VN 34 Test 3 (sjvc intrapartum) Flashcards
(38 cards)
1a. Explain what the “Bishop Score” is. (pg.218)
How the health care provider determines cervical readiness
1b. What are the 5 bishop categories, and what do they indicate?(pg.218)
Cervical consistency
Position
Dilation
Effacement
Fetal station
The higher the score the greater the chance that induction will be successful.
Bishop score of 6 or less indicates an “unripe,” or unfavorable cervix, and labor induction is less likely to be successful.
2a. What does it mean to “ripen” a cervix? (pg.219)
A cervix that is favorable for induction/ to hasten cervical readiness
2 b. List the mechanical methods of cervical ripening (pg.219, PP slide 4)
Membrane stripping: inserts a gloved finger through the internal cervical os and sweeps the finger 360 degrees to separate the membranes from the lower uterine segment.
Mechanical dilation of the cervix w/either a catheter or laminaria: The tip of the catheter is inserted through the cervix, and the balloon of the catheter is filled with 30 to 80 mL of sterile saline. inflated balloon rests between the internal cervical os and the amniotic sac.
>Laminaria (cervical dilators) : used to soften & dilate the cervix (made from the root of seaweed). Usually to induce abortion either therapeutic or elective for when the fetus has died in uteri.
2c. List the pharmacological methods, which one can be administered both PO and vaginally? (pg.219)
Prostaglandin E2 “Dinoprostone” (applied locally to the cervix, gel or vaginal inserts)
Prostaglandin E1 “Misoprostol” (PO & vaginally)
Describe an oxytocin induction. (pg.219)
A synthetic form of the posterior pituitary hormone that causes the uterus to contract, is the most common agent used for labor induction.
b. What should the nurse do if hyperstimulation occurs? (pg.219)
Monitor the fetal heart rate for signs of fetal distress.
Provide comfort care
Decrease environmental stimuli
>Encourage deep breathing
>Apply O2 if necessary
4a. List the different types of assisted delivery (pg.220)
Episiotomy (surgical incision made into the perineum to enlarge posterior part of vaginal opening)
Vacuum- assisted delivery
Forceps delivery
5a. Name the indications for a cesarean delivery. (pg.223)
Hx of previous cesarean (or other uterine incision)
Labor dystocia (failure to progress in labor)
Nonreassuring fetal status
Fetal malpresentation (breech)
Placenta previa
Placenta abruption
Cephalopelvic disproportion (fetal head too large to fit through pelvis)
Active vaginal herpes lesions
Prolapse of the umbilical cord
Ruptured uterus
5b. In which step of a cesarean would the LVN not participate? (pg.224)
Postoperative care in the PACU
-We may care for woman after she has sufficiently recovered from anesthesia
6a. When a client is having a planned cesarean section, what must the patient sign?
Consent form
6b. Can the paper work be signed ahead of time?
Yes
- Describe how the nurse can support her patient and the patient’s family in the event of an unplanned cesarean. (pg.232)
Include the family in any explanations
Through therapeutic communication, providing information, and a reassuring touch.
Include the woman in conversations instead of talking to other staff as though the woman is not present.
Encourage the woman to rest in-between contractions. During these rest periods, avoid conversations that are not related to the delivery
A quiet room in-between contractions can help the woman rest and therefore better cope during the intervention or contractions.
Explain procedures as you are doing them. Use short, nontechnical sentences. The woman’s anxiety may be elevated and she may not be able to process lengthy or detailed explanations. (Repeat info as needed)
Explain what sensations she can expect to experience and what procedure to expect next.
Be empathic. Acknowledge her feelings and let her know that these feelings are normal considering the situation with which she must cope.
- What is a VBAC and when is it contraindicated? (pg.231)
(Vaginal birth after cesarean)
When a woman has a classical uterine incision from a previous cesarean delivery
Placenta previa
Hx of previous uterine rupture
Lack of facilities or equipment to perform an immediate emergency cesarean
9a. Describe the signs and symptoms of a uterine rupture. (pg.231, box 11-3)
Dramatic onset of fetal bradycardia or deep variable decelerations
Reports by the woman of a “popping” sensation in her abdomen
Excessive maternal pain (can be referred pain, such as to the chest)
Unrelenting uterine contraction followed by a disorganized uterine pattern
Increased fetal station felt upon vaginal examination (e.g., station is now −3 when it has been −1)
Vaginal bleeding or increased bloody show
Easily palpable fetal parts through the abdominal wall
Signs of maternal shock
9b. In the event of uterine rupture, what is the treatment of choice? (pg.397)
Immediate cesarean delivery
10a. List the causes of labor dysfunction. (pg.385)
Problems w/the uterus (uterine dysfunction)
Maternal pelvis (cephalopelvic disproportion)
Situations involving the fetus (fetal malposition)
10b. What are the treatment for hypertonic and hypotonic labor? (pg.386)
Hypertonic treatment is to decrease or shut off the oxytocin infusion
Hypotonic labor: Augmentation w/oxytocin, if hypotonic labor causes fetal heart rate to drop PCP may order tocolytic. (substance that relaxes uterine muscle)
- List the options of interventions for a safe delivery of a client whom presents with a breech presentation and for a transverse lie. (pg.387)
Breech presentation
Most health care providers prefer to do a cesarean birth without labor or attempting a vaginal delivery.
External cephalic version (manipulating the position of the fetus while in utero)
Transverse Lie
The health care provider will either use external cephalic version to try to turn the fetus to a cephalic presentation or deliver the fetus by cesarean.
12a. What is the priority for the woman with premature rupture of membranes? (pg.388, flashcard 79)
Prepare for birth
Labor induction if birth doesn’t begin on its own
Monitor for infection?
12B. Describe the management of preterm PROM, including fetal surveillance. (pg.388)
If there are signs of infection, such as elevated maternal temperature; maternal tachycardia; cloudy, foul-smelling amniotic fluid; and uterine tenderness, the health care provider obtains cultures, starts antibiotics, and facilitates delivery regardless of gestational age.
Prophylactic antibiotics (usually ampicillin and erythromycin) may be ordered for preterm PROM.
For preterm PROM between 24 & 34 weeks, intramuscular corticosteroids are given to the mother to reduce the risk of neonatal respiratory distress syndrome, intraventricular hemorrhage, and necrotizing enterocolitis
Fetal surveillance is done at least daily. Generally, the woman performs kick counts after every meal. Daily nonstress tests may also be ordered. Frequent ultrasound examinations to measure the amount of amniotic fluid and fetal growth are also done.
- What are the guidelines for the patient who is not in true labor? (Pg.157)
After the initial assessment by the health care provider, the woman may be instructed to walk for an hour or two. Then, a vaginal examination is repeated to determine any cervical changes.
If the contractions become stronger, more regular, or if other signs of true labor occur, such as rupture of membranes (“bag of waters breaks”) or presence of bloody show (mucous vaginal discharge that is pink or brown tinged which occurs as the blood vessels in the cervix start to rupture as effacement and dilation are beginning).
14.What is the significance of a fetal fibronectin test and cervical length? (pg.389)
Examinations used to diagnose PTL include evaluation of contraction frequency, fetal fibronectin test, and measurement of cervical length.
Short cervical length w/a positive fetal fribronectin test indicates that the woman has an increased chance of delivering prematurely
- What are the signs and symptoms for preterm labor?
Signs & Symptoms: (pg.389)
The definitive diagnosis of PTL is made when uterine contractions result in cervical change.
Uterine contractions (may be painless)
Pelvic pressure
Menstrual-like cramps
Vaginal pain
Low, dull backache accompanied by vaginal discharge & bleeding
Membranes may be intact or ruptured
