[Exam 2] Chapter 21 - Nursing Management of Labor and Birth at Risk Flashcards
(188 cards)
Dystocia: What is this?
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
Dystocia: What problems may this include during active labor?
Lack of progressive cervical dilation, lack of descent of the fetal head, or both
Dystocia: What factors are associated with increased risk for dystocia?
Epidural analgeisa, excessive analgesia, multiple pregnancy, hydramniois, maternal exhaustion, ineffective maternal pushing technique
Dystocia: Most common indications for primary cesarean births include what?
Labor dystocia, abnormal FHR tracing, fetal malpresentation, multiple gestation, and suspected macrosomia
Dystocia and Problems with Powers: What happens when the expulsive forces of the uterus become dysfunctional?
Uterus may either never fully relax (hypertonic contractions), placing fetus in jeopardy, or relax too much (hypotonic contractions) causing ineffective contractions
Dystocia and Problems with Powers: What can occur when uterus contracts so frequently?
Rapid birth will take place (precipitate labor)
Dystocia and Problems with Powers: When does hypertonic uterine dysfunction occur?
When the uterus never fully relaxes between contractions. Contractions are then ineffectual, erratic and poorly coordinated and involve only one portion of uterus.
Dystocia and Problems with Powers: What do women with a hypertonic uterine dysfunction experience?
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
Dystocia and Problems with Powers - Hypotonic Uterine Dysfunction: When does this occur?
During active labor (dilation more than 5-6 cm) when contractions become poor in quality and lack sufficient intensity to dilate and efface the cervix
Dystocia and Problems with Powers - Hypotonic Uterine Dysfunction: Factors that cause this include what?
Overstrethcing of the uterus, large fetus, multiple fetuses, hydramnios, and bowel/bladder distention prevent descent
Dystocia and Problems with Powers - Hypotonic Uterine Dysfunction: What signs may this show up as?
Weak contractions that become milder, uterine fundus thats easily distended with fingertip pressure, and contractiosn that become more infrequent and briefer.
Dystocia and Problems with Powers - Hypotonic Uterine Dysfunction: Major complication with this?
Hemorrhage after giving birth because uterus cannot contract effectively to compress blood vessels
Dystocia and Problems with Powers - Protracted Disorders: What is this?
Refers to series of events including protracted active phase of dilation (slower than normal rate of cervical dilation) and protracted descent (delayed descent of the fetal head in active phase)
Dystocia and Problems with Powers - Protracted Disorders: When will a woman be identified as having this?
A laboring woman with a slower than normal rate of cervical dilation
Dystocia and Problems with Powers - Protracted Disorders: What treatment would cause women to benefit?
Benefit from adequate hydration and some nutrition, emotional reassurance, and position changes
Dystocia and Problems with Powers - Precipitate Labor: What is this?
Labor that is completed in less than 3 hours from the start of contractions to birth.
Dystocia and Problems with Powers - Precipitate Labor: Problem with too fast of a labor?
Can result in maternal injury, and place the fetus at risk for traumatic or asphyxia insults.
Dystocia and Problems with Powers - Precipitate Labor: What would cause a woman to have this?
Those with soft perineal tissues that stretch readily, permitting the fetus to pass through pelvis quickcly, or abnormally strong uterine contractions
Dystocia and Problems with Powers - Precipitate Labor: Potential fetal complications of this?
Head trauma, such as intracranial hemorrhage or nerve damage, and hypoxia
Dystocia and Problems with Passenger: What head presentation from fetus increases probability of dystocia?
Any presentation other than occiput anterior (head down and anterior facing)
Dystocia and Problems with Passenger: Common problems involve the fetus include what?
occiput posterior position, breech presentation, multifetal pregnancy, excessive size (macrosomia)
Dystocia and Problems with Passenger - Persistent Occiput Posterior: What is this?
Most common malposition. Presents slightly larger diameters to maternal pelvis, slowing fetal descent. Poor uterine contractions may not push the fetal head down into pelvic floor
Dystocia and Problems with Passenger: Face and brow presentations are rare and associated with what?
Fetal abnormalities, pelvic contractures, high parity, placental previa, hydramnios, and low birht weight
Dystocia and Problems with Passenger: By weeks 35-36, fetuses will spontaneously settle into what presentation?
Vertix (head down, toward the birth canal)
