Urinary Tract Infection (Acute Cystitis and Acute Pyelonephritis)
A pregnant client is diagnosed with acute pyelonephritis. Which nursing intervention should be the priority?
A 26-year-old pregnant woman at 28 weeks gestation presents to the emergency department with complaints of severe flank pain, fever of 101.8°F (38.8°C), chills, nausea, and vomiting. Laboratory results show elevated white blood cell count and positive urine culture for E. coli. The physician diagnoses acute pyelonephritis and orders IV antibiotic therapy.

해설
Continuous monitoring of maternal vital signs and fetal heart rate is critical due to risks of sepsis and preterm labor. Other interventions like fluid intake and pain management are important but secondary to early detection of complications.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to prioritize care for a pregnant patient with acute pyelonephritis. This is a serious urinary tract infection that has ascended to the kidneys. In pregnancy, physiological changes (dilated ureters, progesterone-induced smooth muscle relaxation) increase the risk of pyelonephritis. The core danger is not just the infection itself, but its systemic complications: sepsis and the risk of preterm labor triggered by infection and fever. The priority nursing action is always to Key Point! monitor for signs of these life-threatening complications for both mother and fetus.
Answer Rationale: Option ③ is correct. Key Point! Continuous monitoring of maternal vital signs (for signs of sepsis like tachycardia, hypotension, tachypnea, or worsening fever) and fetal heart rate (for signs of fetal distress or uterine irritability indicating preterm labor) is the highest priority. This allows for the earliest possible detection of deterioration, which is the nurse's primary responsibility in this high-risk scenario. Prompt intervention based on this monitoring can prevent maternal septic shock and fetal demise.
Distractor Analysis:
Option ① (Encourage fluids): While adequate hydration is crucial to flush bacteria from the urinary tract and maintain renal perfusion, it is a supportive, not a priority, intervention. In a patient with nausea and vomiting, aggressive oral intake may not be tolerated and could be secondary to IV fluid administration.
Option ② (Left lateral position): The left lateral recumbent position is beneficial in pregnancy to improve uterine blood flow and prevent supine hypotensive syndrome. However, in the context of an acute, systemic infection with fever and potential hemodynamic instability, continuous monitoring for complications takes precedence over positional comfort.
Option ④ (Administer analgesics): Pain management is an important component of compassionate care and can help reduce stress. However, relieving pain does not address the underlying threat of sepsis or preterm labor. Monitoring identifies the problem; analgesics treat a symptom.
Related Concepts: The nursing process dictates that assessment (monitoring) comes before intervention. In any unstable or potentially unstable patient (like one with a systemic infection in pregnancy), the ABCs (Airway, Breathing, Circulation) and surveillance for deterioration are always the priority. This integrates concepts from maternal-newborn nursing (fetal monitoring, preterm labor risks) and medical-surgical nursing (sepsis management, infection).
Concept Summary
Concept
Key Points
Acute Pyelonephritis in Pregnancy
Serious kidney infection. High risk due to urinary stasis. Major complications: maternal sepsis, preterm labor, acute respiratory distress syndrome (ARDS).
Priority Nursing Action
Continuous monitoring of maternal VS and fetal heart rate (FHR) to detect early signs of sepsis or fetal distress.
Supportive Interventions
IV antibiotics, IV fluids for hydration, antipyretics for fever, analgesics for pain, encourage oral fluids once tolerated.
Continuous monitoring for maternal/fetal compromise.
Anatomy, Physiology & Pharmacology Points
Physiology: Progesterone relaxes smooth muscle of ureters, causing dilation and urinary stasis. The enlarging uterus can compress the ureters, further impeding drainage. This creates an environment conducive to bacterial growth.
Pharmacology: IV antibiotics like ceftriaxone or ampicillin/gentamicin are standard. Ensure the drug is safe for pregnancy (Category B usually). Monitor for effectiveness and side effects.
Lab Values: Elevated WBC (>11,000/mm³), positive urine culture with >100,000 CFU/mL. Monitor for rising creatinine indicating impaired renal function.
Memory Tips
Pyelo = PRIORITY. In pregnancy, Pyelonephritis demands Priority monitoring for Preterm labor and Sepsis.
Think "Two Patients": You are caring for the mother AND the fetus. Any action must consider both. Monitoring FHR is non-negotiable.
Mnemonic for Risks:Pyelonephritis causes Preterm labor and Potential sepsis.
High-Frequency NCLEX Topics
The NCLEX loves to test priority-setting and delegation in high-risk obstetric scenarios. Pyelonephritis in pregnancy is a classic topic. Remember: Assessment and monitoring for life-threatening complications always come before comfort measures or routine interventions. You may also see questions on patient education for preventing UTIs or signs of recurrence.
Watch Out for Question Variations!
Symptom Identification: "Which finding in a pregnant client with a UTI most suggests progression to pyelonephritis?" (Answer: Fever and flank pain).
Medication Administration: "The nurse is preparing to administer IV gentamicin to a client with pyelonephritis. Which action is most important?" (Answer: Check peak and trough levels to monitor for nephrotoxicity/ototoxicity).
Patient Education: "Which instruction is most important for the nurse to include when discharging a pregnant client after treatment for pyelonephritis?" (Answer: Report any signs of recurrent infection or contractions immediately).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on the labor & delivery unit admitting "Ms. Jones," a 28-week pregnant patient with a diagnosis of acute pyelonephritis. She is anxious, in pain, and febrile.
Nursing Intervention Strategy:
Immediate Assessment & Monitoring (PRIORITY): Place on continuous electronic fetal monitoring (EFM) and continuous maternal cardiac monitoring or frequent vital signs (every 15-30 minutes initially). Document baseline FHR, variability, and presence of any decelerations or uterine contractions.
Infection Management: Administer prescribed IV antibiotics promptly to achieve therapeutic levels. Obtain blood cultures if ordered prior to antibiotic administration. Administer antipyretics (e.g., acetaminophen) for fever to reduce fetal stress and risk of contractions.
Supportive Care: Initiate IV hydration to correct potential dehydration from fever/vomiting and promote renal flushing. Administer antiemetics and analgesics as needed to keep patient comfortable and able to rest.
Ongoing Evaluation: Monitor for effectiveness of antibiotics (decreasing fever, improving symptoms). Strict intake and output (I&O) monitoring. Assess for signs of preterm labor (regular contractions, pelvic pressure, change in vaginal discharge).
Patient Safety and Precautions:
Sepsis Alert: Be hypervigilant for signs of sepsis: tachycardia, tachypnea, hypotension, altered mental status, or a fever that does not respond to antipyretics. This is an obstetric emergency.
Tocolytic Consideration: If preterm labor contractions begin, the physician may order tocolytic medications (like nifedipine). Understand their administration and monitoring requirements.
Drug Safety: Verify all medications for pregnancy safety. For example, avoid NSAIDs in the third trimester. Monitor renal function with nephrotoxic drugs like gentamicin.
Nursing Procedure & Medication FlowProcedure: Initiating Continuous Fetal Monitoring
1. Explain the procedure to the patient to alleviate anxiety.
2. Apply the ultrasound transducer and tocodynamometer (toco) to the maternal abdomen.
3. Adjust placement to obtain a clear fetal heart rate tracing and to accurately detect uterine activity.
4. Interpret the tracing: Assess baseline FHR, variability, presence of accelerations, and any decelerations.
5. Document findings according to unit protocol and report any non-reassuring patterns (e.g., late decelerations, minimal variability) immediately.
Medication: IV Antibiotic Administration (e.g., Ceftriaxone 1g IV)
- Dilution/Compatibility: Reconstitute according to pharmacy guidelines. Often given in 50-100 mL of compatible IV fluid (e.g., NS).
- Administration Rate: Infuse over 30-60 minutes as per drug guidelines to avoid adverse reactions.
- Key Monitoring: Monitor for allergic reaction (rash, itching, anaphylaxis) during infusion. Observe for improvement in clinical signs (fever, pain) over 24-48 hours.
A Word from Your Senior Nurse
"Nursing in high-risk obstetrics is about being the calm, vigilant guardian for two lives. That mom with pyelo isn't just sick—she's terrified for her baby. Your priority monitoring is your most powerful tool. It's not just watching a screen; it's interpreting the story that the fetal heart rate and mom's vital signs are telling you. Early recognition of a late deceleration or a rising maternal heart rate can trigger a chain of interventions that saves the day. On the NCLEX and in real life, never lose sight of the fact that assessment drives action. Master the 'why' behind the monitoring, and you'll make the right call every time."
