32
Q

What are the general interventions for all the stages of labor?

A
  • maternal and fetal vital signs
  • IV fluids
  • contraction monitoring
  • basic comfort and pain control
33
Q

Why would local anesthesia be used during labor?

A

Local anesthesia would be used in the perineal area if the laboring client has to get an episiotomy.

34
Q

What is an episiotomy?

A

An episiotomy is a surgical cut of the perineum to quickly enlarge the opening for the baby to pass through.

35
Q

What are the interventions after an episiotomy?

A
  1. decrease swelling and discomfort
    • ​apply ice packs​
    • sitz baths
    • analgesic spray or ointment
  2. prevent constipation
  3. take showers instead of baths
    • baths increase the risk of infection
36
Q

What is a lumbar epidural block?

A

When a catheter is placed in the lumbar region to deliver pain meds continuously during labor.

37
Q

Interventions:

Lumbar epidural block

A
  • monitor for hypotension
  • increase IVF for hypotension
  • monitor for bladder distention

The nerve that controls blood pressure and bladder control may get blocked.

38
Q

What is a subarachnoid spinal block?

A

Pain medication is administered once in the spine with a needle right before birth.

39
Q

Interventions:

Subarachnoid spinal block

A
  1. lie flat 8 - 12 hours after injection
    • to prevent leakage of fluid and headache
  2. monitor for hypotension
    • increase IVF for hypotension

The nerve that controls blood pressure may get blocked.

40
Q

What opioid pain medicines can be given to a laboring woman?

A
  • hydromorphone
  • meperidine
  • fentanyl
41
Q

Side effects and nursing considerations:

Opioid pain meds during labor

A
  • assess for decreased respirations and hypotension
  • don’t give to client with history of opioid dependence
  • antidote is naloxone
42
Q

What is induction?

A

Induction is medications that are given to quicken the laboring process.

43
Q

What classifications of meds would be given for induction?

A
  • Prostaglandins - misoprostol
  • Uterine stimulants - oxytocin
44
Q

What is an amniotomy?

A

An amniotomy is when the amniotic membranes are ruptured using a hook to quicken the labor process.

45
Q

What are the assessments after an amniotomy?

A
  1. assess for prolapsed cord
  2. assess for meconium-stained fluid
  3. assess for bloody fluid
    • may indicate abruptio placenta or fetal trauma
  4. assess for bad odor
    • may indicate infection
46
Q

What is external rotation?

A

External rotation is manipulating the fetal position by pressing on the mom’s abdomen.

It is done to get the baby in a more favorable position for labor.

47
Q

What is a cesarean delivery?

A

Cesarean delivery is an abdominal incision is made through the uterus to deliver the baby.

48
Q

What are the interventions before a Cesarean delivery?

A
  • informed consent is signed
  • maternal and fetal vital sign monitoring
  • start IV fluids
  • insert foley
49
Q

What are the interventions after a Cesarean delivery?

A
  • assess for bleeding and infection
  • encourage ambulation to prevent DVT
  • encourage turning, coughing and deep breathing to prevent pneumonia
  • pain control
  • promote bonding
50
Q

What is PROM?

A

PROM is premature rupture of the membranes before 37 weeks’ gestation.

Client will report continuous vaginal wetness. Have her report to hospital as soon as possible for delivery.

51
Q

Interventions:

PROM

A
  • check nitrazine test to see if it’s positive for amniotic fluid
  • no vaginal exams - increases the risk of infection
52
Q

Immediate complication

What is a prolapsed umbilical cord?

A

A prolapsed umbilical cord is when the umbilical cord drops through the open cervix into the vagina ahead of the baby.

The cord can then become trapped against the baby’s body during delivery.

53
Q

Interventions:

Prolapsed umbilical cord

A
  • elevate any parts that are lying on the cord with a gloved hand
  • put mom in extreme Trendelenburg position
  • give oxygen 8 - 10 L/minute by mask
  • prepare for immediate birth
54
Q

What is placenta previa?

A

Placenta previa is when the placenta has grown over the cervix.

55
Q

What are the characteristic signs of placenta previa?

A

painless, bright red bleeding

56
Q

Interventions:

Placenta previa

A
  • maternal vital signs and fetal monitoring if there is excessive bleeding
  • no vaginal exams
  • bed rest
57
Q

Immediate complication

What is abruptio placenta?

A

Abruptio placenta is when the placenta has separated off the uterine wall.

58
Q

What are the characteristic signs and symptoms of abruptio placenta?

A
  • severe pain and dark red blood
  • rigid and tender uterus that doesn’t fully relax between contractions
59
Q

Interventions:

Abruptio placenta

A
  • cesarean delivery if baby is not coming out immediately
  • blood transfusion to mom
60
Q

Describe:

Vena cava syndrome

A

Vena cava syndrome is is another word for supine hypotension syndrome.

It is not a medical emergency, but interventions are required. It is when the mom is laying on the vena cava and cutting off circulation to the baby.

61
Q

What are the characteristic signs and symptoms of vena cava syndrome?

A
  • hypotension
  • lightheadedness
62
Q

Interventions:

Vena cava syndrome

A
  • put mom on left side
  • or put mom with a pillow under one side of the hips

This position gets pressure off the vena cava.

63
Q

What is the gestational age of preterm labor?

A

Between 20 - 37 weeks of gestation

64
Q

Medications:

Preterm labor

A
  1. give tocolytics to prevent labor
    • magnesium sulfate
  2. give steroids to increase production of surfactant to fetal lungs
    • betamethasone or dexamethasone
65
Q

Describe:

Dystocia

A

Dystocia is a difficult labor that is prolonged or painful.

It is caused by a large fetus, position of fetus or the mom’s pelvis shape.

66
Q

Describe:

Amniotic fluid embolism

Immediate complication

A

Amniotic fluid embolism is when an embolism can lead to respiratory failure and bleeding.

67
Q

Interventions:

Amniotic fluid embolism

A
  • give oxygen, possible intubation, and ventilator
  • cesarean delivery once the mom is stabilized
68
Q

Signs and symptoms:

Fetal distress

Immediate complication

A
  • fetal heart rate is < 110 or > 160 beats/minute
  • meconium-stained amniotic fluids
  • fetal hypo or hyperactivity
  • severe variable or late decelerations
69
Q

Describe:

Intrauterine fetal demise

A

Intrauterine fetal demise is when the baby dies in utero.

70
Q

Interventions:

Intrauterine fetal demise

A
  • assess mom for DIC (bleeding and clotting disorder)
  • emotional support
71
Q

What is “VEAL CHOP”?

A

VEAL CHOP is an acronym to remember fetal heart rate pattern changes.

The order of the letters in VEAL correlates to accelerations or decelerations and the letters in CHOP help you remember the cause of each fetal heart rate change.

72
Q

What do the letters “VEAL CHOP” stand for?

A
  1. Variable decelerations in baseline fetal heart rate
    • Cord is compressed
  2. Early decelerations of fetal heart rate
    • Head is compressed​
  3. Accelerations of fetal heart rate
    • O: everything is OK​
  4. Late decelerations:
    • Placenta is compressed
73
Q

What type of fetal heart rate decelerations are these?

A

Variable decelerations caused by cord compression.

There is an abrupt decrease in fetal heart rate. They have a U, V or W shape. Can occur at any time during contraction cycle. Can be an emergency if fetal heart rate declines to less than 70 beats/minute.

74
Q

What type of fetal heart rate decelerations are these?

A

Early decelerations caused by head compression.

There is a gradual decrease in fetal heart rate and a return to baseline associated with contraction. This is a normal finding.

75
Q

Immediate complication

What type of fetal heart rate decelerations are these?

A

Late decelerations caused by placenta compression.

There is a gradual decrease in fetal heart rate. The lowest heart rate occurs after the contraction peak.

76
Q

Immediate complication

What are the general interventions if the mom or baby is having life-threatening distress during labor?

A
  • put mom in Trendelenburg position
  • give oxygen 8-10 liters by mask
  • give IV fluids
  • blood transfusion if needed
  • prepare for cesarean delivery
77
Q

What is a fetal scalp electrode?

A

A fetal scalp electrode is a spiral wire placed directly on the fetal scalp or presenting part used to measure and record a very accurate fetal heart rate.

They are placed when there is a non-reassuring fetal heart rate.
