Q

Premonitory signs of labor

A

-Cervical changes (softening or dilation 1 hr - 1 m before labor)
-Lightening (baby drops into pelvis, uterus lowers, breathing is easier, decrease in gastric reflux, increased pelvic pressure, cramping, and edema; occurs 2 weeks or more before labor in primis and at time labor in multis)
-Increased energy level (nesting, spending more time on household chores and w/ children at home; 24-48 hrs before labor, increase in EPI)
-Bloody show (mucus plug expels as result of cervical softening; mixes w/ blood to produce pink-tinged secretions)
-Braxton hicks contractions (stronger and more frequent, pulling sensation at top of uterus; last abt 30 sec - 2 min; if it occurs more than 4-6x/hr –> call doctor)
-Spontaneous rupture of membranes (loss of amniotic fluid aka PROM, labor begins within 24 hrs, infection is possible, danger of cord prolapse)

Q

Cardinal movements during labor

A

-Engagement: greatest transverse diameter of head in vertex (biparietal diameter) passes thru pelvis inlet (0 station)
-Descent: downward movement of head into pelvic inlet (pressure of amniotic fluid and fundus d/t fetus’s buttocks or head), contractions of abdominal muscles, extension of fetal body)
-Flexion: vertex meets resistance from cervix, walls of pelvis, or pelvic floor; chin is brought into contact w/ fetal thorax and presenting diameter is changed from occipitofrontal to suboccipitobregmatic
-Internal rotation: as head descends, lower portion of head meets resistance from one side of pelvic floor, head rotates 45 degrees)
-Extension: nucha (base of occiput) becomes impinged under symphysis, occurs after internal rotation is complete, anterior fontanelle, brow, nose, mouth, chin are born
-External rotation: after head is born, it untwists, causing occiput to move 45 degrees to its original L or R position (restitution); allows shoulders to rotate internally to fit thru pelvis
-Expulsion: rest of body occurs more smoothly after birth of head and shoulders

3: what is the presenting part
4: is the fetal head flexed and engaged in the pelvis

45
Q

Fetal assessment during labor and birth

A

-Amniotic fluid analysis
-FHR monitoring: handheld vs electronic; intermittent vs continuous; external vs internal

46
Q

Analysis of amniotic fluid

A

-Clear when ruptured
-Spontaneous or artificial by means of amniotomy (amnihook)
-Cloudy or foul-smelling amniotic fluid indicates infection
-Green fluid indicates fetus has passed meconium secondary to transient hypoxia, prolonged pregnancy, cord compression, IUGR, maternal HTN, DM, chorioamnionitis (normal if fetus is breeched)
-Prevent meconium aspiration syndrome, which can lead to respiratory distress
-Necessitates suctioning after head is born and infant takes a breath, trach suctioning if apgar score is low
-Amnioinfusion (sterile water or LR’s)

47
Q

Analysis of FHR

A

-Determines fetal oxygen status
-Intermittently using fetoscope or a doppler or continuously w/ EFHR

48
Q

Guidelines for assessing FHR

A

-Initial 10-20 min continuous FHR assessment on entry into labor/birth area
-Completion of prenatal and labor risk assessment on all clients
-Intermittent auscultation q30 min during active labor for low-risk women and q15 min for high-risk women
-During 2nd stage of labor intermittent auscultation q15 min for low-risk women and q5 min for high-risk women

49
Q

Intermittent FHR monitoring

A

-Auscultation using doppler or fetoscope
-For low-risk women
-Low in cost and used routinely
-Does not document fetal distress during labor
-Start listening to FHR at end of contraction so that late decelerations could be detected
-Pressure of device is uncomfortable
-Auscultation for full min after contraction; from then on, unless there is a problem, listen for 30 sec and multiply value by 2
-Heard best at fetal back or at lower quadrant of maternal abdomen

50
Q

Continuous electronic FHR monitoring

A

-Uses machine (EFM) to produce continuous tracing of FHR
-Recommended for high-risk babies
-For women w/ oxytocin finusing, epidural analgesia, HTN, presence of meconium
-Produce graphic record of FHR pattern
-Primary objective: provide info abt fetal oxygenation and prevent fetal injury from impaired oxygenation, to detect FHR changes early before they are prolonged and profound

51
Q

Continuous external monitoring

A

-Attached to belt around woman’s abdomen
-2 ultrasound transducers
-Used when membranes intact and cervix is not yet dilated
-Measures uterine contractions
-Artifact: describes irregular variation or absence of FHR that results from mechanical limitation of monitor or electrical interferance

52
Q

Continuous internal monitoring

A

-For women or fetuses at high-risk
-Multiple gestation, decreased fetal mvmt, abnormal FHR on auscultation, IUGR, maternal fever, preeclampsia, dysfunctional labor, preterm birth, DM, HTN
-Spiral electrodes into fetal presenting part (usually head)
-Most accurate method
-Unlike external monitoring, it detects both short-term changes and variability and FHR dysrhythmias
-Also, maternal position changes don’t interfere w/ quality of tracing

53
Q

Criteria for using continuous internal monitoring of FHR

A

-Ruptured membranes
-Cervical dilation of at least 2 cm

80
Q

Benzodiazepines

A

-Minor sedative effects
-Diazepam IV to stop seizures from eclampsia, causes CNS depression
-Calm woman out of control
-Lorazepam for tranquilizing effect but increases sedation
-Midazolam IV produces good amnesia but no analgesia (adjunct for anesthesia), causes CNS depression

81
Q

Systemic analgesia

A

82
Q

Regional analgesia

A

-Epidural block: continuous infusion or intermittent injection; usually started when dilation > 5 cm

-Combined spinal-epidural block (“walking epidural”)
-Patient-controlled epidural
-Local infiltration (usually for episiotomy or laceration repair)
-Pudendal block (usually for 2nd stage, episiotomy, or operative vaginal birth)
-Intrathecal (spinal) analgesia: during labor and C-section

83
Q

General anesthesia

A

-Emergency C-section birth or woman w/ contraindication to use of regional anesthesia
-IV injection, inhalation, or borth
-Commonly, 1st thiopental, propofol IV to produce unconsciousness
-Next, muscle relaxant
-Then, intubation, followed by administration of nitrous oxide and O2; volatile halogenated agent also possible to produce amnesia
-Fetal depression
-Administer nonparticulate (clear) oral antacid (bicitra or sodium citrate) or PPI (protonix) to reduce gastric acidity
-Wedge under R hip to displace gravid uterus and prevent vena cava compression in supine position

84

85
Q

Nursing care during 1st stage of labor

86
Q

1st stage of labor: admission assessment

A

-Maternal health hx: physical exam, fundal height, uterine activity, status of membranes, cervical dilatation, FHR, pain level
-Fetal assessment
-Lab studies: routine (urinalysis, CBC), syphilis screening, HbsAg screening, GBS, HIV (w/ woman’s consent), drug screening
-Psychological status assessment

87
Q

1st stage of labor: continuing assessment

A

-Woman’s knowledge, experience, expectations
-VS
-Uterine contractions
-Pain level
-Coping ability
-FHR
-Episiotomy has been restricted d/t risk of procedure and unclear benefits of use
-Increase in apprehension or irritability
-Spontaneous rupture of membranes
-Sudden appearance of sweat on upper lip
-Increase in blood-tinged show
-Low grunting sounds
-Complaints of rectal and perineal pressure
-Beginning of involuntary bearing-down efforts

88
Q

Nursing management: 2nd stage assessment

A

-Typical signs of 2nd stage
-Contraction frequency, duration, intensity
-Maternal VS q5-15 min
-Fetal response to labor via FHR q 5-15 min
-Amniotic fluid w/ rupture of membranes
-Vaginal discharge
-Coping status of woman and partner

89
Q

Nursing management: 2nd stage interventions

A

-Supporting woman and partner in active decision making
-Supporting involuntary bearing-down efforts; encouraging no pushing until strong desire or until descent and rotation of fetal head well advanced
-Providing instructions, assistance, pain relief
-Using maternal positions to enhance descent and reduce pain
-Preparing for assisting w/ delivery

90
Q

Nursing management: 2nd stage birthing interventions

A

-Cleansing of perineal area and vulva
-Assisting w/ birth, suctioning of newborn, and umbilical cord clamping
-Providing immediate care of newborn: drying, apgar score, identification

91
Q

2nd stage of labor: birthing techniques

A

-Pushing only when feels an urge to do so
-Delaying pushing up for up to 90 min after complete dilation
-Using abdominal muscles when bearing down
-Short pushes of 6-7 sec
-Focusing attention of perineal area to visualize newborn
-Relaxing and conserving energy between contractions
-Pushing w/ open glottis and slight exhalation

92
Q

2nd stage of labor: immediate care of newborn

A

-Dry and provide warmth
-Some places immediately place baby on mother’s abdomen
-APGAR score at 1 and 5 min
-Appearance (skin color), pulse (HR), grimace (reflex irritability), activity (muscle tone), respiration (breathing)
-7 or up is good

93
Q

Nursing management: 3rd stage of labor assessment

A

-Placental separation (3rd stage is complete when placenta is delivered): firmly contracting uterus, changing in uterine shape from discoid to globular, sudden gush of dark blood, lengthening of umbilical cord
-High levels of oxytocin and endorphins and adrenaline
-Protect natural hormonal process by ensuring unhurried and uninterrupted contact between mother and newborn after birth
-Placenta and fetal membranes exam
-Perineal trauma: firm fundus w/ bright red blood trickling –> laceration, boggy fundus w/ red blood flowing –> uterine atony, boggy fundus w/ dark blood and clots –> retained placenta
-Episiotomy
-Lacerations

94
Q

Nursing management: 3rd stage of labor interventions

A

-Instructing to push when separation apparent
-Giving oxytocin if ordered
-Assisting woman to comfortable position
-Providing warmth
-Applying ice to perineum if episiotomy
-Explaining assessments to come
-Monitoring mother’s physical status
-Recording birthing statistics
-Documenting birth in birth book

95
Q

Nursing management: 4th stage assessment

A

-VS stable (q15m during 1st hour then q30m for next hour if needed): pulse 60-70 BPM, fever indicates dehydration (<100.4) or infection (>101) during labor, RR 16-24/min, BP returns to prepregnancy level
-Fundus needs to remain firm to prevent excessive hemorrhage (feels like grapefruit, located in midline and below umbilicus), gently massage if boggy
-If fundus is displaced to R of midline, suspect full bladder as cause; could cause uterine hemorrhage secondary to bogginess
-Perineal area
-Comfort level (pain < 3)
-Lochia
-Bladder status (diuresis should occur)

96
Q

Nursing management: 4th stage interventions

A

-Support and information

-Bladder status and voiding
-Comfort measures
-Parent-newborn attachment
-Monitor ability to void
-Teach mother how to assess her own fundus
-Safety technique education to prevent newborn abduction
-Apply ice pack to perineum to reduce
-Observe for early parent-infant attachment
