Between occipital and parietal bones

23
Q

Measurements of fetal skull

A

Biparietal, suboccipitobregmatic, occipitofrontal, occipitomental

24
Q

Molding of fetus head

A

Overlapping of bones of fetal head that occurs during labor by accommodation of head through birth canal

25
Q

Fetopelvic relationship

A

How fetus is aligned to be birthed

26
Q

Lie position

A

Back bones aligned

27
Q

Transverse alignment

A

Shoulder is presenting, usually from fatigued uterus

28
Q

Attitude of fetal body

A

Flexion (chin to chest, fetal position)

Extension (opposite of flexion)

29
Q

Presentations of fetus

A

Vertex- head first
Shoulder- transverse lie (usually need c section)
Breech- butt or feet coming out first

30
Q

Describing fetal position

A

Left or right side of pelvis
Occipi, mentum, sacrum, scapula (presenting part)
Anterior or posterior (facing mother or away from mother)

31
Q

Station measurement of fetal decent

A

Presenting part of head

32
Q

Station stage -3

A

Floating; above true pelvis

33
Q

Station stage -1

A

Dipping; presenting part is still in pelvis but not engaged

34

A

Engagement- level of maternal ischial spines

35

Crowning

36
Q

Positions of mother for birth

A

Sitting up is best, side lying works well, walking for first stages

37
Q

Psychological response of mother

A

Affected by tension and fear, helps being prepared and Aware,

38
Q

Mechanisms of labor

A

Accommodation of fetal anatomy to the maternal pelvis and birth canal and passage of fetus from uterus to outside world

39
Q

Engagement decent Mechanisms of labor

A

Presenting part enters true uterus

40
Q

Mechanisms of labor- decent

A

Presenting part at ischial spines

41
Q

Mechanisms of labor- flexion

A

When fetal head meets resistance from pelvis flexion of head is necessary

42
Q

Mechanisms of labor- internal rotation

A

Caused by 3 factors- pressure from contractions, curved shape of pelvis, and relationship of vertex

43
Q

Mechanisms of labor- extension

A

From pressure of uterus

44
Q

Mechanisms of labor- restitution

A

Head rotates 45 degrees a After birth of the head

45
Q

Mechanisms of labor- external rotation

A

Occurs as shoulders rotate 45 degrees

46
Q

Mechanisms of labor- expulsion

A

Birth of shoulders

47
Q

First stage of labor

A

Longest- onset to 10cm dilation

48
Q

Second stage of labor

A

From full dilation to birth of baby

49
Q

Third stage of labor

A

Birth of baby to birth of placenta

50
Q

Fourth stage of labor

A
