A

Negative affect

32
Q

Which positions can shorten the first stage of labor by 90 minutes?

A

33
Q

What is an episiotomy?

A

An episiotomy is a surgical incision of the posterior aspect of the vulva made during the second stage of labor.

34
Q

In what stage of labor is an episiotomy done?

A

Second stage

35
Q

When is an episiotomy used?

A

An episiotomy is used if the patient is at high risk for a third- or fourth-degree perineal tear or if an expedited delivery is needed because of fetal compromise.

36
Q

What are the risks of an episiotomy?

A

Risks include infection, bleeding, and pain.

37
Q

Prolonged second stage of labor, fetal compromise, or a disorder that limits the mother’s ability to push are indications of what procedure?

A

Operative vaginal delivery, including Forceps-assisted birth, Cesarean deliveries, Vacuum-assisted birth.

38
Q

Forceps-assisted birth, Cesarean deliveries, Vacuum-assisted birth and examples of what?

A

Operative vaginal delivery

39
Q

T/F: After an unsuccessful delivery using forceps, the provider will likely attempt a vacuum-assisted delivery.

A

False.

If one method of operative vaginal delivery is not successful, a second method is contraindicated because it is likely vaginal delivery has not occurred. Attempting a second method of operative vaginal delivery increases risks without improving outcomes.

40
Q

Indications for cesarean delivery include:

A

Failure to progress
Nonreassuring fetal heart rate
Fetal malpresentation
Umbilical cord prolapse
Fetal macrosomia

41
Q

Complications of cesarean delivery for mothers include

A

Bowel and bladder injury during surgery, hemorrhage, amniotic fluid embolism, and infection.

42
Q

A major neonatal complication is

A

respiratory distress

43
Q

Types of cesarian incisions

A

Classical (vertical), low vertical, or low transverse.

44
Q

With what cesarian incision is it best to attempt a vaginal delivery?

A

It is safest to attempt a vaginal delivery after cesarean if a low transverse incision.

45
Q

Cesarian section pre-op care considerations

A

Hemoglobin within last month, type and screen
Antibiotics
Thromboembolic prophylaxis
Fetal heart rate monitoring
Continuous uterine monitoring

46
Q

Cesarian section post-op considerations

A

Routine vitals
Start breastfeeding in delivery room
Remove catheter as soon as possible
Ambulation within 6 hours after anesthesia wears off
Regular diet
Remove dressing in 24 or 48 hours
Increase activity as tolerated
Avoid heavy lifting for 1-2 weeks

47
Q

After reviewing a patient’s prenatal record, the nurse determines which of the following is a contraindication for vaginal birth after cesarean?

A. Nonreassuring fetal heart rate
B. Previous cesarean birth due to a breech presentation
C. Previous cesarean birth with a vertical uterine incision
D. Occiput anterior fetal presentation

A

C. Previous cesarean birth with a vertical uterine incision

A vaginal delivery is contraindicated in women with a vertical uterine incision done in a prior cesarean delivery. Cesarean delivery may be indicated for a nonreasurring fetal heart rate tracing or a breech presentation. An occiput anterior fetal presentation is desirable for a vaginal delivery.

48
Q

What can occur in women attempting a trial of labor after cesarean (TOLAC)?

A

Uterine rupture

49
Q

Symptoms that include the sudden development of a category II or category III fetal heart rate pattern, weakening contraction, and abdominal pain are possible indication of what condition?

A

Uterine rupture

50
Q

tear in the uterine lining secondary to increased pressureWhat are the treatment options for uterine rupture?

A

Treatment includes cesarean delivery and possible hysterectomy.

51
Q

What is uterine rupture?

A

Tear in the uterine lining secondary to increased pressure
Complete
Incomplete
Dehiscence (window)

52
Q

What is cord prolapse?

A

Condition where umbilical cord precedes fetal head in the birth canal.

53
Q

What are causes of cord prolapse?

A

High station
Small or preterm fetus
Malposition of the fetus
Polyhydraminios

54
Q

Treatment for cord prolapse

A

Relieve pressure of the cord to improve blood flow to the fetus and therefore increase oxygenation

55
Q

First sign of a cord prolapse

A

The first sign of a cord prolapse is often a change in fetal heart rate tracing, typically severe fetal bradycardia and variable decelerations.

56
Q

T/F: A cord prolapse is a non acute condition

A

False. A cord prolapse is an obstetric emergency typically requiring immediate cesarean delivery

57
Q

WThe cord should be handled as little as possible to prevent spasm of what?

A

The cord should be handled as little as possible to prevent spasm of the umbilical artery

58
Q

An amniotic fluid embolism, referred to as anaphylactoid syndrome of pregnancy may occur at what points in gestation or labor?

A

May occur in pregnancy, labor, delivery, and the immediate postpartum period.

59
Q

An amniotic fluid embolism is caused when what?

A

Amniotic fluid enters maternal circulation and is associated with a maternal mortality rate of 32%.

60
Q

The cesarian rate is the same as mortality rate from amniotic fluid embolism at what rate?

A

32%

61
Q

What are the initial symptoms of amniotic fluid embolism?

A

Initial symptoms include respiratory failure and cardiac arrest.

62
Q

If the patient survives an amniotic fluid embolism, she is at risk for what?

A

hemorrhagic shock with disseminated intravascular coagulation.

63
Q

When a patient is experiencing an amniotic fluid embolism, what positio is best?

A

Side-Lying

64
Q

A patient delivered 1 hour ago and suddenly experiences cardiac arrest. What should the nurse do next?

A. Call for help.
B. Open airway and assess breathing.
C. Initiate CPR.
D. All of the above.

A

D. All of the above.

An amniotic fluid embolism can occur up to 48 hours after delivery. First interventions include getting help, evaluating breathing, and initiating CPR without delay.

65
Q

Risk for stillbirth is higher in what cases?

A

Risk is higher for adolescents, women over 35 years old, women of African descent, multifetal gestations, congenital anomalies, and maternal disease.

66
