OB Exam 1 Flashcards
What does gravida mean?

What does para mean?
Number of deliveries at 20 weeks or greater that a woman has undergone
Primiparous
Having only one pregnancy
Multiparous
Having two or more pregnancies
Grand multip
A woman who has given birth 5 or more times
Primip
A woman who is having her first baby

AROM
Artificial rupture of membranes. This term describes a rupture of the membranes by a third party, usually a midwife or obstetrician in order to induce or accelerate labor.
SROM
Spontaneous rupture of membranes. This term describes the normal, spontaneous rupture of the membranes at full term. The rupture is usually at the bottom of the uterus, over the cervix, causing a gush of fluid. (Water breaking)
Intact
Membranes are intact and have not ruptured.
Fundus
Top portion of the uterus, opposite of the cervix
Cervix
Lower portion of the uterus. Becomes dilated during labor
Dilitation
The opening or enlargement of the external cervical os
Effacement
Cervical thinning to allow the presenting fetal part to descend into the vagina.
Station
the relationship of the presenting part to the level of the maternal pelvic ischial spines. Measured in centimeters and is referred to as a minus or a plus, depending on the location above or below the ischial spines.
Ballotable
While in utero, baby bounces (like a bobber) when felt through the cervix
Engagement
The entrance of the largest diameter of the fetal presenting part (usually the fetal head) into the smallest diameter of the maternal pelvis.
Lightening
When the fetal presenting part begins to descend into the maternal pelvis.
Cephalic
Fetus presenting head first
Breech
The baby exits the pelvis feet or butt first as opposed to the normal head first.
Station
The degree of descent of the presenting part of the fetus through the maternal pelvis, as measured in relation to the ischial spines of the maternal pelvis.
Fundal height
The distance (in centimeters) measured with a tape measure from the top of the pubic bone to the top of the uterus (funds) with he client lying on her back with her knees slightly flexed.
Polyhydramnios
Excess amount of amniotic fluid
Oliogohydramnios
Too little amniotic fluid
Presentation
Refers to the body part of the fetus that enters the pelvic inlet first. (What body part is coming out first)
Ultrasound/sonogram
Use of high-frequency sound waves to visualize the fetus. Enables evaluation of structural changes to be identified early.
Amniocentesis
Amniotic fluid aspirated from the amniotic sac
Biophysical Profile (BPP)
Uses a real-time ultrasound to allow assessment of various parameters of fetal well-being. Includes: Ultrasound monitoring of fetal movements, fetal tone, fetal breathing, and ultrasound assessment of amniotic fluid volume. May also include assessment of the fetal heart rate.
Induction
A procedure used to stimulate uterine contractions during pregnancy before labor begins on its own
Augmentation
Stimulating contractions. If labor isn’t progressing very well, a healthcare practitioner may try to help it along (or “augment” it)
NST (non-stress test)
Indirect measurement of uteroplacental function. Non-invasive procedure that looks at baby’s heart rate and movement.
CST or OCT (contraction - stress test)
A diagnostic procedure performed to determine the fetal heart rate response under stress, such as during contractions.
Macrosomia
Newborn with an excessive birth weight ( 8 lbs 3 ops or greater)
Microsomia
Newborn with a very low birth weight
EDC (Estimated date of confinement) or EDD (Estimated due date)
Estimated delivery date for a pregnant woman
LMP (Last menstrual period)
A woman last menstrual period. Pregnancies are dated in weeks starting from the first day of a woman’s last menstrual period.
Nagele’s Rule
Used to establish the EDB. Subtract 3 months rom the month of her LMP and then add 7 days to the first day of the LMP. Then correct the year by adding 1 to it where necessary.
