Q

Why does blood flow to the placenta decreases during a contraction?

A

*the muscle fibers of the uterus constrict around the maternal spiral arteries, which supply the placenta
*there is a relative increase in the woman’s blood volume
*this temporary change increases her blood pressure slightly an slower her pulse rate

25
What may occur if the laboring woman lies on her back during labor?
supine hypotension
26
Why is the laboring woman encouraged to rest in positions other than supine during labor?
it promotes blood return to her heart and decreases the risk for supine hypotension
27
What may occur during rapid, deep breathing of labor?
hyperventilation
28
What may occur as the laboring mother exhales too much carbon dioxide (hyperventilation)?
respiratory alkalosis
29
What may the laboring mother feel if she is hyperventilating (in resp. alkalosis)?
tingling of her hands & feet; numbness and dizziness
30
What should the nurse do if the laboring mother is hyperventilating?
help her slow her breathing; breath into a paper bag or cupped hands to restore normal blood levels of carbon dioxide and relieve symptoms
31
A reduction in gastric motility can affect a laboring client resulting in what?
n/v
32
What is commonly provided to laboring mothers experiencing n/v during labor?
ice chips; small amounts of other clear liquids may be allowed; solid foods are usually withheld to prevent vomiting and aspiration if general anesthesia is required.
33
A full bladder can inhibit what in a laboring client?
fetal descent
34
Why can a full bladder inhibit fetal descent?
occupies space in the pelvis ; increases risk of bladder hypotonia and infection
35
Most research suggests that there is how much normal blood loss for a vaginal delivery?
500 to 1000mL
36
Elevated levels of several clotting factors (esp. fibrinogen) during pregnancy and continue to be higher during labor and after delivery increase what for the client?
can provide protection from hemorrhage yet it increases the mother's risk for a venous thrombosis during pregnancy and after birth
37
The exchange of oxygen, nutrients, and waste products through what system?
placental circulation
38
When does most placental exchange occur?
during the interval between contractions
39
Fetal intolerance to the stress of labor causes their HR to be what?
110- 160 bpm
40
In the fetal pulmonary system, the lungs produce what to allow normal development of the airways?
fluid
41
Four major factors interact during normal childbirth (4Ps)
Power Passage Passenger Psyche
42
Primary force that moves the fetus through the maternal pelvis
uterine contractions
43
Woman feels an urge to push and bear down as the fetus distends her vagina and puts pressure on her rectum
maternal pushing efforts
44
During the 1st stage of labor
uterine contractions- onset to full cervical dilation
45
During the 2nd stage of labor
pushing efforts- full cervical dilation to birth of the baby
46
usually more important to the outcome of labor than the soft tissue
the bony pelvis
47
What do not readily yield to the forces of labor?
bones and joints
48
pelvic brim
the linea terminalis
49
what divides the bony pelvis
the linea terminalis
50
Where is the false pelvis located?
(top) above linea terminalis
51
Where is the true pelvis located?
(bottom) below linea terminalis
52
The 3 subdivisions of the true pelvis
*Inlet *midpelvis *outlet
53
Who is the passenger?
fetus, membranes, and placenta
54
Several fetal anatomic and positional variables influence what?
the course of labor
55
Components of the birth fetal head
*Bones *Sutures *Fontanels
56
Bones of the fetus head
-2 frontal bones on the forehead -2 parietal bones at the crown of the head -1 occipital bone at the back of the head
56
Sutures of the fetal head
Narrow areas of flexible tissue that connect fetal skull bones
57
Fontanels of the fetal head
-Wider spaces at the intersections of the sutures connecting the skull hones -Anterior fontanel diamond shape -Posterior fontanel triangular shape
58
The fetus enters the birth canal in what presentation?
cephalic
59
At what percentage does the fetus enter the birth canal in the cephalic presentation?
96- 97% of the time
60
What serves as key landmarks for assessing fetal position and head flexion during vaginal exams?
the sutures and fontanels
61
What enables the fetal head to mold and adjust to the pelvis's shape?
sutures and fontanels
62
the orientation of the long axis (spine) of the fetus to the long axis (spine) of the woman client
fetal lie
63
In more than 99% of pregnancies, the lie is longitudinal and parallel to the what of the woman?
long axis (spine)
64
relationship of fetal body parts to one another
attitude
65
normal attitude
flexion
66
Presentation examples
*Cephalic vertex, military, brow, face *Breech frank, full, footling *Shoulder
67
the fetal part that first enters the pelvis and termed the presenting part
presentation
68
The most common presentation?
the cephalic presentation with the fetal head flexed
69
Other presentations besides the cephalic are associated with what?
associated with prolonged labor and are more likely to require caesarean birth
70
location of fixed reference point on the presenting part in relation to the four quadrants of the maternal pelvis
location
71
Position references
*Right or Left *Occiput (O) Mentum (M) Sacrum (S) *Anterior (A) Posterior (P) *Transverse (T)
72
The 4 Ps are an interrelated what?
whole
73
Factors that appear to have a role in starting labor
1.) progesterone levels fall 2.) increase release of prostaglandins 3.) Increased secretion of natural oxytocin 4.) Increased oxytocin receptors in the uterus 5.) Fetal membrane release prostaglandins 6.) Cortisol secreted by fetal adrenal glands 7.) Increased stretching and pressure of the uterus and cervix
74
When does labor normally start?
when the fetus is mature enough to adjust easily to extrauterine life but after it grows so large that vaginal birth is impossible
75
Normal Labor: Premonitory Signs
*Braxton Hicks contractions *Lightening *Increased vaginal mucus secretion *cervical changes (softening, possible dilation, bloody show) *energy spurt and weight loss
76
true labor
*increased contractions; tend to increase with walking *increased discomfort; lower back; resembles menstrual cramps *cervical change; progressive effacement and dilation most important
77
false labor
*contractions inconsistent; decrease with activity (walking) *discomfort is felt in the abdomen and groin an can be annoying *cervix does not change
78
movement of fetus through the birth canal
descent
79
fetal presenting part reaches 0 station
engagement
80
Normal Labor: Labor Mechanisms
1.) Descent 2.) Engagement 3.) Flexion 4.) Internal rotation 5.) Extension 6.) External rotation 7.) Expulsion
81
the mechanism of labor that accompanies all the others; without it none of the mechanisms will occur
descent
82
occurs when the largest diameter of the fetal presenting part (normally cephalic) has passed the pelvic inlet and entered the pelvic cavity
engagement
83
the fetal head is flexed farther as it meets resistance from the soft tissues of the pelvis; presents the smallest anteroposterior diameter to the pelvis
flexion
84
allows the largest fetal head diameter to align with the largest pelvic diameter
internal rotation
85
of the fetal head as the neck pivots on the inner margin of the symphysis pubis, allowing the head to align with the curves of the pelvis outlet
extension
86
of the fetal head, aligning the head with the shoulders during expulsion
external rotation
87
the fetal shoulders and fetal body exit the pelvis- birth canal
expulsion
88
1st stage of labor
-latent phase -active phase
89
How many phases of labor is there?
4
90
labor duration varies significantly between first time mothers and whom?
experienced mothers
91
first time mothers & experienced mothers may have...
fast labor
92
1st stage of labor this position is ideal for pushing because it enlarges the pelvic outlet slightly and adds the force of gravity to the client's efforts
squatting
93
positions of labor
-standing -lunge -abdominal left and tuck -counter-pressure -sitting/ squatting -side lying with peanut ball
94
allowing uterine contractions to cause most of the fetal internal rotation and descent after full dilation
laboring down
95
lower extremity nerve injury
LENI
96
What is the goal of maternity care?
To protect the health of the mother, fetus, and newborn while enhancing the birth experience.
97
What does technology do in the birth experience?
aids in identifying and addressing issues quickly but can make care feel impersonal
