Labor and Delivery Flashcards
regularly occurring, uncomfortable-to-painful uterine contractions result in progressive effacement and dilatation of the cervix
labor
stimulate uterine contractions and which may soften the cervix independent of uterine activity
prostaglandins
amplify the biologic effect from a given amount of oxytocin
increased myometrial oxytocin
When should a woman who is in labor come into the hospital?
Contractions every 5 minutes for 1 hour, gush of fluid, decreased fetal mov’t
Stage of delivery with cervical effacement and early dilatation
latent phase
Stage of delivery when cervix is dilated 3-4cm
active phase
What stage of delivery does delivery of placenta correlate with?
stage 3
What stage of delivery is the hour immediately after delivery?
stage 4
What is the length of the complete dilation of the cervix for a full-term infant?
10cm
contractions occur every 5 to 10 minutes last for 30-45 seconds. About 20-30mmHg in intensity
early labor
What is the only way to measure intensity of contractions accurately?
internal uterine monitor
Warning signs of fetal heart rate
late decelerations, bradycardia, decreased variability
Associated with umbilical cord compression
variable decelerations when mother has a contraction
Mother has contraction, then heart decelerates indicates what?
decreased oxygen to fetus
The most urgent pattern on fetal monitoring
sinusoidal
Begins with complete dilatation of the cervix and ends with delivery of the baby
2nd stage of delivery
Direction baby’s head must go when descending through the pelvis
inferoposterior direction and then in an inferoanterior direction
What are the 5 cardinal movements of labor?
engagement, descent, flexion, internal rotation, extension
Biparietal diameter, the widest transverse diameter of the fetal head, has passed the plane of the pelvic inlet
engagement
As forces cause descent of the fetus through the pelvis, soft tissue and bony resistance is encountered
flexion
The head goes through the pelvis (depending on type) sideways
internal rotation
After further descent, the fetal head is delivered
extension
At what point can you gently put traction on the cord?
Once the placenta separates
Most common major operation performed in the U.S
C-section
Bottom first position of fetus! Generally known ahead of time automatic c-section
breech
Three meds newborn gets
Hep B vaccine, arthyromycin in eyes, vitamin K
