Intrapartum care
Introduction
Intrapartum care is the high-stakes center of maternity nursing, where every contraction, every fetal heart tracing, every assessment carries the weight of two lives. Labor is a physiologic process, but it can shift into an emergency within seconds, requiring nurses to respond with precision, clarity, and calm.
On the NCLEX, intrapartum questions test your ability to prioritize maternal safety, protect fetal oxygenation, and recognize early warning signs that require immediate intervention.
Learning objectives
By the end of this section, you should be able to:
- Describe the stages and phases of labor.
- Interpret fetal heart rate patterns and identify Category I, II, III tracings.
- Recognize obstetric emergencies and apply correct interventions.
- Manage maternal comfort, positioning, and pharmacologic pain relief.
- Provide evidence-based support for physiologic labor and safe delivery.
- Distinguish normal from abnormal labor patterns.
- Apply NCLEX reasoning to “first,” “best,” and “priority” nursing actions.
Stages and phases of labor
Labor occurs in four stages, each with distinct nursing priorities.
Stage 1: Dilation (onset of labor → 10 cm)
Includes three phases. Current ACOG guidance places the start of active labor at 6 cm; transition is the final part of the active phase (8-10 cm), taught separately because its signs and nursing priorities differ. The diagrams on this page use an older 0-3/4-7 cm convention for illustration only - for NCLEX purposes, use the ranges below.
1. Latent phase (0-5 cm or early labor)
- Contractions: mild, irregular → moderate, every 5-10 min
- Client alert, talkative; may be anxious or excited
- Best time for teaching, support, ambulation
Nursing priorities:
- Encourage ambulation, hydration
- Breathing techniques
- Nonpharmacologic pain management
- Assess fetal heart rate (FHR) regularly
2. Active phase (6-7 cm)
- Contractions: moderate to strong, q3-5 min
- Cervical change more rapid
- Increased discomfort; decreased talking
Nursing priorities:
- Continuous monitoring of maternal-fetal status
- Pain management (epidural often placed here)
- Encourage frequent position changes
- Observe for signs of progression
3. Transition phase (8-10 cm)
- Contractions: intense, q2-3 min
- Nausea/vomiting, shaking, irritability
- Urge to push often begins
Nursing priorities:
- Provide reassurance and coaching
- Slow breathing to prevent premature pushing
- Prepare room for delivery
- Monitor FHR closely for distress
Stage 2: Pushing and birth (10 cm → birth)
- Strong urge to push
- Contractions q2-3 min
- Fetal descent through pelvis
- Duration highly variable (minutes → hours)
Nursing priorities:
- Encourage effective pushing techniques
- Maintain open glottis breathing
- Support perineum
- Monitor FHR q5-15 min
- Assist provider with delivery
- Document time of birth, Apgar at 1 and 5 minutes
Stage 3: Delivery of placenta
Usually occurs 5-30 minutes after birth.
Signs of placental separation:
- Gush of blood
- Lengthening of the cord
- Firm, globular uterus rising in abdomen
Nursing priorities:
- Inspect placenta (intact vs missing lobes)
- Administer oxytocin to contract uterus
- Monitor for hemorrhage
- Fundal massage as needed
Stage 4: Immediate postpartum (first 1-2 hours)
Critical period for maternal stability.
Nursing priorities:
- Assess fundus, lochia, vitals q15 min
- Observe for hemorrhage
- Support bonding, breastfeeding initiation
- Manage perineal pain
- Warm blankets, hydration, safety
Fetal heart rate monitoring (NCLEX priority)
Monitoring fetal oxygenation is one of the most heavily tested areas for intrapartum care. This is often estimated through certain adjacent measures, as listed below.
Fetal heart rate characteristics
Baseline fetal heart rate: 110-160 bpm
Variability: variation of the heart rate above or below the baseline heart rate. The most important indicator of fetal oxygenation
- Absent: none (ominous) - sign of lack of oxygenation
- Minimal: ≤ 5 bpm
- Moderate: 6-25 bpm (normal)
- Marked: > 25 bpm
Accelerations
- Increase of 15 bpm x 15 seconds
- Reassuring → fetal well-being
Early decelerations
- Mirror contractions
- Caused by head compression
- Benign
Variable decelerations (V-shaped)
- Cord compression
Interventions:
- Change maternal position
- Discontinue oxytocin
- Administer oxygen
Late decelerations
- Occur after the contraction peak
- Sign of uteroplacental insufficiency
- Interventions (in order):
- Reposition to the left side
- Stop oxytocin
- Oxygen at 8-10 L/min
- IV fluids
- Notify provider
Category I, II, III tracings
Category I (normal)
- Baseline 110-160
- Moderate variability
- May have early decels or accelerations
Category II (indeterminate)
- Minimal or marked variability
- Recurrent variables
- Prolonged decels
- Requires close monitoring + interventions
Category III (abnormal)
Either of the following is Category III — any ONE of the findings in the first bullet is enough:
- Absent baseline variability with any one of:
- Recurrent late decels
- Recurrent variables
- Bradycardia (< 110)
- Sinusoidal pattern on its own, whatever the variability
Requires immediate intervention → possible emergency birth
Pain management in labor
Nonpharmacologic options
- Breathing, relaxation, massage
- Warm baths or showers
- Movement and position changes
- Counterpressure for back labor
Pharmacologic options
Epidural anesthesia
- This is the most common route of administering a combination of local anesthetics (lidocaine) and opioid analgesics (fentanyl). Regional anesthetics eliminate pain below the waist level while leaving the client conscious; it is placed during active labor.
- Watch for hypotension, caused by sympathetic blockade from the local anesthetic (vasodilation below the level of the block). The reduced blood pressure can lead to fetal distress.
Hypotension interventions:
- Preload with fluids
- Left lateral position
- Monitor BP & FHR regularly
- Treat hypotension with fluids + ephedrine if ordered
Systemic opioids
Rather than regional anesthesia with epidurals, intravenous opioids allow systemic analgesia and pain relief. Avoid within 1 hour of delivery as these can cause neonatal respiratory depression
Nitrous oxide
Nitrous oxide is administered as a self-inhaled mixture of 50% nitrous oxide and 50% oxygen via a mask or mouthpiece, allowing the client to control the timing of the dose in coordination with her contractions. This “laughing gas” provides rapid-onset analgesia by increasing endorphin levels and reducing anxiety, while being quickly eliminated from the system to ensure there are no long-term sedative effects on the newborn. It is safe for both the client and the baby.
Obstetric emergencies (NCLEX heavy)
1. Shoulder dystocia
| Shoulder dystocia | Key details |
|---|---|
| Definition | The fetal head is delivered, but the anterior shoulder becomes wedged behind the maternal pubic bone |
| Key sign | Turtle sign - the fetal head retracts against the perineum after delivery |
| Interventions | Perform the McRoberts maneuver and apply suprapubic pressure |
| Avoid | Do not apply fundal pressure because it may worsen impaction and increase the risk of uterine rupture or brachial plexus injury |
2. Umbilical cord prolapse
| Umbilical cord prolapse | Key details |
|---|---|
| Definition | The umbilical cord slips through the cervix ahead of the baby, causing cord compression and fetal hypoxia |
| Immediate interventions | Call for help, elevate the presenting part with a gloved hand, and position the client in knee-chest or Trendelenburg |
| Delivery | Prepare for an emergency cesarean birth |
3. Uterine rupture
Risk: Vaginal birth after C-section (VBAC), high parity, obstructed labor.
| Uterine rupture | Key details |
|---|---|
| Definition | A full-thickness tear in the uterine wall, often at a previous uterine scar |
| Signs and symptoms | Sudden severe abdominal pain, maternal shock, and cessation of contractions |
| Priority action | Treat as an obstetric emergency requiring immediate intervention |
4. Amniotic fluid embolism
A rare but life-threatening condition in which amniotic fluid or fetal debris enters the maternal bloodstream, triggering a rapid systemic inflammatory response, cardiovascular collapse, and coagulopathy.
| Clinical features | Key information |
|---|---|
| Symptoms | Sudden dyspnea that may rapidly progress to cardiac collapse. |
| Management | Provide oxygen, initiate CPR if needed, and activate the emergency response team. |
5. Postpartum hemorrhage during stage 3-4
Defined as cumulative blood loss ≥1000 mL, or blood loss accompanied by signs/symptoms of hypovolemia, within 24 hours of birth, regardless of delivery route. This is most commonly caused by uterine atony and managed with fundal massage and uterotonic medications.
Early recognition saves lives.
Interventions include:
- Fundal massage: stimulates the uterus to contract.
- Oxytocin, methylergonovine, carboprost: these increase the tone of the uterus.
- Treat shock from massive blood loss.
- Locate cause (boggy uterus vs laceration).
Note: Older sources define PPH as >500 mL for vaginal and >1000 mL for cesarean delivery. The current ACOG standard (≥1000 mL with hypovolemia signs, any delivery type) is the definition used for current clinical practice and NCLEX.
