  1. What are the four P's of Labor and Birth
    • Powers
    • Passage
    • Passenger
    • Psyche
  2. Describe the power's phase
    forces that cause the cervix to open and that propel the fetus downward through the birth canal.

    ex. uterine contractions
  3. describe the passage phase
    bony pelvis & soft tissue

    • example
    • - false pelvis -> upper, flaring
    • - true pelvis -> lower part
  4. describe passenger
    fetus, placenta, amniotic membrane & fluid
  5. describe psyche
    mother's mental state
  6. define efface
    • thinning of the cervix
    • measured in %
  7. define dilation
    opening of the cervix
  8. 3 phases of contractions
    • increment - increase in strength
    • peak - greatest amount of strength
    • decrement - decrease in strength
  9. define frequency
    time b/w beginning of one contraction and beginning of the next
  10. define duration
    elapsed time from beginning to end of one contraction
  11. define intensity
    strength of a contraction
  12. define interval
    amount of time the uterus relaxes between contractions
  13. define suture
    strong connective tissues that separate several bones in the fetal head
  14. define fontanelle
    wider area where two sutures meet
  15. define anterior fontanelle
    diamond shaped area formed by the intersection of the frontal, sagittal, and two coronal sutures
  16. define posterior fontanelle
    triangular depression formed by the intersection of one sagittal and two lambdoid sutures
  17. when do fontanels close?
    by the time the baby is 3 months old
  18. define lie
    fetus' orientation to the mother's spine
  19. define longitudinal lie
    fetus parallel to mother's spine
  20. define transverse lie
    fetus at right angle of mother's spine
  21. define oblique lie
    fetus is b/w a longitudinal and transverse lie
  22. define occiput
    describes how the head is oriented if the fetus is in the cephallic vertex presentation
  23. define attitude
    describes the flexion of the fetus

    head flexed forward and the arms and legs flexed is normal
  24. presentation
    refers to the fetal part that enters the pelvis first
  25. vertex presentation
    head is fully flexed, most favorable
  26. military presentation
    head is neither flexed or extended
  27. brow presentation
    head is partly extended
  28. face presentation
    fetal head is fully extended and the face presents
  29. frank breech
    the fetal legs are flexed at the hips and extend toward the shoulders
  30. full or complete breech
    a reversal of the cephalic presentation, with flexion of the head and extremities
  31. footling breech
    one or both feet are present first at the cervix
  32. Signs of Impending Labor
    • braxton hicks
    • bloody show
    • increased vaginal discharge
    • weight decreased
    • nesting - increased energy
    • membrane rupture
    •   - check color & smell (should be semi clear with no odor)
  33. Define Meconium
    • first stool of the newborn
    • may be passed anytime within 12 to 24 hours
  34. Mechanisms of Labor
    • 1. descent
    • 2. engagement
    • 3. flexion
    • 4. internal rotation
    • 5. extension
    • 6. external rotation
    • 7. expulsions
  35. Stages of Labor
    • 1. Efacement & Dilation
    • 2. Expolsion of Fetus
    • 3. Expolsion of Placenta
    • 4. Recovery
  36. 3 Stages of Effacement and Dilatioin
    • Latent
    • Active
    • Transition
  37. Describe the Latent Phase
    • Cervix is dilated 1 to 4 cm
    • bloody show
    • contractions q 20 minutes
  38. Descrive the Active Phase
    • Cervix is dilated 4 to 7 cm
    • amniotic membrane rupture
    • effacement may occur
  39. Describe the Transition Phase
    • Cervce is 7 to 10 cm
    • contractions q 2 to 3 cm
  40. Define VBAC
    • vaginal birth after cesarean
    • utering scar can rupture
    • can hemorrhage
