Exam 1 (Pregnancy, Labor, & Birth) Flashcards
Why do we measure fundal height?
- Estimation of gestational age
- Number of centimeters should equate to weeks gestation
- Ex. 28 cm. = 28 weeks ± 2
How is obstetrical history obtained?
GP:
- Gravidity: Total number of pregnancies
- Parity: Number of pregnancies greater than or equal 20 weeks, irrespective of outcome
Parity can be expanded to give more information: TPAL
- Term: Born at or after 37 weeks
- Preterm: Born 20-36.6 weeks
- Abortions: Spontaneous or elective (before 20 weeks)
- Living: Current number of living children
Kim is currently 32 weeks pregnant and has four living children: North (born at 36 weeks), Saint (born at 38 weeks), Chicago (born at 37 weeks), and Psalm (born at 39 weeks). What is her GPTPAL?
G: 5
P: 4
T: 3
P: 1
A: 0
L: 4
Sam has been pregnant 3 times. They had a miscarriage at 8 weeks, a preterm delivery of a live infant girl at 34 weeks, and a set of twins born at 37 weeks. What is their GPTPAL?
G: 3
P: 2
T: 1
P: 1
A: 1

What is Naegele’s Rule?
- How we estimate due date
- First Day of Last Menstrual Period (LMP) - 3 months + 7 days
What does true labor look like?
- progressive cervical change
- contractions felt in back and abdomen
- contractions increase in duration, intensity, and frequency
- bloody show
- ROM (rupture of membranes)
What does false labor look like?
- no cervical change
- contractions mostly felt in lower abdomen
- contractions have little to no pattern and do not get stronger
- contractions stop with hydration or activity
What is the fetal heart rate baseline?
110-160 beats per minute
What are the different kinds of variability?
- absent: looks like a flat line
- minimal: barely any changes (<5 beats)
- moderate: great! (5-25 beats)
- marked: tells you nothing about the fetus (>25 beats)
What are early decelerations?
and what are they caused by?
- mirror contractions, benign
- often caused by fetal head compression
- no intervention needed
What are variable decelerations?
and what are they caused by?
- sharp, abrupt decrease in heart rate
- often caused by umbilical cord compression
- does not need to be related to contraction
- interventions: position change and amnioinfusion
What are late decelerations?
and what are they caused by?
- start after the contraction has peaked, gradual decrease
- can be caused by poor placental perfusion, hypoxia, maternal hypotension, tachysystole (more than 5 contractions in 10 minutes), infection, etc.
- Interventions: Change position, fluid bolus, oxygen, d/c pitocin, notify provider
What is Magnesium sulfate used for?
- prevent seizures in patients with preeclampsia
- Can temporarily slow or stop preterm labor
- Neuroprotective for preterm baby
