Quick answer: The highest-yield NCLEX maternity topics are preeclampsia (new BP ≥140/90 after 20 weeks with proteinuria or end-organ signs; magnesium sulfate prevents seizures, calcium gluconate reverses magnesium toxicity), fetal heart rate decelerations (VEAL CHOP; stop any oxytocin infusion first for late decelerations), postpartum hemorrhage (most often uterine atony, so fundal massage first), the laterally displaced fundus of a full bladder, and APGAR scoring at 1 and 5 minutes.
This maternity and OB review walks you through the high-yield content the NCLEX tests across the full childbearing cycle: prenatal danger signs and preeclampsia, fetal heart rate monitoring and labor emergencies, postpartum assessment and hemorrhage, and newborn APGAR scoring. Use it to lock in normal-versus-abnormal findings and the correct order of nursing interventions.
Key takeaways
- Preeclampsia’s severe warning signs are severe headache, visual changes, and epigastric or right upper quadrant pain; magnesium sulfate prevents seizures, and calcium gluconate is the antidote for magnesium toxicity (absent DTRs, respiratory depression, RR <12).
- Use VEAL CHOP for fetal heart rate decelerations: Variable = Cord, Early = Head, Accelerations = OK, Late = Placental insufficiency.
- Late decelerations signal uteroplacental insufficiency — when oxytocin is running, the first action is always to stop it, then reposition left lateral, give IV fluids, and notify the provider (traditional NCLEX bundles add O₂, though ACOG has de-emphasized routine maternal O₂).
- A boggy fundus means atony → massage; a fundus displaced laterally means a full bladder → have the client void or catheterize. The interventions are completely different.
- Postpartum hemorrhage (blood loss >1,000 mL) is most often from uterine atony; treat in order — fundal massage, oxytocin, methylergonovine (avoid in hypertension), carboprost (avoid in asthma), then surgery.
- APGAR is scored at 1 and 5 minutes; 7-10 is normal, 4-6 is moderate depression, and 0-3 requires immediate resuscitation.
Prenatal — The High-Yield Topics
Danger Signs in Pregnancy
These require immediate provider notification:
- Vaginal bleeding at any gestational age — placenta previa (painless) vs abruption (painful, rigid abdomen)
- Severe headache + visual changes + epigastric or right upper quadrant pain — preeclampsia severe warning signs
- BP ≥140/90 after 20 weeks — gestational hypertension or preeclampsia
- Rupture of membranes before 37 weeks — preterm PROM
- Decreased fetal movement — fewer than 10 kicks in 2 hours
- Gush of fluid from vagina — ruptured membranes (assess for cord prolapse)
Preeclampsia — Know This Cold
| Feature | Preeclampsia | Severe Preeclampsia / HELLP |
|---|---|---|
| BP | ≥140/90 on two occasions | ≥160/110 |
| Proteinuria | ≥300 mg/24h, protein/creatinine ratio ≥0.3, or dipstick 2+ (only if quantitative testing is unavailable). Not required for diagnosis — new-onset hypertension after 20 weeks plus thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, or new headache/visual changes also diagnoses preeclampsia. | Often higher, but the amount of protein does not grade severity |
| Symptoms | May be asymptomatic | Headache, visual changes, epigastric pain, hyperreflexia |
| Labs | Elevated uric acid, creatinine | HELLP: ↑LDH, ↑AST/ALT, ↓Platelets <100,000 |
| Treatment | Close monitoring, delivery if >37 wks | Magnesium sulfate (seizure prevention) + delivery |
| Antidote | Calcium gluconate (for magnesium toxicity: absent DTRs, respiratory depression, RR <12) | |
Intrapartum — Labor and Delivery
Fetal Heart Rate Monitoring
| Pattern | What It Looks Like | What It Means | Action |
|---|---|---|---|
| Early decelerations | Mirror contractions (decel starts and ends with contraction) | Head compression — normal, benign | No intervention needed. Document. |
| Variable decelerations | Abrupt drops, V or W shaped, variable timing | Cord compression | Reposition mother, O₂, amnioinfusion if recurrent |
| Late decelerations | Start after contraction peaks, gradual onset | Uteroplacental insufficiency — the baby is not getting enough O₂ | Stop oxytocin (if infusing), left lateral position, IV fluids, notify provider (O₂ is a traditional NCLEX step, but ACOG no longer recommends it routinely). This is Category II/III — non-reassuring |
| Prolonged deceleration | Decel lasting >2 min but <10 min | Cord prolapse, abruption, uterine rupture | Emergency intervention. Prepare for C-section |
Memory aid: VEAL CHOP — Variable = Cord, Early = Head, Accelerations = OK, Late = Placental insufficiency.
Show answer & rationale
(A) Increasing IV fluids improves maternal hydration and placental perfusion, and is appropriate — but it does not address the direct cause (oxytocin-driven tachysystole). Stopping the offending agent takes priority over supportive measures.
(C) Preparing for C-section may become necessary if the pattern does not resolve after intrauterine resuscitation, but it is not the first action. The first steps are always the least invasive interventions that address the cause.
(D) Left (not right) lateral positioning improves uterine blood flow by relieving vena cava compression. Right lateral is less effective. But even correct repositioning comes after stopping the oxytocin, because the hyperstimulation is the primary problem.
Key concept: Late decelerations = uteroplacental insufficiency. When oxytocin is running, the first action is always to stop it. Intrauterine resuscitation sequence: stop oxytocin → reposition left lateral → IV fluid bolus → notify provider (traditional NCLEX bundles add O₂; ACOG has de-emphasized routine maternal O₂).
Postpartum — The First 24 Hours
Normal vs Abnormal Findings
| Assessment | Normal | Abnormal — Intervene |
|---|---|---|
| Fundus | Firm, midline, at or below umbilicus | Boggy (atony) → massage. Displaced to the side → full bladder → assist to void; catheterize if unable |
| Lochia | Rubra (red, 1-3 days) → Serosa (pink, 4-10 days) → Alba (white, 10+ days) | Foul odor (infection), return to rubra from serosa (retained products), saturating pad in <1 hour (hemorrhage) |
| Vital signs | Pulse normal or slow (postpartum bradycardia is common); BP near baseline, brief orthostatic dizziness possible. Temp ≤100.4°F in first 24h (dehydration) | Temp >100.4°F after 24 hours (infection). Tachycardia + hypotension (hemorrhage) |
| Perineum | Mild edema, intact repair if episiotomy/laceration | Hematoma (unilateral swelling, severe pain), signs of infection (redness, purulent drainage) |
| Breasts | Colostrum days 1-3, milk “comes in” days 3-5, engorgement resolves with feeding | Red, hot, tender area (mastitis — continue breastfeeding + antibiotics) |
Postpartum Hemorrhage
Defined as blood loss >1,000 mL or signs of hypovolemia. The #1 cause is uterine atony (the uterus does not contract).
Interventions in order: Fundal massage → Oxytocin (Pitocin) → Methylergonovine (Methergine — contraindicated in hypertension) → Carboprost (Hemabate — contraindicated in asthma) → Surgical intervention if pharmacologic methods fail.
Newborn Assessment — The First Hour
APGAR Scoring
| Sign | 0 | 1 | 2 |
|---|---|---|---|
| Appearance (color) | Blue/pale all over | Pink body, blue extremities (acrocyanosis) | Completely pink |
| Pulse | Absent | <100 bpm | ≥100 bpm |
| Grimace (reflex) | No response | Grimace | Cry, cough, sneeze |
| Activity (tone) | Limp | Some flexion | Active movement |
| Respiration | Absent | Slow, irregular | Strong cry |
Scored at 1 and 5 minutes to document the newborn’s condition and response to any interventions; resuscitation is never delayed to wait for the 1-minute score. Score 7-10 = normal. 4-6 = moderate depression, stimulate and assess. 0-3 = severe, immediate resuscitation. For a deeper breakdown of newborn scoring plus the GTPAL pregnancy history system, see our APGAR and GTPAL scoring guide.
Show answer & rationale
(A) Massaging the fundus is indicated for a boggy (soft, non-contracted) uterus. This fundus is firm. Massaging a firm fundus is unnecessary and painful.
(C) Notifying the provider is not needed for a full bladder. This is an independent nursing intervention — empty the bladder and reassess. The fundus should return to midline at or below the umbilicus after voiding.
(B) Oxytocin is used for uterine atony. The uterus is firm, so it is contracting appropriately. The elevation and displacement are caused by the bladder, not the uterus.
Key concept: Fundus displaced laterally = full bladder. Fundus boggy = atony → massage. Know the difference — the NCLEX tests this frequently and the interventions are completely different.

Frequently Asked Questions
What is the classic preeclampsia triad?
The three warning symptoms are a severe headache, visual changes, and epigastric or right upper quadrant pain. They are ACOG severe features rather than a diagnostic triad — the older classic triad of hypertension, proteinuria, and edema has been retired. Combined with a BP of ≥140/90 after 20 weeks, they point toward preeclampsia; proteinuria supports the diagnosis but is not required when other severe features are present. Severe features are read disjunctively: a BP of ≥160/110 or any one of these symptoms is enough to classify the preeclampsia as severe, and magnesium sulfate is given to prevent seizures. Hyperreflexia is a classic bedside sign of CNS irritability and is worth reporting, but it is not one of ACOG’s diagnostic severe features.
What does VEAL CHOP mean in fetal heart rate monitoring?
VEAL CHOP pairs each deceleration pattern with its cause: Variable decelerations = Cord compression, Early decelerations = Head compression, Accelerations = OK (reassuring), and Late decelerations = Placental insufficiency. Early decelerations are benign, but late decelerations are non-reassuring and require intervention.
What is the first nursing action for late decelerations during an oxytocin infusion?
Stop the oxytocin. Late decelerations indicate uteroplacental insufficiency, and oxytocin-driven tachysystole reduces placental blood flow, so removing the cause comes first. After that, the intrauterine resuscitation sequence is: reposition to the left lateral position, give an IV fluid bolus, and notify the provider. Traditional NCLEX bundles also add O₂, although ACOG has de-emphasized routine maternal oxygen for these tracings.
How do I tell uterine atony apart from a full bladder postpartum?
Check the fundus. A boggy (soft) fundus means atony, and the response is to massage it. A firm fundus that is above the umbilicus and displaced to one side means a full bladder is pushing the uterus up and laterally, so have the client void or catheterize. The fundus should return to midline at or below the umbilicus after the bladder is emptied.
How is the APGAR score used and what do the numbers mean?
APGAR assesses Appearance, Pulse, Grimace, Activity, and Respiration, each scored 0 to 2, at 1 and 5 minutes to document the newborn’s condition and response to any interventions (resuscitation is never delayed to wait for the score). A score of 7-10 is normal, 4-6 indicates moderate depression requiring stimulation and assessment, and 0-3 calls for immediate resuscitation.
