  26. A patients current pregnancy is counted as a
  27. How to calculate  EDD
    LMP + 7 days - 3 months

    Look at the year
  28. Explain Leopold's maneuver regarding positioning of the fetus
    Tells location and presentation of the fetus

    it is a systemic method for palpating the fetus thru the abdominal wall during the latter part of the pregnancy.
  29. When is Leopolds maneuver done?
    during admission to figure out where to put the FHR monitor
  30. Fetal Lie
    the orientation of the long axis of the fetus to the long axis of the woman

    Longitudinal-vertical, either head or butt is in the pelvis parallel to mom

    Transverse-long axis of the fetus is at right angles to mom, perpendicular to mom

    Oblique-some angle btwn longitudinal and transverse
  31. Fetal position
    the location of a fixed reference point on the presenting part in relation to the 4 quadrants of the maternal pelvis

    • right/left
    • anterior/posterior
  32. Attitude
    normal is flexion, with the head and arms and legs flexed tightly against the trunk

    chin presentation
  36. Sacrum
    breech presentation
  37. Occiput
    cephalic presentation
  38. Dilation
    how wide the cervix has opened up and it is measured in cm's
  39. How does the cervix dilate?
    as the cervix is pulled upward and the fetus us pushed downward it is pushed open
  40. Effacement
    the thinning and softening of the cervix and it is measured in %
  41. How does effacement occur?
    Labor contractions push the fetus downward against the cervix and the cervix pulls upward.  This will cause it to become shorter and thinner as it is drawn over the fetus and amniotic sac
  42. How do you figure out the baby's station?
    The ischial spine is the marker and is at "0".

    above the ischial spine it is -1,-2,-3 (farthest pt)

    below the ischial spine it is +1,+2,+3 (hello baby)
  43. What does fetal monitoring tell us?
    how the baby is doing hemodynamically and with O2
  44. 3 things fetal monitoring keeps track of
    • timing of contractions
    • HR
    • fetal response in relation to stress of contractions
  45. What do contractions do to the fetus?
    with each contraction blood flow thru the uterus slows, if the contraction is strong enough all blood flow will stop and if it is for too long it can cause stress on the baby
  46. Prolonged FHR lower than this can impair brain and heart perfusion
  47. A persistent FHR faster than this decreases cardiac output due to inadequate ventricular filling time
  48. 2 ways to monitor uterine activity (contractions)
    • TOCO transducer (external)
    • IUPC (internal)
  49. What does a TOCO pick up?  What does it look like?
    • maternal movement
    • fetal movement

    uterine contractions look like a bell shape, other movements look like spikes
  50. Where do you place the TOCO?
    over the fundus
  51. Rules of applying a IUPC
    it is internal and measures intra-amniotic pressure.

    • dilated to 2-3cm
    • ruptured membranes
  52. How do you apply an external fetal heart rate monitor?
    it is applied to the maternal abdomen with the transducer over the fetus back for best recording
  53. What does a FHR monitor reflect?
    fetal oxygenation status
  54. How do you apply an internal FHR monitor?
    electrodes are put on the fetus scalp which allows for direct tracing of the HR
  55. Rules of putting on an internal FHR monitor
    • dilated to 2-3 cm
    • ruptured membranes
    • put on the scalp....but avoid the face, fontanelles and genitalia
  56. Baseline FHR
    assessed btwn contractions

    • avg rate for 10 minutes ranges from
    • 110-160bpm
  57. Bradycardia FHR
    FHR baseline is below 110bpm OR

    decreased from previous baseline rate by 20bpm for at least 10 minutes
  58. Tachycardia FHR
    FHR baseline is above 160bpm or increased from previous baseline rate by 20bpm for at least 10 min
  59. Sinusodial FHR
    wave like appearance, alternating small accelerations and decelerations centering around the baseline
  60. When will you see sinusoidal FHR
    in severely anemic fetus and requires immediate attention
  61. What do abrupt decelerations look like?
    V shaped
  62. What do late decelerations look like?
    • they begin after the contraction begins
    • the lowest point is after the peak of the contraction
    • recovery occurs after the contraction has ended
  63. Describe Early Decelerations
    • mirrors the contraction
    • lowest point is at the peak of the contraction
    • recovery is by the end of the contraction
  64. What causes early decelerations?
    head compression...the fetal head is descending in to the pelvic cavity
  65. What causes early decelerations?
    head compression against the mom's pelvis or cervix
  66. How long should decelerations last?
  67. What causes late decelerations?
    fetus is experiencing hypoxia from decreased utero-placental perfusion
  68. What causes utero-placental insufficiency?
    late decelerations= hypoxia
  69. What causes variable decelerations?
    umbilical cord compression
