vaginal and perineal mucosa only, no disruption of muscles

○ Repair only needed for bleeding typically

21
Q

Lacerations:

-2nd degree?

  • 1st degree plus superficial perineal muscles (transverse perineal
    and bulbocavernosus muscles)
22
Q

Lacerations:

-3rd degree?

A

2nd degree plus anal sphincter(s)

23
Q

Lacerations: 4th degree?

A

3rd degree plus anal mucosa

24
Q

How often are episiotomy’s performed?

A

rare! Resist the urge!

● Highlights broad lack of evidence of common practices in obstetrics

25
Q

Cord Complications (list 4 ex’s)

A

Nuchal (“cord around the neck”)
● Cord prolapse (“ride of shame”)
● Marginal cord insertion
● Vasa previa

26
Q

Abnormal fetal heart tracing:

category 1

A

Normal baseline
○ Moderate (5-25) variability
○ +/- accels or early decels
○ No pathologic decels

27
Q

Abnormal fetal heart tracing:

category 2

A

Anything not I or III

28
Q

Abnormal fetal heart tracing:

category 3

A

Bradycardia
○ Absent variability with
Pathologic decels
○ Sinusoidal pattern

29
Q

Bleeding complications: list 3 ex’s

A

“Bloody show”
● Placental abruption
● Placenta or vasa previa
● Postpartum bleeding

30
Q

List an ex of an obstetric EMERGENCY where the maneuver must be committed to memory

A

**Shoulder Dystocia
–Rapid identification and response, and team preparedness key to reducing fetal and maternal
harm

31
Q

Operative Delivery:

  • tools?
  • indications?
A

-Forceps
● Vacuum
● Cesarean

Indications:
○ Maternal exhaustion
○ Expedite delivery for fetal benefit
○ Reduce maternal risks from trial of labor (prior uterine surgery, cardiovascular disease)

32
Q

Labor is divided into which phases?

-active phase is divided into _____

A

**latent and active phases.

The active phase is divided
into 3 stages:
○ first stage involves progressive dilation of the uterine cervix from entry to the active phase
to complete (10 cm) dilation

○Second stage starts at complete dilation and culminates with delivery of the neonate

○ The third stage starts at delivery of the newborn and culminates with delivery of the placenta

33
Q

You are managing a patient in active labor. Her pain is controlled with an epidural
and the fetal heart rate is being continuously monitored with a Category 1 tracing.

Which of the following, if present, would change the fetal heart tracing to Category 2?

  1. A baseline frequency of 165 beats per minute
  2. Early decelerations
  3. A temporary increase in the heart rate lasting 15 seconds, at least 15 beats per
    minute above the baseline
  4. Moderate variability
A
  1. A baseline frequency of 165 beats per minute
34
Q

A 23 year old G1P0 at 39 weeks is admitted in active labor at 5 cm cervical dilation.
In 3 hours her cervix is dilated to 7 cm dilation. After 6 hours, she is dilated to 8 cm.
Which of the following best describes her labor progress?

  1. Her labor is progressing normally
  2. Her labor is protracted
  3. Her labor is arrested
  4. She is in the second stage of labor
A
  1. Her labor is protracted
35
Q

A 26 y/o G4P1021 at 41 0/7 weeks gestation presents for a post-dates induction of
labor. You examine her cervix and note she’s 4 cm dilated, 50% effaced, at -1 station.
Her cervix is soft and anterior. You calculate a Bishop score of 9. What is the
significance of this finding?

  1. She is guaranteed to have a vaginal delivery
  2. Her induction is more likely to fail
  3. Her induction is more likely to be successful using nipple stimulation
  4. Her induction is as likely to result in a vaginal delivery as if she presented in
    spontaneous labor
A
  1. Her induction is as likely to result in a vaginal delivery as if she presented in
    spontaneous labor
36
Q

A patient has arrest in the active phase of labor. You are considering what factors
are contributing to her stalled labor. Which of the following is not one of the three
“Ps”?
1. Passenger
2. Powers
3. Pitocin
4. Pelvis

A
  1. Pitocin
37
Q

Which of the following most accurately indicates that a patient admitted with
contractions is in the first stage of active labor?
1. She is dilated to 5 cm
2. She is having enough pain to request an epidural
3. Her fetal heart rate pattern shows accelerations
4. The slope of cervical change over time is increasing

A
  1. The slope of cervical change over time is increasing
38
Q 
The orientation of the fetal head is assessed based on the location of which feature
of the fetal cranium?
1. The parietal bones
2. The frontal suture
3. The occipital bone
4. The funny bone
A
  1. occipital bone
39
Q 
Which of the following characteristics of a fetal heart rate being monitored in labor
is NOT found in a category I tracing?
1. Late decelerations
2. Early decelerations
3. Accelerations
4. Moderate variability
A
  1. Late decelerations
40
Q

Which of the following is not an indication for making an episiotomy?

  1. Maternal exhaustion
  2. Category 2 or 3 fetal heart rate tracing
  3. Maternal history of cardiovascular disease
  4. To decrease extension of a laceration to a more severe grade
