Q

Dystocia: What is this?

A

Defined as abnormal or difficult labor, and can be influenced by a vast number of maternal and fetal factors. Said to exist when progress of labor deviates from normal and is a slow/abnormal progression of labor

Q

Dystocia and Problems with Powers: What happens when the expulsive forces of the uterus become dysfunctional?

A

Uterus may either never fully relax (hypertonic contractions), placing fetus in jeopardy, or relax too much (hypotonic contractions) causing ineffective contractions

Q

Dystocia and Problems with Powers: When does hypertonic uterine dysfunction occur?

A

When the uterus never fully relaxes between contractions. Contractions are then ineffectual, erratic and poorly coordinated and involve only one portion of uterus.

Q

Dystocia and Problems with Powers: What do women with a hypertonic uterine dysfunction experience?

A

A prolonged latent phase, stay at 2-3 cm, and do not dilate as they should . Placental perfusion becomes compromised, thereby reducing oxygen to fetus

Q

Dystocia and Problems with Powers - Hypotonic Uterine Dysfunction: When does this occur?

Q

Postterm Pregnancy: Maternal risks for this?

A

RElated to large size, which increases C-SEction risk. Dystocia, birth trauma, and postpartum hemorrhage may occur

77
Q

Postterm Pregnancy: What mechanical or artifical interventions may be necessary?

A

Forceps or vacuum-assisted birth and labor induction with oxytocin

78
Q

Postterm Pregnancy: Fetal risks associated with this include

A

Macrosomia, shoulder dystocia, brachial plexus injuries, low Apgar scores and postmaturity syndrome

79
Q

Postterm Pregnancy: What happens as placenta ages?

A

Perfusion decreases and it becomes less efficient at delievering oxygen and nutrients to fetus. Amniotic fluid volume also declines.

80
Q

Postterm Pregnancy: When expectant management is chosen, the nurse should anticipate that assessments for this will include

A

daily fetal movement counts done by woman, nonstress tests with amniotic fluid assessments as part of biophysical profile done twice weekly.

81
Q

Postterm Pregnancy - Providing Care During the Intrapartum Period: What should you assess here?

A

Continuously assess and monitor FHR to identify potential fetal distress.

82
Q

Postterm Pregnancy - Providing Care During the Intrapartum Period: Why should amniotic fluid characteristics be monitored when membranes rupture?

A

To identify previous fetal hypoxia and prepare for prevention of meconium aspiration.

83
Q

Postterm Pregnancy - Providing Care During the Intrapartum Period: Amniofusion may be needed to minimize risk of what?

A

Meconium aspiration by diluting the meconium in the amniotic fluid expelled by the hypoxic fetus.

84
Q

Women Requiring Labor Induction and Augmentation: What is Labor Induction?

A

Involves stimulation of uterine contractions by medical or surgical means before the onset of spontaneous labor

85
Q

Women Requiring Labor Induction and Augmentation: What else does labor induction also involve?

A

IV therapy, bed rest, continuous electronic fetal monitoring, and significant discomfort from stimulating uterine contractions

86
Q

Women Requiring Labor Induction and Augmentation: Why may a woman induce labor?

A

PROM, Gestational Hypertension, Cardaic Disease, REnal Disease, Dystotcia, and Intrauterine FEtal Demise.

87
Q

Women Requiring Labor Induction and Augmentation: Contraindications for this?

A

Complete placenta previa, abruptio placentae, transverse lie, prolapsed umbilical cord.

88
Q

Women Requiring Labor Induction and Augmentation - Therapeutic Mx: The decision to induce labor is usuallybased on what?

A

Ultrasound to evaluate fetal size, position, and gestational age.

Engaged Presenting Fetal PArt

Nonstress test to evaluate fetal well-being.

89
Q

Women Requiring Labor Induction and Augmentation - Therapeutic Mx and Cervical Ripening: What is htis?

A

Process by which the cervix softens via the breakdwon of colalgen fibrils. This is so cervix ix 50% effaced and 2cm dilated at onset of labor.

90
Q

Women Requiring Labor Induction and Augmentation - Therapeutic Mx and Cervical Ripening: Difference between a ripe and unripe cervix?

A

Ripe: Shortened, centered, softened, and partially dilated

Unripe: Long, closed, posterior, and firm

91
Q

Women Requiring Labor Induction and Augmentation - Therapeutic Mx and Cervical Ripening: What does a score over 8 indicate for Bishop score?

A

Successful vaginal birth

92
Q

Women Requiring Labor Induction and Augmentation - Therapeutic Mx and Cervical Ripening: Bishop scores less than 6 usually indicate what?

A

That cervical ripening method should beused prior to induction.

93
Q

Women Requiring Labor Induction and Augmentation - Therapeutic Mx and Cervical Ripening: Medical induction of labor has what two components?

A

Cervical ripening and induction of contractions.

94
Q

Women Requiring Labor Induction and Augmentation - Cervical Ripening and Complementary/Alt Medicine Method: What other methods can be used here?

A

Herbal agents such as evening primose oil, black haw, black and blue cohosh, and red rasberry leaves

Castor oil and hot baths can be used as well

95
Q

Women Requiring Labor Induction and Augmentation - Cervical Ripening and Complementary/Alt Medicine Method: Why can sex be beneficial?

A

Promotes release of oxytocin which stimulates uterine contractions. Human semen also stimulates prostaglandins

96
Q

Women Requiring Labor Induction and Augmentation - Cervical Ripening and Mechanical Methods: How does this work?

A

Application of local pressure stimulates the release of prostaglandins to ripen the cervix.

97
Q

Women Requiring Labor Induction and Augmentation - Cervical Ripening and Mechanical Methods: Risks associated with these?

A

Infection, bleeding, membrane rupture, and placental disruption.
