Fetus drops in pelvis (decreased fundal height)

Question 13

Ballottement

Answer 13

Passive movement of fetus

Question 14

Best for labor

Question 20

Types of pelvis shapes

Answer 20

1. Gynecoid
2. Android
3. Anthropoid
4. Platypelloid

Question 21

Gynecoid

Answer 21

50% round pelvis- conducive to vaginal birth

Question 22

Android

Answer 22

23% heart shaped- uncommon vaginal birth C- section likely

Question 23

Anthropoid

Answer 23

24% vertical oval- vaginal birth possible but not likely

Question 24

Platypelloid

Answer 24

3% horizontal oval- vaginal birth not ideal but possible

Question 25

Primary forces of labor

Answer 25

Dilatation Effacement Descent Contractions

Question 26

Dilatation

Answer 26

Cervix opens to 10 cm

Question 27

Effacement

Answer 27

Cervix thins to piece of paper- 0% is fully effaced

Question 28

Descent

Answer 28

Station of fetus

Question 29

Contractions

Answer 29

Frequency- beginning to beginning Intensity- palpate fundus or measure w/ IUPC Nose- mild chin- moderate forehead- strong to very strong Duration- length of contraction

Question 30

Maternal position

Answer 30

Do not lay flat on back- baby can suppress vena cava Side- lying is usually moms favorite Upright squatting with squat bar can be good for "op"

Question 31

Secondary forces of labor

Answer 31

Bearing down urge

Question 32

Possible causes of labor onset

Answer 32

``` Progesterone Estrogen Fetal Cortisol Prostaglandin Oxytocin Uterine Distention ```

Question 33

Signs of labor onset

Answer 33

``` Lightening Cervical changes- best objective measure Bloody show Rupture of membranes Sudden burst of energy ```

Question 34

True labor

Answer 34

~Contractions are regular intervals; become more frequent; more intense; and last longer over time ~intensity usually increases with walking ~progressive cervical dilatation and Effacement ~loss of mucous plug = water break

Question 35

False labor

Answer 35

~Irregular contractions and no change in frequency intensity or length ~walking has no effect or lessens contractions ~no cervical change ~May lose mucous plug

Question 36

Stages of labor

Answer 36

1st- beginning of true labor until complete cervical dilatation 2nd- complete dilatation to birth of baby -baby is born 3rd- delivery of baby to delivery of placenta -placenta delivered 4th- first four hours postpartum

Question 37

Stage 1 of labor

Answer 37

Three phases: 1. Latent phase- 0-3cm 2. Active phase- 4-7cm 3. Transition phase- 8-10cm

Question 38

Cardinal movements (must be in order)

Answer 38

1. Engagement 2. Descent 3. Flexion 4. Internal rotation 5. Extension 6. External rotation (restition) 7. Expulsion
