NCLEX Topic: Fetal Distress
Description:
Fetal distress occurs when the fetus shows signs of compromised oxygenation or inadequate perfusion, which can lead to hypoxia and acidosis. This is a medical emergency that requires immediate intervention to prevent adverse outcomes for the fetus.
Assessment Findings (Signs of Fetal Distress):
1️⃣ Fetal Heart Rate (FHR) Abnormalities:
- Bradycardia: FHR <110 bpm for at least 10 minutes.
- Tachycardia: FHR >160 bpm for at least 10 minutes.
2️⃣ Decelerations:
- Late Decelerations: Caused by uteroplacental insufficiency, occur after the peak of contractions.
- Severe Variable Decelerations: Caused by cord compression, lead to abrupt decreases in FHR.
3️⃣ Baseline Variability:
- Progressive decrease or absent variability indicates compromised fetal oxygenation.
4️⃣ Amniotic Fluid Abnormalities:
- Meconium-stained fluid: Indicates fetal distress, as the fetus may have passed meconium due to hypoxia.
5️⃣ Fetal Activity Changes:
- Hypoactivity or hyperactivity can be a sign of fetal distress.
Causes of Fetal Distress:
- Umbilical cord prolapse or compression
- Uteroplacental insufficiency (e.g., preeclampsia, post-term pregnancy)
- Hyperstimulation of the uterus (e.g., excessive oxytocin administration)
- Maternal hypotension (e.g., supine hypotensive syndrome)
- Infection (e.g., chorioamnionitis)
- Placental abruption or previa
Nursing Interventions for Fetal Distress:
🚨 PRIORITY: Restore fetal oxygenation and prevent hypoxia.
- Discontinue Oxytocin Infusion:
- Stops uterine hyperstimulation and allows the placenta to perfuse better.
- Reposition the Client:
- Place the client in a lateral position (left or right) to relieve pressure on the inferior vena cava and improve uterine blood flow.
- Administer Oxygen:
- Use 8-10 L/min via face mask to improve maternal and fetal oxygenation.
- Administer IV Fluids:
- Give a bolus of IV fluids to improve maternal circulation and placental perfusion.
- Notify the Healthcare Provider:
- If fetal distress persists, the provider may decide on an emergency cesarean delivery.
- Monitor Fetal Heart Rate Continuously:
- Watch for changes in FHR patterns (e.g., persistent bradycardia, late decelerations).
- Prepare for Emergency Cesarean Delivery:
- If distress is unresolved, cesarean delivery is often the next step.
Complications of Untreated Fetal Distress:
- ⚠️ Hypoxia and Acidosis:
- Can lead to fetal brain injury or death.
- ⚠️ Meconium Aspiration Syndrome:
- Occurs when the fetus inhales meconium-stained fluid, leading to respiratory distress.
- ⚠️ Stillbirth:
- In severe cases of unresolved distress.
NCLEX Test-Taking Strategy:
- “Fetal distress”
- “Late decelerations” or “Severe variable decelerations”
- “FHR abnormalities (bradycardia or tachycardia)”
💡 Prioritize based on the ABCs:
- Administer oxygen.
- Reposition the client (lateral).
- Discontinue oxytocin.
Summary for NCLEX:
- ✅ Fetal distress = Medical Emergency.
- 🩺 Key Interventions: Discontinue oxytocin, administer oxygen, reposition, and prepare for cesarean delivery if needed.
- ⚠️ PRIORITY: Restore fetal oxygenation to prevent hypoxia and acidosis.
