Unit 3 Preterm Infants/Labor

The nurse is planning to teach the parents of a preterm infant about the infant's nutritional needs. Which nutrients are required in greater quantities in a preterm infant than a full-term one? 1 Proteins 2 Carbohydrates 3 Vitamins A, D, E, and K 4 Calcium and phosphorus

1 Proteins Proteins are needed for tissue building; therefore the preterm infant's need for protein is greater than the full-term infant's. Carbohydrates are not needed in greater quantities by the preterm infant than by the full-term infant. Vitamins A, D, E, and K are fat-soluble vitamins; all of these vitamins are needed, but the B vitamins, found in proteins, are most important for the preterm infant. Although minerals are needed for electrolyte balance, they are not the priority nutrient for a preterm newborn.

Which statement by a new mother observing her preterm infant in the neonatal intensive care nursery indicates that she has not yet begun the bonding process? 1 "It's such a tiny baby." 2 "Do you think he'll make it?" 3 "Why does he need to be in an incubator?" 4 "My baby looks so much like my husband."

1 "It's such a tiny baby." By failing to acknowledge the infant as a person, the client indicates that she has not released her fantasy baby and accepted the real baby. Acknowledging the infant by using the word "he" denotes a relationship. Saying that the baby looks like her husband indicates that the mother has incorporated the infant into the family.

Which activity would help prepare a client to care for her preterm infant who is in the neonatal intensive care unit? 1 She will be encouraged to participate in the infant's care as much as possible. 2 She may watch the care to familiarize herself with the specific routines. 3 She should find someone with preterm care training to help at home for the first week. 4 She will be able to care for the infant in a special nursery for a few days before discharge.

1 She will be encouraged to participate in the infant's care as much as possible. By participating in her infant's care, the mother will gain confidence in her own ability to meet her infant's needs. Watching the provision of care by others may only increase the client's sense of inadequacy. There is no need for a specialist to care for the infant after discharge. The mother should be involved with infant care as early as possible, not just a few days before discharge.

Which is prevented by providing warm, humidified oxygen to a preterm infant? 1 Apnea 2 Cold stress 3 Respiratory distress 4 Bronchopulmonary dysplasia

2 Cold stress By warming and humidifying oxygen, the nurse will prevent cold stress and drying of the mucosa. Apnea and bronchopulmonary dysplasia are not associated with the administration of oxygen that is not warmed or humidified. Respiratory distress can develop in a preterm infant as a result of the cold stress.

The parent of a preterm infant asks the nurse in the neonatal intensive care unit why the baby is in a bed with a radiant warmer. How would the nurse explain the increased risk for hypothermia in preterm infants? 1 Have a smaller body surface area than full-term newborns 2 Lack the subcutaneous fat that usually provides insulation 3 Perspire excessively, causing a constant loss of body heat 4 Have a limited ability to produce antibodies against infections

2 Lack the subcutaneous fat that usually provides insulation Much of a full-term infant's birth weight (almost a third) is gained during the last month of gestation, and most of this final spurt is related to an increase in subcutaneous fat, which serves as insulation; the preterm infant did not have enough time to grow in the uterus and has little of this insulating layer. The preterm infant has a relatively larger surface area per body weight than does a term infant. Preterm infants do not shiver or perspire. Depressed antibody production is unrelated to maintenance of body temperature.

An infant was born 2 hours ago at 37 weeks of gestation and weighing 4.1 kg. The infant appears chubby with a flushed complexion and is very tremulous. The tremors are most likely the result of: a. Birth injury. b. Hypocalcemia. c. Hypoglycemia. d. Seizures.

ANS: C Hypoglycemia is common in the macrosomic infant. Signs of hypoglycemia include jitteriness, apnea, tachypnea, and cyanosis.

The primary health care provider instructs the nurse to apply an emollient to an infant. During assessment, the nurse finds that the neonate is a preterm infant and has a body weight of 900 g. Which is the appropriate nursing intervention in this situation? 1 Administer intravenous fluids before applying emollient. 2 Monitor for coagulase-negative staphylococcal infection. 3 Avoid applying emollient to dry, flaking, and fissured areas on the skin. 4 Hold applying emollient and recheck with the primary health care provider

2 Monitor for coagulase-negative staphylococcal infection. Emollients can cause coagulase-negative staphylococcal infection in a preterm infant who weighs 900 g or less. Intravenous fluids do not increase the effectiveness of the emollients, so there is no need to administer intravenous fluids before applying the emollient. Emollients effectively reduce dry, flaking, and fissured areas on the infant's skin. Emollients are not contraindicated in preterm infants, so there is no need to hold application or recheck with the primary health care provider.

Prepidil (prostaglandin gel) has been ordered for a pregnant woman at 43 weeks of gestation. The nurse recognizes that this medication will be administered to: a. Enhance uteroplacental perfusion in an aging placenta. b. Increase amniotic fluid volume. c. Ripen the cervix in preparation for labor induction. d. Stimulate the amniotic membranes to rupture.

ANS: C It is accurate to state that Prepidil will be administered to ripen the cervix in preparation for labor induction. It is not administered to enhance uteroplacental perfusion

A client is being shown her preterm infant in the neonatal intensive care unit (NICU) for the first time. The client immediately starts to cry and refuses to touch her baby. Which situation would this behavior represent? 1 A typical detachment behavior 2 An incomplete bonding behavior 3 An expected reaction to the situation 4 A negative reaction to the NICU environment

3 An expected reaction to the situation Crying in this situation is a typical response. It is not unusual to be frightened about touching a small preterm infant, and the nurse would provide support while encouraging the mother to do so. Bonding does not involve a detachment behavior phase; the behavior indicates apprehension in a difficult situation. An incomplete bonding behavior is not incomplete bonding but an expression of fear in a difficult situation. The negative reaction to the NICU environment is more complex than mere fear of the NICU.

Which criterion would the nurse use when assessing the gestational age of a preterm infant? 1 Reflex stability 2 Simian creases 3 Breast bud size 4 Fingernail length

3 Breast bud size The size of the breast buds is an indication of gestational age. Small, underdeveloped nipples reflect prematurity. Reflex stability is not a reliable indicator of gestational age; also, reflexes may be impaired in full-term infants. The simian crease is a single palm crease that is a clinical manifestation of Down syndrome, not of prematurity. Although the nails may be longer in a postterm infant, nail length is not a reliable indicator in a preterm infant.

Before administering a nasogastric feeding to a preterm infant, the nurse aspirates a small amount of residual fluid from the stomach. Which action would the nurse take next? 1 Return the aspirate and withhold the feeding. 2 Discard the aspirate and administer the full feeding. 3 Return the aspirate and administer the full feeding. 4 Discard the aspirate and add an equal amount of normal saline solution to the feeding

3 Return the aspirate and administer the full feeding. The aspirate should be returned to ensure that the gastric enzymes and acid-base balance are maintained. Recent evidence indicates that aspirates should not be subtracted from the feeding volume, as this reduces energy intake. Withholding the feeding will compromise the infant's fluid and electrolyte balance, as will discarding the aspirate from the full feeding. Discarding the aspirate and adding an equal amount of normal saline solution to the feeding will compromise the infant's fluid and electrolyte balance.

The nurse is teaching a student about adhesives to be used for preterm infants. Which statement by the student indicates effective learning? 1 "I should remove the adhesive with solvents or bonding agents." 2 "I should remove the adhesive within 24 hours after application." 3 "I should avoid semipermeable dressings to secure intravenous lines." 4 "I should secure pulse oximeter probes with elasticized dressing material."

4 "I should secure pulse oximeter probes with elasticized dressing material." Elasticized dressing material can effectively secure pulse oximeter probes or electrodes with minimal skin irritation in preterm infants. Adhesive removers, solvents, or bonding agents may result in skin damage in a preterm neonate. The adhesives are removed using water, mineral oil, or petrolatum. The adhesive should not be removed for at least 24 hours after application. Semipermeable dressings can be used to secure intravenous lines and silicone catheters in a preterm neonate.

The nurse is caring for preterm infants with respiratory distress in the neonatal intensive care unit. Which is the priority nursing action? 1 Limiting caloric intake to decrease metabolic rate 2 Maintaining the prone position to prevent aspiration 3 Limiting oxygen concentration to prevent eye damage 4 Maintaining a high-humidity environment to promote gas exchange

4 Maintaining a high-humidity environment to promote gas exchange The moisture provided by the humidity liquefies the tenacious secretions, making gas exchange possible. Caloric intake is increased; the amount, number, and type of feedings are related to the metabolic rate. Infants should be placed in a side-lying rather than a prone position; the prone position is associated with apnea and sudden infant death syndrome. Limiting oxygen concentration to prevent eye damage is not a routine action; the concentration of oxygen depends on the oxygen concentration of the neonate's blood gases.

Which complication of prematurity would the nurse monitor for in a 6-day-old preterm infant in the neonatal intensive care unit? 1 Meconium ileus 2 Duodenal atresia 3 Imperforate anus 4 Necrotizing enterocolitis

4 Necrotizing enterocolitis (NEC) is an inflammatory disease of the gastrointestinal mucosa related to several factors (e.g., prematurity, hypoxemia, high-solute feedings); it involves shunting of blood from the gastrointestinal tract, decreased secretion of mucus, greater permeability of the mucosa, and increased growth of gas-forming bacteria, eventually resulting in obstruction. NEC usually manifests 4 to 10 days after birth. Meconium ileus occurs within the first 24 hours when the newborn cannot pass any stool. It is not related to the development of NEC; it is a complication of cystic fibrosis. Duodenal atresia is a congenital defect that occurs early in gestation and is present at birth. Imperforate anus is an anorectal malformation that results in the absence of an external anal opening; it is present at birth.

The nurse is caring for a preterm infant who is receiving oxygen therapy. Which would the nurse do to prevent retinopathy of prematurity (ROP)? 1 Cover the neonate's eyes with a shield. 2 Place the neonate in an elevated side-lying position. 3 Assess the neonate every hour with a pulse oximeter. 4 Support the neonate's oxygen saturation while providing minimal FiO 2

4 Support the neonate's oxygen saturation while providing minimal FiO 2 ROP is a complex disease of the preterm infant; hyperoxemia is one of the numerous causes implicated. Oxygen therapy is maintained at the lowest level necessary to support respiratory status. If the oxygen concentration needs to be increased to maintain life, ROP may not be preventable. Using a shield over the neonate's eyes will not prevent the development of ROP, nor does positioning or assessment of the neonate every hour with a pulse oximeter alone. If the pulse oximetry results are within an acceptable range, the oxygen concentration may be reduced.

A client starts to cry and will not touch her infant when she enters the neonatal intensive care unit (NICU) and sees her preterm infant for the first time. Which interpretation of this behavior would most likely be correct? 1 Incomplete attachment 2 Reaction to the environment 3 Expected detachment behavior 4 Typical reaction to the situation

4 Typical reaction to the situation Crying in this situation is a typical response; it is expected that the mother will be frightened about touching her small preterm infant. The nurse would provide support and encourage the mother to seek contact with the infant. This is not incomplete attachment but fear in a difficult situation. The reaction to the infant is more complex than merely fear of the NICU. This behavior indicates apprehension in a difficult situation; it is not a detachment behavior.

A woman in preterm labor at 30 weeks of gestation receives two 12-mg doses of betamethasone intramuscularly. The purpose of this pharmacologic treatment is to: a. Stimulate fetal surfactant production. b. Reduce maternal and fetal tachycardia associated with ritodrine administration. c. Suppress uterine contractions. d. Maintain adequate maternal respiratory effort and ventilation during magnesium sulfate therapy.

ANS: A Antenatal glucocorticoids given as intramuscular injections to the mother accelerate fetal lung maturity. Inderal would be given to reduce the effects of ritodrine administration. Betamethasone has no effect on uterine contractions. Calcium gluconate would be given to reverse the respiratory depressive effects of magnesium sulfate therapy.

Which patient status is an acceptable indication for serial oxytocin induction of labor? a. Past 42 weeks gestation b. Multiple fetuses c. Polyhydramnios d. History of long labors

ANS: A Continuing a pregnancy past the normal gestational period is likely to be detrimental to fetal health. Multiple fetuses overdistend the uterus and make induction of labor high risk. Polyhydramnios overdistends the uterus, again making induction of labor high risk. History of rapid labors is a reason for induction of labor because of the possibility that the baby would otherwise be born in uncontrolled circumstances.

9. An infant at 26 weeks of gestation arrives intubated from the delivery room. The nurse weighs the infant, places him under the radiant warmer, and attaches him to the ventilator at the prescribed settings. A pulse oximeter and cardiorespiratory monitor are placed. The pulse oximeter is recording oxygen saturations of 80%. The prescribed saturations are 92%. The nurses most appropriate action would be to: a. Listen to breath sounds and ensure the patency of the endotracheal tube, increase oxygen, and notify a physician. b. Continue to observe and make no changes until the saturations are 75%. c. Continue with the admission process to ensure that a thorough assessment is completed. d. Notify the parents that their infant is not doing well.

ANS: A Listening to breath sounds and ensuring the patency of the endotracheal tube, increasing oxygen, and notifying a physician are appropriate nursing interventions to assist in optimal oxygen saturation of the infant. Oxygenation of the infant is crucial. O2 saturation should be maintained above 92%. Oxygenation status of the infant is crucial. The nurse should delay other tasks to stabilize the infant. Notifying the parents that the infant is not doing well is not an appropriate action. Further assessment and intervention are warranted before determination of fetal status.

A premature infant with respiratory distress syndrome receives artificial surfactant. How would the nurse explain surfactant therapy to the parents? a. Surfactant improves the ability of your babys lungs to exchange oxygen and carbon dioxide. b. The drug keeps your baby from requiring too much sedation. c. Surfactant is used to reduce episodes of periodic apnea. d. Your baby needs this medication to fight a possible respiratory tract infection.

ANS: A Surfactant can be administered as an adjunct to oxygen and ventilation therapy. With administration of artificial surfactant, respiratory compliance is improved until the infant can generate enough surfactant on his or her own. Surfactant has no bearing on the sedation needs of the infant. Surfactant is used to improve respiratory compliance, including the exchange of oxygen and carbon dioxide. The goal of surfactant therapy in an infant with respiratory distress syndrome (RDS) is to stimulate production of surfactant in the type 2 cells of the alveoli. The clinical presentation of RDS and neonatal pneumonia may be similar. The infant may be started on broad-spectrum antibiotics to treat infection.

In evaluating the effectiveness of oxytocin induction, the nurse would expect: a. Contractions lasting 40 to 90 seconds, 2 to 3 minutes apart. b. The intensity of contractions to be at least 110 to 130 mm Hg. c. Labor to progress at least 2 cm/hr dilation. d. At least 30 mU/min of oxytocin will be needed to achieve cervical dilation.

ANS: A The goal of induction of labor would be to produce contractions that occur every 2 to 3 minutes and last 60 to 90 seconds. The intensity of the contractions should be 40 to 90 mm Hg by intrauterine pressure catheter. Cervical dilation of 1 cm/hr in the active phase of labor would be the goal in an oxytocin induction. The dose is increased by 1 to 2 mU/min at intervals of 30 to 60 minutes

Immediately after the forceps-assisted birth of an infant, the nurse should: a. Assess the infant for signs of trauma. b. Give the infant prophylactic antibiotics. c. Apply a cold pack to the infants scalp. d. Measure the circumference of the infants head.

ANS: A The infant should be assessed for bruising or abrasions at the site of application, facial palsy, and subdural hematoma. Prophylactic antibiotics are not necessary with a forceps delivery. A cold pack would put the infant at risk for cold stress and is contraindicated. Measuring the circumference of the head is part of the initial nursing assessment.

In the assessment of a preterm infant, the nurse notices continued respiratory distress even though oxygen and ventilation have been provided. The nurse should suspect: a. Hypovolemia and/or shock. b. A nonneutral thermal environment. c. Central nervous system injury. d. Pending renal failure.

ANS: A The nurse should suspect hypovolemia and/or shock. Other symptoms could include hypotension, prolonged capillary refill, and tachycardia followed by bradycardia. Intervention is necessary.

A pregnant womans amniotic membranes rupture. Prolapsed umbilical cord is suspected. What intervention would be the top priority? a. Placing the woman in the knee-chest position b. Covering the cord in sterile gauze soaked in saline c. Preparing the woman for a cesarean birth d. Starting oxygen by face mask

ANS: A The woman is assisted into a position (e.g., modified Sims position, Trendelenburg position, or the knee-chest position) in which gravity keeps the pressure of the presenting part off the cord. Although covering the cord in sterile gauze soaked saline, preparing the woman for a cesarean, and starting oxygen by face mark are appropriate nursing interventions in the event of a prolapsed cord, the intervention of top priority would be positioning the mother to relieve cord compression.

The nurse practicing in the perinatal setting should promote kangaroo care regardless of an infants gestational age. This intervention: a. Is adopted from classical British nursing traditions. b. Helps infants with motor and central nervous system impairment. c. Helps infants to interact directly with their parents and enhances their temperature regulation. d. Gets infants ready for breastfeeding.

ANS: C Kangaroo care is skin-to-skin holding in which the infant, dressed only in a diaper, is placed directly on the parents bare chest and then covered. The procedure helps infants interact with their parents and regulates their temperature, among other developmental benefits.

Infants born between 34 0/7 and 36 6/7 weeks of gestation are called late-preterm infants because they have many needs similar to those of preterm infants. Because they are more stable than early-preterm infants, they may receive care that is much like that of a full-term baby. The mother-baby or nursery nurse knows that these babies are at increased risk for (Select all that apply): a. Problems with thermoregulation b. Cardiac distress c. Hyperbilirubinemia d. Sepsis e. Hyperglycemia

ANS: A, C, D Thermoregulation problems, hyperbilirubinemia, and sepsis are all conditions related to immaturity and warrant close observation. After discharge the infant is at risk for rehospitalization related to these problems. AWHONN launched the Near-Term Infant Initiative to study the problem and ways to ensure that these infants receive adequate care. The nurse should ensure that this infant is feeding adequately before discharge and that parents are taught the signs and symptoms of these complications.

Induction of labor is considered an acceptable obstetric procedure if it is in the best interest to deliver the fetus. The charge nurse on the labor and delivery unit is often asked to schedule patients for this procedure and therefore must be cognizant of the specific conditions appropriate for labor induction. These include (Select all that apply): a. Rupture of membranes at or near term. b. Convenience of the woman or her physician. c. Chorioamnionitis (inflammation of the amniotic sac). d. Post-term pregnancy. e. Fetal death.

ANS: A, C, D, E These are all acceptable indications for induction. Other conditions include intrauterine growth retardation (IUGR), maternal-fetal blood incompatibility, hypertension, and placental abruption. Elective inductions for the convenience of the woman or her provider are not recommended; however, they have become commonplace. Factors such as rapid labors and living a long distance from a health care facility may be valid reasons in such a circumstance. Elective delivery should not occur before 39 weeks completed gestation.

While caring for the patient who requires an induction of labor, the nurse should be cognizant that: a. Ripening the cervix usually results in a decreased success rate for induction. b. Labor sometimes can be induced with balloon catheters or laminaria tents. c. Oxytocin is less expensive than prostaglandins and more effective but creates greater health risks. d. Amniotomy can be used to make the cervix more favorable for labor.

ANS: B Balloon catheters or laminaria tents are mechanical means of ripening the cervix. Ripening the cervix, making it softer and thinner, increases the success rate of induced labor. Prostaglandin E1 is less expensive and more effective than oxytocin but carries a greater risk. Amniotomy is the artificial rupture of membranes, which is used to induce labor only when the cervix is already ripe.

Nurses should know some basic definitions concerning preterm birth, preterm labor, and low birth weight. For instance: a. The terms preterm birth and low birth weight can be used interchangeably. b. Preterm labor is defined as cervical changes and uterine contractions occurring between 20 and 37 weeks of pregnancy. c. Low birth weight is anything below 3.7 pounds. d. In the United States early in this century, preterm birth accounted for 18% to 20% of all births.

ANS: B Before 20 weeks, it is not viable (miscarriage); after 37 weeks, it can be considered term. Although these terms are used interchangeably, they have different meanings: preterm birth describes the length of gestation (37 weeks) regardless of weight; low birth weight describes weight only (2500 g or less) at the time of birth, whenever it occurs. Low birth weight is anything less than 2500 g, or about 5.5 pounds. In 2003 the preterm birth rate in the United States was 12.3%, but it is increasing in frequency.

In planning for an expected cesarean birth for a woman who has given birth by cesarean previously and who has a fetus in the transverse presentation, which information would the nurse include? a. Because this is a repeat procedure, you are at the lowest risk for complications. b. Even though this is your second cesarean birth, you may wish to review the preoperative and postoperative procedures. c. Because this is your second cesarean birth, you will recover faster. d. You will not need preoperative teaching because this is your second cesarean birth.

ANS: B Even though this is your second cesarean birth, you may wish to review the preoperative and postoperative procedures is the most appropriate statement. It is not accurate to state that the woman is at the lowest risk for complications. Both maternal and fetal risks are associated with every cesarean section. Because this is your second cesarean birth, you will recover faster is not an accurate statement. Physiologic and psychologic recovery from a cesarean section is multifactorial and individual to each client each time. Preoperative teaching should always be performed, regardless of whether the client has already had this procedure.

In caring for the preterm infant, what complication is thought to be a result of high arterial blood oxygen level? a. Necrotizing enterocolitis (NEC) b. Retinopathy of prematurity (ROP) c. Bronchopulmonary dysplasia (BPD) d. Intraventricular hemorrhage (IVH)

ANS: B ROP is thought to occur as a result of high levels of oxygen in the blood. NEC is caused by the interference of blood supply to the intestinal mucosa. Necrotic lesions occur at that site. BPD is caused by the use of positive pressure ventilation against the immature lung tissue. IVH results from rupture of the fragile blood vessels in the ventricles of the brain. It is most often associated with hypoxic injury, increased blood pressure, and fluctuating cerebral blood flow.

The nurse providing care for a woman with preterm labor who is receiving terbutaline would include which intervention to identify side effects of the drug? a. Assessing deep tendon reflexes (DTRs) b. Assessing for chest discomfort and palpitations c. Assessing for bradycardia d. Assessing for hypoglycemia

ANS: B Terbutaline is a b2 -adrenergic agonist that affects the cardiopulmonary and metabolic systems of the mother. Signs of cardiopulmonary decompensation would include chest pain and palpitations. Assessing DTRs would not address these concerns. b2 -Adrenergic agonist drugs cause tachycardia, not bradycardia. The metabolic effect leads to hyperglycemia, not hypoglycemia.

Surgical, medical, or mechanical methods may be used for labor induction. Which technique is considered a mechanical method of induction? a. Amniotomy b. Intravenous Pitocin c. Transcervical catheter d. Vaginal insertion of prostaglandins

ANS: C Placement of a balloon-tipped Foley catheter into the cervix is a mechanical method of induction. Othermethods to expand and gradually dilate the cervix include hydroscopic dilators such as laminaria tents (made from desiccated seaweed), or Lamicel (contains magnesium sulfate). Amniotomy is a surgical method of augmentation and induction. Intravenous Pitocin and insertion of prostaglandins are medical methods of induction.

A pregnant woman at 29 weeks of gestation has been diagnosed with preterm labor. Her labor is being controlled with tocolytic medications. She asks when she would be able to go home. Which response by the nurse is most accurate? a. After the baby is born. b. When we can stabilize your preterm labor and arrange home health visits. c. Whenever the doctor says that it is okay. d. It depends on what kind of insurance coverage you have.

ANS: B The clients preterm labor is being controlled with tocolytics. Once she is stable, home care may be a viable option for this type of client. Care of a woman with preterm labor is multifactorial; the goal is to prevent delivery. In many cases this may be achieved at home. Care of the preterm client is multidisciplinary and multifactorial. Managed care may dictate earlier hospital discharges or a shift from hospital to home care. Insurance coverage may be one factor in the care of clients, but ultimately client safety remains the most important factor.

A newborn was admitted to the neonatal intensive care unit after being delivered at 29 weeks of gestation to a 28-year-old multiparous, married, Caucasian woman whose pregnancy was uncomplicated until premature rupture of membranes and preterm birth. The newborns parents arrive for their first visit after the birth. The parents walk toward the bedside but remain approximately 5 feet away from the bed. The nurses most appropriate action would be to: a. Wait quietly at the newborns bedside until the parents come closer. b. Go to the parents, introduce himself or herself, and gently encourage the parents to come meet their infant; explain the equipment first, and then focus on the newborn. c. Leave the parents at the bedside while they are visiting so they can have some privacy. d. Tell the parents only about the newborns physical condition, and caution them to avoid touching their baby.

ANS: B The nurse is instrumental in the initial interactions with the infant. The nurse can help the parents see the infant, rather than focus on the equipment. The importance and purpose of the apparatus that surrounds their infant also should be explained to them. Parents often need encouragement and recognition from the nurse to acknowledge the reality of the infants condition. Parents need to see and touch their infant as soon as possible to acknowledge the reality of the birth and the infants appearance and condition. Encouragement from the nurse is instrumental in this process. Telling the parents only about the newborns physical condition and cautioning them to avoid touching their baby is an inappropriate action.

The nurse is caring for a client whose labor is being augmented with oxytocin. He or she recognizes that the oxytocin should be discontinued immediately if there is evidence of: a. Uterine contractions occurring every 8 to 10 minutes. b. A fetal heart rate (FHR) of 180 with absence of variability. c. The clients needing to void. d. Rupture of the clients amniotic membranes.

ANS: B This FHR is nonreassuring. The oxytocin should be discontinued immediately, and the physician should be notified. The oxytocin should be discontinued if uterine hyperstimulation occurs. Uterine contractions that are occurring every 8 to 10 minutes do not qualify as hyperstimulation. The clients needing to void is not an indication to discontinue the oxytocin induction immediately or to call the physician. Unless a change occurs in the FHR pattern that is nonreassuring or the client experiences uterine hyperstimulation, the oxytocin does not need to be discontinued. The physician should be notified that the clients membranes have ruptured.

The exact cause of preterm labor is unknown and believed to be multifactorial. Infection is thought to be a major factor in many preterm labors. Select the type of infection that has not been linked to preterm births. a. Viral b. Periodontal c. Cervical d. Urinary tract

ANS: B, C, D The infections that increase the risk of preterm labor and birth are all bacterial. They include cervical, urinary tract, periodontal, and other bacterial infections. Therefore, it is important for the client to participate in early, continual, and comprehensive prenatal care. Evidence has shown a link between periodontal infections and preterm labor. Researchers recommend regular dental care before and during pregnancy, oral assessment as a routine part of prenatal care, and scrupulous oral hygiene to prevent infection. Cervical infections of a bacterial nature have been linked to preterm labor and birth. The presence of urinary tract infections increases the risk of preterm labor and birth.

Complications and risks associated with cesarean births include (Select all that apply): a. Placental abruption. b. Wound dehiscence. c. Hemorrhage. d. Urinary tract infections. e. Fetal injuries.

ANS: B, C, D, E Placental abruption and placenta previa are both indications for cesarean birth and are not complications thereof. Wound dehiscence, hemorrhage, urinary tract infection, and fetal injuries are all possible complications and risks associated with delivery by cesarean section.

The nurse recognizes that uterine hyperstimulation with oxytocin requires emergency interventions. What clinical cues would alert the nurse that the woman is experiencing uterine hyperstimulation (Select all that apply)? a. Uterine contractions lasting <90 seconds and occurring >2 minutes in frequency b. Uterine contractions lasting >90 seconds and occurring <2 minutes in frequency c. Uterine tone <20 mm Hg d. Uterine tone >20 mm Hg e. Increased uterine activity accompanied by a nonreassuring fetal heart rate (FHR) and pattern

ANS: B, D, E Uterine contractions that occur less than 2 minutes apart and last more than 90 seconds, a uterine tone of over 20 mm Hg, and a nonreassuring FHR and pattern are all indications of uterine hyperstimulation with oxytocin administration. Uterine contractions that occur more than 2 minutes apart and last less than 90 seconds are the expected goal of oxytocin induction. A uterine tone of less than 20 mm Hg is normal.

As related to the eventual discharge of the high risk newborn or transfer to a different facility, nurses and families should be aware that: a. Infants will stay in the neonatal intensive care unit (NICU) until they are ready to go home. b. Once discharged to home, the high risk infant should be treated like any healthy term newborn. c. Parents of high risk infants need special support and detailed contact information. d. If a high risk infant and mother need transfer to a specialized regional center, it is better to wait until after birth and the infant is stabilized.

ANS: C High risk infants can cause profound parental stress and emotional turmoil. Parents need support, special teaching, and quick access to various resources available to help them care for their baby. Parents and their high risk infant should spend a night or two in a predischarge room, where care for the infant is provided away from the NICU. Just because high risk infants are discharged does not mean that they are normal, healthy babies. Follow-up by specialized practitioners is essential. Ideally, the mother and baby are transported with the fetus in utero; this reduces neonatal morbidity and mortality.

For clinical purposes, preterm and post-term infants are defined as: a. Preterm before 34 weeks if appropriate for gestational age (AGA) and before 37 weeks if small for gestational age (SGA). b. Post-term after 40 weeks if large for gestational age (LGA) and beyond 42 weeks if AGA. c. Preterm before 37 weeks, and post-term beyond 42 weeks, no matter the size for gestational age at birth. d. Preterm, SGA before 38 to 40 weeks, and post-term, LGA beyond 40 to 42 weeks.

ANS: C Preterm and post-term are strictly measures of timebefore 37 weeks and beyond 42 weeks, respectivelyregardless of size for gestational age.

In planning for home care of a woman with preterm labor, which concern must the nurse address? a. Nursing assessments will be different from those done in the hospital setting. b. Restricted activity and medications will be necessary to prevent recurrence of preterm labor. c. Prolonged bed rest may cause negative physiologic effects. d. Home health care providers will be necessary.

ANS: C Prolonged bed rest may cause adverse effects such as weight loss, loss of appetite, muscle wasting, weakness, bone demineralization, decreased cardiac output, risk for thrombophlebitis, alteration in bowel functions, sleep disturbance, and prolonged postpartum recovery. Nursing assessments will differ somewhat from those performed in the acute care setting, but this is not the concern that needs to be addressed. Restricted activity and medication may prevent preterm labor, but not in all women. In addition, the plan of care is individualized to meet the needs of each woman. Many women will receive home health nurse visits, but care is individualized for each woman.

An infant is being discharged from the neonatal intensive care unit after 70 days of hospitalization. The infant was born at 30 weeks of gestation with several conditions associated with prematurity, including respiratory distress syndrome, mild bronchopulmonary dysplasia, and retinopathy of prematurity requiring surgical treatment. During discharge teaching the infants mother asks the nurse whether her baby will meet developmental milestones on time, as did her son who was born at term. The nurses most appropriate response is: a. Your baby will develop exactly like your first child did. b. Your baby does not appear to have any problems at the present time. c. Your baby will need to be corrected for prematurity. Your baby is currently 40 weeks of postconceptional age and can be expected to be doing what a 40-week-old infant would be doing. d. Your baby will need to be followed very closely.

ANS: C The age of a preterm newborn is corrected by adding the gestational age and the postnatal age. The infants responses are evaluated accordingly against the norm expected for the corrected age of the infant. Although it is impossible to predict with complete accuracy the growth and development potential of each preterm infant, certain measurable factors predict normal growth and development. The preterm infant experiences catch-up body growth during the first 2 to 3 years of life. The growth and developmental milestones are corrected for gestational age until the child is approximately 2.5 years old. Stating that the baby does not appear to have any problems at the present time is inaccurate. Development will need to be evaluated over time.

As a result of large body surface in relation to weight, the preterm infant is at high risk for heat loss and cold stress. By understanding the four mechanisms of heat transfer (convection, conduction, radiation, and evaporation), the nurse can create an environment for the infant that prevents temperature instability. While evaluating the plan that has been implemented, the nurse knows that the infant is experiencing cold stress when he or she exhibits: a. Decreased respiratory rate. b. Bradycardia followed by an increased heart rate. c. Mottled skin with acrocyanosis. d. Increased physical activity.

ANS: C The infant has minimal to no fat stores. During times of cold stress the skin will become mottled, and acrocyanosis will develop, progressing to cyanosis. Even if the infant is being cared for on a radiant warmer or an an isolette, the nurses role is to observe the infant frequently to prevent heat loss and respond quickly if signs and symptoms occur. The respiratory rate increases followed by periods of apnea. The infant initially tries to conserve heat and burns more calories, after which the metabolic system goes into overdrive. In the preterm infant experiencing heat loss, the heart rate initially increases, followed by periods of bradycardia. In the term infant, the natural response to heat loss is increased physical activity. However, in a term infant experiencing respiratory distress or in a preterm infant, physical activity is decreased.

The least common cause of long, difficult, or abnormal labor (dystocia) is: a. Midplane contracture of the pelvis. b. Compromised bearing-down efforts as a result of pain medication. c. Disproportion of the pelvis. d. Low-lying placenta.

ANS: C The least common cause of dystocia is disproportion of the pelvis.

The nurse providing care to a woman in labor should understand that cesarean birth: a. Is declining in frequency in the twenty-first century in the United States. b. Is more likely to be performed for poor women in public hospitals who do not receive the nurse counseling as do wealthier clients. c. Is performed primarily for the benefit of the fetus. d. Can be either elected or refused by women as their absolute legal right.

ANS: C The most common indications for cesarean birth are danger to the fetus related to labor and birth complications. Cesarean births are increasing in the United States in this century. Wealthier women who have health insurance and who give birth in a private hospital are more likely to experience cesarean birth. A womans right to elect cesarean surgery is in dispute, as is her right to refuse it if in doing so she endangers the fetus. Legal issues are not absolutely clear.

A woman is having her first child. She has been in labor for 15 hours. Two hours ago her vaginal examination revealed the cervix to be dilated to 5 cm and 100% effaced, and the presenting part was at station 0. Five minutes ago her vaginal examination indicated that there had been no change. What abnormal labor pattern is associated with this description? a. Prolonged latent phase b. Protracted active phase c. Arrest of active phase d. Protracted descent

ANS: C With an arrest of the active phase, the progress of labor has stopped. This client has not had any anticipated cervical change, thus indicating an arrest of labor. In the nulliparous woman a prolonged latent phase typically would last more than 20 hours. A protracted active phase, the first or second stage of labor, would be prolonged (slow dilation). With protracted descent, the fetus would fail to descend at an anticipated rate during the deceleration phase and second stage of labor.

A primigravida at 40 weeks of gestation is having uterine contractions every 1.5 to 2 minutes and says that they are very painful. Her cervix is dilated 2 cm and has not changed in 3 hours. The woman is crying and wants an epidural. What is the likely status of this womans labor? a. She is exhibiting hypotonic uterine dysfunction. b. She is experiencing a normal latent stage. c. She is exhibiting hypertonic uterine dysfunction. d. She is experiencing pelvic dystocia.

ANS: C Women who experience hypertonic uterine dysfunction, or primary dysfunctional labor, often are anxious first- time mothers who are having painful and frequent contractions that are ineffective at causing cervical dilation or effacement to progress. With hypotonic uterine dysfunction, the woman initially makes normal progress into the active stage of labor; then the contractions become weak and inefficient or stop altogether. The contraction pattern seen in this woman signifies hypertonic uterine activity. Typically uterine activity in this phase occurs at 4- to 5-minute intervals lasting 30 to 45 seconds. Pelvic dystocia can occur whenever contractures of the pelvic diameters reduce the capacity of the bony pelvis, including the inlet, midpelvis, outlet, or any combination of these planes.

The priority nursing care associated with an oxytocin (Pitocin) infusion is: a. Measuring urinary output. b. Increasing infusion rate every 30 minutes. c. Monitoring uterine response. d. Evaluating cervical dilation.

ANS: C Because of the risk of hyperstimulation, which could result in decreased placental perfusion and uterine rupture, the nurses priority intervention is monitoring uterine response. Monitoring urinary output is also important; however, it is not the top priority during the administration of Pitocin. The infusion rate may be increased after proper assessment that it is an appropriate interval to do so. Monitoring labor progression is the standard of care for all labor patients.

As relates to the use of tocolytic therapy to suppress uterine activity, nurses should be aware that: a. The drugs can be given efficaciously up to the designated beginning of term at 37 weeks. b. There are no important maternal (as opposed to fetal) contraindications. c. Its most important function is to afford the opportunity to administer antenatal glucocorticoids. d. If the client develops pulmonary edema while receiving tocolytics, intravenous (IV) fluids should be given.

ANS: C Buying time for antenatal glucocorticoids to accelerate fetal lung development may be the best reason to use tocolytics. Once the pregnancy has reached 34 weeks, the risks of tocolytic therapy outweigh the benefits. There are important maternal contraindications to tocolytic therapy. Tocolytic-induced edema can be caused by IV fluids.

Which assessment is least likely to be associated with a breech presentation? a. Meconium-stained amniotic fluid b. Fetal heart tones heard at or above the maternal umbilicus c. Preterm labor and birth d. Post-term gestation

ANS: D Post-term gestation is not likely to be seen with a breech presentation. The presence of meconium in a breech presentation may result from pressure on the fetal wall as it traverses the birth canal. Fetal heart tones heard at the level of the umbilical level of the mother are a typical finding in a breech presentation because the fetal back would be located in the upper abdominal area. Breech presentations often occur in preterm births.

A woman at 26 weeks of gestation is being assessed to determine whether she is experiencing preterm labor. What finding indicates that preterm labor is occurring? a. Estriol is not found in maternal saliva. b. Irregular, mild uterine contractions are occurring every 12 to 15 minutes. c. Fetal fibronectin is present in vaginal secretions. d. The cervix is effacing and dilated to 2 cm.

ANS: D Cervical changes such as shortened endocervical length, effacement, and dilation are predictors of imminent preterm labor. Changes in the cervix accompanied by regular contractions indicate labor at any gestation. Estriol is a form of estrogen produced by the fetus that is present in plasma at 9 weeks of gestation. Levels of salivary estriol have been shown to increase before preterm birth. Irregular, mild contractions that do not cause cervical change are not considered a threat. The presence of fetal fibronectin in vaginal secretions between 24 and 36 weeks of gestation could predict preterm labor, but it has only a 20% to 40% positive predictive value. Of more importance are other physiologic clues of preterm labor such as cervical changes.

With regard to the care management of preterm labor, nurses should be aware that: a. Because all women must be considered at risk for preterm labor and prediction is so hit-and-miss, teaching pregnant women the symptoms probably causes more harm through false alarms. b. Braxton Hicks contractions often signal the onset of preterm labor. c. Because preterm labor is likely to be the start of an extended labor, a woman with symptoms can wait several hours before contacting the primary caregiver. d. The diagnosis of preterm labor is based on gestational age, uterine activity, and progressive cervical change.

ANS: D Gestational age of 20 to 37 weeks, uterine contractions, and a cervix that is 80% effaced or dilated 2 cm indicates preterm labor. It is essential that nurses teach women how to detect the early symptoms of preterm labor. Braxton Hicks contractions resemble preterm labor contractions, but they are not true labor. Waiting too long to see a health care provider could result in not administering essential medications. Preterm labor is not necessarily long-term labor.

When assessing the preterm infant the nurse understands that compared with the term infant, the preterm infant has: a. Few blood vessels visible through the skin. b. More subcutaneous fat. c. Well-developed flexor muscles. d. Greater surface area in proportion to weight.

ANS: D Preterm infants have greater surface area in proportion to their weight. More subcutaneous fat and well- developed muscles are indications of a more mature infant.

For a woman at 42 weeks of gestation, which finding would require further assessment by the nurse? a. Fetal heart rate of 116 beats/min b. Cervix dilated 2 cm and 50% effaced c. Score of 8 on the biophysical profile d. One fetal movement noted in 1 hour of assessment by the mother

ANS: D Self-care in a post-term pregnancy should include performing daily fetal kick counts three times per day. The mother should feel four fetal movements per hour. If fewer than four movements have been felt by the mother, she should count for 1 more hour. Fewer than four movements in that hour warrants evaluation. Normal findings in a 42-week gestation include fetal heart rate of 116 beats/min, cervix dilated 20 cm and 50% effaced, and a score of 8 on the biophysical profile.

The priority nursing intervention after an amniotomy should be to: a. Assess the color of the amniotic fluid. b. Change the patients gown. c. Estimate the amount of amniotic fluid. d. Assess the fetal heart rate.

ANS: D The fetal heart rate must be assessed immediately after the rupture of the membranes to determine whether cord prolapse or compression has occurred. Secondary to FHR assessment, amniotic fluid amount, color, odor, and consistency is assessed. Dry clothing is important for patient comfort; however, it is not the top priority.

While completing a newborn assessment, the nurse should be aware that the most common birth injury is: a. To the soft tissues. b. Caused by forceps gripping the head on delivery. c. Fracture of the humerus and femur. d. Fracture of the clavicle.

ANS: D The most common birth injury is fracture of the clavicle (collarbone). It usually heals without treatment,

Because of the premature infants decreased immune functioning, what nursing diagnosis should the nurse include in a plan of care for a premature infant? a. Delayed growth and development b. Ineffective thermoregulation c. Ineffective infant feeding pattern d. Risk for infection

ANS: D The nurse needs to understand that decreased immune functioning increases the risk for infection. Growth and development, thermoregulation, and feeding may be affected, although only indirectly.

A pregnant woman at 37 weeks of gestation has had ruptured membranes for 26 hours. A cesarean section is performed for failure to progress. The fetal heart rate (FHR) before birth is 180 beats/min with limited variability. At birth the newborn has Apgar scores of 6 and 7 at 1 and 5 minutes and is noted to be pale and tachypneic. On the basis of the maternal history, the cause of this newborns distress is most likely to be: a. Hypoglycemia. b. Phrenic nerve injury. c. Respiratory distress syndrome. d. Sepsis.

ANS: D The prolonged rupture of membranes and the tachypnea (before and after birth) both suggest sepsis. An FHR of 180 beats/min is also indicative. This infant is at high risk for sepsis.

In evaluating the effectiveness of magnesium sulfate for the treatment of preterm labor, what finding would alert the nurse to possible side effects? a. Urine output of 160 mL in 4 hours b. Deep tendon reflexes 2+ and no clonus c. Respiratory rate of 16 breaths/min d. Serum magnesium level of 10 mg/dL

ANS: D The therapeutic range for magnesium sulfate management is 5 to 8 mg/dL. A serum magnesium level of 10 mg/dL could lead to signs and symptoms of magnesium toxicity, including oliguria and respiratory distress. Urine output of 160 mL in 4 hours, deep tendon reflexes 2+ with no clonus, and respiratory rate of 16 breaths/min are normal findings.

Premature infants who exhibit 5 to 10 seconds of respiratory pauses followed by 10 to 15 seconds of compensatory rapid respiration are: a. Suffering from sleep or wakeful apnea. b. Experiencing severe swings in blood pressure. c. Trying to maintain a neutral thermal environment. d. Breathing in a respiratory pattern common to premature infants.

ANS: D This pattern is called periodic breathing and is common to premature infants. It may still require nursing intervention of oxygen and/or ventilation. Apnea is a cessation of respirations for 20 seconds or longer. It should not be confused with periodic breathing.
