Naegele's rule

Estimated date of delivery calculated as first day of last menstrual period plus 7 days, minus 3 months, plus 1 year (280 days total).

Gravida and para

Gravida is the total number of pregnancies including the current one; para is the number of births at or beyond 20 weeks gestation.

TPAL system

Obstetric history notation: Term births, Preterm births, Abortions before 20 weeks, and Living children.

Normal fetal heart baseline

Baseline fetal heart rate between 110 and 160 beats per minute with moderate variability of 6 to 25 beats per minute.

Late deceleration

Fetal heart rate decrease that begins after the contraction peak and returns after the contraction ends, indicating uteroplacental insufficiency.

Variable deceleration

Abrupt fetal heart rate decrease of at least 15 bpm lasting at least 15 seconds, typically caused by umbilical cord compression.

Uterine tachysystole

More than five contractions in 10 minutes averaged over 30 minutes, which may impair fetal oxygenation and warrants intervention.

Preeclampsia diagnostic criteria

Blood pressure at least 140/90 after 20 weeks plus proteinuria of 300 mg/24 h or signs of organ dysfunction such as thrombocytopenia or renal impairment.

Rho(D) immune globulin timing

Given at 28 weeks gestation to Rh-negative unsensitized women and within 72 hours postpartum when the newborn is Rh-positive.

Group B Streptococcus screening

Rectovaginal culture collected at 36 0/7 to 37 6/7 weeks gestation; positive results indicate intrapartum antibiotic prophylaxis.

Gestational diabetes screening

One-hour 50-gram glucose challenge at 24 to 28 weeks; abnormal result of 140 mg/dL or higher is followed by a 3-hour diagnostic test.

Fundal height correlation

Between 20 and 36 weeks, fundal height in centimeters approximates gestational age in weeks within plus or minus 2 cm.

First stage of labor

Period from onset of labor to full cervical dilation, divided into latent phase (0–6 cm) and active phase (6–10 cm).

Second stage of labor

Interval from full cervical dilation to delivery of the newborn, during which the mother pushes with contractions.

Shoulder dystocia maneuvers

Sequence includes McRoberts position, suprapubic pressure, internal rotational maneuvers, and delivery of the posterior arm.

Postpartum hemorrhage definition

Cumulative blood loss of 1,000 mL or more, or bleeding with signs of hypovolemia within 24 hours of birth.

Uterine atony treatment

Fundal massage, bladder emptying, and uterotonics starting with oxytocin; methylergonovine is avoided in hypertensive patients.

Lochia progression

Lochia rubra (red, days 1–3), serosa (pink-brown, days 4–10), and alba (white-yellow, after day 10).

Postpartum endometritis

Fever of 38°C or higher on two of the first 10 postpartum days with uterine tenderness and foul lochia, treated with IV antibiotics.

Edinburgh Postnatal Depression Scale

Screening tool for postpartum depression; a score of 10 or higher indicates possible depression and requires further evaluation.

Mastitis management

Unilateral breast pain, redness, and fever treated with continued breastfeeding, antibiotics such as dicloxacillin, and analgesics.

APGAR scoring

Assessment at 1 and 5 minutes of Appearance, Pulse, Grimace, Activity, and Respiration, each scored 0 to 2 for a total of 10.

Newborn vital signs

Normal heart rate 110–160 bpm, respiratory rate 30–60/min, and axillary temperature 36.5–37.5°C.

Physiologic jaundice timing

Jaundice appearing after 24 hours, peaking at 3–5 days in term infants, and resolving by 1–2 weeks.

Vitamin K administration

0.5 to 1 mg intramuscularly given to all newborns within 1 hour of birth to prevent hemorrhagic disease of the newborn.

Erythromycin eye prophylaxis

0.5% ophthalmic ointment applied to both eyes within 1 hour of birth to prevent gonococcal ophthalmia neonatorum.

Newborn hypoglycemia threshold

Blood glucose below 40 mg/dL in the first 4 hours or below 45 mg/dL thereafter; symptomatic infants require IV dextrose.

Newborn weight loss

Loss of up to 7–10% of birth weight in the first week is normal; birth weight is typically regained by 2 weeks.

SBAR handoff

Standardized communication format using Situation, Background, Assessment, and Recommendation to convey patient information.

Time-out procedure

Pre-procedure pause to verify patient identity, procedure, site, and consent with the entire team before starting.

Two-patient identifier

Use of at least two identifiers, such as name and date of birth or medical record number, before any intervention.

Informed consent elements

Diagnosis, nature of procedure, risks, benefits, alternatives, and right to refuse; the provider obtains consent and the nurse witnesses.
