17
Q

shoulder

A

c-section; fetus is a transverse lie

18
Q

engagement

A

when largest diameter of the presenting part is in the pelvic inlet

19
Q

station

A

relationship of presenting part of ischial spines

20
Q

fetal position

A

relationship of presenting part landmarks to maternal pelvis

21
Q

baby is engaged at…

A

at level station 0 (ishial spine)

22
Q

engaged baby

A

The biparietal diameter (B P D) of the fetal head is in the inlet of the pelvis. In most instances, the presenting part (occiput) will be at the level of the ischial spines (0 station) - babies head cannot be pushed away

23
Q

ischial spine is at ____ station

A

zero

24
Q

fetal position

A

occiput - back of head
mentum- chin
sacrum - butt
acromino - shoulde r

25
Q

anterior landmark

A

babies bakc is going ot be facing moms betlly

26
Q

posterior landmark

A

babys back is going to be towards moms back (back to back) – well have to reach far back to feel occiput

27
Q

presentation

A

is the fetal body part entering the pelvis first

28
Q

position

A

is the relationship of presenting part landmarks to maternal pelvis

29
Q

3 phases of contractions

A

increment, acme, decrement

30
Q

contraction are measured in mm Hg using…

A

IUPC - to see if contractions are strong enough

intrauterine pressure catheter

31
Q

labor usually begins when

A

between 38-42 weeks gestation

no full understanding of cause of labor

32
Q

effacement

A

drawing up of cervix; Occurs from longitudinal traction of cervix with contractions and Cervix goes from thick to paper thin (described in %)

33
Q

dilation

A

opening up cervix; Uterus elongates and straightens fetal body and pushes baby/amniotic sac against cervix –> this causes cervix to open (up to 10cm)

34
Q

Effacement of the Cervix in the Primigravida (1)

A

At the beginning of labor, there is no cervical effacement or dilatation. The fetal head is cushioned by amniotic fluid.

35
Q

Effacement of the Cervix in the Primigravida (2)

A

Beginning cervical effacement: As the cervix begins to efface, more amniotic fluid collects below the fetal head.

36
Q

Effacement of the Cervix in the Primigravida (3)

A

Cervix is about one-half (50%) effaced and slightly dilated. The increasing amount of amniotic fluid below the fetal head exerts hydrostatic pressure on the cervix.

37
Q

Effacement of the Cervix in the Primigravida (4)

A

Complete effacement and dilatation.

38
Q

why do we need to know what time woman’s water broke

A

infection

39
Q

main difference b/w true and false labor

A

in true labor, after walking around for awhile there IS PROGRESS SOME CHANGE

40
Q

true labor

A
  • Regular UCs
  • UCs get closer
  • UCs longer/harder
  • Pain radiates
  • More intense with walking
  • No decrease in UCs w/ bath & rest
  • Progressive cervical changes!
41
Q

false labor

A
  • Irregular UCs
  • Not closer
  • Not longer/harder
  • Pain in abdomen
  • No effect or decrease intensity with walking
  • Rest & bath eases UCs

-No cervical changes
