A

ED FIRE ERE

Engagement
Descent
Flexion
Internal Rotation
Extension
External Rotation

What are the 3 signs of placental separation?

A
  1. Cord lengthening
  2. Gush of blood
  3. Uterine fundal rebound
22
Q

What constitutes the second-degree perineal laceration?

A

Laceration extends into the perineal body and spares the anal canal sphincter

23
Q

Most dreaded complication in an uncorrected transverse lie?

A

Uterine rupture

24
Q

Factor that may cause prolonged occiput transverse presentation?

A

Epidural analgesia

25
Q

Which is the most common site of laceration after labor and delivery ?

A

Perineum

26
Q

Degree of laceration involving internal anal sphincter but not the rectal mucosa?

A

Third degree laceration ( IIIC )

27
Q

What antibiotic will you give as a single dose at the time of repair of a fourth degree laceration?

A

2 nd gen Cephalosporins or Clindamycin for penicillin allergic women

28
Q

Shortest AP diameter of the pelvic inlet ?

29
Q

Pelvis type that has <12 cm transverse diameter inlet ?

A

Anthropoid

30
Q

Presentation if a fetal extremity presents along side the vertex or breech?

A

Compound extremity / presentation

31
Q

Percentage of term pregnancies complicated by PROM that will go into spontaneous labor in the absence of obstetric intervention?

A
  1. 50% within 12 hrs +20
  2. 70% within 24hrs +15
  3. 85% within 48 hrs +10
  4. 95% within 72 hrs
32
Q

What is the proposed pathophysiology of PROM?

A

Pathogenic bacteria causes premature release of collagenase

33
Q

A 25 yo G1P0 consulted for premature contractions which persist even after resting. However, she never had any previous prenatal check ups with you. On physical exam, her fundic height with fetal heart tone of 145bpm at the left quadrant. LMP based aog is 27-28wks . What is the best tool to rule out growth retardation?

A

What is the relation of the fetal head to the ischial spines of the female pelvis?

A

Engagement

36
Q

What is the purpose of flexion in labor?

A

Allows the smallest diameter of the fetal head to pass the ischial spines.
