56
What are the soft tissues
lower uterine segment, cervix, pelvic floor muscles, vagina & introitus
57
the uterus becomes... ( once birth begins)
very muscular so that it can push against the cervix
58
To allow the first fetal position to descend into vagina....
the cervix (effaces) thins & dilates opens)
59
what is efface
thin (happens first)
60
what is dilate
opens (happens after)
61
what is the pelvic floor
muscular layer that separates pelvic cavity from perineal space below & helps rotate fetus
62
the soft tissues ...
develope throughout pregnancy until the vagina can dilate to accommodate fetus
63
what are the 2 types of powers
involuntary & voluntary
64
What are the primary powers?
involuntary contractions that originate from certain pace maker points in upper uterine muscles
they move downward in waves, separated by short rests
65
How are primary powers described?
1) Freq. (from beginning of one to the beginning of next one)
2) Duration ( length of contraction
3) Intensity (strength of contraction @ peak)
66
What are the primary powers responsible for?
Effacement- shortening/ thinning of cervix
| this usually happens before dilation
67
facts about dilation
- goes from <1 cm to 10cm.
- can't be palpated when fully dilated
- marks end of 1st labour stage
- due to pressure AND hormones
68
Are uterine contractions independent or dependent of external forces
uterine contractions are independent of external forces
| -may reduce if given narcotics which can cause prolonged labour
69
When do the secondary powers begin
As soon as the presenting part reaches the pelvic floor
70
What are the secondary powers contractions like?
explosive- involuntary urge to push
| -bearing down efforts: contracts diaphragm & abs
71
What is the result of secondary powers?
intra-abdominal pressure
72
do secondary powers have an effect on dilation?
No
73
Are frequent positions changes good or bad
good
74
what are the benefits of position change
reduce fatigue
increase comfort
increase circulation
75
What are the benefits of upright birth
- gravity promotes descent
- contractions are stronger & more effective in dilating cervix
- labour is shorter
- improves blood flow
- pressure on vena cava reduce
76
If the woman wants to lie down...
lateral ( on side) is best
77
benefits of all 4's birth

2) surge of energy (nesting)
or diarrhea, nausea, vomit & indigestion
3) return of frequent urination
82
is there a single cause of labour?
no there is no single cause
- hormones
- distention of uterus & pressure
- result in strong, regular rhythmic contractions
83
What are the stages of labour
1) regular progression of uterine contractions
2) Effacement & progressive dilation of cervix
3) progress in descent of presenting part
84
Describe stage one of labour
- last onset of regular uterine contractions to full dilation of the cervix
- longest stage
- can take 1-18hr
- 2 phases: -latent (early)
- active labour - quicker dilation & descent
85
Describe stage two of labour
- fully dilated to brith
- latent (passive)
- active (urge to push stretch receptors)
86
describe stage three of labour
birth of fetus - birth of placenta
| 3-5 mins or an hour
87
Describe stage four of labour
2hr after placenta
| recovery, bonding & breastfeed
88
What are the mechanisms of labour
- engagement
- descent
- flexion
- internal rotation
- extensions
- restitution & external rotation
- expulsion
89
What is meant by engagement
- when the biparietal diameter of head passes pelvic inlet
| - in nulliparas - this occurs b4 active labour
90
what is asyclitsm
- head is deflected in pelvis
- head is positioned so that it cannot descend
- this is an error in engagement
91
what is meant by the descent
- progression through the pelvis by 4 forces
- slow & steady in first baby
- Rapid in second baby
92
What are the 4 forces that determines descent
1) pressure via amniotic fluid
2) direct pressure exerted by contracting fundus on fetus
3) force of contraction of diaphragm & abs
4) extension & straighten fetal body
93
why does the head flex into the chest
to produce a smaller diameter
94
what is internal rotation
head must rotate in order to exit
95
what is extension
the head emerges vis extension
| the occiput, then face, then chin
96
what is restitution & external rotation
after the head is born , baby rotates to position it was in, in inlet (restitution)
the anterior shoulder will descend first
97
what is expulsion
trunk is born by flexing laterally
98
fetal heart rate?

- pain can be avoided in childbirth
- pain in childbirth indicates sin
- pain can be managed by a women
115
muiltiparas base their expectations on...
their last birth & may only voice their concerns when asked
116

- explain things in detail
- let woman know that there aren't any expectations
- explain the role of the nurse
- encourage the woman to trust her ability to give birth
- acknowledge that the support person may also feel stressed
- be sensitive to needs
118
how to better accommodate LGBTQ+ labour
- transmen can give birth (biologically female)
- ask how they describe their gender identity
- document their gender identity & pronoun
- best if met before birth to plan
- ask permission to touch
119
indigenous birth is a....
family event & community - the hospital vistitor limit may effect this
120
what questions should you ask to provide culturally safe care during labour
- value/ meaning of childbirth
- view of wellness or sickness of childbirth

124
what is the postpartum involution process of the uterus
it means to return to non-pregnant state
125
when does involution begin
immediately after explosion of placenta with contraction of uterus
126
where is the uterus at the end of the 3rd stage of labour
- uterus midline
- 2cm above from umbilicus

500 g
134
after 2 weeks the uterus weighs
350g
135
after 6 weeks the uterus weighs
60-80g
136
why does the uterus grow?

- hypertrophy & hyperplasia
- pressure from baby inside
137
what is autolysis
self destruction of hypertrophied tissue (AKA happens to uterus)
138
will the uterus ever be the same size again?
no due to extra cells it'll be a tiny bit bigger
139
what is sub-involution
failure for uterus to return to size
140
what are common causes of sub-involution
placental fragments
| infection
141
how is postpartum hemostasis achieved
mostly be compression of intramometrial blood vessels as uterine muscles contract & not as much clot formation
***oxytocin coordinates these contractions
142
why are woman often give oxytocin after birth of placenta
to make sure that uterus contracts so that they won't lose blood
143
what does breastfeeding do to oxytocin
increased it & decreases likely hood to hemorrhage
144
what are afterpains & who are they experienced by
- Uterus firm in 1st mothers (only mild cramps)
| - vigorous contractions in subsequent pregnancies (more pain) (breastfeeding & oxytocin will make these pains worse)
145
what is placental sight
post-partum vascular constriction & thromboses
| an upward growth of endometrium that causes sloughing of dead tissues
146
what does placental sight do
prevents scaring of womb so it can function again
147
when is endometrial regeneration completed by
day 16 (except placenta site) (w6)
148
what is lochia
post-birth vaginal discharge
149
what is lochia rubra
bright red with clots (first 2hr)
- like a heavy period but it's a steady decreased
- its blood a trophoblastic waste
150
what is lochia serosa
- pink/brown (starts 3-4 days after) (22-27 days long)
| - old blood, rum, WBC, & debris
151
what is lochia alba
- starts 10 days after
- yellowish white
- WBC, decidua, epithelial, serum, mucus, bacteria
- can go on for 4-8 weeks
152
common facts about lochia
- less in cesarean
- blood gushes when walk
- persistent bleeding can mean a fragmented placenta
- 10-15% of ppl will have serosa at week 6
- endometriosis can be the cause if there is still serosa at week 4-5 with pain & fever
- an offensive odour means infection
153
what would indicate non local bleeding
- if it spurts out
| - could be cervical or vaginal tear
154
characteristics of the cervix after birth
- soft
- the ectocervix is bruised
- gradually closes but id edamtous, thin & fragile several days after birth
155
how dilated is the cervix after day 2 post partum
2-3cm
| a week = 1 cm
156
does the cervix go back to the way it was?
no it never regains its pre pregnant appearance
157
postpartum estrogen deprivation causes
1) thinness of mucosa
2) absence of rugae
3) vagina is drier
158
Does the vagina go back to the way it was?
no it never completely regains it's prepregnat tone
| the reggae reappear after 3 weeks but aren't as prominent
159
what is a scared hymen called
a myrtiform carnuckles
160
postpartum the introitus is
erythematous & edematous but after 2 weeks i looks just like a nullipara if lacerations are carefully prepared, good hygiene & hematoma treated
161
what to know about healing an episteotomy
- signs of infection
- any loss of approximation
- 2-3 w to 4-6 months for complete heal
162
when will hemorrhoids decrease size by
6 weeks
163
how long will it take for pelvic floor muscles to regain strength
- may take 6 months
| - kegels are encouraged
164
how long for abdominal wall to relax after birth
```
2 weeks (still has pregnant appearance)
within 6 weeks it'll look almost preprgnant
```
165
what are the factors that determine if you regain ur muscle tone
- previous tone
- proper exercise
- adipose
166
what happens to hormones when the placenta leaves
decreased hormones
- diuresis of extra cellular fluid due to decreased estrogen
- woman who don't breast-fed regain estrogen quicker
- HCG will disappear 3-4 weeks after
167
what happens to prolactin
rises throughout pregnancy
even more @ birth (highest first month after)
remains high if breast feeding continues
determined by: - freq. duration & degree of supplementary feeding
-in non-breast feeding woman prolactin will go back to normal within a week
168
when will ovulation occur?
- in lactating women it'll occur within 6 months b/c prolactin suppresses ovulation
- in non lactating women: 27 days (7-9 weeks ) (70% by week 12)
- 1st flow after birth quite heavy (3-4 cycles & it'll be back to normal)
169
what happens to the urinary system postpartum urinary system

back to normal within a month
-dilation of ureters & hypotonia (6w to normal)
-can persist for 3 months ( increased risk for UTI)
170
what are the important facts about urine components
glycosuria is gone by 1 week
lactosuria may occur in lactating women
blood urea nitrogen b/c autolysis of involuting uterus
protein uria will resolve in 6 weeks
ketonuria happens with women of prolonged labour & dehydration
171
what happens to do with partpartum fluid loss
-within 12 hr, begin to lose excess tissue fluid
-profuse diaphoresis occurs for 2-3 days b/c of low estrogen, removal of increased venous pressure & loss of pregnancy induced fluid volume
Will lose about 2.25kg of "water weight"
172
What happens to the urethra & bladder post partum
-experiance decreased urge to void due to birth induced trauma, increased bladder capacity & effects of anaesthesia, and pelvic floor soreness
173
what causes pelvic floor soreness
- forces of labour
- vagina lacerations
- episteotomy
174
if bladder is distended it causes the uterus to have...
excessive bleeding, cannot contract as well, higher risk of UTI
175
when does a postpartum women regain bladder tone?
5/7 days
176
are postpartum woman hungry or full?
HUNGRRY
177
why may bowel evacuation not occur for 2/3 days
- drecreased muscle tone of intestines
- prelabour diarrhoea
- lack of food
- dehydration
- may resist urge to defecate
* *should increase fluid & fiber
- operative births have increased risk of anal incontinence (shouldn't last more than 6mo)
- cesarean birth also may have a build up of gas
178
when does the breast milk come in
within 72-96hr
| breasts will feel warm, from & tender
179
when will engorgement go away
24-48hr
180
what happens when moms decide to not breast feed
prolactin levels will drop very quickly
engorged but will resolve within 24-36hr
milk present but shouldn't be expressed
-comfort measures: binder, bra, ice packs, pain meds
-avoid stimulating nipples
-lactation will cease in days to 1 week
181
how much blood is lost in vaginal birth
300-500ml (10%)
182
how much blood is lost during cesarean
500-100ml (15-30% )
183
when will blood plasma volume be replenished by
3rd day
184
what are the 3 major blood volume changes
1) elimination of uteroplacental circulation
2) loss of placental endocrine function removes the stimulus for vasodilation
3) mobilization of extra vascular water stored during pregnancy
185
what will happen to cardiac output postpartum
it will increase for 48hr
| then it will remain increased for 12 weeks after birth & may not stabilize until 24 weeks
186
what will happen to vital signs post partum
hr & bp will return to normal within a few days
RR will rapidly return to normal
temperature will rise b/c dehydration will resolve in a day
orthostatic hypotension for 48hr
187
what will happen to the postpartum circulation
increased WBC, increase plasmofibrinogen
| immune system is mildly suppressed but will go back to normal
188
what will happen to the postpartum respiratory system
decreased pressure
increased chest compliance
rib cage elasticity can take months to regain
stretched intercostals may never return to normal
normal metabolism by 1-2 weeks
189
in the neurological & musculoskeletal system
all changes will be revered
190
what will happen to the postpartum immune system
- melasma mask will sometimes stay
- hyper pigmentation of areolae & lineament nigra may not go away
- stretch marks will fade
- hair growth slows
- spider angiomas, palmar erethema, & elupis go away
191
how is attachment maintained
through proximity & interaction with infants as the parent becomes acquainted with the infant
identifies infant as an individual
claims infant as a family member
**THIS IS A MUTUALLY SATISFYING PROCESS
192
attachment includes mutuality
an infants behaviour elicit a corresponding set of parental behaviours
193
attachment occurs most easily when
the temperament, social characteristics, appearance & sex match characteristics
*** DISSAPOINTMENT can cause delays in attachment
194
how do parents become aquainted
by touch, eye contact, talk, & exploring
195
what is the claiming process
ID baby - terms of likeness, difference, uniqueness incorporated into fam
**CAN BE NEGATIVE OR POSITIVE
196
how do labour processes effect attachment
-long labour, drugs, breast-feed probs, premature birth, separation can all delay initial positive feelings
197
What should be known about close contact
-it facilitates attachment, affection, breastfeeding less crying, increased thermoregulation, increased cardiorespiratory stability
but isn't an essential
198
extended contact is especially good for:
those @ risk for parenting difficulties
- adolescents
- low social/ financial support
199
best ways to facilitate eye contact
enface position: 20cm apart
dim light
right after birth
200
what is etrainment
when newborn moves in time with structure of adult speech
201
what is biorhythmicity
fetus in toon with mothers natural rhythms such a heartbeat
| infant musst establish own through routine and consistent learning & care
202
what is reciprocity
behaviour that provides the observer with clues to respond to cues
203
what is synchrony
the fit between the infants cues & parents response
204
describe transition to parenthood
```
time of disorder & satisfiaction
normal coping may not work
may become unsupportive
the transition is harder on the father
limited knowledge
```
205
what are the phases to becoming a mother
1) dependent ( taking in phase)
2) dependent- independent phase (taking hold)
3) Interdependent (letting go phase)
206
what happens in the mothers dependent phase of motherhood
first 1-2 days
-focus on self& basic needs
excited
207
what happens in the motherhood dependent - independent stage
2-3 days lasts 10day-2 week
-focus is the care of baby
this is optimal teaching time
208
what happens in the motherhood interdependent phase
Focus is forward as a family
| reassertion of relationship with partner
209
4 stages of becoming a mother
1) commitment, attachment to unborn baby & prep
2) Acquaintance/ attachment for infant, learning care (2-6 weeks)
3) moving ward new normal
4) achievement of maternal identity through redefining self (4m)
210
Maternal sensitivity to needs deremines the relationship
awareness, affect, timing, perception, flexibility, acceptance, responsivensss to cutes
211
mothers may feel overwhelmed for
3-6 mo
212
plan additional supportive consoling for
- 1st time mom
-in experienced with child care
carreer provided stimulation
lack friends or fam
adolescent
213
What are the phases to become a father
- Expectations + intentions (desire for emotional involvement)
- confronting reality (deal w/ expectations - frustration, disappointment, guilt, helpless)
- creating role of father (alter expectations, refine role, learn to care & struggle for recognition)
- Reaping rewards (smile, meaning 6w-2 mo)
214
what happens to fathers first 4-10 weeks
- uncertin
- increased responsibility
- bad sleep
- re-establish relationship with partner
215
common adjustment issue for couples
- changes in relationship
- division of household & infant duties
- finance
- balance
- social activities
216
was to cope for couples
- share expectations & assess relationships
- date nights
- appreciation
- be flexible
217
what are the factors of changes in woman sexuality
- hormone shift
- increased breast size
- body not pre-preg yet
- fatigue
- exhaustion
