Q

What are the labor phases of Stage 1 of labor?

A

Latent Phase
Active Phase
Transition (deceleration phase)

17
Q

What are the labor phases included in Stage 2 of labor?

A

Lull (complete dilation until urge to push)
Active bearing down
Perineal (crowning)

18
Q

What are the signs of the 3rd stage of labor?

A

Gush of blood
Cord appears to lengthen
Uterus becomes globular
Uterus rises anteriorly

19
Q

What is included in active management in the third stage of labor?

A
  • Administration of uterotonic (oxytocin) soon after delivery of anterior shoulder
  • Application of fundal pressure after delivery of placenta
  • Controlled traction on umbilical cord
20
Q

A women with severe risk factors for gestational diabetes should be screened when?

A

As soon as possible

21
Q

When should a women with limited risk factors be screened for gestational diabetes?

A

Between 24 and 28 weeks gestation

22
Q

What is the recommended imaging modality for the first trimester?

A

TVUS

Structures that should be visualized during this exam include the gestational sac, embryo, ovaries, yolk sac, CRL, and fetal heart rate

23
Q

How should progression of labor be tracked?

A

The progress is best evaluated by assessing cervical dilation, descent, and position and should be recorded on a labor graph to detect obvious deviations from a normal course.

24
Q

The most common cause of postpartum hemorrhage is

A

Uterine atony

25
Q

In a complete breech presentation, the fetus’ presents

A

Hips and knees are flexed

26
Q

During oocyte formation in the ovary, there are various stages that the oocyte must go through in order to be ready for ovulation and subsequent fertilization. What is the term used for a mature follicle on the ovary which contains the oocyte that is ready for ovulation?

A

Graffian Follicle

27
Q

Graafian follicles contain several layers of cells which make up the follicle. What is the outer most layer which provides connective tissue support?

A

Theca externa

28
Q

Prolactin causes milk synthesis. Suckling stimulus causes release of prolactin and maintains synthesis and release of prolactin. What parameter does the suckling stimulus inhibit with respect to cyclicity?

A

GnRH

29
Q

Approximately how long does the ova live after being extruded from the ovary?

A

12 to 24 hours
