N351 EXAM 2 DRUGS / 100+ COMPLETE QUESTIONS
AND CORRECT DETAILED ANSWERS
What are the four main components of the birth process? - (answer)1) powers
2) passage
3) passenger
4) psyche
What are the three characteristics of uterine contractions? - (answer)1)
Coordinated:
frequency (beginning of one to beginning of next)
duration (beginning to end of same contraction)
intensity (strength of a contraction)
2) involuntary (can't control when they come)
3) intermittent (they come an dgo)
What are the phases of the contraction cycle? - (answer)1) increment (increasing
strength)
2) acme/peak (most intense moment)
3) decrement (decreasing intensity as uterus relaxes)
,How is blood flow to the placenta affected during a contraction? - (answer)blood
flow to placenta decreases as muscle fibers of the uterus constrict around
maternal spiral arteries that supply the placenta
When are maternal vital signs best assessed? - (answer)during the interval
between contractions
What is "bearing down"? - (answer)uterine contractions -> primary force that
moves fetus through maternal pelvis
maternal pushing efforts: woman feels urge to push as fetus distends the vagina
and puts pressure on the rectum
What aspects are involved in "passage" phase of birth? - (answer)maternal pelvis
and soft tissues
pelvis is more important to outcome of labor than the soft tissue
soft tissue (cervix) will efface and dilate
What is "complete" dilation?
"complete" effacement? - (answer)10 cm = complete
fingertip= 1 cm
,100%= thinning and shortening of cervical thickness
What does the passenger include? - (answer)the fetus, membranes, and placenta
(all need to come out)
What is "fetal presentation"? - (answer)the fetal part that first enters the pelvis
cephalic/head can either be 1) vertex/occiput (head is flexed) or 2) face (head
extended)
shoulder presentation
breech (frank, full/complete, or footling)
Different breech positions - (answer)frank= folded
full/complete= squatting position
footling= one or both feet coming first
How do we want the baby to present? - (answer)cephalic/head presentation (feel
for fontanels)
smallest diameter= occiput
, What is the "fetal attitude"? - (answer)relationship of fetal body parts to each
other (NOTHING to do with the mom)
flexion=normal (humble, prayerful position)
extension ("nose in the air"= haughty)
What is the "fetal lie"? - (answer)orientation of the long axis (spine) of the fetus
to the long axis of the woman
longitudinal lie= vertical (what we want)
transverse lie= horizontal (not good)
What is "fetal position"? - (answer)location of fixed reference point on the
presenting part in relation to the four quadrants of the maternal pelvis
3 parts:
1) orientation to side of maternal pelvis (L for left, R for right)
2) Fetal presenting part (O for occiput, M for mentum/chin, S for sacrum)
3) Orientation of presenting part to the mom (A for anterior/front, P for
posterior/back, T for transvers)
