A woman is documented on the labor and birth board to be 7 cm dilated. Her family wants to know how long she will be in labor. The nurse should provide which information to the family?

"She is in active labor; she is progressing at this point and we will keep you posted." At 7 cm dilated, she is considered in the active phase of labor. There is no science that can predict the length of labor. She is progressing in labor, and it is best not to give the family a specific time frame.

The nurse is measuring a contraction from the beginning of the increment to the end of the decrement for the same contraction. The nurse would document this as which finding?

duration Duration refers to how long a contraction lasts and is measured from the beginning of the increment to the end of the decrement for the same contraction. Intensity refers to the strength of the contraction determined by manual palpation or measured by an internal intrauterine catheter. Frequency refers to how often contractions occur and is measured from the increment of one contraction to the increment of the next contraction. The peak or acme of a contraction is the highest intensity of a contraction.

A nurse is educating a group of nursing students about the molding of the fetal skull during the birth process. What would the nurse include as the usual cause of molding?

poorly ossified cranial vault Molding is an adaptive process in which there is overriding and movement of the bones of the cranial vault to adapt to the maternal pelvis. The poorly ossified bones of the cranial vault, along with loosely attached membranous attachments, allow for the process of molding in the fetal skull. The bones of the face and the base of the skull are completely ossified and united. Hence they cannot allow for movement or overriding. The membranous attachments are loosely bound to the cranial vault and not tightly, which allows for molding of the fetal skull.

A client is having a routine prenatal visit and asks the nurse what the birth education teacher meant when she used the term zero station. What is the best response by the nurse?

"The presenting part is at the true pelvis and is engaged." Zero station is when the fetus is engaged in the pelvis, or has dropped. This is an encouraging sign for the client. This sign is indicative that labor may be beginning, but there is no set time frame regarding when it will start. Labor has not started yet, and the fetus has not begun to move out of the uterus.

A nurse is performing a vaginal examination of a woman in the early stages of labor. The woman has been at 2 cm dilated for the past 2 hours, but effacement has progressed steadily. Which statement by the nurse would best encourage the client regarding her progress?

"You are still 2 cm dilated, but the cervix is thinning out nicely." Women are anxious to have frequent reports during labor, to reassure them everything is progressing well. If giving a progress report, the nurse should remember most women are aware of the word dilatation but not effacement. Therefore, just saying, "no further dilatation" is a depressing report. "You're not dilated a lot more, but a lot of thinning is happening, and that's just as important" is the same report given in a positive manner.

A fetus is assessed at 2 cm above the ischial spines. How would the nurse document the fetal station?

-2 When the presenting part is above the ischial spines, it is noted as a negative station. Since the measurement is 2 cm, the station would be -2. A 0 station indicates that the fetal presenting part is at the level of the ischial spines. Positive stations indicate that the presenting part is below the level of the ischial spines.

Assessment of a woman in labor reveals that the fetus is in a cephalic presentation and engagement has occurred. The nurse interprets this finding to indicate that the presenting part is at which station?

0 Fetal engagement signifies the entrance of the largest diameter of the fetal presenting part (usually the fetal head) into the smallest diameter of the maternal pelvis. The fetus is said to be engaged in the pelvis when the presenting part reaches 0 station.

A pregnant woman, multipara, has been in labor for several hours. She cries out that her contractions are getting harder and that she cannot do this. The client is really irritable, nauseated, annoyed, and fearful of being left alone. Considering the client's behavior, the nurse would expect the cervix to be dilated how many centimeters?

8 to 10 The reaction of the client is indicative of entering or being in the transition phase of labor, stage 1. The dilation would be 8-10 cm. Before that, when dilation is 0 to 7 cm, the client has an easier time using positive coping skills.

A client gave birth to a child 3 hours ago and noticed a triangular-shaped gap in the bones at the back of the head of her newborn. The attending nurse informs the client that it is the posterior fontanelle. The client is anxious to know when the posterior fontanelle will close. Which time span is the normal duration for the closure of the posterior fontanelle?

8 to 12 weeks The posterior fontanelle is a triangular-shaped area at the back of the skull. The nurse should inform the client that the posterior fontanelle normally closes by 8 to 12 weeks after birth, and if there is delay the primary health care provider should be notified.

The first stage of labor is often a time of introspection. In light of this, which information would guide the nurse's planning of nursing care?

A woman may spend time thinking about what is happening to her. Women need a support person with them during all stages of labor.

The nurse should initially implement which intervention when a nulliparous woman telephones the hospital to report that she is in labor?

Ask the woman to describe why she believes that she is in labor. The nurse needs further information to assist in determining if the woman is in true or false labor. She will need to ask the client questions to seek further assessment and triage information. Having her wait until membranes rupture may be dangerous, as she may give birth before reaching the hospital. She should continue fluid intake until it is determined whether or not she is in labor. She may be in false labor, and more information should be obtained before she is brought to the hospital.

Braxton Hicks contractions are termed "practice contractions" and occur throughout pregnancy. When the woman's body is getting ready to go into labor, it begins to show anticipatory signs of impending labor. Among these signs are Braxton Hicks contractions that are more frequent and stronger in intensity. What differentiates Braxton Hicks contractions from true labor?

Braxton Hicks contractions usually decrease in intensity with walking. Braxton Hicks contractions occur more frequently and are more noticeable as pregnancy approaches term. These irregular, practice contractions usually decrease in intensity with walking and position changes.

A client in her third trimester of pregnancy arrives at a health care facility with a report of cramping and low back pain; she also notes that she is urinating more frequently and that her breathing has become easier the past few days. Physical examination conducted by the nurse indicates that the client has edema of the lower extremities, along with an increase in vaginal discharge. What should the nurse do next?

Continue to monitor the client. The nurse knows that the client is experiencing lightening. Lightening occurs when the fetal presenting part begins to descend into the maternal pelvis and may occur 2 weeks or more before labor. The uterus lowers and moves into a more anterior position. The client may report increased respiratory capacity, decreased dyspnea, increased pelvic pressure, cramping, and low back pain. She may also note edema of the lower extremities as a result of the increased stasis of blood pooling, an increase in vaginal discharge, and more frequent urination. The nurse would continue to monitor the client as this is a normal progression of pregnancy.

A nurse is performing a physical assessment of a woman in labor. As part of her assessment, she examines the outer and inner surfaces of her lips. What is the best rationale for this assessment?

Detection of herpes virus infection Examine the outer and inner surfaces of her lips carefully to detect herpes lesions (pinpoint vesicles on an erythematous base). Report to her primary care provider if herpetic lesions are present anywhere because although oral lesions are invariably a type I herpes virus (common cold sores), type II (genital) herpes virus needs to be identified as this can be lethal to newborns; a woman primary health care provider may suggest the woman with oral herpes lesions take isolation precautions such as not kissing her newborn until the lesions crust. Be certain to palpate for enlargement of neck lymph nodes to detect the possibility of a respiratory infection. Inspect the mucous membrane of her mouth and the conjunctiva of her eyes for color to see if paleness suggests anemia. Auscultate the woman's lungs to be certain they are clear of rales.

A pregnant client is admitted to a maternity clinic for birth. The client wishes to adopt the kneeling position during labor. The nurse knows that which to be an advantage of adopting a kneeling position during labor?

It helps to rotate fetus in a posterior position. The advantage of adopting a kneeling position during labor is that it helps to rotate the fetus in a posterior position. Facilitating vaginal examinations, facilitating external belt adjustment, and helping the woman in labor to save energy are advantages of the back-lying maternal position.

A pregnant client is admitted to a maternity clinic for birth. Which assessment finding indicates that the client's fetus is in the transverse lie position?

Long axis of fetus is perpendicular to that of client. If the long axis of the fetus is perpendicular to that of the mother, then the client's fetus is in the transverse lie position. If the long axis of the fetus is parallel to that of the mother, the client's fetus is in the longitudinal lie position. The long axis of the fetus being at 45° or 60° to that of the client does not indicate any specific position of the fetus.

A client the nurse cares for in labor asks what causes labor to begin. Which statement is a possible explanation?

Prostaglandins may be the causative factor of labor. The cause of labor is unknown, but prostaglandin release is theoretically one of the possible causes for onset of labor. It is unknown whether progesterone, estrogen, or calcium have any effect on labor.

A nurse is assigned the task of educating a pregnant client about birth. Which nursing interventions should the nurse perform as a part of prenatal education for the client to ensure a positive birth experience? Select all that apply.

Provide the client clear information on procedures involved. Encourage the client to have a sense of mastery and self-control. Encourage the client to have a positive reaction to pregnancy. To ensure a positive birth experience for the client, the nurse should provide the client clear information on procedures involved, encourage the client to have a sense of mastery and self-control, and encourage the client to have a positive reaction to pregnancy. Instructing the client to spend some time alone is not an appropriate intervention; instead, the nurse should instruct the client to obtain positive support and avoid being alone. The client does not need to change the home environment; this does not ensure a positive birth experience.

A 32-year-old woman presents to the labor and birth suite in active labor. She is multigravida, relaxed, and talking with her husband. When examined by the nurse, the fetus is found to be in a cephalic presentation. His occiput is facing toward the front and slightly to the right of the mother's pelvis, and he is exhibiting a flexed attitude. How does the nurse document the position of the fetus?

ROA The nurse should document the fetal position in the clinical record using abbreviations. The first letter describes the side of the maternal pelvis toward which the presenting part is facing ("R" for right and "L" for left). The second letter or abbreviation indicates the reference point ("O" for occiput, "Fr" for frontum, etc.). The last part of the designation specifies whether the presenting part is facing the anterior (A) or the posterior (P) portion of the pelvis, or whether it is in a transverse (T) position.

When teaching a group of nursing students about uterine contractions, which of the following would the instructor include as a typical feature?

Retracting of the lower segment The nurse should identify retraction of the lower segment of the uterus as a feature of typical uterine contractions. As labor progresses the uterine contractions become stronger. The upper segment of the uterus contracts more actively than the lower segment. The lower segment retracts, pulling up the cervix. The upper segment thickens with time and the lower segment thins.

A pregnant client wants to know why the labor of a first-time-pregnant woman usually lasts longer than that of a woman who has already given birth once and is pregnant a second time. What explanation should the nurse offer the client?

The cervix takes around 12 to 16 hours to dilate during first pregnancy. The labor of a first-time-pregnant woman lasts longer because during the first pregnancy the cervix takes between 12 and 16 hours to dilate completely. The intensity of the Braxton Hicks contractions stays the same during the first and second pregnancies. Spontaneous rupture of membranes may occur before the onset of labor during each birth, not only during the first birth.

Labor can be indicated by which occurrence?

The client reports back pain, and the cervix is effacing and dilating. True labor is indicated when the cervix is changing. Contractions occur for weeks before true labor, and may occur close together. Contractions may also occur for a long time before true labor begins.

A pregnant woman calls her provider's office to report she thinks she is in labor. The client reports contractions have been fairly strong and at these times: 12:05, 12:10, 12:15, and 12:20. What information is gathered based on this data?

The frequency of the contractions is every 5 minutes. Based on the information, the nurse knows the contractions are regular and every 5 minutes apart. This is the only data gathered based on the information given, but it is very useful to the provider.

A client experiencing contractions presents at a health care facility. Assessment conducted by the nurse reveals that the client has been experiencing Braxton Hicks contractions. The nurse has to educate the client on the usefulness of Braxton Hicks contractions. Which role do Braxton Hicks contractions play in aiding labor?

These contractions help in softening and ripening the cervix. Braxton Hicks contractions assist in labor by ripening and softening the cervix and moving the cervix from a posterior position to an anterior position. Prostaglandin levels increase late in pregnancy secondary to elevated estrogen levels; this is not due to the occurrence of Braxton Hicks contractions. Braxton Hicks contractions do not help in bringing about oxytocin sensitivity. Occurrence of lightening, not Braxton Hicks contractions, makes maternal breathing easier.

A postbirth complete blood count (CBC) has noted an elevated white blood cell (WBC) count of 22,000/mm3. Which rationale is accurate regarding the elevated WBC count?

This is a normal variation due to the stress of labor. An elevation of WBC up to 30,000mm/3 can be normal variation for any woman after birth. This is related to the stress on her body from labor and birth. Antibiotics are not indicated as this is a normal response to intense stress. The increase in WBC is not related to cesarean birth. Retesting would be wasteful as it is known that this is a normal response to any stress.

A nurse is conducting an in-service program for staff nurses working in the labor and birth unit. The nurse is discussing ways to promote a positive birth outcome for the woman in labor. The nurse determines that additional teaching is necessary when the group identifies which measure?

allowing the woman time to be alone Positive support, not being alone, promotes a positive birth experience. Being alone can increase anxiety and fear, decreasing the woman's ability to cope. Feelings of control promote self-confidence and self-esteem, which in turn help the woman to cope with the challenges of labor. Information about procedures reduces anxiety about the unknown and fosters cooperation and self-confidence in her abilities to deal with labor. Catecholamines are secreted in response to anxiety and fear and can inhibit uterine blood flow and placental perfusion. Relaxation techniques can help to reduce anxiety and fear, in turn decreasing the secretion of catecholamines and ultimately improving the woman's ability to cope with labor.

A client in labor is agitated and nervous about the birth of her child. The nurse explains to the client that fear and anxiety cause the release of certain compounds which can prolong labor. Which compounds is the nurse referring to in the explanation?

catecholamines Fear and anxiety cause the release of catecholamines, such as norepinephrine and epinephrine, which stimulate the adrenergic receptors of the myometrium. This in turn interferes with effective uterine contractions and results in prolonged labor. Estrogen promotes the release of prostaglandins and oxytocin. Relaxin is a hormone that is involved in producing backache by acting on the pelvic joints. Prostaglandins, oxytocin, and relaxin are not produced due to fear or anxiety in clients during labor.

A nurse is providing care to a pregnant woman in labor. The woman is in the first stage of labor. When describing this stage to the client, which event would the nurse identify as the major change occurring during this stage?

cervical dilation The primary change occurring during the first stage of labor is progressive cervical dilation. Contractions occur during the first and second stages of labor. Fetal movement through the birth canal is the major change during the second stage of labor. Placental separation occurs during the third stage of labor.

There are four essential components of labor. The first is the passageway. It is composed of the bony pelvis and soft tissues. What is one component of the passageway?

cervix The cervix and vagina are soft tissues that form the part of the passageway known as the birth canal.

A nurse is caring for a pregnant client in labor in a health care facility. The nurse knows that which sign marks the termination of the first stage of labor in the client?

dilation of cervix diameter to 10 cm The first stage of labor terminates with the dilation of the cervix diameter to 10 cm. Diffused abdominal cramping and rupturing of the fetal membrane occurs during the first stage of labor. Regular contractions occur at the beginning of the latent phase of the first stage; they do not mark the end of the first stage of labor.

When teaching a group of nursing students about the stages of labor, the nurse explains that softening, thinning, and shortening of the cervical canal occur during the first stage of labor. Which term is the nurse referring to in the explanation?

effacement The nurse is explaining about effacement, which involves softening, thinning, and shortening of the cervical canal. Dilatation refers to widening of the cervical os from a few millimeters in size to approximately 10 cm wide. Crowning refers to a point in the maternal vagina from where the fetal head cannot recede back after the contractions have passed. Molding is a process in which there is overriding and movement of the bones of the cranial vault, so as to adapt to the maternal pelvis.

The initial descent of the fetus into the pelvis to zero station is which one of the cardinal movements of labor?

engagement The movement of the fetus into the pelvis from the upper uterus is engagement. This is the first cardinal movement of the fetus in preparation for the spontaneous vaginal delivery. Flexion occurs as the fetus encounters resistance from the soft tissues and muscles of the pelvic floor. Extension is the state in which the fetal head is well flexed with the chin on the chest as the fetus travels through the birth canal. Expulsion occurs after emergence of the anterior and posterior shoulders.

During a prenatal visit a pregnant client asks the nurse how to tell whether the contractions she is having are true contractions or Braxton Hicks contractions. Which description should the nurse mention as characteristic of true contractions?

felt first in lower back and sweep around to the abdomen in a wave begin irregularly but become regular and predictable increase in duration, frequency, and intensity True contractions begin irregularly but become regular and predictable; are felt first in the lower back and sweep around to the abdomen in a wave; continue no matter what the woman's level of activity; increase in duration, frequency, and intensity; and achieve cervical dilatation. False (Braxton Hicks) contractions begin and remain irregular; are felt first abdominally and remain confined to the abdomen and groin; often disappear with ambulation or sleep; do not increase in duration, frequency, or intensity; and do not achieve cervical dilatation.

A nurse performs an initial assessment of a laboring woman and reports the following findings to the primary care provider: fetal heart rate is 152 bpm, cervix is 100% effaced and 5 cm dilated, membranes are intact, and presenting part is well applied to the cervix and at -1 station. The nurse recognizes that the client is in which stage of labor?

first, active Because the cervix is dilating (5 cm) and has fully effaced (100%), the woman appears to be in active labor, which is characterized by cervical dilation of 4 to 7 cm. Regular uterine contractions are effective in facilitating fetal descent through the pelvis because the presenting part is well applied on the cervix and at -1 station. Second stage of labor begins when the cervix is 10 cm dilated. The first latent phase is characterized by the onset of regular contractions and cervical dilation of 0 to 4 cm. Third stage of labor is from birth of the infant to completed delivery of the placenta.

A nurse is teaching a group of nursing students about the mechanism of labor when the fetus is in a cephalic presentation. Given in random order are a series of events that take place in a cascade to end with the birth of the baby. Arrange the series of events in the most likely sequence they occur. All options must be used.

flexion internal rotation extension restitution external rotation The sequence of normal mechanism of labor involves flexion, internal rotation, extension, restitution, and external rotation. Following descent, the baby's head encounters resistance and flexes so that the chin touches the chest. During internal rotation, the occiput is rotated 45° anteriorly so as to lie beneath the symphysis pubis. The baby's neck is twisted in internal rotation. Following internal rotation, the delivery of the head is by extension. Once the head is born by extension, there is external rotation, in which it turns 45° more so that the shoulders lie anterior posteriorly.

A new OB/GYN care provider has just finished evaluating her one hundredth client. In reviewing the documentation from all clients thus far, which types of pelvis would the nurse assume the care provider has seen the most and the least?

gynecoid and platypelloid, respectively The gynecoid is the typical female pelvis shape; platypelloid pelvis is the least common type of pelvis in women. Women with anthropoid pelvic shapes are able to give birth normally one third of the time and are somewhat rare. An android pelvis is similar to a male pelvis and is seen in 16% of nonwhite women.

The nurse is teaching a prenatal class the signs and symptoms of true labor. What is the appropriate response by the class that shows an understanding of true labor contractions?

increase even if I relax and take a shower True labor contractions do not stop; they continue and strengthen, as well as increase in frequency. If the contractions subside while taking a shower or relaxing, then they are not labor contractions. The discomfort over the top of the uterus is normal for full term pregnancy.

A nurse is caring for a pregnant client who is in labor. Which maternal physiologic responses should the nurse monitor for in the client as the client progresses through birth? Select all that apply.

increase in blood pressure increase in respiratory rate increase in heart rate

A nurse is caring for a pregnant client with rhythmic uterine contractions. Which feature should the nurse identify as associated with true labor?

increase in frequency of the contractions The nurse should identify that there is an increase in the duration of the contractions associated with true labor. In true labor, the duration, frequency, and intensity of uterine contractions increase. Position change does not reduce the uterine contractions. In false labor, the uterine contractions often disappear with ambulation and sleep. Also, there is no increase in frequency, duration, or intensity of the contractions, and the cervix fails to dilate any further.

A nurse is caring for a pregnant client who is in labor. Which maternal physiologic responses should the nurse monitor for in the client as the client progresses through birth? Select all that apply.

increase in heart rate increase in blood pressure increase in respiratory rate When caring for a client in labor, the nurse should monitor for an increase in the heart rate by 10 to 20 bpm, an increase in blood pressure by as much as 35 mm Hg, and an increase in respiratory rate. During labor, the nurse should monitor for a slight elevation in body temperature as a result of an increase in muscle activity. The nurse should also monitor for decreased gastric emptying and gastric pH, which increases the risk of vomiting with aspiration.

The nurse is reviewing the laboratory test results of a client in labor. Which finding would the nurse consider normal?

increased white blood cell count The nurse should identify increased white blood cell count as the hematological change occurring in a client during labor. The increase in the white blood cell count can be attributed to physical and emotional stress during labor. During labor there could be a decrease, and not increase, in the blood coagulation time. There is an increased, and not a decreased, plasma fibrinogen level during labor. Blood glucose levels are decreased during labor.

A woman is told she has an anthropoid pelvis. This means her pelvis:

is narrow transversely. A gynecoid pelvis is the best shape for birth. An anthropoid pelvis is usually narrow. A "male" pelvis is termed an "android pelvis."

The nurse is working with a client in labor. She is happy and cheerful and states she is "ready to see her baby." What stage or phase of labor would she anticipate the client to be in right now?

latent phase The woman in labor undergoes numerous psychological adaptations during labor. During the latent phase, she is often talkative and happy, and yet anxious. During transition, the client may show fear and anger. During stage two she may remain positive, but the work of labor is very intense.

Place the following stages of labor in order from what occurs first to last. All options must be used.

latent stage active stage transition stage second stage third stage The latent stage is the beginning of labor from approximately 0 cm dilated to 3 to 4 cm dilated. The active stage is from when the cervix is 4 cm dilated to 8 cm dilated. Active labor begins to become more uncomfortable for the client, and the contractions are usually stronger, longer, and closer together. Transition is approximately 8 to 10 cm. The second stage of labor is from when the client is 10 cm dilated to birth of the baby. The third stage of labor is from the birth of the baby to the delivery of the placenta.

The nurse assesses a client in labor and finds that the fetal long axis is longitudinal to the maternal long axis. How should the nurse document this finding?

lie The nurse is assessing fetal lie, the relationship of the fetal long axis to the maternal long axis. When the fetal long axis is longitudinal to the maternal long axis, the lie is said to longitudinal. Presentation is the portion of the fetus that overlies the maternal pelvic inlet. Attitude is the relationship of the different fetal parts to one another. Position is the relationship of the fetal denominator to the different sides of the maternal pelvis.

After teaching a pregnant client who is in her last weeks of pregnancy about the signs and symptoms of approaching labor, which signs or symptoms if identified by the client would indicate effective teaching? Select all that apply.

lightening bloody show backache The signs of approaching labor include lightening, bloody show, and backache. Lightening is the falling forward of the pregnant uterus due to settlement of the fetal head into the maternal pelvis. Backache associated with pelvic cramping pain, which is regular and increases in the intensity, is suggestive of impending labor. Bloody show is the expulsion of the cervical mucus plug tinged with blood, and occurs due to cervical effacement and dilatation. Weight loss and diarrhea are other signs of impending labor. Weight gain and constipation are not signs of impending labor.

The skull is the most important factor in relation to the labor and birth process. The fetal skull must be small enough to travel through the bony pelvis. What feature of the fetal skull helps to make this passage possible?

molding The cartilage between the bones allows the bones to overlap during labor, a process called molding that elongates the fetal skull thereby reducing the diameter of the head.

A 37-year-old woman in the final weeks of her first pregnancy visits the health care provider's office for a scheduled check-up. What might a nurse note as a sign of labor in speaking with the woman prior to the examination?

nesting Nesting is the activity or burst of energy women often experience prior to the onset of labor. The client could express this in her words or by what her activities had been at home. Dilation, effacement, and cervical ripening are all observable by the provider on exam.

Assessment reveals that the fetus of a client in labor is in the vertex presentation. The nurse determines that which part is presenting?

occiput With a vertex presentation, a type of cephalic presentation, the fetal presenting part is the occiput. The shoulders are the presenting part when the fetus is in a shoulder presentation. The brow or sinciput is the presenting part when a fetus is in a brow presentation. The buttocks are the presenting part when a fetus is in a breech presentation.

A client is in the first stage of labor and asks the nurse what type of pain she should expect at this stage. What is the nurse's most appropriate response?

pain from the dilation or stretching of the cervix In the first stage of labor, the primary source of pain is the dilation of the cervix. Hypoxia of the contracting uterine muscles, distension of the vagina and perineum, and pressure on the lower back, buttocks, and thighs may occur in the first stage but are more significantly associated with the second stage of labor.

The five "Ps" of labor are:

passageway, passenger, position, powers, psych

When educating a group of nursing students about the different types of pelvis, the nurse describes one type as being flat, having a wider transverse diameter than anterior-posterior diameter, with ischial spines that are wide apart, and a short sacrum. The students are correct when they identify this description with which type?

platypelloid Platypelloid pelvis is a flat pelvis with a wider transverse diameter than anterior-posterior diameter, ischial spines are wide apart, and the sacrum is short. In a gynecoid pelvis, the inlet is oval, the pubic arch is wide, it has dull ischial spines, and the sacrum has no anterior or posterior inclinations. In an android pelvis, the inlet is heart shaped, the ischial spines are prominent, and the sacrum is straight. In an anthropoid pelvis, the anterior-posterior diameter is longer than the transverse diameter, ischial spine is somewhat prominent, and the sacrum is inclined posteriorly.

A nurse knows that a doula can be part of a laboring client's health care team. Which intervention would the nurse explain to the client is part of the doula's responsibility?

providing support and explanations during labor and birth A doula provides support, encouragement, comfort measures, and explanations of the process throughout labor and birth. The doula does not replace the partner/father or provide nursing tasks during the process.

A pregnant woman comes to the emergency department because she thinks she is in labor. The nurse determines that the client is in true labor when assessment of contractions reveals which finding?

radiating to the front of the abdomen from the back Contractions that begin in the back and then radiate to the front are typical of true labor. Contractions that slow when a woman walks or changes position suggest false labor, as do irregular contractions. Contractions lasting 30 seconds or less commonly suggest Braxton Hicks contractions and are associated with false labor.

A pregnant client is admitted to a maternity clinic after experiencing contractions. The assigned nurse observes that the client experiences pauses between contractions. The nurse knows that which event marks the importance of the pauses between contractions during labor?

restoration of blood flow to uterus and placenta The pauses between contractions during labor are important because they allow the restoration of blood flow to the uterus and the placenta. Shortening of the upper uterine segment, reduction in length of the cervical canal, and effacement and dilation of the cervix are other processes that occur during uterine contractions.

A client has just given birth to a healthy baby boy, but the placenta has not yet delivered. What stage of labor does this scenario represent?

third Stage three begins with the birth of the baby and ends with delivery of the placenta.

A multigravid client has been in labor for several hours and is becoming anxious and distressed with the intensity of her frequent contractions. The nurse observes moderate bloody show and performs a vaginal examination to assess the progress of labor. The cervix is 9 cm dilated. The nurse knows that the client is in which phase of labor?

transition phase The woman is likely in transitional labor (first stage, transition phase) as evidenced by her increasing anxiety and distress, intense frequent contractions, and cervical dilation of 9 cm. The amount of bloody show indicates remarkable cervical changes. Cervical dilation in the transition phase is 8 to 10 cm. The latent and early phase is the same phase of labor in the first stage and characterized by positive coping, mild contractions, and cervical dilation of 1 to 4 cm. The active phase is characterized by increased anxiety but cervical dilation of 4 to 7 cm.

During the second stage of labor, a woman is generally:

turning inward to concentrate on body sensations. Second-stage contractions are so unusual that most women are unable to think of things other than what is happening inside their body.
