Learning Objectives

Perform an intrapartum assessment—contractions, cervical dilation/effacement/station, fetal heart rate, and rupture of membranes.
Identify the stages of labor and the 5 P's that influence labor progress.
Interpret fetal heart-rate patterns (VEAL CHOP; variability, accelerations, decelerations) and recognize reassuring vs. non-reassuring tracings.
Recognize the emergencies that require immediate action—cord prolapse, late/prolonged decelerations, uterine tachysystole, and hemorrhage.
Use the NCSBN Clinical Judgment model to recognize cues, prioritize, and act—and answer NCLEX-style items.

Why Assessment Matters

Patient safety: labor is dynamic and the nurse cares for two patients. Ongoing assessment tracks labor progress and catches emergencies—fetal distress, cord prolapse, uterine tachysystole, and hemorrhage—where minutes matter.

Early recognition: non-reassuring signs often appear on the fetal monitor before anything else—reduced variability, late decelerations, or a sudden drop after membranes rupture. The nurse who reads the tracing acts first.

Prevention of complications: recognizing abnormal fetal heart-rate patterns, a prolapsed cord, or excessive contractions and intervening quickly prevents fetal hypoxia and injury.

Clinical judgment: the nurse integrates contraction pattern, cervical change, fetal monitoring, and maternal status to decide what's normal progress, what's abnormal, and what needs immediate action.

Connecting to A&P Recall that oxytocin drives contractions (positive feedback) and the placenta oxygenates the fetus. Assessment checks whether the powers (contractions) are moving the passenger (fetus) through the passageway (pelvis/cervix) while the fetus stays well-oxygenated—read from contractions, cervical change, and the fetal heart rate.

Health History (Admission)

Component	What to ask & WHY it matters
Chief complaint / reason for admission	Contractions, rupture of membranes, bleeding, or decreased fetal movement—determines urgency and next steps.
History of present labor	Contraction onset, frequency, duration, and intensity; whether the bag of water broke (time, color, amount, odor); and bleeding/"bloody show"—assesses labor stage and risk.
Obstetric history (GTPAL) & EDD	Gestational age (term/preterm), parity, prior labors/cesareans (VBAC risk), and complications—shape the plan.
Prenatal course	Preeclampsia, gestational diabetes, GBS status, and Rh type—guide intrapartum care (e.g., GBS antibiotics).
Medications/allergies	Current meds, anticoagulants, and allergies—safety for medications/anesthesia.
Social history	Support person, substance use, and preferences/birth plan.
Review of systems / danger signs	Headache/visual changes (preeclampsia), bleeding, fever, and fetal movement—screen for complications.

NCLEX pearl — always assess the fetal heart rate after membranes rupture When the membranes rupture (spontaneous or artificial), the first nursing action is to assess the fetal heart rate—a sudden drop can signal umbilical cord prolapse (the cord slips down and gets compressed). Also note the fluid's time, color (clear vs. meconium-stained/green), amount, and odor.

Inspection

What the nurse observes: the perineum and vaginal output—bloody show, amniotic fluid (color/amount), bleeding, crowning, and signs of imminent birth; plus maternal behavior/pain and general status.

Observation	Normal findings	Abnormal findings & significance
Bloody show	Pink/blood-tinged mucus as the cervix dilates	Bright red bleeding (placenta previa/abruptio)—not normal show
Amniotic fluid	Clear fluid with rupture of membranes	Green/meconium-stained (possible fetal distress), foul odor (infection), or bloody/port-wine (abruptio)
Perineum	No crowning until second stage	Crowning/bulging perineum, urge to push → imminent delivery (prepare!)
Maternal behavior	Coping/breathing with contractions	Sudden severe pain, restlessness, or "the baby is coming" → assess for rapid progress/complications

Why meconium-stained fluid matters Green (meconium-stained) amniotic fluid means the fetus passed stool in utero—often a sign of fetal stress/hypoxia and a risk for meconium aspiration at birth. Notify the provider, monitor the FHR closely, and prepare for possible neonatal resuscitation. Always note fluid color at rupture.

Palpation

Technique: palpate contractions (place fingertips on the fundus—assess frequency, duration, and intensity/resting tone), perform a cervical exam (dilation, effacement, station) and Leopold's maneuvers (fetal presentation/position), and assess the bladder (a full bladder impedes descent).

Finding	Normal	Abnormal & nursing implications
Contractions	Regular, with adequate rest/relaxation between; increasing frequency/intensity as labor progresses	Tachysystole (>5 contractions/10 min, or no rest between) → reduced fetal oxygenation (stop oxytocin)
Cervical dilation	0 → 10 cm (10 = complete)	Arrest of dilation (no change) → labor dystocia
Effacement	0 → 100% (thinning)	Slow effacement with an unfavorable cervix
Station	−5 (high) → 0 (engaged, at the ischial spines) → +5 (crowning)	No descent → labor dystocia; rapid descent → imminent birth
Uterine resting tone	Soft between contractions	Firm/no relaxation between → tachysystole; a rigid, tender uterus → abruptio

Safety — feel for the cord and the resting tone During/after a cervical exam or rupture, if you feel a pulsating cord or the fetal heart rate suddenly drops, suspect cord prolapse—an emergency (see red flags). And the uterus must relax between contractions so the placenta can re-oxygenate the fetus; no rest between contractions (tachysystole) starves the fetus of oxygen.

Percussion

Purpose: percussion is not used in labor assessment. If the client has preeclampsia, the nurse may check deep tendon reflexes (a percussion-based test) for CNS irritability/magnesium status—otherwise labor is assessed by palpation, inspection, and fetal monitoring.

	Expected findings	Abnormal findings
Deep tendon reflexes (if preeclampsia)	2+ (normal)	Hyperreflexia/clonus (preeclampsia) or absent (magnesium toxicity)

Note: the core of labor assessment is palpation (contractions/cervix), inspection, and continuous fetal/uterine monitoring.

Auscultation (Fetal Monitoring)

Technique: monitor the fetal heart rate (FHR) and uterine contractions—by intermittent auscultation (Doppler) or continuous electronic fetal monitoring (EFM). Evaluate baseline rate, variability, accelerations, and decelerations, and correlate with contractions.

Component	Reassuring / normal	Non-reassuring / abnormal
Baseline FHR	110–160 bpm	Bradycardia (<110) or tachycardia (>160)
Variability	Moderate variability (a reassuring sign of a well-oxygenated fetus)	Absent/minimal variability → possible hypoxia/acidosis
Accelerations	Present (reassuring—fetal well-being)	Absent (less reassuring in context)
Decelerations	Early decels (mirror contractions—benign, head compression)	Late decels (placental insufficiency) and variable decels (cord compression) → intervene

Why VEAL CHOP is the FHR decoder VEAL CHOP matches each pattern to its cause: Variable = Cord compression; Early = Head compression (benign); Accelerations = Okay; Late = Placental insufficiency. For late decels (ominous), act with "LION": Left side, IV fluids up, Oxygen, Notify (and stop oxytocin). For variable decels, reposition (relieve cord compression) and, if severe, consider an amnioinfusion per order.

Assessment Tools & the Stages of Labor

Cervical dilation/effacement · fetal station · stages of labor Dilation & Effacement 0 cm 5 cm 10 cm (complete) Dilation 0→10 cm · Effacement 0→100% Fetal Station −5 (high) 0 = ischial spines (engaged) +5 (crowning) Head descends −5 → +5 The 5 P's Passenger (fetus) Passageway (pelvis/cervix) Powers (contractions) Position (maternal) Psyche (coping) The 4 Stages of Labor Stage 1 — Dilation Latent, Active, Transition (0→10 cm) Stage 2 — Pushing Full dilation → birth Stage 3 — Placenta Birth → placenta delivery Stage 4 — Recovery First ~1–2 h postpartum (watch bleeding) Fetal heart rate: 110–160 bpm · moderate variability & accelerations = reassuring Late decels (placental) & absent variability = non-reassuring → act (VEAL CHOP / LION)

Labor is tracked by dilation (0→10 cm), effacement (0→100%), and station (−5→+5) and shaped by the 5 P's. The four stages run from dilation → pushing → placenta → recovery. Throughout, the fetal heart rate (110–160 with moderate variability/accelerations) tells you the fetus's status.

Tool	Purpose	Interpretation & clinical significance
Cervical exam (dilation/effacement/station)	Track labor progress	Dilation 0→10, effacement 0→100%, station −5→+5; "10 cm, 100%, +2" = advanced labor.
Contraction assessment (palpation/tocodynamometer)	Assess the "powers"	Frequency (start-to-start), duration, intensity, and resting tone; tachysystole is abnormal.
Electronic fetal monitoring (EFM)	Assess fetal oxygenation	Category I (normal/reassuring), II (indeterminate), III (abnormal—act). Read with VEAL CHOP.
Leopold's maneuvers	Determine fetal presentation/position	Guides FHR placement and delivery planning.
Bishop score	Assess cervical readiness for induction	Higher score = more favorable cervix for successful induction.

Focused Assessment

1. Admission history & status: contractions, rupture of membranes (time/color/odor), bleeding, fetal movement, GTPAL/EDD, prenatal risks, and maternal vitals. ↓ 2. Assess contractions (the "powers"): frequency, duration, intensity, and resting tone (palpation ± tocodynamometer). ↓ 3. Cervical exam: dilation, effacement, and station; Leopold's for presentation/position. ↓ 4. Fetal monitoring: baseline FHR (110–160), variability, accelerations, and decelerations—correlate with contractions (VEAL CHOP). ↓ 5. After rupture of membranes: assess the FHR first (rule out cord prolapse), note fluid color/amount/odor, and continue monitoring. ↓ 6. Correlate & act: connect labor progress and fetal status; identify the stage, anticipate delivery, and respond to non-reassuring signs.

Priority findings: cord prolapse, late/prolonged decelerations or absent variability (fetal distress), uterine tachysystole, heavy bleeding, and signs of imminent birth—act immediately.

Red Flag Findings

Finding	Possible cause	Immediate nursing action
Sudden FHR drop / visible or palpable cord after ROM	Umbilical cord prolapse	Emergency: relieve cord pressure—place in knee-chest or Trendelenburg, lift the presenting part off the cord with a gloved hand, give oxygen, call for help, prepare for emergency cesarean. Do NOT push the cord back in.
Late decelerations / minimal-absent variability	Placental insufficiency / fetal hypoxia	Left side, oxygen, ↑IV fluids, stop oxytocin, notify provider (LION).
>5 contractions/10 min or no rest between (tachysystole)	Uterine tachysystole (often oxytocin)	Stop/reduce oxytocin, reposition, IV fluids, oxygen, notify provider.
Bright red bleeding / rigid, painful uterus	Placenta previa/abruptio	VS, fetal monitoring, IV access, notify provider; no vaginal exam if previa suspected.
Meconium-stained (green) fluid	Possible fetal distress	Monitor FHR, notify provider, prepare for neonatal resuscitation.
Crowning / strong urge to push	Imminent delivery	Do not leave; call for help, prepare for delivery, support the perineum.

Documentation

Document findings objectively, specifically, and by time—labor progress, contractions, fetal status, and any interventions.

Weak (vague)	Strong (specific, measurable)
"In labor, doing okay."	"Cervix 6 cm / 90% effaced / 0 station. Contractions every 3 min, 60 sec, moderate, with good resting tone. FHR 140s, moderate variability, accelerations present, no decelerations. Coping with breathing techniques."
"Water broke."	"SROM at 1420; clear fluid, moderate amount, no odor. FHR assessed immediately: 138 with moderate variability, no decelerations. No cord felt/visible. Provider notified."
"Heart rate dropped."	"Late decelerations noted with contractions at 1500; repositioned to left side, O₂ 10 L/min via non-rebreather, IV fluids increased, oxytocin stopped, provider notified. FHR recovered to 140s with moderate variability."

Documentation tip Record dilation/effacement/station, contraction frequency/duration/intensity/resting tone, FHR baseline/variability/accels/decels, ROM (time/color/amount/odor), and interventions with times and provider notification. Time-stamped, specific notes show labor progress and fetal status trends.

Clinical Judgment

Recognize cues: shortly after the membranes rupture, the fetal monitor shows a sudden, prolonged drop in the fetal heart rate, and on exam the nurse feels a pulsating cord in the vagina. The presenting part is high.
Analyze cues: a sudden FHR drop after ROM + a palpable pulsating cord = umbilical cord prolapse—the cord is compressed between the presenting part and the pelvis, cutting off fetal oxygen. This is an obstetric emergency.
Prioritize problems: relieve pressure on the cord immediately to restore fetal oxygenation—this is the priority above all else.
Determine next steps: use a gloved hand to lift the presenting part off the cord, place the client in knee-chest or Trendelenburg, give oxygen, call for help, and prepare for an emergency cesarean; keep the hand in place until delivery and do not attempt to push the cord back. Monitor the FHR continuously.

NCLEX High-Yield Review

What the NCLEX Wants You to Know

Assess the FHR immediately after membranes rupture (rule out cord prolapse)
Cord prolapse: relieve pressure (knee-chest/lift presenting part), don't replace the cord
FHR 110–160 with moderate variability/accelerations = reassuring
Late decels = act (LION); tachysystole = stop oxytocin
Track labor by dilation/effacement/station; the uterus must relax between contractions

Frequently tested findings: FHR patterns (VEAL CHOP), cord prolapse, tachysystole, cervical progress (dilation/effacement/station), and ROM assessment. Expected vs unexpected: regular contractions with rest between, a normal FHR with variability/accelerations, and clear fluid are expected; late/prolonged decels, a prolapsed cord, meconium fluid, tachysystole, or heavy bleeding are emergencies. Priority assessments: FHR/fetal status, contraction pattern/resting tone, labor progress, and ROM (cord/fluid). Delegation: the RN assesses the cervix/FHR/contractions and manages emergencies; UAP can take maternal vitals, help with positioning/comfort, and report—but not perform or interpret fetal/labor assessments. Safety: assess FHR after ROM, respond to late decels/cord prolapse, stop oxytocin for tachysystole, and keep the uterus relaxing between contractions. Common traps: not checking the FHR after ROM, pushing a prolapsed cord back, continuing oxytocin during tachysystole, and missing meconium/abnormal fluid.

Memory Aids

Labor factors "5 P's": Passenger, Passageway, Powers, Position, Psyche.
Stages "1-2-3-4": 1 = Dilation (0→10 cm), 2 = Pushing/birth, 3 = Placenta, 4 = Recovery (watch bleeding).
FHR patterns "VEAL CHOP": Variable=Cord, Early=Head, Accelerations=Okay, Late=Placental insufficiency.
Late decels action "LION": Left side, IV fluids up, Oxygen, Notify (stop oxytocin).
After ROM "COAT": Color, Odor, Amount, Time — and assess the FHR first (cord prolapse).
Cord prolapse "Lift & drop": lift the presenting part off the cord and drop the hips (knee-chest/Trendelenburg); don't replace the cord.

Case Study

Ms. Rivera, 24, is in active labor at 6 cm / 90% / 0 station, receiving oxytocin. The nurse notes the contractions are now occurring every 1½ minutes with little rest between them (about 7 in 10 minutes), and the fetal monitor shows late decelerations with decreasing variability.

Recognize & analyze cues

Cues: uterine tachysystole (>5 contractions/10 min with inadequate rest) on oxytocin, plus late decelerations and decreasing variability = the uterus isn't relaxing enough for the placenta to re-oxygenate the fetus → fetal hypoxia/distress.

Prioritize problems

Priority: restore fetal oxygenation by reducing the excessive contractions and improving placental perfusion—this is urgent.

Determine next steps

Stop the oxytocin infusion, reposition to the left side, give oxygen (non-rebreather), increase IV fluids, and notify the provider (consider a tocolytic like terbutaline per order). Continue continuous fetal monitoring and reassess.

Evaluate

Success = contractions space out with adequate rest, and the FHR recovers to a normal baseline with moderate variability and no late decelerations. Document the pattern, interventions, and fetal response with times.

Practice Questions

Answer choices are numbered; the correct answer is given as a number.

1. A client's membranes rupture during labor. What is the nurse's first action?

Document the time of rupture
Assess the fetal heart rate
Change the bed linens
Notify the provider that the water broke

Rationale

Answer: 2. The first action after rupture of membranes is to assess the fetal heart rate—a sudden drop can indicate cord prolapse. Documentation (1), linen change (3), and notification (4) come after ensuring fetal well-being.

2. The nurse notes late decelerations on the fetal monitor. Which set of actions is appropriate?

Increase the oxytocin and place the client supine
Continue monitoring and document only
Encourage vigorous pushing
Reposition to the left side, give oxygen, increase IV fluids, and stop the oxytocin

Rationale

Answer: 4. Late decelerations indicate placental insufficiency—the intrauterine resuscitation measures ("LION") are left side, oxygen, increase IV fluids, and stop oxytocin, then notify. Increasing oxytocin/supine (1), documenting only (2), and pushing (3) worsen fetal oxygenation.

3. A laboring client is documented as "10 cm, 100%, +2." What does this indicate?

Labor has not yet started
The cervix is only partially dilated
The cervix is fully dilated and effaced with the fetal head descending—delivery is near
The fetus is in a breech position

Rationale

Answer: 3. 10 cm = complete dilation, 100% = complete effacement, +2 = the presenting part is 2 cm below the ischial spines—the client is in second stage and delivery is near. The other options misinterpret the findings.

4. During a vaginal exam after rupture of membranes, the nurse feels a pulsating cord. What is the priority action?

Reposition to relieve cord pressure (knee-chest or Trendelenburg) and lift the presenting part off the cord
Gently push the cord back into the uterus
Have the client walk to speed up labor
Continue the cervical exam to check dilation

Rationale

Answer: 1. A pulsating cord = cord prolapse. The priority is to relieve pressure on the cord—reposition (knee-chest/Trendelenburg) and lift the presenting part off the cord with a gloved hand, give oxygen, call for help, and prepare for emergency cesarean. Never push the cord back in (2); ambulation (3) and continuing the exam (4) are dangerous.

5. Which fetal heart-rate finding is considered reassuring?

A baseline of 100 bpm
Absent variability with late decelerations
A baseline of 140 bpm with moderate variability and accelerations
Recurrent variable decelerations to 80 bpm

Rationale

Answer: 3. A baseline of 110–160 bpm with moderate variability and accelerations is reassuring (a well-oxygenated fetus). Bradycardia (1), absent variability with late decels (2), and recurrent variable decels (4) are non-reassuring.

6. SATA. Which findings during labor require immediate nursing action? Select all that apply.

A palpable, pulsating cord in the vagina after rupture of membranes
Late decelerations with decreasing variability
Contractions every 3 minutes with good resting tone between them
More than 5 contractions in 10 minutes with no rest between (tachysystole)
Green, meconium-stained amniotic fluid

Rationale

Answers: 1, 2, 4, 5. A prolapsed cord, late decels, tachysystole, and meconium fluid are non-reassuring/emergent. Contractions every 3 minutes with good resting tone (3) are a normal, reassuring labor pattern.

7. SATA. Which components does the nurse assess when evaluating uterine contractions? Select all that apply.

Frequency (start of one to the start of the next)
Duration (beginning to end of a contraction)
Intensity (mild, moderate, strong)
The mother's blood type
Resting tone (relaxation between contractions)

Rationale

Answers: 1, 2, 3, 5. Frequency, duration, intensity, and resting tone describe contractions. The mother's blood type (4) is important history but is not a component of contraction assessment.

8. Priority. A nurse is caring for four laboring clients. Which client should the nurse assess first?

A client at 4 cm with contractions every 5 minutes and a normal FHR
A client requesting an epidural
A client whose water just broke with a normal FHR and clear fluid
A client with a sudden fetal heart-rate drop and a palpable cord after rupture of membranes

Rationale

Answer: 4. A sudden FHR drop with a palpable cord after ROM indicates cord prolapse—a life-threatening emergency and the priority. The others are stable or routine.

Key Takeaways

Track labor by dilation (0→10 cm), effacement (0→100%), and station (−5→+5), assess contractions (frequency/duration/intensity/resting tone), and identify the stage of labor; labor is shaped by the 5 P's.
Assess the fetal heart rate immediately after membranes rupture—a sudden drop suggests cord prolapse; note the fluid's color, odor, amount, and time.
Cord prolapse is an emergency: relieve cord pressure (knee-chest/Trendelenburg, lift the presenting part), give oxygen, call for help, prepare for cesarean—never push the cord back.
FHR 110–160 with moderate variability and accelerations = reassuring; read patterns with VEAL CHOP. Late decels → act with LION (left side, IV fluids, oxygen, notify/stop oxytocin).
The uterus must relax between contractions; tachysystole (>5/10 min or no rest) → stop oxytocin and resuscitate the fetus.
Recognize meconium-stained fluid, bleeding, and imminent delivery (crowning) and respond appropriately.
Document cervical status, contractions, FHR pattern, ROM details, and interventions by time; act promptly on non-reassuring signs.
