Preeclampsia is a pregnancy-related hypertensive disorder characterized by high blood pressure that develops after 20 weeks of pregnancy and may be accompanied by signs of maternal organ dysfunction. It can affect both the mother and the fetus and requires careful monitoring and timely management. If left untreated, preeclampsia can progress to eclampsia, a serious condition characterized by seizures.
Nurses play an important role in recognizing early warning signs, monitoring the mother and fetus, administering prescribed medications, preventing complications, and providing health education.
Signs and Symptoms
Common signs and symptoms of preeclampsia include:
- Elevated blood pressure
- Protein in the urine or other evidence of organ involvement
- Severe or persistent headache
- Blurred vision or other visual disturbances
- Swelling, particularly of the face and hands
- Sudden weight gain due to fluid retention
- Upper abdominal or epigastric pain
- Nausea or vomiting
- Decreased urine output
- Shortness of breath in severe cases
Some women may have few or no noticeable symptoms, which is why regular prenatal assessment and blood pressure monitoring are important.
Nursing Assessment
The nurse should closely monitor the mother’s condition and watch for signs that indicate worsening disease. Blood pressure should be measured accurately and regularly. The nurse should also assess the patient’s neurological status, deep tendon reflexes, urine output, respiratory status, and presence of edema.
Laboratory results such as platelet count, liver enzymes, kidney function tests, and urine protein may also be monitored as ordered.
Fetal assessment is equally important. The nurse may monitor fetal heart rate, fetal movement, and other ordered assessments to evaluate fetal well-being.
Nursing Care Plan
Nursing Diagnosis 1: Risk for Injury
Related to: Increased risk of seizures secondary to severe preeclampsia.
Goal: The patient will remain free from injury and demonstrate no evidence of seizure activity.
Nursing Interventions:
- Monitor for severe headache, visual disturbances, hyperreflexia, and epigastric or right-upper-quadrant pain.
- Maintain seizure precautions when indicated.
- Keep the patient’s environment quiet and minimize unnecessary stimulation.
- Ensure oxygen and suction equipment are readily available.
- Administer magnesium sulfate as prescribed.
- Monitor respiratory rate, urine output, and deep tendon reflexes while magnesium sulfate is being administered.
- Report signs of magnesium toxicity or worsening neurological symptoms immediately.
Rationale: Severe preeclampsia can progress to eclampsia. Early recognition and seizure precautions help reduce the risk of maternal injury.
Nursing Diagnosis 2: Excess Fluid Volume
Related to: Fluid retention and altered vascular permeability associated with preeclampsia.
Goal: The patient will maintain appropriate fluid balance and remain free from complications such as pulmonary edema.
Nursing Interventions:
- Monitor intake and output accurately.
- Assess for peripheral and facial edema.
- Monitor daily weight when appropriate.
- Auscultate lung sounds regularly.
- Monitor oxygen saturation.
- Administer IV fluids carefully according to the prescribed treatment plan.
- Report decreased urine output, increasing edema, crackles, or difficulty breathing.
Rationale: Preeclampsia may cause abnormal fluid distribution and increase the risk of pulmonary edema.
Nursing Diagnosis 3: Anxiety
Related to: Threat to maternal and fetal health.
Goal: The patient will verbalize decreased anxiety and demonstrate understanding of her condition and treatment.
Nursing Interventions:
- Explain procedures and treatments clearly.
- Encourage the patient to express fears and concerns.
- Provide emotional support and reassurance.
- Encourage appropriate family support.
- Teach the patient which symptoms should be reported immediately.
Rationale: Understanding the condition and receiving appropriate support can help reduce anxiety and improve cooperation with treatment.
Medical Management
Management depends on the severity of preeclampsia, gestational age, and the condition of the mother and fetus. Treatment may include close monitoring, antihypertensive medication for severe hypertension, and magnesium sulfate for seizure prevention in patients at risk of eclampsia.
When pregnancy must be ended because of severe maternal or fetal complications, delivery may be necessary. The healthcare team considers the risks and benefits of continuing the pregnancy versus delivery.
Health Education
The nurse should teach the patient to seek immediate medical attention if she develops:
- Severe or persistent headache
- Blurred vision or other visual changes
- Severe abdominal or upper abdominal pain
- Difficulty breathing
- Seizure activity
- Significant decrease in fetal movement
- Sudden worsening swelling
Patients should also be encouraged to attend prenatal appointments and follow their healthcare provider’s instructions regarding blood pressure monitoring, medications, laboratory tests, and fetal monitoring.
Conclusion
Preeclampsia is a potentially serious pregnancy complication that requires early recognition and careful management. Nursing care focuses on monitoring maternal and fetal status, controlling blood pressure as prescribed, preventing seizures and other complications, maintaining fluid balance, and providing emotional support and education. Through close observation and timely intervention, nurses contribute significantly to the safety of both the mother and the fetus.
