Ch 24: Childbirth at Risk: Labor-related complications
A woman is admitted to the birth setting in early labor. She is 3 cm dilated, -2 station, with intact membranes and FHR of 150 beats/min. Her membranes rupture spontaneously, and the FHR drops to 90 beats/min with variable decelerations. What would the initial response from the nurse be? A) Perform a vaginal exam. B) Notify the physician. C) Place the client in a left lateral position. D) Administer oxygen at 2 L per nasal cannula.
Answer: A Explanation: A) A drop in fetal heart rate accompanied by variable decelerations is consistent with a prolapsed cord. The nurse would assess for prolapsed cord via vaginal examination. B) The vaginal exam should be done before the physician is notified. C) Repositioning the client will not relieve the decreased heart rate if the cord is compromised. D) Administering oxygen will not relieve the decreased heart rate if the cord is compromised. Page Ref: 602
While caring for a client admitted to the birthing unit, the nurse suspects that the client may be experiencing a uterine rupture. Which assessment finding should the nurse expect to appear first? A) Nonreassuring fetal heart rate B) Constant abdominal pain C) Loss of fetal station D) Cessation of contractions
Answer: A Explanation: A) A nonreassuring fetal heart rate is commonly the earliest warning sign of a possible uterine rupture. B) Constant abdominal pain is a finding that may be present, but is not commonly the earliest sign of uterine rupture. C) Loss of fetal station is a finding that may be present, but is not commonly the earliest sign of uterine rupture. D) Cessation of contractions is a finding that may be present, but is not commonly the earliest sign of uterine rupture. Page Ref: 604
On assessment, a laboring client is noted to have cardiovascular and respiratory collapse and is unresponsive. What should the nurse suspect? A) An amniotic fluid embolus B) Placental abruption C) Placenta accreta D) Retained placenta
Answer: A Explanation: A) Cardiovascular and respiratory collapse are symptoms of an amniotic fluid embolus and cor pulmonale. B) Placental abruption does not have any of these symptoms. C) Placenta accreta does not have any of these symptoms. D) Retention of the placenta beyond 30 minutes after birth is termed retained placenta and does not have any of these symptoms. Page Ref: 604
What would be a normal cervical dilatation rate in a first-time mother ("primip")? A) 1.5 cm per hour B) Less than 1 cm cervical dilatation per hour C) 1 cm per hour D) Less than 0.5 cm per hour
Answer: A Explanation: A) Dilatation in a "multip" is about 1.5 cm per hour. B) Less than 1 cm cervical dilatation per hour is prolonged labor. C) Cervical dilatation in a first-time mother is just over 1 cm per hour. D) Dystocia is a rate of cervical dilatation of less than 0.5 cm per hour. Page Ref. 585
The client gave birth to a 7 pound, 14 ounce female 30 minutes ago. The placenta has not yet delivered. Manual removal of the placenta is planned. What should the nurse prepare to do? A) Start an IV of lactated Ringer's. B) Apply anti-embolism stockings. C) Bottle-feed the infant. D) Send the placenta to pathology.
Answer: A Explanation: A) In women who do not have an epidural in place, intravenous sedation may be required because of the discomfort caused by the procedure. An IV is necessary. B) Anti-embolism stockings are used after major surgery that leads to immobility, thus increasing the risk of embolism. However, anti-embolism stockings are not needed for this client. C) The client's partner or family member, or a nursery nurse, can feed the infant. Preparation for manual removal of the placenta is a higher priority at this time. D) The placenta might be sent to pathology after it is removed, but preparing the client for manual removal of the placenta now is a higher priority. Page Ref: 606
A woman has been having contractions since 4 a.m. At 8 a.m., her cervix is dilated to 5 cm. Contractions are frequent, and mild to moderate in intensity. Cephalopelvic disproportion (CPD) has been ruled out. After giving the mother some sedation so she can rest, what would the nurse anticipate preparing for? A) Oxytocin induction of labor B) Amnioinfusion C) Increased intravenous infusion D) Cesarean section
Answer: A Explanation: A) Oxytocin is the drug of choice for labor augmentation or labor induction and may be administered as needed for hypotonic labor patterns. B) Amnioinfusion would not change the ineffective labor pattern. C) Increasing the I V infusion would not change the ineffective labor pattern. D) Because C P D has been ruled out, a cesarean section is not anticipated. Page Ref. 586
The nurse is performing a vaginal exam on a client who was admitted to the birthing unit after her membranes ruptured, and discovers a cord prolapse. Which intervention is priority at this time? A) Pushing the presenting fetal part upward B) Administering oxygen C) Initiating intravenous fluid D) Inserting an indwelling bladder catheter
Answer: A Explanation: A) Pushing the presenting fetal part upward is a life-saving measure that relieves pressure on the umbilical cord and supports fetal gas exchange. B) Administering oxygen is performed, but at a later time. C) Initiating intravenous fluid is performed, but at a later time. D) Inserting an indwelling bladder catheter may be later used to fill the woman's bladder and relieve pressure on the umbilical cord, but this should not be done in place of pushing the presenting fetal part upward. Page Ref: 603
While performing a uterine assessment on a client in the birthing unit, the nurse notes a loss of fetal station and a change in uterine shape.

Answer: A Explanation: A) The assessment findings are consistent with uterine rupture, which may also include a nonreassuring fetal heart rate, hematuria, and cessation of contractions. B) Anaphylactoid syndrome of pregnancy is characterized by shortness of breath, hypoxia, cyanosis, and cardiovascular and respiratory collapse. C) Circumvallate placenta may result in antepartum hemorrhage, prematurity, and abnormal bleeding during or following the third stage of labor. D) Assessment findings consistent with breech presentation include palpation of the fetal sacrum in the lower part of the maternal abdomen and fetal heart tones present above the umbilicus on auscultation. Page Ref: 604

B) This assessment is not called for at this time. C) Pain medication is a low priority at this time. D) Checking the cervix will determine whether the cord prolapsed when the membranes ruptured. The nurse would assess for prolapsed cord via vaginal examination. Page Ref: 602
The multiparous client at term has arrived to the labor and delivery unit in active labor with intact membranes. Leopold maneuvers indicate the fetus is in a transverse lie with a shoulder presentation. Which physician order is most important? A) Artificially rupture membranes. B) Apply internal fetal scalp electrode. C) Monitor maternal blood pressure every 15 minutes. D) Alert surgical team of urgent cesarean.
Answer: D Explanation: A) Artificial rupture of the membranes is contraindicated with a transverse lie because of the high risk for prolapsed cord. B) An internal fetal scalp electrode cannot be applied until membranes have ruptured. C) The fetus is at risk for hypoxia secondary to prolapsed cord if the membranes rupture. The maternal blood pressure is less important than getting the cesarean under way. D) This is the highest priority because vaginal birth is impossible with a transverse lie. Labor should not be allowed to continue, and a cesarean birth should be done quickly. Page Ref: 596
The nurse examines the client's placenta and finds that the umbilical cord is inserted at the placental margin. The client comments that the placenta and cord look different than they did for her first two births. The nurse should explain that this variation in placenta and cord is called what?

Answer: D Explanation: A) In placenta accreta, the chorionic villi attach directly to the myometrium of the uterus. B) A circumvallate placenta has a double fold of chorion and amnion that form a ring around the umbilical cord, on the fetal side of the placenta. C) In succenturiate placenta, one or more accessory lobes of fetal villi will develop on the placenta. D) In battledore placenta, the umbilical cord is inserted at or near the placental margin. Page Ref: 600
After delivery, it is determined that there is a placenta accreta. Which intervention should the nurse anticipate? A) 2 L oxygen by mask B) Intravenous antibiotics C) Intravenous oxytocin D) Hysterectomy
Answer: D Explanation: A) Use of oxygen will not assist in the separation of the placenta. B) Use of intravenous antibiotics will not assist in the separation of the placenta. C) Use of intravenous oxytocin will not assist in the separation of the placenta. D) The primary complication of placenta accreta is maternal hemorrhage and failure of the placenta to separate following birth of the infant. An abdominal hysterectomy may be the necessary treatment, depending on the amount and depth of involvement. Page Ref: 606
A patient's placenta it is identified as having a double fold of chorion and amnion that formed a ring around the umbilical cord on the fetal side of the placenta. What should the nurse expect when examining this placenta? A) Supine B) Side-lying C) Lithotomy D) Knee-chest
Answer: D Explanation: D) The knee-chest position is used to relieve cord compression during a cord prolapse emergency. The supine, side-lying, or lithotomy positions are not beneficial to the fetus in cord prolapse. Page Ref: 603
