L&D Flashcards
engagement
fetal presenting part widest diameter reaches level of the ischial spines of mother’s pelvis
Extension
fetal head passess beneath the mother’s symphysis pubis
internal rotation
allows the largest fetal head diameters to match largest maternal pelvic daimeters
external rotation
- allows shoulders to rotate internally to fit mom’s pelvis
maternal factor that can inhibit fetal descent
a full bladder
normal FHR
110-160 bpm
fetal tachycardia
> 160/min for 1 min
fetal bradycardia
< 110/min for min or longer
4 Ps
Powers, passageway, passenger, psyche
Tachysystole
Contractions too frequent ( every 2 Mom), too long (>90-120 sec), minimal rest < 30 sec
Pain med that does not affect fetus
Nitrous oxide
Nuchal
Umbilical cord interrupted because of being wrapped around the neck
Reassuring FHR
- average FHR 110-160
- regular rhythm
- accelerations from baseline rate
- no decrease in rate from baseline
Non reassuring FHR
- HR outside normal limits unexplained tachy or brady
- irregular rhythm
- gradual abrupt decrease in rate
Bishops score
- cervical dilation
- length of cervix
- stationing if presenting part
- consistency
- position
