1

Attitude

Relationship of fetal parts to one another

2

Dilation

Progressive opening of the diameter of the cervical os

3

Effacement

Progressive thinning and shortening of the cervix

4

Engagement

Fixation of the fetal presenting part into the true maternal pelvis

5

Fetal Lie

Relationship of the long axis of the fetus to the long axis of the mother

6

Presentation

Fetal body part that enters the maternal pelvis first

7

Station

Relationship of the presenting part to the ischial spine

8

Vertex

Top or crown of fetal head

9

Four types of maternal pelves

  • Gynecoid * good
  • Anthropoid * good
  • Android
  • Platypelloid

10

Identify theroies of onset of normal labor

  • Hormonal Influences: changes in estrogen to progesterone ratio
  • Prostaglandin secretion: Prepares the uterus to respond to oxytocin
  • Development of oxytocin receptors
  • Fetal cortisol
  • Uterine irritability secondary to stretching and pressure near term

11

Impending signs of labor

  1. Lightening
  2. Braxton-Hicks Contractions
  3. Bloody show
  4. Energy Spurt

12

Lightening

Movement of the fetus downward into the pelvic cavity (engagement)

13

Braxton-Hicks Contactions

Mild, intermittent, contractions that occur throughout pregnancy

14

Bloody Show

Pink-tinged mucous secretions resulting from cervical dilation

15

Energy Spurt

Sudden increase in energy; also called nesting

16

What factors distinguish tru labor from false labor?

True labor has

  1. Contractions are consistently increasingin frequency, duration, and intensity and tend to increase with walking. They begin in the lower back and gradually sweep around to lower abdomen
  2. Discomfort may persist as back pain in somewomen and often resembles menstrual cramps during early labor
  3. Cervical Change (caused by contractions) includes progressive effacement and dilation
  4. Possible ROM

 

False Labor:

  • Contractions are inconsistent in frequency, duration, and intensity and do not change or may decrease with activity
  • Discomfort is felt in the abdomen and groin...feels annoying more than painful
  • Cervix does not significantly change in effacement or dilation

17

Four primary sources of pain during labor

  1. Tissue ischemia
  2. Cervical dilation
  3. Pressure on pelvic structures
  4. Vaginal and perineal distention

18

What is the most accurate assessment for labor progress?

Progressive cervical effacement and dilation

19

Purpose and description of leopold's maneuver's during labor

To determine and presentation and position of the fetus and aid in location of fetal heart sounds

  1. Palpate uterine fundus to distinguish if the breech or head is at the uterine fundus
  2. Palpate each side of the uterus to determine which side the back is on
  3. Palpate the suprapubic area to confirm the presentation determined in the first maneuver. Attempt to grasp the presenting part gently between the thumb and fingers, if not engaged, the presenting part will move upward in the uterus
  4. Only if cephalic - Slide hands on the bottom sides of the uterus to determine if the head is flexed or extended (prominence felt on opposite side of fetal back)

20

Priority nursing responsibilities for spontaneous rupture of membranes

  1. Assess Fetal HR
  2. Color
  3. Odor
  4. Amount
  5. Time of Rupture

21

Duration of second stage of labor for primipara

53-57 minutes without an epidural, 79 minutes with an epidural

22

Sterile Vaginal Exam (SVE)

Used to assess labor progress

  1. Fetal presentation/position
  2. Cervical effacement/dilation
  3. Station
  4. Integrity of Rupture of Membranes

23

Duration of second stage of labor for the multipara

17-19 minutes without an epidural, 45 minutes with an epidural
