A nurse is caring for a 45-year-old female client diagnosed with acute cystitis. Which nursing intervention should be the priority?

A 28-year-old female client presents to the emergency department with complaints of dysuria, urinary frequency, and suprapubic pain for the past 2 days. Her vital signs are: temperature 101.2°F (38.4°C), pulse 88 bpm, respirations 18/min, and blood pressure 118/76 mmHg. Urinalysis shows positive nitrites, leukocyte esterase, and >100,000 CFU/mL of bacteria. The physician has diagnosed acute cystitis and prescribed antibiotic therapy.

## 보기

1. Encourage increased fluid intake to 2-3 liters per day unless contraindicated **✔ 정답**
2. Apply a heating pad to the suprapubic area for comfort as needed
3. Administer prescribed analgesics for pain relief as ordered
4. Teach the client about proper perineal hygiene techniques today

**정답: 1**

## 해설

Encouraging increased fluid intake is the priority to flush bacteria from the urinary tract, dilute urine to reduce irritation, and support natural defenses, which is synergistic with antibiotic therapy.

Understanding the Priority in Acute Cystitis

For a client with acute cystitis, the immediate physiological goal is to mechanically flush bacteria from the urinary tract. The prescribed antibiotic therapy will eliminate the causative organism, but its effectiveness is enhanced by a non-pharmacological strategy that reduces bacterial load and concentration in the bladder. The data shows a significant bacterial presence (>100,000 CFU/mL), and the client's elevated temperature of 101.2°F (38.4°C) indicates a systemic response to infection. Increasing fluid intake directly addresses the pathophysiology by promoting frequent bladder emptying, which dilutes and expels bacteria, preventing their adherence to the urothelium and further multiplication. This intervention is foundational and safe, with a direct impact on the source of the infection, making it the highest priority before focusing on comfort measures or education [1].

Why Other Options Are Not the Priority

While applying a heating pad, administering analgesics, and teaching perineal hygiene are all appropriate components of care for cystitis, they do not take precedence over a measure that directly combats the infectious process. Comfort interventions like heat application and analgesic administration are secondary to interventions that treat the underlying cause. Similarly, while patient education on hygiene is crucial for preventing recurrence, it is a long-term goal. In the acute phase of a diagnosed infection with systemic signs, an intervention that provides an immediate, non-invasive mechanism to aid bacterial clearance is the priority. The multifaceted interventions described in the literature focus on optimizing management of the current infection, which aligns with prioritizing actions that support the prescribed antimicrobial therapy through mechanical dilution [1, 2].

Connecting Fluid Intake to Antimicrobial Stewardship

The rationale for prioritizing increased fluid intake is strongly supported by antimicrobial stewardship principles. Effective management of urinary tract infections is not solely about selecting the correct antibiotic; it involves supportive measures that optimize the drug's action and reduce the potential for resistance. By encouraging a fluid intake of 2-3 liters per day, the nurse is actively participating in a stewardship strategy. This action increases urine flow, which reduces bacterial stasis and creates a less favorable environment for bacterial growth, thereby working synergistically with the antibiotic. Studies evaluating interventions to improve UTI management highlight that comprehensive care includes non-pharmacological strategies that support the body's natural defense mechanisms and the efficacy of the prescribed treatment, making this a critical nursing action [1, 3].

## 임상 시나리오

Fluid Flush for Acute CystitisNon-Pharmacological Priority Intervention
The priority nursing action is to increase fluid intake to 2-3 liters per day unless contraindicated. This promotes mechanical flushing of the bladder, diluting and expelling bacteria to reduce the infectious load.

This intervention directly addresses the pathophysiology of a urinary tract infection (UTI) with a bacterial count of >100,000 CFU/mL. Frequent voiding prevents bacterial adherence to the urothelium and enhances the effectiveness of prescribed antibiotics.

CautionAssess for contraindications like fluid restrictions due to heart failure or renal disease before encouraging high-volume intake. Monitor intake and output to ensure hydration does not lead to fluid overload.

## 핵심 개념

- **Acute Cystitis** — Inflammation of the bladder, typically caused by a bacterial infection, characterized by dysuria, frequency, urgency, and suprapubic pain.
- **Mechanical Flushing** — The process of using increased fluid intake to increase urine output, physically washing bacteria out of the urinary tract to reduce the bacterial load.
- **Pyelonephritis** — A more severe upper urinary tract infection involving the kidneys, which can be a complication of untreated or poorly managed cystitis.
- **Bacteriuria** — The presence of bacteria in the urine; a count of >100,000 CFU/mL on urinalysis is a significant indicator of a urinary tract infection.
- **Nitrites and Leukocyte Esterase** — Urinalysis markers; positive nitrites indicate bacteria that convert nitrates, and leukocyte esterase indicates the presence of white blood cells, both strongly suggesting a UTI.
