A postpartum client on her second day after vaginal delivery reports burning sensation during urination, urinary frequency, and urgency. Her vital signs are: temperature 100.2°F (37.9°C), pulse 88 bpm, respirations 18/min, and blood pressure 118/76 mmHg. What is the most appropriate initial nursing intervention?
1Administer the prescribed antibiotic as soon as possible
2Encourage the client to drink 3000 mL of fluid daily
3Apply a warm compress to the suprapubic region for relief
4Obtain a clean-catch midstream urine for culture and sensitivity✓ 정답
해설
The most appropriate initial nursing intervention is to obtain a clean-catch midstream urine specimen for culture and sensitivity to confirm diagnosis before treatment. Other options are important but should follow diagnostic confirmation.
Clinical Context
This postpartum client presents with classic signs of a lower urinary tract infection (UTI): dysuria (burning), urinary frequency, and urgency. The low-grade temperature of 100.2°F (37.9°C) is a common systemic response, while the remaining vital signs are within normal limits. In the postpartum period, the hypoestrogenic state and potential for bladder trauma during vaginal delivery increase susceptibility to UTIs, a phenomenon related to the broader spectrum of Genitourinary Syndrome of Lactation (GSL)[3].
Why Not the Other Options?
Before initiating any treatment, the nurse must first confirm the presence and causative organism of the infection. Administering an antibiotic (Option 1) without a specimen for culture and sensitivity is premature and contributes to irrational antibiotic use, a practice specifically cautioned against in UTI management [1]. While increasing fluid intake (Option 2) and applying a warm compress (Option 3) are comfort measures that can be implemented, they do not address the priority nursing action of identifying the pathogen to guide targeted therapy.
The Priority: Diagnosis Before Treatment
The most appropriate initial nursing intervention is to obtain a clean-catch midstream urine specimen for culture and sensitivity (Option 4). This aligns with clinical guidelines that recommend a midstream urine sample as the standard for diagnosing UTIs when a patient is symptomatic [2]. The clean-catch technique minimizes contamination from the perineum, which is particularly important in a postpartum client with ongoing lochia. The culture identifies the specific pathogen—most commonly Escherichia coli—and the sensitivity determines which antibiotic will be effective, ensuring judicious antimicrobial stewardship [1]. Only after the specimen is collected should the nurse proceed with comfort measures and administer the prescribed antibiotic once the results guide the selection.

Clinical Assessment for Postpartum UTI
Evaluate for classic lower UTI symptoms: dysuria, urinary frequency, and urgency. Note low-grade fever (commonly 37.8-38.3°C) as a systemic response. Assess for risk factors including recent vaginal delivery, catheterization, and hypoestrogenic state during lactation.
Diagnostic Priority: Specimen Collection
Obtain a clean-catch midstream urine specimen before initiating antibiotics. Instruct the patient to cleanse the perineum from front to back, begin voiding, then collect the midstream sample in a sterile container. This minimizes contamination and ensures accurate culture results.
Nursing Intervention Sequence
Collect urine for culture and sensitivity as the first action.
Administer prescribed antibiotics only after the specimen is obtained.
Encourage fluid intake of 2000-3000 mL/day to promote bladder flushing.
Apply warm compresses to the suprapubic area for comfort as needed.
Patient Education
Teach proper perineal hygiene, complete antibiotic course adherence, signs of worsening infection (fever, flank pain), and the importance of follow-up if symptoms persist.
Clean-catch midstream urine specimen — A urine collection method where the genital area is cleansed, and urine is collected midstream to minimize contamination for accurate culture and sensitivity testing.
Culture and sensitivity — A laboratory test that identifies the specific bacteria causing an infection and determines which antibiotics will be effective against it.
Dysuria — Painful or difficult urination, often described as a burning sensation, commonly associated with urinary tract infections.
Genitourinary Syndrome of Lactation (GSL) — A hypoestrogenic state during lactation that can cause vulvovaginal and urinary tract symptoms, increasing susceptibility to UTIs postpartum.
