<37 weeks gestations
2
Q
what is considered postterm
A
equal to or >42 weeks gestation
3
Q
define: labour

A
- parity
- maternal emotions
- position
- lvl of activity
- fetal size
- presentation
- position
5
Q
what is parity? how does this impact labour?
A
- number of pregnancies
- labor process is faster if have had more than one vaginal birth
6
Q
how might maternal emotions impact labor
A
- stress, anxiety, and fear cause tightness = labor may take longer
7
Q
labour includes.. (3)
A
- regular progression of uterine contractions

- descent of the presenting part
8
Q
what is the most important factor in labor management
A
- diagnoses of the active phase of 1st stage of labor
9
Q
what change occurs to the cervix in the days/weeks prior to labor to prepare for birth? why?
A
- cervix begins to soften = cervical ripening
- associated w number of hormonal shifts which are imp instigators of the labour process
10
Q
what changes occur r/t bleeding in the days/weeks prior to labor to prepare for birth?
A
- as the cervix changes, the mucus plug loosens and may be expelled fro the vagina
- this is normal, not considered antepartum bleeding
11
Q
what changes occur to the presenting part in the days/weeks prior to labor to prepare for birth?
A
- lightening = presenting part descends into true pelvis
12
Q
what contractions occur in the days/weeks prior to labor to prepare for birth?
A
- braxton hicks contractions
13
Q
what are braxton hick contractions
A
- tightening, very uncomfortable contractions in your abdomen that comes and goes
14
Q
what impact do braxton hicks contractions have on the cervix
A
- do not dilate the cervix, just part of the preparation process
15
Q
what changes occur to energy occur in the days/weeks prior to labor to prepare for birth?
A
- nesting –> surge in energy
16
Q
the onset of labor is likely due to a combo of (3)
A
- fetal hormones
- birther hormones
- progressive uterine distension and increased uterine pressure = irritability of muscle layer
17
Q
what is the hormone of labor
A
- oxytocin
18
Q
what is oxytocin produced by
A
- the posterior pituitary gland
19
Q
what role does oxytocin have in labour (3)
A
- supports the onset of labour contractions
- stimulates uterine contracions
- aids in milk let-down
20
Q
synthetic oxytocin (syntocinon) may be administered for a variety of indications such as (3)
A
- to induce labour contractions
- to augment labour contractions
- to support uterine contractions to control post partum bleeding from the placental site
21
Q
how does oxytocin play a role in supporting uterine contractions to control postpartum bleeding from the placental site
A
- stops hemorrhage by pinching blood vessels which are open after birth of placenta
22
Q
dosage of syntocinon depends on.. the dosage for induction/augmentation is greater or less than for postpartum bleeding?
A
- the timing and purpose of admin
ex. dosing for induction/augmentation is FAR less then for postpartum bleeding
23
Q
what route is used for admin of syntocinon? what determines this?
A
- IM or IV
- depends on timing, purpose
24
Q
is IV or IM syntocinon used for induction/augmentation? postpoartum bleeding?
A
- induction/augmenation = IV
- post partum bleeding = IM or IV
25
what is important to note w syntocinon
- syntocinon for induction/augmentation of labour is considered a hazardous med
26
why is synthetic oxytocin considered a hazardous med for induction/augmentation of labour
- do not want contractions increased too much d/t risk of decreased gas exchange to fetus

- may describe burning sensation during crowning due to vaginal stretching
179
what assessments should be done during the active pushing phase? (7)
- VS
- FHR and pattern
- vaginal show
- signs of fetal descent
- changes in maternal status overall (emotional status, exhaustion)
- contractions and pushing/bearing down efforts
- pain
180
how often is FHR and pattern assessed in the active pushing phase
- ongoing/every 10-15 min
181
how often is vaginal show assessed in the active pushing phase
- ongoing/q10-15 min
182
how often is overall maternal status assessed in 2nd stage of labor
- ongoing
183
how often is contractions/pushing efforts assessed in the active pushing phase
- w each effort and encourage as needed
184
how often is pain assessed in the active pushing phase
- ongoing assessments and interventions
185
why does pain occur in the 2nd stage of labour (2)
due to:
- stretching and distension of perineal tissue and the pelvic floor as baby passes thru the birth canal
- soft tissue laceration and pressure exerted on bladder, bowel, and other pelvis structures
186
how is the pain in the 2nd stage of labor described (4)
- intense
- sharp
- burning
- well-localized
187
what 3 types of pharma pain interventions used in the 2nd stage of labour
- epidural analgesia/anesthetic
- nitrous oxide
- fentanyl
188
describe nursing cate during the 2nd stage (11)
- support pushing efforts/provide encouragement
- encourage position changes/activity as needed to promote descent
- support to conserve energy/rest between contractiosn
- hydration/elimination --> is bladder full?
- hygiene --> blood, amniotic fluid, fecal matter
- pain mngmt
- emotional support
- provide info
- prepare for birth
- birth care
- provide immediate care for newborn
189
why is it imp to assess elimination during the 2nd stage of labor
- if bladder is full, it will impede birth
190
describe nursing care during the preparation for birth (3)
- communicate w HCP, charge nurse, neonatal team
- set up delivery equipment
- prepare neonatal equipment
191
what is included in nursing care during birth? (4)
- call HCP when ready for birth
- support HCP w birth
- note time of birth
- admin oxytocin if ordered w delivery of anterior shoulder
192
when does the strong urge to bear down or push become activated?
- as the presenting part puts pressure on the stretch receptors of the pelvic floor
- feeling intensified as the fetus progresses further down the birth canal
- may start to feel urge to bear down around +1 station
193
the pressure of the presenting part on the stretch receptors of the pelvic floor stimulates?? what effect does this have?
- stimulates the release of oxytocin from the posterior pituitary gland --> stimulates stronger contractions
194
describe the effect of an epidural on the urger to push
- pressure is still experienced w an epidural in place, but likely at greater lvl of descent than without
195
what should you encourage the birther to do during purshing
- encourage to listen to their body --> work w their body to push
196
pushing or bearing down efforts involve the birther...
- exerting pressure by contracting their abdominal muscles while relaxing the pelvic floor --> usually involuntary spontaneous
- often involved a strong grunt/groan by the birther as they exhale --> encourage
197
what is the benefit of working with the body during pushing (2)
- decreases fatigue
- enhances comfort
198
local anesthesia to provided to the perineum for which purpose?
- to numb the perineum just before birth to allow for episiotomy and repair of either episiotomy or laceration
199
pudendal???
200
when does the 3rd stage of lavor occur
- from time of baby's birth to delivery of the placenta
201
how long does the 3rd stage of labor las
- minutes, up to one hour --> usually 15 min
202
what are signs that the placenta is ready to delivery (5)
- cramping
- umbilical cord segment lengthens
- sudden gush of blood
- visualization of placenta at vaginal opening
- feeling pressure again
203
what is established during the 3rd stage of labour (2)
- skin to skin contact
- possibly breast/chest feeding
204
what is increased as the length of the 3rd stage increases?
- risk of hemorrhage
205
what is included in nursing care for 3rd stage of labor (4)
- pain mngmt
- education
- encourage breast/chest feeding
- encourage attachment process
206
what is included in assessments during the 3rd stage of labor
- VS
- assess for signs of placental separation
- support collection cord blood or segment collection for blood gasses
- support collection cord blood if Rh negative
- passive or active mngmt of 3rd stage of labour
- support assessment and repair perineal trauma (lacerations and episiotomy)
- closely examine placenta for completeness
207
what do birthers often receive following the delivery of the placenta and why?
- synthetic Oxyotocin (syntocinon) to promote contraction of the uterus
208
what else stimulates the uterus to contract during the 3rd stage of labor (2)
- skin to skin contact
- chest/breastfeeding
209
what occurs after delivery of the placenta?
- the bands of muscle in the uterus acts as a "living ligature" to clamp down on the blood vessels at the site of placental attachment (depending on position of attachment), which are exposed once the placenta detaches from the wall of the uterus
210
when does the 4th stage of labour occur? what period is this for the birther and baby
- first 1-2 hrs after birth
- transition period for birther and baby
211
what is done for the newborn during the 4th stage of labor (3)
- newborn assessment
- VS
- breastfeeding/chestfeeding/newborn feeding
212
what is done for the birther in the 4th stage of labour (8)
- admin of oxytocin or other uterotonic meds to stimulate uterine contractions
- pain mnmgt
- VS
- assess vaginal bleeding and fundus
- hygeine
- elimination (for full bladder, encourage to void)
- support the repair perineal trauma
- assess perineum and repair
- post anesthesia recovery --> removal of epidrual catheter
213
how often are VS done in 4th stage of labour
- q15 min x4
- then every 30 min (BP, pulse, RR)
- temp x1
214
what is an imp consideration w touch and massage for pain
- ask abt pt's preferences
