    Study Notes

    Obstetric Nursing Terminologies

    • Term: Expected delivery time, typically at 37 to 42 weeks of pregnancy.
    • Abortion: Termination of pregnancy before 24 weeks of gestation, can be spontaneous or induced.
    • Stillbirth: Fetus delivered with no signs of life at or after 24 weeks or weighing over 500 grams.

    Estimated Due Date

    • Estimated Date of Confinement (EDC): Average expected delivery is 280 days (40 weeks).

    Pregnancy Trimesters

    • Trimester Definition: Divided into three periods:
      • 1st Trimester: Conception to 13 weeks 6 days
      • 2nd Trimester: 14 weeks to 27 weeks 6 days
      • 3rd Trimester: 28 weeks until delivery

    Gravida and Para

    • Gravida (G): Refers to the total number of pregnancies.
    • Para/Parity (P): Number of births after 24 weeks or over 500 grams. Definitions include:
      • Nullipara (P0): No viable births.
      • Primipara (P1): One viable birth.
      • Multipara (P2+): More than one viable birth.
      • Grand multipara (P5): Five or more viable births.

    Special Categories

    • Primigravida: Pregnant for the first time.
    • Advanced Maternal Age: Pregnant at or above age 35.
    • Elderly Primigravida: First-time pregnancy at age 35 or older.
    • Multigravida: Experiencing more than one pregnancy.

    Uterus Structure and Function

    • Uterus Composition: Pear-shaped organ with three sections (fundus, corpus, cervix) and three layers (endometrium, myometrium, perimetrium).
    • Functions:
      • Supports bladder and bowel.
      • Allows fetal development.
      • Accepts and nourishes fertilized ovum.

    Cervix

    • Cervical Structure: Lower third of the uterus projecting into the vagina, containing the cervical canal.
    • Function During Pregnancy:
      • Remains closed until labor onset.
      • Provides support for the fetus.

    Vagina

    • Functions:
      • Passage for menstrual flow and sperm.
      • Barriers against infections.
      • Exit path for the fetus during delivery.

    Fetal Skull and Suture Types

    • Fetal Skull Components: Includes frontal, parietal, occipital, and temporal bones.
    • Sutures: Unossified membrane areas allowing skull shape alteration during labor.

    Vertex Presentation

    • Vertex Presentation: Fully flexed head position, ideal for cervical dilation and successful vaginal delivery.

    Molding and Edema

    • Molding of Fetal Skull: Skull shape changes occur during birth for safe passage; allows for slight bending at sutures.
    • Caput Succedaneum: Edema over the fetal head from labor pressure, heals without intervention.

    Caput Succedaneum vs. Cephalohematoma

    • Caput Succedaneum:
      • Present at birth, can cross suture lines, subsides in 24-48 hours.
    • Cephalohematoma:
      • Not present at birth, does not cross suture lines, may worsen in first 1-2 days, resolves in 4-6 weeks.

    Breast and Placenta Anatomy

    • Breast: Composed of fat, fibrous tissue, and mammary glands; influenced by increased hormone levels during pregnancy.
    • Placenta: Site for metabolic exchange between maternal and embryonic circulations, typically located in the upper uterine wall.

    Amniotic Fluid Functions

    • Maintains temperature, fluid balance, symmetric growth, fetal movement, cushioning, and umbilical cord protection.
