Acme
The peak of the contraction
Decrement
The descent or relaxation of the uterine muscle
Duration
The time from the beginning to the end of one contraction
Frequency
The time from the beginning of one to the beginning of the next contraction
,Increment
The building up of the contraction
Intensity
The strength of the contraction
Effacement
The process of shortening and thinning of the cervix (usually presented as a percentage related to the
length of the cervical canal, as compared with a non-effaced cervix)
Dilation
opening and enlargement of the cervix that progressively occurs throughout the first stage of labor
What is the purpose of the vaginal exam?
assessment of cervical dilation, effacement and station, fetal position and presentation, rupture of the
membranes, prolapse of the umbilical cord, and to perform fetal scalp stimulation
What is fetal lie?
The relationship of the spine of the mother to the spine of the fetus. It can be longitudinal, transverse
(perpendicular), or oblique.
Longitudinal lie
,The fetal long axis is parallel to the mother's long axis. The fetus is either in a breech or vertex
presentation
Transverse lie
The long axis of the fetus is at a right angle to the mother's long axis. This is incompatible with a vaginal
delivery if the fetus remains in this position
Oblique lie
Is one that is at some angle between the longitudinal and the transverse lie.
What is fetal attitude
The relationship of the fetal body parts to one another: Flexion (vertex), Extension
What is fetal presentation
The fetal part that enters the pelvic inlet first and leads through the birth canal during labor
What is cephalic presentation
The fetal head will be the first to come into contact with the maternal cervix
What are three advantages of cephalic presentation?
1. Fetal head is largest part. Once head is delivered the rest of the body usually delivers without issue
2. The fetal head is capable of molding. helps the fetus maneuver through the maternal birth passage
3. The fetal head is smooth and round which is the optimal shape to apply pressure to the cervix and aid
in dilation
, What are the 4 types of cephalic presentations?
1. Vertex
2. Military
3. Brow
4. Face
What is vertex presentation
the fetal head presents fully flexed. This is the most frequent and optimal presentation
What is military presentation?
The fetal head presents in a neutral position , which is neither flexed nor extended. The occipitofrontal
diameter presents to the maternal pelvis and the top of the head is the presenting part
What is the brow presentation?
The fetal head is partly extended. Unstable presentation that converts to a vertex if the head flexes or to
a face presentation if the head extends
What is a face presentation?
The fetal head is fully extended and the occiput is near the fetal spine.
What is station?
The level of the presenting part in relation to the maternal ischial spines. In the normal female pelvis,
the ischial spines represent the narrowest diameter through which the fetus must mass
