Introduction to Preeclampsia and Its Significance
Preeclampsia is a pregnancy-specific hypertensive disorder characterized by high blood pressure and signs of organ dysfunction, typically after the 20th week of gestation. It affects approximately 5-8% of pregnancies and remains a leading cause of maternal and neonatal morbidity and mortality globally.
Key features of preeclampsia include:
- Elevated blood pressure (≥140/90 mm Hg)
- Proteinuria (≥300 mg in a 24-hour urine collection)
- Edema (less specific but common)
- Organ involvement such as liver, kidney, or neurological symptoms
Understanding its pathophysiology, risk factors, and management strategies is essential for optimal patient outcomes.

Case Presentation
Patient Background and Initial Presentation
A 28-year-old primigravida woman at 32 weeks gestation presented to the prenatal clinic with complaints of:
- Severe headaches
- Visual disturbances (blurred vision)
- Sudden swelling in her hands and face
- Occasional epigastric pain
Her medical history was unremarkable, with no prior hypertension or chronic illnesses. She reported good prenatal adherence and recent normal fetal movements.
Vital Signs and Physical Examination
- Blood pressure: 160/110 mm Hg
- Heart rate: 88 bpm
- Respiratory rate: 16 breaths per minute
- Temperature: 98.6°F (37°C)
Physical findings included:
- Mild pitting edema of the lower extremities and face
- No abnormal lung or abdominal findings
- Fetal heart rate: 140 bpm with reassuring patterns

Assessment and Diagnostic Workup
Laboratory and Diagnostic Tests
To confirm preeclampsia and assess severity, the following investigations were ordered:
- Urinalysis for protein: >3+ protein on dipstick, with a 24-hour urine protein of 900 mg
- Complete blood count (CBC): Hematocrit within normal range, no thrombocytopenia
- Serum creatinine and liver function tests: Mild elevation in liver enzymes (AST, ALT)
- Blood pressure monitoring: Confirmed hypertensive readings on multiple occasions
- Ultrasound: Fetal growth appropriate, amniotic fluid normal
Diagnosis
Based on the clinical presentation and laboratory findings, the patient was diagnosed with preeclampsia without severe features, given the elevated blood pressure, proteinuria, and mild organ involvement.

Management Strategies
Effective management of preeclampsia focuses on maternal stabilization, fetal well-being, and timely delivery planning.
Initial Medical Management
- Hospital Admission: The patient was admitted for close monitoring.
- Blood pressure control: Initiated antihypertensive therapy with labetalol, titrated to maintain BP below 140/90 mm Hg.
- Seizure prophylaxis: Magnesium sulfate was administered as per protocol to prevent eclampsia.
- Monitoring: Continuous fetal heart rate monitoring, blood pressure checks every 1-2 hours, and assessment of urine output.
Patient Education and Support
- Explanation of the condition and potential risks
- Signs of worsening condition (e.g., severe headache, visual changes, epigastric pain)
- Importance of adherence to medication and bed rest
- Planning for delivery, considering gestational age and maternal-fetal status
Considerations for Delivery
Since preeclampsia can progress rapidly, the decision for timing and mode of delivery was based on:
- Disease severity
- Gestational age
- Fetal status
- Maternal stability
In this case, as the condition was managed and fetal maturity was sufficient, the healthcare team planned for induction of labor at 34 weeks, unless maternal or fetal compromise necessitated earlier delivery.
---
Outcome and Follow-up
Delivery and Postpartum Course
The patient underwent successful induction of labor at 34 weeks. The delivery was uncomplicated, resulting in a healthy male newborn weighing 2,300 grams with Apgar scores of 8 and 9.
Postpartum, the patient remained hospitalized for 48 hours for continued monitoring. Blood pressure gradually normalized, and magnesium sulfate infusion was discontinued after 24 hours.
Long-term Follow-up
- Blood pressure returned to normal within a week postpartum.
- The patient received counseling on the increased risk of future preeclampsia and advised to have regular follow-up.
- She was scheduled for postpartum check-ups to monitor blood pressure and overall health.

Discussion: Lessons Learned from the Case
This case highlights several critical aspects of preeclampsia management:
Early Recognition and Monitoring
Prompt identification of symptoms such as headaches, visual disturbances, and swelling facilitated early intervention, reducing potential complications.
Importance of Multidisciplinary Care
Coordination between obstetricians, nurses, and specialists ensured comprehensive management, including fetal monitoring and maternal stabilization.
Pharmacologic Interventions
- Labetalol effectively controlled hypertension.
- Magnesium sulfate provided seizure prophylaxis, reducing the risk of eclampsia.
Timing of Delivery
Balancing fetal maturity with maternal health is crucial. In this case, delivery at 34 weeks minimized risks associated with preeclampsia while allowing fetal development.
Postpartum Management and Counseling
Monitoring blood pressure postpartum and informing the patient about future risks are essential components of care.

Frequently Asked Questions
What are the key clinical signs to monitor in a patient with preeclampsia?
Key signs include elevated blood pressure, proteinuria, headaches, visual disturbances, upper abdominal pain, and edema. Regular monitoring helps detect worsening conditions.
How does preeclampsia affect fetal well-being?
Preeclampsia can reduce placental blood flow, leading to fetal growth restriction, decreased oxygenation, and even preterm birth if severe conditions develop.
What are the nursing interventions for managing a patient with preeclampsia?
Interventions include monitoring blood pressure and urine output, assessing for signs of seizure activity, administering antihypertensives as prescribed, promoting bed rest, and educating the patient about warning signs.
What are the potential complications of preeclampsia for both mother and fetus?
Maternal complications can include eclampsia, stroke, organ failure, and HELLP syndrome. Fetal risks involve prematurity, low birth weight, placental abruption, and fetal distress.
When is delivery indicated in a case of preeclampsia?
Delivery is indicated when preeclampsia becomes severe, maternal or fetal health is at risk, or after 37 weeks of gestation in mild cases, to prevent progression to eclampsia or other complications.
What role does patient education play in preeclampsia management?
Patient education is vital to ensure understanding of medication adherence, recognizing warning signs, the importance of regular prenatal visits, and when to seek immediate care.
