  4. Cloudy, greenish-yellow, and containing little white specks

36.  At 38 weeks’ gestation, a client is having late decelerations. The fetal pulse oximeter shows 75% to 85%. The nurse should:

  2. Discontinue the catheter, if the reading does not go below 30%
  3. Advance the catheter until the reading is above 90% and continue monitoring
  4. Reposition the catheter, recheck the reading, and if it is 55%, keep monitoring

37.  When examining the fetal monitor strip after rupture of the membranes in a laboring client, the nurse notes variable decelerations in the fetal heart rate. The nurse should:

  1. Stop the oxytocin infusion
  2. Change the client’s position
  3. Prepare for immediate delivery
  4. Take the client’s blood pressure

38.  When monitoring the fetal heart rate of a client in labor, the nurse identifies an elevation of 15 beats above the baseline rate of 135 beats per minute lasting for 15 seconds. This should be documented as:

  1. An acceleration
  2. An early elevation

  2. Effacement is 4 cm from completion
  3. Dilation is 50% completed
  4. Fetus has achieved passage through the ischial spines

53.  Which of the following findings meets the criteria of a reassuring FHR pattern?

  1. FHR does not change as a result of fetal activity
  2. Average baseline rate ranges between 100 – 140 BPM
  3. Mild late deceleration patterns occur with some contractions
  4. Variability averages between 6 – 10 BPM

54.  Late deceleration patterns are noted when assessing the monitor tracing of a woman whose labor is being induced with an infusion of Pitocin.  The woman is in a side-lying position, and her vital signs are stable and fall within a normal range.  Contractions are intense, last 90 seconds, and occur every 1 1/2 to 2 minutes. The nurse’s immediate action would be to:

  1. Change the woman’s position
  2. Stop the Pitocin
  3. Elevate the woman’s legs
  4. Administer oxygen via a tight mask at 8 to 10 liters/minute

55.  The nurse should realize that the most common and potentially harmful maternal complication of epidural anesthesia would be:

  1. Severe postpartum headache
  2. Limited perception of bladder fullness
  3. Increase in respiratory rate
  4. Hypotension

ANSWERS

  1. 4. The second stage of labor begins when the cervix is dilated completely and ends with the birth of the neonate.
  2. 3. Late decelerations are due to uteroplacental insufficiency as the result of decreased blood flow and oxygen to the fetus during the uterine contractions. This causes hypoxemia; therefore oxygen is necessary. The supine position is avoided because it decreases uterine blood flow to the fetus. The client should be turned to her side to displace pressure of the gravid uterus on the inferior vena cava. An intravenous pitocin infusion is discontinued when a late deceleration is noted.
  3. 1. A normal fetal heart rate is 120-160 beats per minute. A count of 180 beats per minute could indicate fetal distress and would warrant physician notification. By full term, a normal maternal hemoglobin range is 11-13 g/dL as a result of the hemodilution caused by an increase in plasma volume during pregnancy.
  4. 4. Vena cava and descending aorta compression by the pregnant uterus impedes blood return from the lower trunk and extremities. This leads to decreasing cardiac return, cardiac output, and blood flow to the uterus and the fetus. The best position to prevent this would be side-lying with the uterus displaced off of abdominal vessels. Positioning for abdominal surgery necessitates a supine position; however, a wedge placed under the right hip provides displacement of the uterus.
  5. 4. The nurse simultaneously should palpate the maternal radial or carotid pulse and auscultate the fetal heart rate to differentiate the two. If the fetal and maternal heart rates are similar, the nurse may mistake the maternal heart rate for the fetal heart rate. Leopold’s maneuvers may help the examiner locate the position of the fetus but will not ensure a distinction between the two rates.
  6. 2. A normal fetal heart rate is 120-160 BPM. Bradycardia or late or variable decelerations indicate fetal distress and the need to discontinue to pitocin. The goal of labor augmentation is to achieve three good-quality contractions in a 10-minute period.
  7. 2. Continuous electronic fetal monitoring should be implemented during an IV infusion of Pitocin.
  8. 4. A normal fetal heart rate is 120-160 beats per minute. Fetal bradycardia between contractions may indicate the need for immediate medical management, and the physician or nurse mid-wife needs to be notified.
  9. 1. Accelerations are transient increases in the fetal heart rate that often accompany contractions or are caused by fetal movement. Episodic accelerations are thought to be a sign of fetal-well being and adequate oxygen reserve.

10.  2. Assessing the baseline fetal heart rate is important so that abnormal variations of the baseline rate will be identified if they occur. Options 1 and 3 are important to assess, but not as the first priority.

11.  1. Station is the relationship of the presenting part to an imaginary line drawn between the ischial spines, is measured in centimeters, and is noted as a negative number above the line and a positive number below the line. At -1 station, the fetal presenting part is 1 cm above the ischial spines.

12.  4. Anemic women have a greater likelihood of cardiac decompensation during labor, postpartum infection, and poor wound healing. Anemia does not specifically present a risk for hemorrhage. Having a loud mouth is only related to the person typing up this test.

13.  4. As the placenta separates, it settles downward into the lower uterine segment. The umbilical cord lengthens, and a sudden trickle or spurt of blood appears.

14.  2. Amniotomy can be used to induce labor when the condition of the cervix is favorable (ripe) or to augment labor if the process begins to slow. Rupturing of membranes allows the fetal head to contact the cervix more directly and may increase the efficiency of contractions.

15.  2. Variable decelerations occur if the umbilical cord becomes compressed, thus reducing blood flow between the placenta and the fetus. Early decelerations result from pressure on the fetal head during a contraction. Late decelerations are an ominous pattern in labor because it suggests uteroplacental insufficiency during a contraction. Short-term variability refers to the beat-to-beat range in the fetal heart rate.

16.  2. Effleurage is a specific type of cutaneous stimulation involving light stroking of the abdomen and is used before transition to promote relaxation and relieve mild to moderate pain. Effleurage provides tactile stimulation to the fetus.

17.  2. Pains, helplessness, panicking, and fear of losing control are possible behaviors in the 2nd stage of labor.

18.  1, 4, 2. 5, 3. If uterine hypertonicity occurs, the nurse immediately would intervene to reduce uterine activity and increase fetal oxygenation. The nurse would stop the Pitocin infusion and increase the rate of the nonadditive solution, check maternal BP for hyper or hypotension, position the woman in a side-lying position, and administer oxygen by snug face mask at 8-10 L/min. The nurse then would attempt to determine the cause of the uterine hypertonicity and perform a vaginal exam to check for prolapsed cord.

19.  3. Therapeutic management for hypotonic uterine dysfunction includes oxytocin augmentation and amniotomy to stimulate a labor that slows.

20.  2. Management of hypertonic labor depends on the cause. Relief of pain is the primary intervention to promote a normal labor pattern.

21.  3. The priority is to monitor the fetal heart rate.

22.  3. In a client with a multi-fetal pregnancy, each fetal heart rate is monitored separately.

23.  4. Because the placenta is implanted in the lower uterine segment, which does not contain the same intertwining musculature as the fundus of the uterus, this site is more prone to bleeding.

24.  4. Signs of placental separation include lengthening of the umbilical cord, a sudden gush of dark blood from the introitus (vagina), a firmly contracted uterus, and the uterus changing from a discoid (like a disk) to a globular (like a globe) shape. The client may experience vaginal fullness, but not severe uterine cramping. I am going to look more into this answer. According to our book on page 584, this is not one of our options.

25.  1. When cord prolapse occurs, prompt actions are taken to relieve cord compression and increase fetal oxygenation. The mother should be positioned with the hips higher than the head to shift the fetal presenting part toward the diaphragm. The nurse should push the call light to summon help, and other staff members should call the physician and notify the delivery room. No attempt should be made to replace the cord. The examiner, however, may place a gloved hand into the vagina and hold the presenting part off of the umbilical cord. Oxygen at 8 to 10 L/min by face mask is delivered to the mother to increase fetal oxygenation.

26.  1. DIC is a state of diffuse clotting in which clotting factors are consumed, leading to widespread bleeding. Platelets are decreased because they are consumed by the process; coagulation studies show no clot formation (and are thus normal to prolonged); and fibrin plugs may clog the microvasculature diffusely, rather than in an isolated area. The presence of petechiae, oozing from injection sites, and hematuria are signs associated with DIC. Swelling and pain in the calf of one leg are more likely to be associated with thrombophebitis.

27.  3. In abruptio placentae, acute abdominal pain is present. Uterine tenderness and pain accompanies placental abruption, especially with a central abruption and trapped blood behind the placenta. The abdomen will feel hard and boardlike on palpation as the blood penetrates the myometrium and causes uterine irritability. Observation of the fetal monitoring often reveals increased uterine resting tone, caused by failure of the uterus to relax in attempt to constrict blood vessels and control bleeding.

28.  3. Manual pelvic examinations are contraindicated when vaginal bleeding is apparent in the 3rd trimester until a diagnosis is made and placental previa is ruled out. Digital examination of the cervix can lead to maternal and fetal hemorrhage. A diagnosis of placenta previa is made by ultrasound. The H/H levels are monitored, and external electronic fetal heart rate monitoring is initiated. External fetal monitoring is crucial in evaluating the fetus that is at risk for severe hypoxia.

29.  2. The goal of management in abruptio placentae is to control the hemorrhage and deliver the fetus as soon as possible. Delivery is the treatment of choice if the fetus is at term gestation or if the bleeding is moderate to severe and the mother or fetus is in jeopardy.

30.  2. Excessive fundal pressure, forceps delivery, violent bearing down efforts, tumultuous labor, and shoulder dystocia can place a woman at risk for traumatic uterine rupture. Hypotonic contractions and weak bearing down efforts do not alone add to the risk of rupture because they do not add to the stress on the uterine wall.

31.  1. Determining the fetal well-being supersedes all other measures. If the FHR is absent or persistently decelerating, immediate intervention is required.

32.  3. A station of +1 indicates that the fetal head is 1 cm below the ischial spines.

33.  3. Fetal heart tones are best auscultated through the fetal back; because the position is ROP (right occiput presenting), the back would be below the umbilicus and on the right side.

34.  3. This is the way to determine the frequency of the contractions

35.  3. by 36 weeks’ gestation, normal amniotic fluid is colorless with small particles of vernix caseosa present.

36.  4. Adjusting the catheter would be indicated. Normal fetal pulse oximetry should be between 30% and 70%. 75% to 85% would indicate maternal readings.

37.  2. Variable decelerations usually are seen as a result of cord compression; a change of position will relieve pressure on the cord.

38.  1. An acceleration is an abrupt elevation above the baseline of 15 beats per minute for 15 seconds; if the acceleration persists for more than 10 minutes it is considered a change in baseline rate. A tachycardic FHR is above 160 beats per minute.

39.  4. A persistent occiput-posterior position causes intense back pain because of fetal compression of the sacral nerves. Occiput anterior is the most common fetal position and does not cause back pain.

40.  1. Blowing forcefully through the mouth controls the strong urge to push and allows for a more controlled birth of the head.

41.  2. Uterine tetany could result from the use of oxytocin to induce labor. Because oxytocin promotes powerful uterine contractions, uterine tetany may occur. The oxytocin infusion must be stopped to prevent uterine rupture and fetal compromise.

42.  4. Gentle pressure is applied to the baby’s head as it emerges so it is not born too rapidly. The head is never held back, and it should be supported as it emerges so there will be no vaginal lacerations. It is impossible to push and pant at the same time.

43.  1. A pudendal block provides anesthesia to the perineum.

44.  1. A fetal scalp pH below 7.25 indicates acidosis and fetal hypoxia.

45.  1. Vertex presentation (flexion of the fetal head) is the optimal presentation for passage through the birth canal. Transverse lie is an unacceptable fetal position for vaginal birth and requires a C-section. Frank breech presentation, in which the buttocks present first, can be a difficult vaginal delivery. Posterior positioning of the fetal head can make it difficult for the fetal head to pass under the maternal symphysis pubis.

46.  4. Oxygenation of the fetus may be indirectly assessed through fetal monitoring by closely examining the fetal heart rate strip. Accelerations in the fetal heart rate strip indicate good oxygenation, while decelerations in the fetal heart rate sometimes indicate poor fetal oxygenation.

47.  3. Cervical dilation occurs more rapidly during the active phase than any of the previous phases. The active phase is characterized by cervical dilation that progresses from 4 to 7 cm. The preparatory, or latent, phase begins with the onset of regular uterine contractions and ends when rapid cervical dilation begins. Transition is defined as cervical dilation beginning at 8 cm and lasting until 10 cm or complete dilation.

48.  3. A complaint of rectal pressure usually indicates a low presenting fetal part, signaling imminent delivery. The nurse should perform a pelvic examination to assess the dilation of the cervix and station of the presenting fetal part. Don’t let the client use the potty or bedpan before she is examined because she could birth that there baby right there in that darn potty.

49.  3. The five essential factors (5 P’s) are passenger (fetus), passageway (pelvis), powers (contractions), placental position and function, and psyche (psychological response of the mother).

50.  1. Presentation is the fetal body part that enters the pelvis first; it’s classified by the presenting part; the three main presentations are cephalic/occipital, breech, and shoulder. The relationship of the presenting fetal part to the maternal pelvis refers to fetal position. The relationship of the long axis to the fetus to the long axis of the mother refers to fetal lie; the three possible lies are longitudinal, transverse, and oblique.

51.  3. Uterine rupture is a medical emergency that may occur before or during labor. Signs and symptoms typically include abdominal pain that may ease after uterine rupture, vomiting, vaginal bleeding, hypovolemic shock, and fetal distress. With placental abruption, the client typically complains of vaginal bleeding and constant abdominal pain.

52.  1. Station of – 1 indicates that the fetal presenting part is above the ischial spines and has not yet passed through the pelvic inlet.  A station of zero would indicate that the presenting part has passed through the inlet and is at the level of the ischial spines or is engaged.  Passage through the ischial spines with internal rotation would be indicated by a plus station, such as + 1.  Progress of effacement is referred to by percentages with 100% indicating full effacement and dilation by centimeters (cm) with 10 cm indicating full dilation.

53.  4. Variability indicates a well oxygenated fetus with a functioning autonomic nervous system. FHR should accelerate with fetal movement.  Baseline range for the FHR is 120 to 160 beats per minute.  Late deceleration patterns are never reassuring, though early and mild variable decelerations are expected, reassuring findings.

54.  2. Late deceleration patterns noted are most likely related to alteration in uteroplacental perfusion associated with the strong contractions described. The immediate action would be to stop the Pitocin infusion since Pitocin is an oxytocic which stimulates the uterus to contract. The woman is already in an appropriate position for uteroplacental perfusion. Elevation of her legs would be appropriate if hypotension were present. Oxygen is appropriate but not the immediate action.

55.  4. Epidural anesthesia can lead to vasodilation and a drop in blood pressure that could interfere with adequate placental perfusion.  The woman must be well hydrated before and during epidural anesthesia to prevent this problem and maintain an adequate blood pressure.  Headache is not a side effect since the spinal fluid is not disturbed by this anesthetic as it would be with a low spinal (saddle block) anesthetic; 2 is an effect of epidural anesthesia but is not the most harmful.  Respiratory depression is a potentially serious complication.

  18. You really make it appear really easy with your presentation but I find this
    topic to be really something that I believe I might never understand.
    It kind of feels too complicated and very wide for me.
    I am taking a look ahead for your next post,
    I will attempt to get the dangle of it!
