Maternity emergencies
NCLEX maternity emergencies: preeclampsia and magnesium safety, postpartum hemorrhage by fundal findings, and labor complications including cord prolapse and tachysystole.
Maternity emergencies are pattern recognition under time pressure: which blood pressure and neuro cues mean seizure risk, which fundus picture means which hemorrhage action, and which labor event needs the oxytocin stopped or the presenting part lifted off the cord.
Preeclampsia: when it turns severe
Preeclampsia is new hypertension in pregnancy with end-organ risk. The exam cares whether you can spot severe features and start seizure protection before you tidy every lab.
| Usually not the emergency | Severe / report-now |
|---|---|
| Mild ankle edema that eases with rest | Facial and hand swelling with headache or visual changes |
| 2+ reflexes without clonus; gradual weight gain | Hyperreflexia with clonus; BP at or above **160/110** |
| Reassuring fetal heart rate alone | RUQ or epigastric pain; platelets under **100,000**; rising liver enzymes |
Exact antihypertensive drug choice and BP notify cutoffs follow facility protocol and obstetric orders. On the exam, treat severe-range BP plus cerebral or hepatic cues as the priority cluster.
Magnesium sulfate
Magnesium is for seizure prophylaxis, not as a primary blood-pressure drug. Keep the room quiet, use seizure precautions, and keep calcium gluconate ready as the antidote.
| Improving on magnesium | Toxicity — act now |
|---|---|
| Urine output rising (e.g. toward 30–40+ mL/hr as ordered) | Oliguria / falling urine output |
| Reflexes present but settling; calmer sensorium | Absent deep tendon reflexes |
| Respiratory rate recovering into the mid-teens | Respirations under **12**, falling LOC |
- Stop the magnesium infusion.
- Support airway and breathing.
- Give calcium gluconate as ordered.
- Notify the provider and continue close monitoring.
Safety
During an eclamptic seizure: turn side-lying, protect from injury, keep the airway open. Do not restrain the client or put anything in the mouth.
HELLP
Hemolysis, Elevated Liver enzymes, Low Platelets — often with right-upper-quadrant pain in a client who already has preeclampsia. This is an obstetric emergency pathway, not a “watch overnight” finding.
Postpartum hemorrhage: read the fundus
Young clients can keep a near-normal blood pressure while soaking pads. Believe the pad, clots, and fundus, not a reassuring cuff alone. A pad soaked in about 15 minutes, clots larger than a golf ball, or a soft enlarged uterus are abnormal; afterpains, a one-time gush on standing, and one pad over several hours can be expected.
| Fundus / bleeding picture | Likely cause | First moves |
|---|---|---|
| Boggy, often displaced (full bladder) | Uterine atony (most common) | Fundal massage, empty the bladder, oxytocin / uterotonics as ordered |
| Firm midline fundus, bright ongoing bleeding | Laceration (or retained tissue) | Do not keep massaging forever — inspect, notify, prepare repair / evacuation |
| Firm fundus, heavy bleeding, no obvious source | Coagulopathy | Escalate, labs, blood products per protocol |
| Bleeding lightens then returns red with clots; uterus boggy/enlarged | Retained placental fragments | Notify; anticipate exam / evacuation |
| Unrelieved unilateral perineal pain, firm fundus, rising pulse | Concealed hematoma | Notify; do not dismiss as “normal swelling” |
- Support the lower uterus during massage so you do not invert the uterus.
- Methylergonovine: avoid in hypertension; it is not a rapid IV-push drug.
- Escalate to second-line uterotonics, IV access, crossmatch, and surgical help if the uterus stays boggy.
Labor: true vs false, then the emergencies
| True labor | False labor / Braxton Hicks |
|---|---|
| Regular contractions that get stronger and closer | Irregular tightening |
| Persists with walking; back-to-front discomfort | Eases with rest or activity change |
| Produces cervical change | No progressive dilation/effacement |
Transition (about 8–10 cm) brings intense, frequent contractions, an urge to push, and irritability. That is expected late first-stage behavior, not by itself a hemorrhage cue.
Membranes rupture and cord prolapse
- Check the fetal heart rate first after rupture (cord prolapse risk).
- If the cord is felt or seen: call for help immediately.
- Relieve pressure: lift the presenting part off the cord; place knee-chest or Trendelenburg.
- Do not push the cord back in. Keep it moist per protocol and prepare for emergency birth.
Oxytocin tachysystole and previa
- Contractions too frequent with late decelerations: stop oxytocin first, then side-lying, oxygen and IV fluid bolus as ordered, notify.
- Placenta previa (painless bright red bleeding): no vaginal exam. Monitor the fetus, start IV access, estimate blood loss, prepare for obstetric management.
FHR timing (exam shorthand)
| Pattern | Association | Nurse stance |
|---|---|---|
| Early decelerations | Head compression | Usually benign with labor progress |
| Variable decelerations | Cord compression | Reposition; relieve cord pressure if prolapsed |
| Late decelerations | Uteroplacental insufficiency | Nonreassuring — stop oxytocin if running, intrauterine resuscitation, notify |
How to reason under time pressure
- Is this severe preeclampsia or magnesium toxicity right now?
- Is the fundus boggy or firm — and does that match the bleeding?
- Did membranes just rupture — what is the FHR?
- Is oxytocin causing tachysystole with late decelerations? Stop it first.
Must know
- 1Severe preeclampsia cues: BP at or above 160/110, severe headache, visual changes, RUQ/epigastric pain, platelets under 100,000, hyperreflexia with clonus.
- 2Mild ankle edema and Braxton Hicks are not the emergency. Facial/hand swelling with headache and visual changes is.
- 3Magnesium sulfate: seizure prophylaxis. Toxicity = lost DTRs, respirations under 12, oliguria, falling LOC → stop infusion, give calcium gluconate.
- 4Eclamptic seizure: side-lying, protect from injury, keep airway open. Do not restrain or put objects in the mouth.
- 5PPH: boggy fundus = atony (massage, empty bladder, uterotonics). Firm fundus with bright bleeding = laceration. Firm with no source = think coagulopathy.
- 6Methylergonovine is contraindicated in hypertension. Do not give it as a rapid IV push.
- 7After membranes rupture: check fetal heart rate first (cord prolapse risk).
- 8Prolapsed cord: call for help, lift the presenting part off the cord, knee-chest or Trendelenburg, prepare for emergency birth.
- 9Oxytocin tachysystole with late decelerations: stop oxytocin first, then reposition, oxygen/fluids, notify.
- 10Placenta previa with painless bright red bleeding: no vaginal exam.
Memory hooks
HELLP
Hemolysis, Elevated Liver enzymes, Low Platelets — often with RUQ pain in a client with preeclampsia.
Boggy = massage; firm + bleed = look elsewhere
A soft fundus points to atony. A firm midline fundus with ongoing bright bleeding points to laceration or retained tissue, not more massage alone.
VEAL CHOP timing
Variable → Cord; Early → Head; Acceleration → OK; Late → Placental insufficiency. Act on late and unresolved variable patterns.
How it's tested
Stems stack a BP or neuro cue with a magnesium drip, a pad count with a fundal finding, or a membrane rupture with a sudden FHR drop. Distractors treat mild edema as preeclampsia, keep oxytocin running through late decelerations, massage a firm bleeding fundus, or perform a vaginal exam in previa.
