NURS 6700 Exam 3 Content Question with CorrectAnswers
passengers (fetus and placenta)
passageway (birth canal)
powers (contractions)
position of the mother
psychologic response. Correct Answer-What are the five Ps that affect
the process of labor and birth?
Passenger Correct Answer-The way the ?, or fetus, moves through the
birth canal is determined by several interacting factors: the size of the
fetal head, fetal presentation, fetal lie, fetal attitude, and fetal position.
Because the placenta also must pass through the birth canal, it can be
considered a ? along with the fetus; however, the placenta rarely
interferes with the process of labor in a normal vaginal birth.
Presentation Correct Answer-The part of the fetus that enters the pelvic
inlet first and leads through the birth canal during labor at term. Is the
part of the fetus that lies closest to the internal os of the cervix. It is the
part of the fetal body first felt by the examining finger during a vaginal
examination. Factors determining this include fetal lie, fetal attitude, and
extension or flexion of the fetal head.
cephalic presentation-often feel the occiput noted as vertex
Shoulder- feel the scapula
,Breech- you feel the sacrum Correct Answer-Three types of
presentation?
?-head first
?-shoulder first
?-breech
Lie Correct Answer-The relation of the long axis (spine) of the fetus to
the long axis (spine) of the mother. The two primary ? are longitudinal,
or vertical, in which the long axis of the fetus is parallel with the long
axis of the mother; and transverse, horizontal, or oblique, in which the
long axis of the fetus is at a right angle diagonal to the long axis of the
mother
Longitudinal
Transverse
oblique Correct Answer-? lies are either cephalic or breech
presentations, depending on the fetal structure that first enters the
mother's pelvis.
Vaginal birth cannot occur when the fetus stays in a ? lie.
An ? lie, one in which the long axis of the fetus is lying at an angle to the
long axis of the mother, is less common and usually converts to a
longitudinal or transverse lie during labor
,Attitude Correct Answer-Is the relation of the fetal body parts to one
another. The fetus assumes a characteristic posture (attitude) in utero
partly because of the mode of fetal growth and partly because of the way
the fetus conforms to the shape of the uterine cavity. Normally the back
of the fetus is rounded so that the chin is flexed on the chest, the thighs
are flexed on the abdomen, and the legs are flexed at the knees. The
arms are crossed over the thorax, and the umbilical cord lies between the
arms and the legs. This attitude is termed general flexion.
Position Correct Answer-Indicates that portion of the fetus that overlies
the pelvic inlet. Position is the relationship of a reference point on the
presenting part (occiput, sacrum, mentum [chin], or sinciput [deflexed
vertex]) to the four quadrants of the mother's pelvis. Position is denoted
by a three-part abbreviation. The first letter of the abbreviation denotes
the location of the presenting part in the right (R) or left (L) side of the
mother's pelvis. The middle letter stands for the specific presenting part
of the fetus (O for occiput, S for sacrum, M for mentum [chin], and Sc
for scapula [shoulder]). The final letter stands for the location of the
presenting part in relation to the anterior (A), posterior (P), or transverse
(T) portion of the maternal pelvis. For example,
that the occiput is the presenting part and is located in the right anterior
quadrant of the maternal pelvis Correct Answer-ROA means what with
position?
Station Correct Answer-Is the relationship of the presenting fetal part to
an imaginary line drawn between the maternal ischial spines and is a
measure of the degree of descent of the presenting part of the fetus
through the birth canal. The placement of the presenting part is
measured in centimeters above or below the ischial spine
, Engagement Correct Answer-The largest transverse diameter of the
presenting part (usually the biparietal diameter) has passed through the
maternal pelvic brim or inlet into the true pelvis and usually corresponds
to station 0.
passageway, or birth canal Correct Answer-The ? , is composed of the
mother's rigid bony pelvis and the soft tissues of the cervix, the pelvic
floor, the vagina, and the introitus (the external opening to the vagina).
false Correct Answer-The ? pelvis is the part above the brim and plays
no part in childbearing. Lies above this imaginary line; the true pelvis
lies below it (linea terminalis).
true Correct Answer-The ? pelvis is the bony passageway through which
the fetus must travel. It is made up of three planes: the inlet, the mid-
pelvis (cavity), and the outlet.
The pelvic inlet is wider in the transverse aspect (sideways) than it is
from front to back
• The mid-pelvis (cavity) occupies the space between the inlet and
outlet. It is through this snug, curved space that the fetus must travel to
reach the outside. As the fetus passes through this small area, its chest is
compressed, causing lung fluid and mucus to be expelled.•
For the fetus to pass through the pelvis, the outlet must be large enough
