Labor and Delivery (Exam 1) Questuions & Answers
-birth passage (passageway)
-fetus (passenger)
-relationship between the passage and fetus (proportion, fetus size or position)
-physiologic forces of labor (powers)
-psychological factors (psyche) - ANS-what are the critical factors in labor?
fetal presentation - ANS--the manner in which the fetus appears to the examiner during delivery
-head first or butt first?
fetal attitude - ANS--how well flexed or extended the fetus is
-ideally, well flexed
-the relationship of body parts of the fetus
-cephalic
-breech
-shoulder - ANS-what are the three fetal presentations?
cephalic - ANS-the fetus is head first
breech - ANS-the fetus is butt first
breech and shoulder - ANS-what two fetal positions are an indication for c-section?
-vertex or occiput
-sinciput
-brow
-facial - ANS-what are the 4 types of cephalic presentation?
vertex/cephalic presentation - ANS--crown of the head is the presenting part of the fetus
-***most commonly seen presentation and what we want to see
-fetal head is completely flexed and the fetal chin is flexed to the chest
sinciput presentation - ANS--fetal head is partially flexed
-top of head is the presenting part of the fetus
brow presentation - ANS-the eyebrow or forehead is the presenting part of the fetus
facial presentation - ANS--the head is hyperextended
-the face is the presenting part of the fetus
-cephalic/vertex
-well flexed is the most ideal for vaginal delivery - ANS-what is the most ideal type of cephalic
presentation?
right occiput anterior (ROA) - ANS-what is the most common type of fetal presentation?
right occiput anterior (ROA) - ANS--the crown of the fetus's head is to the right and forward of the
mother's pelvis

-face: bones well fused
-base of skull: 2 temporal bones well fused
-vault: **not fused** held together by sutures - ANS-what are the 3 major parts of the fetal head?
sutures - ANS-the membranous spaces between cranial bones
fontanels - ANS--intersections of cranial sutures that can mold
-anterior is diamond shaped
-posterior is triangle shaped
-anterior is open longer than the posterior
-during the delivery process of a vaginal delivery, the sutures can override themselves to make the head
a little smaller through the birthing process
-as the brain grows, these allow for the skull to grow with the brain - ANS-what is the purpose of sutures
and the vault on the fetal head?...
