NARM. Obstetric Anatomy- fetopelvic
relationship
Fetopelvic - answer relationship of the fetus to the uterus and pelvis
fetal lie - answer the relation of the long axis (spine) of the fetus to the long axis (spine)
of the mother
transverse
longitudinal
transverse fetal lie - answer indicates that fetus is lying sideways across the pelvis
oblique is sideways at an angle
longitudinal fetal lie - answer normal lie
fetal spine is parallel to maternal spine
cephalic
breech
cephalic presentation - answerbirth position in which any part of the head emerges first
head,face,brow
breech presentation - answerbirth position in which the buttocks, feet, or knees emerge
first
fetal presentation - answerthe foremost part of the fetus that enters the pelvic inlet
shoulder presentation - answerlong axis of baby's body is across the long axis of the
mother's body; shoulder is presented at the cervical opening
compound presentation - answertwo fetal parts present together
Fetal attitude or posture - answerthe relationship of fetal parts to one another. Noted by
the flexion or extension of the fetal joints.
well flexed cephalic attitude will present as a continuous curve of back and head from
fundus to pubic bone.
deflexion of head can be corrected at 35 weeks geststion
flexion and extension - answertwo basic fetal attitudes
flexion- chin touches chest, arms and legs folded in front of body
extension-the head is tilted back with the occiput towards the back
Fetal Denominator - answerthe point on the fetus which is used to determine position
, chin
sacrum
occiput
dorsum
fetal postion - answerrelationship of the presenting fetal part to the front back and sides
of pelvis
LOA - answerleft occiput anterior; back of baby's head is anterior to the pelvis and tilted
to the left side
LOP - answerLeft occiput posterior ("back labor")
LOT - answerleft occiput transverse
ROA - answerRight Occiput Anterior (most common)
ROT - answerright occiput transverse
ROP - answerright occiput posterior
occiput anterior (OA) - answerback of the skull toward the chest (most favorable and
common position)
Occiput posterior (OP) - answerback of the skull toward the back
-more painful than OA
station - answerthe relationship of the presenting part to an imaginary drawn line
between the ischial spines
0 station is parallel to... - answerischial spines
above ischial spine - answerminus station
Below the ischial spines - answerThe fetus of a woman in labor is at +1 station. At what
place in the pelvic area does the nurse conclude that the presenting part is located?
Engagement - answeroccurs when the widest part of the presenting part passes
through the pelvic inlet also called lightening
floating - answerpresenting part is entirely out of the pelvis
dipping - answerthe presenting part has passed through the presenting part but is not
engaged
fully engaged - answerthe presenting part is at or below the ischial spines
