Maternal-Newborn

Prenatal labs, stages of labor, Bishop score, Apgar scoring, and postpartum assessment using BUBBLE-HE.

Essential Prenatal Labs

TestTimingPurpose
Blood type, Rh, antibody screenFirst visitIdentify Rh incompatibility; give RhoGAM at 28 weeks and within 72 hours postpartum if Rh-negative mother with Rh-positive infant
CBCFirst visit, 28 weeksAssess for anemia (Hgb < 11 g/dL in pregnancy)
Rubella titerFirst visitNon-immune: vaccinate postpartum (live vaccine — not during pregnancy); avoid pregnancy for 1 month after
Hepatitis B surface antigenFirst visitIf positive: newborn gets HepB vaccine + HBIG within 12 hours of birth
HIV screeningFirst visitIf positive: antiretroviral therapy to reduce vertical transmission
GBS culture35–37 weeksIf positive: IV penicillin during labor (give ≥ 4 hours before delivery)
1-hour glucose challenge24–28 weeksScreening for gestational diabetes (≥ 140 mg/dL → 3-hour GTT)
Quad screen15–20 weeksAFP, hCG, estriol, inhibin-A. Screens for trisomy 21, 18, neural tube defects

Stages of Labor

StagePhaseCervical DilationContractionsNursing Care
Stage 1 (Onset of true labor to complete dilation)Latent (Early)0 – 6 cmMild, q5–30 min, 30–45 secEncourage ambulation, rest, hydration; talkative/excited patient
Active6 – 8 cmModerate, q3–5 min, 40–60 secBreathing techniques, position changes, pain management; focused patient
Transition8 – 10 cmStrong, q2–3 min, 60–90 secMost intense phase; nausea/vomiting common; provide support, coaching; patient may feel loss of control
Stage 2 (Complete dilation to delivery of baby)10 cm (complete)Urge to pushPush with contractions; monitor FHR; prepare for delivery. Primipara: up to 2–3 hrs; Multipara: up to 1–2 hrs
Stage 3 (Delivery of baby to delivery of placenta)Mild crampingSigns of placental separation: gush of blood, cord lengthening, globular uterus. Usually 5–30 min. Inspect placenta for completeness (3 vessels: 2 arteries, 1 vein)
Stage 4 (First 1–2 hours postpartum)Monitor VS q15 min, fundal checks, lochia, bladder, bonding. Highest risk for hemorrhage

Bishop Score

Used to assess cervical readiness for induction. Score ≥ 8 = favorable for induction.

Apgar Score

Assessed at 1 minute (transition) and 5 minutes (adaptation) after birth. Score 0–2 for each category.

Sign012
Appearance (Color)Blue/pale all overPink body, blue extremities (acrocyanosis)Completely pink

Activity (Muscle Tone)Limp/flaccidSome flexionActive motion
RespirationsAbsentSlow, irregular, weak cryGood cry, regular respirations
  • 7–10: Normal
  • 4–6: Moderate difficulty; stimulation, O2 may be needed
  • 0–3: Severe distress; immediate resuscitation

Postpartum Assessment: BUBBLE-HE

LetterAssessmentKey Points
BBreastsSoft, filling, engorged? Nipple condition. Colostrum present (days 1–3), transitional milk (days 3–5)
UUterus (Fundus)Firm, midline, at or below umbilicus. Should descend ~1 fingerbreadth/day. Boggy = massage; displaced = full bladder
BBladderShould void within 6–8 hrs postpartum. Full bladder displaces uterus → hemorrhage risk
BBowelAssess bowel sounds, flatus, BM. Stool softeners PRN; may take 2–3 days
LLochiaRubra (red, days 1–3) → Serosa (pinkish, days 4–10) → Alba (white/yellow, 10 days – 6 weeks). Foul smell = infection. Clots > golf ball = report
EEpisiotomy/PerineumAssess using REEDA: Redness, Edema, Ecchymosis, Discharge, Approximation. Ice first 24 hrs, then sitz baths
HHoman's sign / Hemorrhoids / HemoglobinAssess for DVT risk (calf pain, swelling); hemorrhoids common; check H/H for blood loss
EEmotional StatusBaby blues (days 2–3, resolves in 2 weeks) vs postpartum depression (persists > 2 weeks, impaired function). Screen with Edinburgh scale
