Leopolds Maneuvers** - Answer Abdominal palpation conduction for determination of
fetal weight, lie, presentation, position and engagement should be performed prior to
placement of EFM.
If the fundal height does not appear appropriate for gestational age after use of the
Leopolds, what do you do? ** - Answer Measure from the suprapubic prominence to the
top of the fundus in centimeters.
If the uterus is shaped longitude and ovoid what does this suggest?** - Answer This
suggests a longitudinal lie.
If the uterus is shaped transverse ovoid what does this indicate?** - Answer This
indicates transverse lie
Is there a long smooth prominence to one side of the abdomen? ** - Answer This

Turn to face woman's feet; Place hands on sides of uterus with fingers pointed toward
the pelvic outlet.
On one side, slide fingers downward and feel for cephalic prominence.
If head is flexed.
Fetal Lie - Relationship of the long axis (spine) of the fetus to the long axis (spine) of the
mother
Types: Longitudinal (vertical) primary lie found in labor (cephalic or breech)
Transverse Lie: fetal spine is perpendicular to the maternal spine
Oblique lie: fetal axis at right angle diagonal to maternal axis
