B. maternal blood pressure.
C. maternal pulse.
D. fetal heart rate variability.

ans:c
Correct
With interruption of the membrane barrier, vaginal organisms have free access to the uterine cavity and may cause chorioamnionitis. Assessing the maternal temperature every 2 to 4 hours will be necessary to monitor for signs of infection.

A. Maternal blood pressure
B. Maternal pulse

The uterine resting tone should have at least 30 seconds between contractions. This woman has a resting time of 20 seconds. The fetal heart rate and variability show no compromise at this time; however, hypertonic contractions can lead to de

Amniotomy may be used to stimulate labor that slows after it is established.

A 39-week-gestation gravida 1 is 6 cm dilated. Membranes are intact. The labor contractions have decreased in intensity, and she has not dilated in the past 2 hours. A diagnosis of hypotonic dysfunctional labor has been made. The nurse can anticipate whic

Correct
Epidural analgesia may cause a loss of sensation, so the woman cannot feel the urge to push. The practice of laboring down, or delayed pushing�encouraging the woman to wait until she feels the reflexive urge to push�has shown a lower inciden

A woman has reached 10 cm and is attempting to push. She had an epidural and is unable to feel the urge to push. The nurse can best assist her by

B. letting her labor down, that is delaying push

ans:c
Correct
During shoulder dystocia, the shoulders of the fetus are pushed hard against the symphysis and fractures of the clavicle may occur during the birth. The infant's clavicles should be checked for crepitus, deformity, and bruising, which sugges

During birth, shoulder dystocia was diagnosed. After the birth and the newborn has been stabilized, it is important for the nurse to assess the newborn for
A. hip dysplasia.
B. lung excursion.
C. fractured clavicles.
D. clubfoot.

ans:a
Correct
The hands and knees position encourages the fetus to rotate into an anterior position. This will decrease the back pain and increase the descent of the fetal head. A prone position is contraindicated with a pregnant woman. Massaging her back

A fetus is in the posterior position. The woman is complaining of back labor and the labor is prolonged. The nurse can best assist the mother with this problem by
A. placing her in a hands and knees position.
B. placing her in a prone position.
C. massagi

ans:c
Correct
Fetal heart tones are located in the upper quadrants when the fetus is in a breech presentation. A cesarean birth is usually performed for breech presentations in primigravid women to avoid complications, such as a prolapsed cord.

A gravida 1 woman who is 39 weeks of gestation and has had no prenatal care is admitted into the labor unit in early labor. During the assessment, the nurse finds the fetal heart tones in the right upper quadrant. The nurse should anticipate
A. a precipit

Correct
During labor, a full bladder is a common soft tissue obstruction. Bladder distention reduces available space in the pelvis and intensifies maternal discomfort. An epidural decreases the woman's sensation of the need to void, and the extra fl

A woman with an epidural has been pushing for the past 2 hours with very little progression. An appropriate nursing action at this point is to
A. assess for a full bladder.
B. assess for a full colon.
C. allow the woman to rest for two or three contractio

Correct
Both mother and newborn are at risk for infection during the postpartum period after premature rupture of the membranes.

A woman had premature rupture of the membranes at 37 weeks of gestation. She went into labor within 10 hours and delivered a 7 lb, 12 oz boy after a 12-hour labor. In planning care for the newborn, it is important to monitor him for
A. respiratory distres

ans:d
Correct
Calcium loss from bones can begin as early as 3 days after the onset of bed rest. Weight loss, constipation, and a decrease in plasma volume and cardiac output are associated with bed rest.

Research has found that bed rest as an intervention for preventing preterm labor can result in
A. maternal weight gain.
B. diarrhea.
C. increased maternal plasma volume and cardiac output.
D. bone demineralization, with calcium loss.

ans:a
Correct
A constant low backache is a common symptom of preterm labor. She needs to be evaluated as soon as possible. Drinking fluids has not been proven to stop preterm labor but decreases uterine irritability.

A. have the woman come in to be evaluated.
B. have the woman call back in 1 day if the backache does not improve.
