NSG 222 Family Health Nursing Exam #2
Questions With Complete Solutions
True versus False Labor
True labor: contractions close together, last
longer, and more intense, consistent, and bring
about cervical change (dilation)
Factors affecting the labor process
Five P's:
- Passageway (birth canal)
- Passenger (fetus and placenta)
- Powers (contractions)
- Position (maternal)
- Psychological response
Passageway
- Gynecoid is the most optimal shape, because
inlet is round and the outlet is roomy.
- This type of pelvis allows early and complete fetal
internal rotation during labor.
Passageway: soft tissues
- Cervix: effacement, the cervix effaces (thins) to
allow the presenting fetal part to descend into the
vagina.
,- Pelvic floor muscles: help the fetus to rotate
anteriorly as it passes through the birth canal.
- Vagina: expand to accommodate the fetus
during birth.
- Issues: infections, surgeries, scar tissues can
affect these soft tissues
TAKE NOTE!
The process of cervical effacement (thinning of
cervix) and dilation is analogous to that of pulling a
turtleneck sweater over your head.

Molding
molding goes down in about 3 days
Powers (contractions)
- Causes effacement (thinning of cervix, 0-100%)
and dilation (0-10 cm)
, - Frequency, duration, intensity
- Uterine contractions are rhythmic and
intermittent, with a period of relaxation between
contractions.
- this pause restores blood flow to the uterus and
placenta, which is temporarily reduced during each
uterine contraction.
- Uterine contractions are responsible for thinning
and dilating the cervix,
- Cervical canal 2 cm in length would be described
as 0% effaced.
- Cervical canal 1 cm in length would be described
as 50% effaced.
- Cervical canal 0 cm in length would be described
as 100% effaced.
- frequency refers to how often the contractions
occur and is measured from the beginning of one
contraction to the beginning of the next
contraction.
- Duration refers to how long a contraction lasts
and is measured from the beginning of one
contraction to the end of that same contraction.
- Intensity refers to the strength of the
contraction determined by manual palpation or
