ANS: B
The gynecoid pelvis is round and cylinder-shaped, with a wide pubic arch and is considered the most suitable for a vaginal birth. An android pelvis has been described as heart shaped, with more prominent ischial spines and a narrow pubic arch. A vaginal birth will be more difficult, with the need for harder pushing and often some form of instrumentation. The anthropoid pelvis is a long narrow oval, with a narrow pubic arch. It is more favorable than the android or platypelloid pelvic shape. The platypelloid pelvis is flat, wide, short, and oval and has a very poor prognosis for vaginal birth. Most women have characteristics from two or more types of pelvic shapes.
ANS: B
Bacterial growth prefers a moist, warm environment. Use an aseptic technique if membranes are not ruptured; use a sterile technique if membranes are ruptured. Vaginal drainage should be removed with a front to back motion to decrease fecal contamination. Vaginal examinations should be limited to decrease transmission of vaginal organisms into the uterine cavity.
ANS: C
Amniotic fluid should be clear and have a mild odor, if any. Fetal tachycardia of greater than 160 beats/minute is often the first sign of intrauterine infection. A temperature of 38C (100.4F) or higher is a classic symptom of infection. Vital signs should be assessed hourly to identify tachycardia or tachypnea, which often accompany temperature elevation.
ANS: B
A prolapsed cord may not be visible but may be palpated on vaginal examination. The priority is to relieve pressure on the umbilical cord. Leopold maneuvers are not an appropriate action at this time. Moist towels retard cooling and drying of the prolapsed cord, but it is hoped the fetus will be delivered before this occurs. The high Fowler position will increase cord compression and decrease fetal oxygenation.
ANS: B
Lying supine increases the discomfort of back labor. Squatting aids rotation and fetal descent. A sitting or kneeling position may help the fetal head to rotate to occiput anterior. Rocking the pelvis encourages rotation from occiput posterior to occiput anterior.
ANS: A
Birth for the nulliparous patient with a fetus in breech presentation is almost always cesarean birth. The greatest fetal risk in the vaginal birth of breech presentation is that the head (largest part of the fetus) is the last to be delivered. The birth of the rest of the baby must be quick so the infant can breathe. Serious trauma to maternal or fetal tissues is likely if the vacuum extractor birth is difficult. Most breech births are difficult. The health care provider may assist rotation of the head with forceps. A cesarean birth may be required.
ANS: D
Overdistention of the uterus in a multiple pregnancy is associated with hypotonic dysfunction because the stretched uterine muscle contracts poorly. A young primigravida usually will have good muscle tone in the uterus. This prevents hypotonic dysfunction. There is no indication that this patient’s uterus is overdistended, which is the main cause of hypotonic dysfunction. A primigravida usually will have good uterine muscle tone, and there is no indication of an overdistended uterus.
ANS: A
A high uterine resting tone, with inadequate relaxation between contractions, reduces maternal blood flow to the placenta and decreases the fetal oxygen supply. Maternal fatigue usually does not decrease uterine blood flow. Maternal sedation will sedate the fetus but should not decrease blood flow. Tocolytic drugs decrease contractions. This will increase uterine blood flow.
ANS: A
Because of the shoulder dystocia, the infant’s clavicles may have been fractured. Palpation is a simple assessment to identify crepitus or deformity that requires follow-up. The infant needs to be assessed for clavicle fractures before excessive movement. A complete newborn assessment is necessary for all newborns, but assessment of the clavicle is top priority for this infant. The Apgar indicates that no respiratory interventions are needed.
ANS: D
Intervention is needed to manage the dysfunctional pattern. Offering support and comfort is important to help the patient cope with the situation, no matter at what stage. It is important to get her into a more comfortable position and fetal monitoring should continue. An alteration in breathing pattern will not decrease the pain in this situation.
ANS: D
The priority is to relieve pressure on the cord. Changing the maternal position will shift the position of the fetus so that the cord is not compressed. Notifying the health care provider is a priority but not the first action. It would not be appropriate to apply a scalp electrode at this time. Preparing the mother for a cesarean birth would not be the first priority. The nurse may need to hold the presenting part away from the cord until delivery is complete.
ANS: A
Pain between the scapulae may occur when the uterus ruptures because blood accumulates under the diaphragm. This is an emergency that requires medical intervention. Observing for high uterine resting tones should have been done before the sudden pain. High uterine resting tones put the patient at high risk for uterine rupture. The patient is now at high risk for shock. Nonadditive intravenous fluids should be increased. Repositioning the patient with her hips slightly elevated is the treatment for a prolapsed cord. That position in this scenario would cause respiratory difficulties.
ANS: C
Because the fetal presenting part is positioned high in the pelvis and is not well applied to the cervix, a prolapsed cord could occur if the membranes rupture. Hydramnios puts the patient at high risk for a prolapsed umbilical cord. A very small fetus, normally preterm, puts the patient at risk for a prolapsed umbilical cord. Meconium-stained amniotic fluid shows that the fetus already has been compromised but does not increase the chance of a prolapsed cord.
ANS: B
After the fetal legs and trunk emerge from the patient’s vagina, the umbilical cord can be compressed between the maternal pelvis and the fetal head if a delay occurs in the birth of the head. The head is the largest part of a fetus. Internal rotation can occur with a breech. There is no relationship between breech presentation and postpartum hemorrhage.
ANS: A
A prolonged backache is one of the subtle symptoms of preterm labor. Early intervention may prevent preterm birth. The patient needs to be assessed for preterm labor before providing pain relief.
ANS: D
All assessments are important; however, those most relevant to tocolytic therapy include the fetal heart rate and maternal pulse, which tend to increase, and the maternal blood pressure, which tends to exhibit a wide pulse pressure. Intake and output and glucose are not important assessments to monitor for side effects of terbutaline. Internal temperature and odor of amniotic fluid are important if the membranes have ruptured; however, these are not relevant to the medication.
ANS: D
A large rupture of the uterus will disrupt its ability to contract. Fetal tachycardia is a sign of hypoxia. With a large rupture, the nurse should be alert for the earlier signs. Dyspnea is not an early sign of a rupture. Contractions will stop with a rupture
ANS: D
The administration of an epidural may help relieve increased uterine resting tone by decreasing maternal pain sensation. Hypertonic labor pattern indicates increased uterine resting tone; therefore augmentation would not be advised at this time because it would cause further uterine irritation in the form of contractions. Rupture of membranes would not be warranted at this time because the critical issue is to resolve the increased uterine resting tone. There is no indication that a vaginal exam is required at this time based on the information provided.
ANS: B
In the presence of a suspected shoulder dystocia, a surgical birth method is typically indicated to avoid complications from this type of abnormal presentation. Fundal pressure is no longer recommended as a treatment strategy because it may cause additional problems. Vacuum extraction will not help to resolve the birth issue and may lead to further complications. Repositioning of the patient may not be effective to relieve this condition and facilitate birth.
ANS: C
Fetal fibronectin testing has a predictive value relative to the onset of preterm labor. A specimen is collected from the vaginal area. False-positive results can occur in response to excessive cervical manipulation, in the presence of bleeding, and as a result of sexual activity.
ANS: D
A long-term goal is based on acknowledgment of prescribed clinical treatment conditions for the specified timeframe. Planning for caregiving for the next week or month provide evidence of short-term goals. It is not realistic for the patient to take care of her children at home with rest period because the patient will not be maintaining the prescribed therapy regimen and thus may be at risk to further develop complications.
ANS: C
The presence of CPD is a contraindication for vaginal birth. To prevent further complications, the patient should be prepped for a cesarean section.
ANS: B
Anaphylactoid syndrome was previously known as amniotic fluid embolism. This is a rare complication that results in a medical emergency in which CPR measures are initiated and mechanical ventilation, correction of shock and hypotension, and blood component therapy are also begun. Meconium-stained fluid is associated with particulate matter that may be found in the maternal circulation. Internal fetal monitoring may provide a potential source of entry because it is an invasive procedure. The use of nebulizers is not indicated. The patient with this condition will be hypotensive, not hypertensive.
ANS: B
The most serious concern related to a postdate pregnancy is that of fetal compromise based on the fact that the placenta function deteriorates. Although one can appreciate that the patient wants to have a natural labor experience, some women do not go into labor for various physiologic reasons. Therefore it is best for the patient to remain in a supervised clinical setting. Indicating that the patient could possibly go home would place the patient at risk and the nurse at risk for practicing outside of his or her scope of practice. Even though there can be a difference in the calculated due date, it is highly unlikely that the pregnancy has gone longer than 42 weeks.
