Labor and Birth 2 maternity exam 2
What is the definition of pre-term? - correct answer - The occurrence of regular uterine
contractions accompanied by cervical dilation and effacement before the end of the 37th week
- One of the biggest contributors to perinatal morbidity and mortality in world
- 1:10 infants in US are born prematurely
Why does gestational age matter/what are preterm babies at risk for? - correct answer - Death
- Respiratory distress issues
- Intraventricular hemorrhage (bleed into brain)
- NEC (issue with bowels)
- Sepsis
- Retinopathy of prematurity (blind related to high O2)
- Hearing loss
- Low birth weight
- Cerebral palsy
- Anemia, thrombocytopenia (low platelets increase risk of bleeding)
- Jaundice
If a cervix is 4/80/-1 what does that mean? - correct answer - Dilated = 4
- Effacement = 80%
- Station = -1
(Dilation/effacement/station)
What is station? - correct answer - 0 = presenting part at ischial spines
- -1 to -3 = above the spines
- +1 to +3 = below spines
What is engagement? - correct answer It is the presenting part (cephalis "head") is at 0 station
What is crowning? - correct answer - Crowing is when the presenting part stays visible at
introitus "entrance to the vagina" between contractions
Julia has been in labor x 10 hrs; cervix is 4/80/-1; contractions q 4-5 mins x 50 secs with
moderate palpation. What stage of labor is she? - correct answer - Stage 1, active
, Labor and Birth 2 maternity exam 2
What determines how fast a baby is born and whether the birth is vaginal or c-section? - correct
answer - The 5 P's determine how fast and if it is her first or second baby.
- Depends on if she had a prior c-section (but risk and benefit)
What are the 5 P's? - correct answer 1. Passenger (fetus)
2. Passageway (birth canal)
3. Powers (contractions)
4. Position (maternal)
5. Psychological response
What is "the passenger"? - correct answer - Size
- Position (lie, presentation, position, attitude)
If a mother has a macrosomia baby what might happen to the mother? - correct answer She
may not be able to have a vaginal delivery do to her pelvis being to narrow
What are the two factors to determine if a baby is macrosomia? - correct answer - 4000-4500
grams (8-13 to 9-15 lbs)
- >90% for gestational age
What is fetal lie? - correct answer - Longitudinal lie (up and down)
- Transverse lie (side ways/horizontal)
What is fetal presentation? - correct answer - What part is seen through vaginal opening first
- Face presentation (bruised face)
- Brow presentation (bruised face)
- Vertex presentation (cephalic; what we want)
- Breech presentation (c-section needed)
- Shoulder presentation (c-section needed)
Face presentation - correct answer The head is fully extended and the face presents
Brow presentation - correct answer The eyebrows or an eyebrow as the first presenting part
Vertex presentation (cephalic) - correct answer Most common. Fetal head fully flexed. Fetal
attitude is general flexion with CHIN on CHEST
Breech presentation - correct answer Birth position in which the buttocks, feet, or knees
emerge first
