Intrapartum: Normal Process - Terms Flashcards
Presentation in which the fetal head is nearest the cervical opening and is born first is called?
Fetal presentation
Relation of the fetal spine to the maternal spine is called?
Fetal lie
When the maternal and fetal spines are parallel and the fetal head or breech presents, this is called?
Vertical lie
When the fetal spine is perpendicular to the maternal spine and the fetal spine presents, this is called?
Transverse lie
Body posture or position: Relation to the fetal parts while in utero, where all parts are flexed except neck is distended is called?
Fetal attitude
This is based on the sagital suture?
Fetal position
It’s the entrance of the fetal presenting part into the superior pelvis straight and the beginning of the pubic decent through the pubic canal is called?
Engagenment
This is the relationship of the fetal presenting part in an imaginary line drawn between the ishial spines of the pelvis is called?
Station
The stretching of the external os to a size large enough to allow passage of the fetus is called?
Dilatation
The thinning or shortening or obliteration of the cervix that occurs during late pregnancy, labor or both is called?
Effacement
The sensation of decreased distension of the abdomen produced by uterine decent into the pelvic cavity as the fetal presenting part settles into the pelvis is called?
Lightening
When does lightening take place?
About two weeks before the onset of labor in nulliparas.
The head of the fetus is called?
Vertex
When the chin is used as a reference point in designating fetal position it’s called?
Mentum
The largest transverse diameter of the fetal head; extends from one parietal bone to the other is called?
Bi-parietal diameter
Presentation where the buttocks or feet are nearest to the cervical opening and are born first is called?
Breech
Over lapping of the cranial bones or shaping of the fetal head to accommodate the birthing process is called?
Molding
Regional anesthesia produced by injection of a local anesthetic into the epidural space is called?
Epidural
The stage of birth where the fetal head can be seen at the vaginal orifice as the widest part of the head distends the vulva is called?
Crowning
Four maneuvers to diagnose fetal position by external palpation of the maternal abdomen is called?
Leopold’s maneuver
What type of deceleration is caused by cord compression?
Variable deceleration
What type of deceleration is caused by uteroplacental insufficiency?
Late deceleration
What type of deceleration is caused by fetal head compression?
Early deceleraton
What is the normal range of the FHR?
110 - 160 bpm
This stage of labor begins with the onset of regular uterine contractions and ends with full cervical effacement and dilation.
The first stage of labor
What are the three phases of labor?
The first stage of labor consists of three phases: the latent phase, the active phase and the transition phase.
The latent phase consists of what range of cervical dilation?
0 through 3 cm of dilation
The active phase consists of what range of cervical dilation?
4 to 7 cm of dilation
The transitional phase consists of what range of cervical dilation?
8 to 10 cm of dilation
The second stage of labor is composed of what two phases? Uterine activity, the urge to bear down, and fetal descent characterize these phases.
The latent phase and the active pushing (descent) phase.
What does the third phase of labor consist of?
From the birth of the baby to the expulsion of the placenta.
This labor curve shows a pattern of decent of the presenting part and dilation of the cervix is called?
Friedman curve
The involuntary rthymic tightening of the uterine muscle that acts to expel the fetus and placenta from the uterus is called?
Contraction
The period of time from the beginning of a contraction to the end of the contraction is called?
Duration
The period of time from the beginning of one contraction to the beginning of another is called?
Frequency
The strength of a contraction at it’s peak is called?
Intensity
