Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse in Labor & Delivery. Your patient, Maria, is 40 weeks G1P0, receiving oxytocin for labor augmentation. You are reviewing the EFM strip and note the contractions are every 2 minutes, lasting 90 seconds (tachysystole). The FHR baseline is 140, but with each contraction, the heart rate slowly drops to 120, reaching its lowest point after the contraction peaks, and takes 30 seconds after the contraction ends to return to baseline. This has happened 5 times in a row.
Nursing Intervention Strategy:
1. Assessment: Immediately confirm the pattern is repetitive late decelerations. Check maternal vital signs (BP may be low). Assess contraction pattern (may be hypertonic).
2. Immediate Actions (Intrauterine Resuscitation):
• Position: Say, "Maria, I need you to roll onto your left side, please," and assist her. Use pillows for support.
• Oxygen: Apply a non-rebreather face mask at 10-12 L/min to achieve an FiO2 close to 100%.
• IV Fluids: Increase the rate of the primary IV line (usually Lactated Ringer's) to a rapid bolus as per protocol (e.g., 500-1000 mL bolus) to increase maternal intravascular volume.
• Medication: Key Point! If oxytocin is infusing, STOP IT IMMEDIATELY at the pump and clamp the secondary line.
3. Communication: Use the call bell/system to alert the charge nurse and healthcare provider (physician/midwife) STAT. Report using SBAR: Situation (repetitive late decels), Background (patient on oxytocin), Assessment (maternal status, actions taken), Recommendation (provider needs to come assess now).
4. Ongoing Monitoring & Preparation: Continuously monitor FHR and contraction pattern for improvement. Prepare for possible emergency procedures: have crash cart accessible, ensure consent is signed, and prepare the operating room if a cesarean section is imminent.
Patient Safety and Precautions:
• Never leave the patient unattended during this event.
• Avoid the supine position at all costs during resuscitation.
• Document every action, change in FHR, notification time, and provider response meticulously.
• Understand that if intrauterine resuscitation fails to correct the pattern, expedited delivery is the definitive treatment for fetal hypoxia.
Nursing Procedure & Medication Flow
Procedure: Intrauterine Fetal Resuscitation
1. Identify non-reassuring FHR pattern (Late/Variable decels, bradycardia).
2. Call for help (Charge nurse/other staff).
3. Positioning First: Left lateral or right lateral. If cord prolapse is suspected, use Trendelenburg or knee-chest.
4. Oxygen Administration: Apply tight-fitting non-rebreather mask at 10-12 L/min.
5. IV Fluids: Open main IV line to wide open or bolus per order/protocol.
6. Discontinue Uterotonic Agents: Stop oxytocin/Pitocin infusion. If receiving prostaglandins, remove vaginal insert if applicable.
7. Notify Provider: Give clear, concise SBAR report.
8. Consider Tocolytic: If uterine hyperstimulation is present, provider may order Terbutaline 0.25 mg SQ to relax the uterus.
9. Prepare for Delivery: Assist with procedures (amnioinfusion for variables, operative vaginal delivery, or cesarean section).
Medication Alert - Oxytocin (Pitocin):
• Action: Stimulates uterine contractions.
• Major Side Effect: Uterine hyperstimulation (contractions >5 in 10 min, lasting >90 sec, or resting tone >20-25 mmHg), leading to fetal hypoxia.
• Nursing Priority: Constant monitoring of FHR and uterine activity. At first sign of non-reassuring FHR or hyperstimulation, STOP THE INFUSION.
A Word from Your Senior Nurse
"Remember, you are the eyes and ears for that baby who can't speak for itself. Interpreting that fetal monitor strip is a critical skill. When you see those late decelerations, don't panic—but do act swiftly and decisively. Your quick thinking with left-side positioning and oxygen can literally save a baby's life by buying time. On the NCLEX, they want to see that you know the immediate, independent nursing actions before you even call the doctor. In real life, you'll often do these steps simultaneously while your partner calls the provider. This integrated thinking—connecting the pathophysiology (placental insufficiency) to the intervention (improving blood flow)—is what makes a great nurse."
