## 문제

A nurse is assessing a 45-year-old male client who has had an indwelling urinary catheter for 3 days following a spinal cord injury. The nurse notices cloudy, foul-smelling urine with sediment in the drainage bag, and the client reports burning sensation around the catheter insertion site. Which assessment finding would be the priority concern requiring immediate nursing intervention?

## 보기

1. Urine output of 30 mL per hour for the past 4 hours
2. Small amount of blood-tinged urine in the drainage bag
3. Temperature of 101.2°F (38.4°C) with chills and confusion **✔ 정답**
4. Client reports mild discomfort when moving in bed

**정답: 3**

## 해설

A temperature of 101.2°F with chills and confusion indicates systemic infection (likely CAUTI), requiring immediate intervention to prevent sepsis. Other findings are less urgent or expected post-surgery.

Clinical Context and Pathophysiology

The client presents with classic signs of a catheter-associated urinary tract infection (CAUTI), a leading healthcare-associated infection. The presence of an indwelling catheter for 3 days is a critical risk factor, as bacterial colonization increases with the duration of catheterization [1]. The cloudy, foul-smelling urine and sediment indicate a significant bacterial load and pyuria. However, these local signs, along with burning at the insertion site, represent a localized response. The central clinical challenge is differentiating between catheter-associated asymptomatic bacteriuria (CA-ABU) and a symptomatic, systemic infection (S-CAUTI) [1]. The priority is identifying signs that the infection has ascended from the bladder to cause a systemic inflammatory response, which can rapidly progress to urosepsis.

Analysis of Assessment Findings

The nurse must use clinical judgment to prioritize findings that indicate a systemic, life-threatening process over localized or expected complications.

Option 1: Urine output of 30 mL per hour for the past 4 hours

An output of 30 mL/hour is at the lower threshold of adequate renal perfusion and function. While it requires monitoring for acute kidney injury, especially in a spinal cord injury patient who may have neurogenic bladder and hemodynamic instability, it does not immediately signal a systemic infection. This finding is concerning but does not represent the most immediate threat to the client’s survival.

Option 2: Small amount of blood-tinged urine in the drainage bag

A small amount of hematuria is a common and often benign finding in catheterized patients due to traumatic insertion, catheter movement causing mucosal irritation, or bladder spasms. In the context of a CAUTI, hemorrhagic cystitis is possible, but this finding alone is not a marker of systemic severity and is a lower priority than signs of sepsis.

Option 3: Temperature of 101.2°F (38.4°C) with chills and confusion

This is the priority finding. A temperature of 101.2°F (38.4°C), rigors (chills), and an acute change in mental status (confusion) are hallmark signs of a systemic infection and the onset of sepsis. This presentation is consistent with a systemic CAUTI (S-CAUTI), where pathogens have invaded the bloodstream, triggering a profound inflammatory response [1]. In a patient with a spinal cord injury, confusion is an especially critical sign, as it may be the only early indicator of sepsis if sensory deficits mask typical symptoms like flank pain. This finding demands immediate intervention, including obtaining blood and urine cultures and initiating empiric antibiotics, as delays in treating S-CAUTI significantly increase mortality risk.

Option 4: Client reports mild discomfort when moving in bed

Mild discomfort is a non-specific finding that could be related to the catheter itself, the spinal cord injury, or prolonged immobility. While comfort management is a nursing responsibility, this finding is expected and does not signal an acute, life-threatening change in the client’s condition. It is the lowest priority assessment finding.

Clinical Reasoning and NCLEX-RN Application

This question tests the NCLEX-RN principle of prioritization using the ABC (Airway, Breathing, Circulation) and safety frameworks. Systemic infection and sepsis represent an immediate threat to circulation and tissue perfusion. The evidence underscores that while bacteriuria is nearly universal in long-term catheterization, treatment is only indicated when symptomatic infection is present, particularly with systemic signs [1]. The nurse’s role is to recognize the transition from a local, non-critical finding to a systemic, critical one. The combination of fever, chills, and confusion is a classic clinical picture of bacteremia and urosepsis, which requires the most urgent nursing and medical response to prevent septic shock. Evidence-based prevention bundles emphasize not only insertion technique but also daily assessment for early signs of infection to facilitate prompt treatment . The finding of confusion is especially significant, as it represents end-organ dysfunction (cerebral) from the systemic inflammatory response, a defining characteristic of sepsis.References (research sources)

Clinical Practice Guide: Recognizing Systemic Infection in a Catheterized Patient

A patient with an indwelling urinary catheter and localized signs of infection (cloudy, foul-smelling urine, sediment, insertion site burning) must be assessed for progression to systemic illness. The priority is identifying markers of urosepsis, which requires immediate intervention.

Priority Assessment for Systemic Infection

- **Temperature Instability:** A fever of 100.4°F (38°C) or higher, especially with rigors (shaking chills), is a hallmark of systemic inflammatory response syndrome (SIRS) and potential bloodstream infection.

- **Altered Mental Status:** New-onset confusion, lethargy, or agitation in an infected patient is a critical red flag for sepsis and cerebral hypoperfusion, taking precedence over all other findings.

- **Hemodynamic Changes:** Monitor for hypotension, tachycardia, and tachypnea, which indicate the body’s compensatory response to a systemic infection.

Immediate Nursing Interventions

- Notify the healthcare provider immediately and report the vital signs, mental status change, and suspected catheter-associated source.

- Obtain blood cultures and a urine specimen for culture and sensitivity, ideally after replacing the indwelling catheter if it has been in place for more than 7 days, per facility protocol.

- Prepare to administer empiric broad-spectrum intravenous antibiotics as prescribed, and initiate fluid resuscitation if hypotensive.

- Continuously monitor vital signs, oxygen saturation, and level of consciousness every 15 minutes or per sepsis protocol.

Differentiating Localized from Systemic Infection

Localized CAUTI signs (dysuria, suprapubic tenderness, cloudy urine) alone do not constitute a systemic emergency. However, in a spinal cord injury patient with altered sensation, the nurse cannot rely on pain reports and must vigilantly track objective data. The combination of a localized source with new fever and confusion meets the criteria for a sepsis alert, demanding immediate action to prevent progression to septic shock.

## 핵심 개념

- **CAUTI** — Catheter-associated urinary tract infection; a common healthcare-associated infection where an indwelling catheter introduces bacteria into the urinary tract, potentially leading to systemic infection.
- **Urosepsis** — A systemic inflammatory response syndrome (SIRS) caused by a urinary tract infection that has spread into the bloodstream, a life-threatening condition requiring immediate treatment.
- **Neurogenic Bladder** — A loss of normal bladder function caused by a nervous system injury, such as a spinal cord injury, often requiring catheterization and increasing infection risk.
- **Systemic Inflammatory Response Syndrome (SIRS)** — A clinical syndrome characterized by fever, tachycardia, tachypnea, and altered mental status, indicating a widespread inflammatory state often triggered by infection.
- **Indwelling Urinary Catheter** — A flexible tube inserted through the urethra into the bladder to drain urine, with infection risk increasing the longer it remains in place.
