Memory tricks

Proven mnemonics — fast to learn, hard to forget.

Stages of Labor
Labor stages: 1st (cervical dilation 0–10 cm), 2nd (pushing, delivery), 3rd (placenta), 4th (recovery, first 1–4 hrs postpartum).
Stages of Labor
Four stages every OB nurse must know β€” with the key assessments for each
First stage: latent (0–6 cm, irregular contractions), active (6–10 cm, stronger/closer contractions), transition (8–10 cm, most intense). Assess: cervical dilation, effacement, station, fetal heart rate, contractions. Second stage: complete dilation to birth. Push with contractions (closed glottis). Monitor fetal heart rate. Third stage: placenta delivery β€” within 30 minutes. Signs of separation: gush of blood, lengthening of cord, uterine fundus rises and becomes firm. Fourth stage: first 1–4 hours after delivery. Assess: fundus (firm, midline, at umbilicus), lochia, perineum, BP, HR. Most common time for postpartum hemorrhage.
1st stage
0–10 cm dilation
2nd stage
Pushing β€” delivery of baby
3rd stage
Placenta delivery β€” <30 min
4th stage
First 1–4 hrs β€” hemorrhage risk
Fetal Heart Rate Patterns
FHR decelerations: Early (head compression β€” normal), Variable (cord compression β€” change position), Late (uteroplacental insufficiency β€” EMERGENCY).
Fetal Heart Rate Decelerations
Three deceleration patterns β€” one is normal, one needs repositioning, one is an emergency
Early decelerations: mirror contractions (start and end together), caused by head compression, normal β€” no intervention needed. Variable decelerations: abrupt drop, variable timing, caused by cord compression. Intervention: change maternal position (left lateral, knee-chest), O2, stop oxytocin, fluid bolus β€” may need amnioinfusion. Late decelerations: begin AFTER peak of contraction, caused by uteroplacental insufficiency (placenta not delivering enough O2 to fetus). EMERGENCY β€” notify provider immediately. Interventions: left lateral position, O2 10 L nonrebreather, stop oxytocin, IV fluid bolus, prepare for delivery. Persistent late decels = C-section.
Early
Head compression β€” mirror contraction, NORMAL
Variable
Cord compression β€” reposition, O2
Late
Uteroplacental insufficiency β€” EMERGENCY
Postpartum Hemorrhage
PPH: blood loss >500 mL vaginal, >1000 mL C-section. 4 Ts: Tone (uterine atony #1), Trauma, Tissue, Thrombin.
Postpartum Hemorrhage
The leading cause of maternal mortality β€” recognizing and responding to PPH
Most common cause: uterine atony (boggy uterus = not contracting). 4 Ts: Tone (70–80% β€” uterine atony), Trauma (lacerations), Tissue (retained placenta), Thrombin (coagulopathy). Assessment: fundus (boggy? midline? above umbilicus?), lochia (saturating pad in <1 hour = abnormal), vital signs (tachycardia first sign, then hypotension). Management of atony: massage fundus (never pummel), bimanual compression, oxytocin (Pitocin), methergine (not in HTN), carboprost (not in asthma), Bakri balloon, blood products. Monitor: I&O, H&H, coagulation studies.
Tone
Uterine atony β€” most common cause
Trauma
Lacerations
Tissue
Retained placenta
Thrombin
Coagulopathy
Preeclampsia
Preeclampsia: BP β‰₯140/90 after 20 weeks + proteinuria. Severe: BP β‰₯160/110, HELLP syndrome, seizure (eclampsia) = EMERGENCY.
Preeclampsia and Eclampsia
The hypertensive disorder of pregnancy that can progress to life-threatening eclampsia
Preeclampsia: onset >20 weeks gestation. Criteria: BP β‰₯140/90 on two occasions 4 hrs apart, plus proteinuria. Severe features: BP β‰₯160/110, platelets <100,000, creatinine >1.1, LFTs 2Γ— normal, pulmonary edema, severe headache, visual disturbances, RUQ pain. HELLP syndrome: Hemolysis, Elevated Liver enzymes, Low Platelets. Nursing: quiet, dim room (reduce stimuli), magnesium sulfate (seizure prophylaxis AND treatment β€” monitor for toxicity: absent DTRs, RR <12, urine <25 mL/hr), antidote = calcium gluconate. Eclampsia: grand mal seizure β€” give magnesium, protect from injury, O2, notify provider immediately. Delivery is the only cure.

Newborn Assessment
Normal newborn: HR 120–160, RR 30–60, Temp 36.5–37.5Β°C. Acrocyanosis normal. Caput succedaneum vs cephalohematoma.
Newborn Assessment
Key normal newborn findings β€” and the abnormalities that require intervention
Normal vitals: HR 120–160 (tachycardia if >160, bradycardia if <100), RR 30–60 (normal is fast!), Temp 36.5–37.5Β°C (axillary). Acrocyanosis: blue hands/feet normal for first few hours (peripheral circulation immature) β€” central cyanosis (lips, trunk) = abnormal. Caput succedaneum: edema crossing suture lines, present at birth, resolves in days. Cephalohematoma: bleeding under periosteum, does NOT cross suture lines, appears 24–48 hrs, resolves in weeks (risk for jaundice). Vernix (white coating), lanugo (fine hair), milia (white dots on nose) = all normal. Meconium: first stool within 24–48 hrs. Void within 24 hrs.
HR
120–160 bpm normal
RR
30–60 β€” fast is normal
Acrocyanosis
Blue hands/feet β€” normal
Caput
Crosses suture lines β€” resolves fast
Cephalohematoma
Does NOT cross suture lines β€” jaundice risk
Breastfeeding
Breastfeeding: latch = areola in mouth, not just nipple. Feed 8–12 times/24 hrs. Signs of adequate feeding: 6+ wet diapers/day by day 4.
Breastfeeding Support
NCLEX-tested breastfeeding education β€” latch, frequency, and signs of adequate intake
Good latch: baby's mouth covers areola (not just nipple), lips flanged outward, chin touching breast, audible swallowing, no pain. Feed on demand β€” 8–12 times per 24 hours (every 2–3 hrs). Duration: 10–15 min per breast. Signs of adequate intake: 6+ wet diapers/day by day 4, weight regain by day 10–14 (lose up to 10% initially), yellow seedy stools by day 4. Colostrum: first 3–5 days β€” high in antibodies (IgA), thick yellow, small amounts normal. Engorgement: frequent feeding, warm compress before feeding, cold compress after, supportive bra. Mastitis: breast infection β€” continue breastfeeding, antibiotics, warm compress, rest.
C-Section Nursing Care
Post C-section: assess uterine fundus, incision, lochia, pain, Foley output. Ambulate early (12–24 hrs) to prevent DVT.
Cesarean Section Nursing
Post-operative care after C-section β€” combining OB and surgical nursing care
Immediate post-op: assess as for any surgical patient PLUS obstetric assessments. Fundus: firm, midline, at umbilicus. Lochia: rubra (red, first 3 days), serosa (pink, days 4–10), alba (white, days 11+). Incision: Pfannenstiel (bikini line β€” horizontal). Foley catheter: usually removed 12–24 hrs post-op. Pain: multimodal analgesia β€” IV opioids β†’ oral NSAIDS + acetaminophen β†’ wean opioids. Early ambulation: 12–24 hrs β€” prevents DVT, ileus, pneumonia. Sequential compression devices (SCDs) until ambulating. Patient teaching: no driving for 4–6 weeks, lift nothing heavier than baby, incision care. Next delivery: VBAC possible for some.
Gestational Diabetes
GDM: diabetes diagnosed during pregnancy. Risks: macrosomia, hypoglycemia in newborn, shoulder dystocia, Cesarean delivery.
Gestational Diabetes
The metabolic complication of pregnancy β€” risks for mother and baby both tested on NCLEX
GDM: glucose intolerance first recognized during pregnancy. Screening: 24–28 weeks (1-hr glucose challenge test). Diagnosis: 3-hr OGTT. Pathophysiology: placental hormones β†’ insulin resistance. Risks to baby: macrosomia (large baby β†’ difficult delivery, shoulder dystocia), neonatal hypoglycemia (baby was compensating for mom's high glucose β†’ baby's insulin remains high after birth β€” check newborn glucose at 1 hr). Risks to mother: UTIs, preeclampsia, C-section, future Type 2 DM (50% risk). Management: diet first (complex carbs, small meals), exercise, insulin if needed (NOT oral antidiabetics in pregnancy). Resolves after delivery.
Macrosomia
Large baby β€” shoulder dystocia risk
Newborn hypoglycemia
Check glucose at 1 hr
Management
Diet β†’ exercise β†’ insulin
Future risk
50% develop Type 2 DM
Newborn Jaundice
Physiologic jaundice: appears day 2–3, resolves by day 7–10. Pathologic: appears <24 hrs = EMERGENCY. Treatment: phototherapy.
Newborn Jaundice
The most common newborn condition β€” distinguishing physiologic from pathologic is key
Jaundice: yellow skin from bilirubin (RBC breakdown). Physiologic (normal): appears day 2–3 (after 24 hrs), peaks day 3–5, resolves day 7–10. Cause: immature liver, polycythemia. Pathologic (abnormal): appears within first 24 hours β€” Rh or ABO incompatibility, infection. EMERGENCY β€” needs immediate treatment. Phototherapy (bili lights): converts bilirubin to water-soluble form excreted in urine/stool. Nursing: eye shields (protect from light), turn every 2 hrs, increase feeds (hydration promotes excretion), monitor skin color and bilirubin levels, remove briefly for feeds. Kernicterus: bilirubin deposits in brain β†’ permanent neurological damage.
Physiologic
Day 2–3, resolves day 7–10 β€” normal
Pathologic
<24 hrs β€” EMERGENCY, incompatibility
Phototherapy
Eye shields, turn q2h, increase feeds
Kernicterus
Bilirubin in brain β†’ brain damage
Contraception
Most effective: implant > IUD > sterilization. Least effective: spermicide. Estrogen contraindicated: smokers >35, HTN, DVT history.
Contraception Nursing
Effectiveness rates and contraindications β€” the NCLEX expects nurses to counsel appropriately
Effectiveness (best to least): Implant (Nexplanon, >99%), IUD (Mirena/Paraguard, >99%), Sterilization (>99%), Depo-Provera shot (94%), Combined pill (91% typical use), Patch/Ring, Male condom (85% typical), Diaphragm (83% typical), Spermicide (72% typical). Estrogen-containing contraceptives CONTRAINDICATED in: smokers β‰₯35 years (DVT/PE risk), uncontrolled HTN, history of DVT/PE/stroke, breast cancer, migraines with aura, breastfeeding <6 weeks. Progestin-only (mini-pill, Depo, Mirena, Nexplanon): safer alternatives. Copper IUD (Paraguard): no hormones, also emergency contraception within 5 days.
Postpartum Assessment β€” BUBBLE-HE
BUBBLE-HE: Breasts, Uterus, Bladder, Bowel, Lochia, Episiotomy/Edema, Homans sign, Emotional.
Breasts Β· Uterus Β· Bladder Β· Bowel Β· Lochia Β· Episiotomy Β· Homans Β· Emotional
The complete postpartum assessment β€” check every shift in the right order
Breasts: engorgement, nipple condition, signs of mastitis (red, warm, flu-like). Uterus: fundus firm (boggy = atony β†’ massage), midline (deviated = full bladder), descends 1 cm/day, at umbilicus day 1. Bladder: void within 4–6 hrs of delivery, distension displaces uterus β†’ hemorrhage risk. Bowel: bowel sounds present, first BM by day 2–3 (may be painful). Lochia: Rubra (red, days 1–3), Serosa (pink, days 4–10), Alba (white, days 11–14+). Report: foul odor, heavy saturation, large clots. Episiotomy: REEDA (Redness, Edema, Ecchymosis, Discharge, Approximation). Homans sign: calf pain with dorsiflexion (DVT β€” limited reliability). Emotional: baby blues vs postpartum depression (>2 weeks, affects functioning).
