Nursing OB Exam 2 Practice Questions and
Answers (100% Pass)
Labor and birth are affected by the five Ps: - Answer✔️✔️-passenger,
passageway, powers, position of the woman, and psychologic response.
The first stage of labor lasts from - Answer✔️✔️-The time dilation begins to
the time when the cervix is fully dilated.
The second stage of labor lasts from - Answer✔️✔️-The time of full cervical
dilation to the birth of the infant.
The third stage of labor lasts from - Answer✔️✔️-The infant's birth to the
expulsion of the placenta.
The fourth stage of labor - Answer✔️✔️-Is the first 2 hours after birth.
The cardinal movements of the mechanism of labor are - Answer✔️✔️-
engagement, descent, flexion, internal rotation, extension, restitution and
external rotation, and expulsion of the infant.
A primigravida asks the nurse about signs she can look for that would
indicate that the onset of labor is getting closer. The nurse should describe:
Women usually experience a weight loss of 1 to 3 lbs. Quickening is the
perception of fetal movement by the mother, which occurs at 16 to 20
weeks of gestation. Women usually experience a burst of energy or the
nesting instinct. Passage of the mucous plug (operculum) also termed
pink/bloody show occurs as the cervix ripens.
The nurse should tell a primigravida that the definitive sign indicating that
labor has begun would be:
A) progressive uterine contractions with cervical change.
B) lightening.
C) rupture of membranes.
D) passage of the mucous plug (operculum). - Answer✔️✔️-A) progressive
uterine contractions with cervical change.
Regular, progressive uterine contractions that increase in intensity and
frequency are the definitive sign of true labor along with cervical change.
Lightening is a premonitory sign indicating that the onset of labor is
getting closer. Rupture of membranes usually occurs during labor itself.
Passage of the mucous plug is a premonitory sign indicating that the onset
of labor is getting closer
On completion of a vaginal examination on a laboring woman, the nurse
records: 50%, 6 cm, -1. What is a correct interpretation of the data?
A) The fetal presenting part is 1 cm above the ischial spines.
B) Effacement is 4 cm from completion.
C) Dilation is 50% completed.
D) The fetus has achieved passage through the ischial spines. -
Answer✔️✔️-A) The fetal presenting part is 1 cm above the ischial spines.
Station of -1 indicates that the fetal presenting part is above the ischial
spines and has not yet passed through the pelvic inlet. Progress of
effacement is referred to by percentages, with 100% indicating full
effacement and dilation by centimeters, with 10 cm indicating full dilation.
Progress of effacement is referred to by percentages, with 100% indicating
full effacement and dilation by centimeters, with 10 cm indicating full
dilation. Passage through the ischial spines with internal rotation would be
indicated by a plus station such as +1.
In order to accurately assess the health of the mother accurately during
labor, the nurse should be aware that:
A) The woman's blood pressure increases during contractions and falls
back to prelabor normal between contractions.
B) Use of the Valsalva maneuver is encouraged during the second stage of
labor to relieve fetal hypoxia.
C) Having the woman point her toes reduces leg cramps.
D) The endogenous endorphins released during labor raise the woman's
pain threshold and produce sedation. - Answer✔️✔️-D) The endogenous
endorphins released during labor raise the woman's pain threshold and
produce sedation.
Blood pressure increases during contractions but remains somewhat
elevated between them. Use of the Valsalva maneuver is discouraged
during second stage labor because of a number of potentially unhealthy
outcomes, including fetal hypoxia. Pointing the toes can cause leg cramps,
as can the process of labor itself. In addition, physiologic anesthesia of the
perineal tissues, caused by the pressure of the presenting part, decreases
the mother's perception of pain.
The nurse knows that the second stage of labor, the descent phase, has
begun when:
A) the amniotic membranes rupture.
B) the cervix cannot be felt during a vaginal examination.
C) the woman experiences a strong urge to bear down.
D) the presenting part is below the ischial spines. - Answer✔️✔️-C) the
woman experiences a strong urge to bear down.
Rupture of membranes has no significance in determining the stage of
labor. The second stage of labor begins with full cervical dilation. During
the descent phase of the second stage of labor, the woman may experience
