Q

preterm labor interventions

A
  • start w/ verification of gestational age of fetus
  • goal is to delay delivery for fetal lungs to mature
  • monitor labor contractions
  • assess for changes in effacement and dilation of cervix
  • confirm presence of fetal fibronectin (fFN): protein that helps amniotic sac adhere to uterine wall, detected BEFORE 22 weeks and AFTER 37 weeks
  • detection between 22-37 wks indicates preterm labor

Q

patient teaching to prevent preterm labor

A
  • follow activity restrictions

Q

polyhydramnios

A

abnormally high level of fluid
- complications: preterm labor, amniotic fluid embolism, maternal hemorrhage

17
Q

dysfunctional labor: passage birth control

A
  • pelvic bones are too narrow to allow passage
  • fetus has more tissue to pass through for delivery in obese patient

passenger: the fetus
- size of passenger contributes to dysfunctional labor

18
Q

dysfunctional labor: powers - labor contractions

A
  • contractions are too mild to produce cervical dilation
  • scarring or fibroids disrupt communication between uterine segments, causing uterine muscle to not contract
19
Q

dysfunctional labor: position - fetal presentation

A
  • posterior, brow, shoulder, or breech cause slower cervical dilation and labor progression
20
Q

dysfunctional labor: psyche

A
21
Q

dysfunctional labor: pain management

A
  • IV medication too early can slow
22
Q

dysfunctional labor: patience

A
23
Q

breech presentation

A
24
Q

breech presentation: medical interventions

A
25
Q

macrosomia

A
  • birth weight >4000 grams
  • monitor FHR for nonreassuring patterns
  • preparing woman for cesarean delivery
  • providing emotional support, comfort measures, pain control
26
Q

prolapsed umbilical cord

A
  • obstetrical emergency when cord passes through the cervix at same time as or before presenting part
  • compression causes decreased blood flow and oxygen to fetus: severe, sudden FHR decelerations w/ prolonged bradycardia or variable decelerations on monitor
  • medical interventions
27
Q

precipitous labor and birth

A
  • refers to unusually rapid labor of <3 hours and ending w/ rapid spontaneous delivery of infant
28
Q

nursing care of precipitous labor and birth

A
  • obtaining thorough history
  • assessing pt for impending delivery
  • remaining calm and notifying HCP
  • not leaving pt alone
  • obtaining a precipitous delivery pack
  • washing hands and applying gloves
  • cleansing the perineum
  • giving clear directions to the woman and assistants
  • checking for amniotic sac
29
Q

precipitous labor and birth delivery

A
  • support perineum and infant’s head as it emerges
  • after head emerges, use bulb syringe to suction mouth and nose
  • allow infant to spontaneously complete birth movement
  • check for nuchal cord - umbilical cord aroundf etus’s neck
  • after delivery, thoroughly suction infant’s MOUTH THEN NOSE
  • prevent hypothermia of infant
  • determine 1 and 5 minute Apgar scores
  • assess placenta for intactness (one side meaty, one side shiny)
  • massage the uterus (massage if boggy)
  • place the infant to be breastfed (if mom wishes)
  • documentation
30
Q

shoulder dystocia

A

one or both shoulders wedge in maternal pelvis after the head has been delivered

31
Q

risk factors of shoulder dystocia

A

history of shoulder dystocia

fetal macrosomia

diabetes

excessive maternal weight gain

obesity

post term pregnancy

precipitous second stage of labor
prolonged second stage of labor
induction of labor for potential macrosomia

32
Q

uterine rupture

A
  • nonsurgical opening of uterus
  • notify hcp of suspected rupture
  • notify anesthesiologist, neonatologist, and NICu of impending birth
  • monitor fetal and maternal vital signs
  • give mother oxygen by mask or nasal cannula
  • prepare pt for cesarean birth
  • insert indwelling urinary catheter
  • reassure and provide emotional support
  • perform blood type and crossmatch
  • insert IV line (18g)
33
Q

uterine inversion

A
  • uterine fundus proapses to or through dilated cervix
  • flaccid uterus
  • excessive pressure on fundus during delivery of placenta
  • placenta accreta
  • application of too much traction on umbilical cord in attempt to deliver placenta
34
Q

retained placent

A
  • entire placenta or fragments of placenta still attached to the uterus
35
Q

amniotic fluid embolism (AFE)

A
  • disorder progresses in 2 phases:
    phase 1: hypoxia
    phase 2: massive hemorrhage, uterine atony, and disseminated intravascular coagulation (massive blood loss)
36
Q

AFE signs and symptoms

A
  • dyspnea
  • altered mental status
  • severe hypotension
  • seizures
  • cyanosis
  • fetal bradycardia if undelivered
  • pulmonary edema
  • uterine atony
  • severe hemorrhage
  • cardiac arrest
37
Q

atony

A

not toned uterus

38
Q

AFE medical interventions

A
  • administer oxygen to keep sat normal
  • initiate CPR if pt arrests
  • treat hypotension
  • arrange cesarean birth if required
  • order ABGs, CBC, coagulation tests
  • admit pt to ICU
39
Q

perinatal loss (pregnancy loss)

A
  • ectopic pregnancy
  • spontaneous abortion
  • late pregnancy loss
  • stillbirth
  • newborn death up to 28th day of life
  • fetal demise: death of a fetus at ANY stage
