The relationship between the long axis of the fetus and the mother.
Lie
The fetal part that first enters the maternal pelvis
Presentation
involves the fetus lying longitudinally and the vertex is presenting, however, it is not in an occipitoanterior position
Fetal malposition
During internal rotation in these positions, the fetal head must rotate through an arc of approximately ____ degrees.
135
A head in ______________ position does not fit the cervix like a head in anterior position does.
posterior
Posterior positions usually occur in women with _________________________________________ pelvis.
android, anthropoid, and contracted
Pressure and pain would be experienced by the
woman in her lower back owing to sacral nerve
compression when the fetal head rotates against the
sacrum.
To relieve a portion of the pain, applying
counterpressure on the sacrum by a ___________ may be
done, and __________________ can also help.
back rub ; heat or cold application
Rotations from a posterior position can be aided by having the woman assume a __________________ position, _________________ or ____________________; however, this is tiring for women in labor.
hands-and-knees; squatting; lying on her side
The woman should void _______________ to keep her bladder empty and avoid impeding the descent of the fetus.
every 2 hours
Maternal exhaustion can cause ________________, so a rotation of ____ degrees may not be possible if the contractions are ineffective or if the fetus is larger than average.
uterine dysfunction; 135
Most fetuses are in a breech presentation early in pregnancy; however, by week ___, it turns into a cephalic presentation.
38
Breech presentation increases the fetal risk for
- anoxia
- traumatic injury to the head
- fracture of the spine or arm
- dysfunctional labor
- early rupture of membranes
Fetal heart sounds are heard high in the ______________ in breech presentation.
abdomen
______________________ can determine breech presentation.
Leopold’s maneuver and vaginal examination
Be certain to monitor the ___________________ continuously to detect fetal distress early and provide prompt intervention.
FHR and uterine contractions
In a breech birth, the birth of the __________ is the most dangerous part because a loop of umbilical cord that has passed down alongside the head may be compressed.
head
______________________ is another danger of breech birth because of the pressure changes that has occurred spontaneously.
Intracranial hemorrhage
An infant born from a frank breech position usually extends his or her legs continuously during the first ______________ of life, so be sure to point out to the parents that this is normal.
2 or 3 days
Hips flexed, knees extended (pike position)
Frank breech (50-70%)
Hips flexed, knees flexed (cannonball position
Complete breech (5-10%)
One or both hips extended, foot presenting.
Footling or incomplete (10-30%)
Face and brow presentations are called _________________ or a fetal head presenting at a different angle than expected
asynclitism
Face presentation can be determined through ________________ when the nose, mouth, or chin is felt as the presenting part or through ___________.
