UNIT 10: INDUCING AND AUGMENTING LABOR
Select the one best answer to each question (unless otherwise instructed). Record your answers on the test.
According to the Bishop scoring system (use the above table), labor induction is unlikely to be successful in a woman whose cervix is of medium consistency, 20% effaced, midline position, and 2 cm dilated, with the fetus in vertex presentation at -3 station, unless she undergoes cervical ripening .
True
False
Oxytocin dosage should be expressed in milliunits (mU) per minute delivered intravenously
True
False
Although induction of labor is done to produce the artificial onset of labor, the contraction pattern achieved should resem ble one that occurs with the spontaneous onset of labor.
True
False
For most patients, isotonic solutions are preferable to hyper tonic solutions, when oxytocin is administered intravenously.
True
False
Six or more contractions within 10 minutes represents normal labor.
True
False
Induction of labor is usually appropriate in all of the following situations, except when
A. A woman has severe preeclampsia.
B. Herpes lesions are on the vulva.
C. There is prelabor rupture of membranes at 36 weeks of gestation and the pregnant woman is afebrile.
D. A fetus is post-term.
Possible complications of oxytocin infusion include all of the following, except
A. Uterine rupture
B. Fetal heart rate abnormalities
C. Tachysystole
D. Chorioamnionitis
Which of the following conditions should be ruled out before oxytocin is adminis tered for induction of labor?
A. Post-term gestation
B. Abnormal fetal presentation
C. Prelabor rupture of membranes
D. Maternal preeclampsia
Which of the following actions should you take first when uterine tachysystole occurs?
A. Administer a tocolytic drug to the woman to relax the uterus.
B. Turn the woman on her left side and give oxygen by mask .
C. Stop the oxytocin infusion.
D. Perform a cesarean delivery
When oxytocin is administered for the induction of labor, the rate of infusion should be gradually but steadily increased until
A. Delivery occurs.
B. Baseline uterine tone increases to 20 mm Hg and higher.
C. Regular contractions. lasting 90 seconds or longer, become established.
D. A contraction pattern that resembles normal labor is established.
Which of the following risks is associated with prostaglandin cervical ripening medications?
A. Neonatal sepsis
B. Cervical bleeding
C. Uterine tachysystole
D. Maternal tachycardia
Maternal hyponatremia may be accompanied by mental confusion and seizures
True
False
It is reasonable to administer oxytocin augmentation of labor for 18 to 20 hours if it is needed to achieve a normal contraction pattern.
True
False
Labor induction with oxytocin infusion should proceed simulta neously with local application of a prostaglandin preparation to ripen the cervix.
True
False
