresses the importance of systematic assessment and prompt intervention when infection is suspected ^[3]. An ongoing randomized controlled trial, the REPLACE study, is even investigating the impact of catheter replacement on recurrence risk in CAUTI, underscoring that the management of the catheter itself is a key clinical decision point . For this client, the immediate priority is to recognize the severity of the condition, notify the healthcare provider, and anticipate orders for urine cultures, antibiotic therapy, and possibly catheter removal or replacement, as current guidelines often suggest catheter change to hasten symptom resolution .
