Components of Labor Pt.2

Question 1

describes the degree of flexion a fetus assumes
during labor or the relation of the fetal parts to each other.

Answer 1

Fetal ATTITUDE

Question 2

the relationship between the long (cephalocaudal) axis of the
fetal body and the long axis of a woman’s body

Answer 2

Fetal LIE

Question 3

denotes the body part that will first
contact the cervix or be born first and is determined by the combination of fetal lie
and the degree of fetal flexion (attitude)

Answer 3

Fetal PRESENTATION

Question 4

the relationship of the presenting part to a specific
quadrant and side of a woman’s pelvis

Answer 4

Fetal POSITION:

Question 5

a fetus in good attitude; the fetal
head flexes so sharply that the chin
rests on the chest;
suboccipitobregmatic, presents to
the birth canal

Answer 5

Complete (Full) Flexion:

Question 6

the chin is not touching the chest
but is in alert or “military position”;
the occipitofrontal diameter
presents.

Answer 6

Moderate Flexion:

Question 7

poor flexion; the back is arched and
the neck is extended, presenting the
occipitomental diameter (the largest
diameter) of the head to the birth
canal presents.

Answer 7

Complete Extension:

Question 8

horizontal

Answer 8

Transverse Lie

Question 9

(vertical);
- (cephalic) the fetal
head will be the first
part to contact the
cervix, or
- (breech) with a
foot of the buttocks
as the first to
contact the cervix.

Answer 9

 Longitudinal Lie

Question 10

The most common presentation; allows the
suboccipitobregmatic diameter to present to
the cervix.

Answer 10

Vertex (Good Full Flexion)

Question 11

 The head is moderately flexed, the brow or the
sinciput becomes the presenting part.

Answer 11

Nrow (Moderate Military)

Question 14

 The fetus has extended the head to make the
face the presenting part. From this position ,
extreme edema and distortion of the face may
occur.

Answer 14

Face (Poor)

Question 15

The fetus has completely hyperextended the
head to present the chin, causing the
presenting diameter (occipitomental) to be so
wide that vagina birth may not be possible.

Answer 15

Mentum (Very poor)

Question 16

breech good attitude

Answer 16

brings the fetal
knees up against the fetal
abdomen.

Question 17

breech poor attitude

Answer 17

means the knees
and legs are extended

Question 18

*In a Vertex presentation, the

Answer 18

Occiput (O)
is the chosen point.

Question 19

In a Face presentation, it is the

Answer 19

Chin
(mentum [M]).

Question 20

*In a Breech presentation, it is the

Answer 20

e Sacrum
(Sa).

Question 21

*In a Shoulder presentation, it is the

Answer 21

Scapula or the Acromion process (A).

Question 22

may be
more painful for
a woman because
the rotation of
the fetal head
puts pressure on
the sacral nerves.

Answer 22

ROP OR LOP

Question 23

refers to the relationship of the presenting part of the fetus to the level of ischial spines, the
midpoint and bony projections of the lower pelvis. It measures how far the presenting part has
descended into the pelvis

Answer 23

Station

Question 24

indicate that the head is
above the ischial spines.

Answer 24

negative (-)

Question 25

numbers indicate its head is below the ischial spines.

Answer 25

positive (+)

Question 26

refers to the settling of the presenting part of a fetus far enough into the pelvis that it rests at the level of ischial spines.

Answer 26

Engagement

Question 27

At a -4 station, the presenting part or the fetal head is unengaged or

Answer 27

floating

Question 28

When the presenting part is at 0 station, its head is at the level of the ischialspines: Fetus is

Answer 28

engaged

Question 29

At a +4 station, the presenting part is at the outlet or perineum and can be seen in the vulva:

Answer 29

crowning

Question 30

of labor comes from the involuntary muscular contractions of the uterus; cause effacement and dilation of the cervix.

Answer 30

Primary Power

Question 31

are voluntary muscle contractions of the maternal abdomen during the 2nd stage of labor; aids in fetal expulsion.

Answer 31

Secondary Powers

Question 32

Building up of the contraction, is the longest phase. During the increment, the contraction gains strength until it reaches Acme.

Answer 32

Increment

Question 33

Peak of the contraction

Answer 33

Acme

Question 34

- the letting up phase, as the contraction relaxes gradually to baseline

Answer 34

Decrement

Question 35

refers to how often the contractions are occurring.

Answer 35

Frequency

Question 36

refers to the interval from the beginning of a contraction to its end

Answer 36

Duration

Question 37

- refers to the strength of the contraction. : Mild, moderate, strong.

Answer 37

Intensity

Question 38

(resting) period in between uterine contraction

Answer 38

relaxation

Question 39

an external strain gauge placed on the maternal abdomen which records the frequency, duration, and relaxations of each contraction.

Answer 39

Tocodynamometer

Question 39

allows the vessels to fill with oxygen-rich blood to supply the uterus and placenta.  prevents maternal muscles to not become overly fatigued and  Provide woman momentary relief from the pain of labo

Answer 39

benefits of relaxation period

Question 40

Records frequency and duration; directly measures the pressure generated by uterine contractions, via a catheter inserted into the uterine cavity.

Answer 40

Intrauterine pressure catheters

Question 41

refers to the psychological or emotional state or feelings a woman brings into labor.

Answer 41

psyche
