Ch 28 Maternal Child Nursing Perry 4th edition

A major nursing intervention for an infant born with myelomeningocele is to: a. Protect the sac from injury. b. Prepare the parents for the child's paralysis from the waist down. c. Prepare the parents for closure of the sac at around 2 years of age. d. Assess for cyanosis.

ANS: A A major preoperative nursing intervention for a neonate with a myelomeningocele is protection of the protruding sac from injury to prevent its rupture and the resultant risk of central nervous system infection. The long-term prognosis in an affected infant can be determined to a large extent at birth with the degree of neurologic dysfunction related to the level of the lesion, which determines the nerves involved. A myelomeningocele should be surgically closed within 24 hours. Although the nurse would assess for multiple potential problems in this infant, the major nursing intervention would be to protect the sac from injury.

The abuse of which of the following substances during pregnancy is the leading cause of cognitive impairment in the United States? a. Alcohol c. Marijuana b. Tobacco d. Heroin

ANS: A Alcohol abuse during pregnancy is recognized as one of the leading causes of cognitive impairment in the United States.

Which infant would be more likely to have Rh incompatibility? a. Infant of an Rh-negative mother and a father who is Rh positive and homozygous for the Rh factor b. Infant who is Rh negative and whose mother is Rh negative c. Infant of an Rh-negative mother and a father who is Rh positive and heterozygous for the Rh factor d. Infant who is Rh positive and whose mother is Rh positive

ANS: A If the mother is Rh negative and the father is Rh positive and homozygous for the Rh factor, all the offspring will be Rh positive. Only Rh-positive offspring of an Rh-negative mother are at risk for Rh incompatibility. If the mother is Rh negative and the father is Rh positive and heterozygous for the factor, there is a 50% chance that each infant born of the union will be Rh positive and a 50% chance that each will be born Rh negative.

With regard to injuries to the infant's plexus during labor and birth, nurses should be aware that: a. If the nerves are stretched with no avulsion, they should recover completely in 3 to 6 months. b. Erb palsy is damage to the lower plexus. c. Parents of children with brachial palsy are taught to pick up the child from under the axillae. d. Breastfeeding is not recommended for infants with facial nerve paralysis until the condition resolves.

ANS: A If the nerves are stretched with no avulsion, they should recover completely in 3 to 6 months. However, if the ganglia are disconnected completely from the spinal cord, the damage is permanent. Erb palsy is damage to the upper plexus and is less serious than brachial palsy. Parents of children with brachial palsy are taught to avoid picking up the child under the axillae or by pulling on the arms. Breastfeeding is not contraindicated, but both the mother and infant will need help from the nurse at the start.

A careful review of the literature on the various recreational and illicit drugs reveals that: a. More longer-term studies are needed to assess the lasting effects on infants when mothers have taken or are taking illegal drugs. b. Heroin and methadone cross the placenta; marijuana, cocaine, and phencyclidine (PCP) do not. c. Mothers should get off heroin (detox) any time they can during pregnancy. d. Methadone withdrawal for infants is less severe and shorter than heroin withdrawal.

ANS: A Studies on the effects of marijuana and cocaine use by mothers are somewhat contradictory. More long-range studies are needed. Just about all of these drugs cross the placenta, including marijuana, cocaine, and PCP. Drug withdrawal is accompanied by fetal withdrawal, which can lead to fetal death. Therefore detoxification from heroin is not recommended, particularly later in pregnancy. Methadone withdrawal is more severe and more prolonged than heroin withdrawal.

With regard to congenital anomalies of the cardiovascular and respiratory systems, nurses should be aware that: a. Cardiac disease may be manifested by respiratory signs and symptoms. b. Screening for congenital anomalies of the respiratory system need only be done for infants having respiratory distress. c. Choanal atresia can be corrected by a suction catheter. d. Congenital diaphragmatic hernias are diagnosed and treated after birth.

ANS: A The cardiac and respiratory systems function together. Screening for congenital respiratory system anomalies is necessary even for infants who appear normal at birth. Choanal atresia requires emergency surgery. Congenital diaphragmatic hernias are discovered prenatally on ultrasound.

A pregnant woman presents in labor at term, having had no prenatal care. After birth her infant is noted to be small for gestational age with small eyes and a thin upper lip. The infant also is microcephalic. On the basis of her infant's physical findings, this woman should be questioned about her use of which substance during pregnancy? a. Alcohol c. Heroin b. Cocaine d. Marijuana

ANS: A The description of the infant suggests fetal alcohol syndrome, which is consistent with maternal alcohol consumption during pregnancy. Fetal brain, kidney, and urogenital system malformations have been associated with maternal cocaine ingestions. Heroin use in pregnancy frequently results in intrauterine growth restriction. The infant may have a shrill cry and sleep cycle disturbances and present with poor feeding, tachypnea, vomiting, diarrhea, hypothermia or hyperthermia, and sweating. Studies have found a higher incidence of meconium staining in infants born of mothers who used marijuana during pregnancy.

During a prenatal examination, the woman reports having two cats at home. The nurse informs her that she should not be cleaning the litter box while she is pregnant. When the woman asks why, the nurse's best response would be: a. "Your cats could be carrying toxoplasmosis. This is a zoonotic parasite that can infect you and have severe effects on your unborn child." b. "You and your baby can be exposed to the human immunodeficiency virus (HIV) in your cats' feces." c. "It's just gross. You should make your husband clean the litter boxes." d. "Cat feces are known to carry Escherichia coli, which can cause a severe infection in both you and your baby."

ANS: A Toxoplasmosis is a multisystem disease caused by the protozoal Toxoplasma gondii parasite, commonly found in cats, dogs, pigs, sheep, and cattle. About 30% of women who contract toxoplasmosis during gestation transmit the disease to their offspring. Clinical features ascribed to toxoplasmosis include hydrocephalus or microcephaly, chorioretinitis, seizures, or cerebral calcifications. HIV is not transmitted by cats. Although suggesting that the woman's husband clean the litter boxes may be a valid statement, it is not appropriate, does not answer the client's question, and is not the nurse's best response. E. coli is found in normal human fecal flora. It is not transmitted by cats.

The most important nursing action in preventing neonatal infection is: a. Good handwashing. c. Separate gown technique. b. Isolation of infected infants. d. Standard Precautions.

ANS: A Virtually all controlled clinical trials have demonstrated that effective handwashing is responsible for the prevention of nosocomial infection in nursery units. Measures to be taken include Standard Precautions, careful and thorough cleaning, frequent replacement of used equipment, and disposal of excrement and linens in an appropriate manner. Overcrowding must be avoided in nurseries. However, the most important nursing action for preventing neonatal infection is effective handwashing.

Many common drugs of abuse cause significant physiologic and behavioral problems in infants who are breastfed by mothers currently using (choose all that apply): a. Amphetamine. b. Heroin. c. Nicotine. d. PCP. e. Morphine.

ANS: A, B, C, D Amphetamine, heroin, nicotine, and PCP are contraindicated during breastfeeding because of the reported effects on the infant. Morphine is a medication that often is used to treat neonatal abstinence syndrome.

Cleft lip or palate is a common congenital midline fissure, or opening, in the lip or palate resulting from failure of the primary palate to fuse. Multiple genetic and to a lesser extent environmental factors may lead to the development of a cleft lip or palate. Such factors include (choose all that apply): a. Alcohol consumption. b. Female gender. c. Use of some antiepileptics. d. Maternal cigarette smoking. e. Antibiotic use in pregnancy.

ANS: A, C, D Factors that are associated with the potential development of cleft lip or palate are maternal infections, radiation exposure, corticosteroids, anticonvulsants, male gender, Native American or Asian descent, and smoking during pregnancy. Cleft lip is more common in male infants. Antibiotic use in pregnancy is not associated with the development of cleft lip or palate

An infant diagnosed with erythroblastosis fetalis would characteristically exhibit: a. Edema. c. Enlargement of the heart. b. Immature red blood cells. d. Ascites.

ANS: B Erythroblastosis fetalis occurs when the fetus compensates for the anemia associated with Rh incompatibility by producing large numbers of immature erythrocytes to replace those hemolyzed. Edema would occur with hydrops fetalis, a more severe form of erythroblastosis fetalis. The fetus with hydrops fetalis may exhibit effusions into the peritoneal, pericardial, and pleural spaces. The infant with hydrops fetalis displays signs of ascites.

With regard to the classification of neonatal bacterial infection, nurses should be aware that: a. Congenital infection progresses slower than nosocomial infection. b. Nosocomial infection can be prevented by effective handwashing; early-onset infections cannot. c. Infections occur with about the same frequency in boy and girl infants, although female mortality is higher. d. The clinical sign of a rapid, high fever makes infection easier to diagnose.

ANS: B Handwashing is an effective preventive measure for late-onset (nosocomial) infections because these infections come from the environment around the infant. Early-onset, or congenital, infections are caused by the normal flora at the maternal vaginal tract and progress more rapidly than nosocomial (late-onset) infections. Infection occurs about twice as often in boys and results in higher mortality. Clinical signs of neonatal infection are nonspecific and similar to noninfectious problems, making diagnosis difficult.

The most common cause of pathologic hyperbilirubinemia is: a. Hepatic disease. c. Postmaturity. b. Hemolytic disorders in the newborn. d. Congenital heart defect.

ANS: B Hemolytic disorders in the newborn are the most common cause of pathologic jaundice. Hepatic damage may be a cause of pathologic hyperbilirubinemia, but it is not the most common cause. Prematurity would be a potential cause of pathologic hyperbilirubinemia in neonates, but it is not the most common cause. Congenital heart defect is not a common cause of pathologic hyperbilirubinemia in neonates.

With regard to the understanding and treatment of infants born to mothers who are substance abusers, nurses should be aware that: a. Infants born to addicted mothers are also addicted. b. Mothers who abuse one substance likely will use or abuse another, compounding the infant's difficulties. c. The NICU Network Neurobehavioral Scale (NNNS) is designed to assess the damage the mother has done to herself. d. No laboratory procedures are available that can identify the intrauterine drug exposure of the infant.

ANS: B Multiple substance use (even just alcohol and tobacco) makes it difficult to assess the problems of the exposed infant, particularly with regard to withdrawal manifestations. Infants of substance-abusing mothers may have some of the physiologic signs but are not addicted in the behavioral sense. "Drug-exposed newborn" is a more accurate description than "addict." The NNNS is designed to assess the neurologic, behavioral, and stress/abstinence function of the neonate. Newborn urine, hair, or meconium sampling may be used to identify an infant's intrauterine drug exposure.

With regard to skeletal injuries sustained by a neonate during labor or birth, nurses should be aware that: a. A newborn's skull is still forming and fractures fairly easily. b. Unless a blood vessel is involved, linear skull fractures heal without special treatment. c. Clavicle fractures often need to be set with an inserted pin for stability. d. Other than the skull, the most common skeletal injuries are to leg bones.

ANS: B About 70% of neonatal skull fractures are linear. Because the newborn skull is flexible, considerable force is required to fracture it. Clavicle fractures need no special treatment. The clavicle is the bone most often fractured during birth.

Providing care for the neonate born to a mother who abuses substances can present a challenge for the health care team. Nursing care for this infant requires a multisystem approach. The first step in the provision of this care is: a. Pharmacologic treatment. b. Reduction of environmental stimuli. c. Neonatal abstinence syndrome scoring. d. Adequate nutrition and maintenance of fluid and electrolyte balance.

ANS: C Neonatal abstinence syndrome (NAS) is the term used to describe the cohort of symptoms associated with drug withdrawal in the neonate. The Neonatal Abstinence Scoring System evaluates CNS, metabolic, vasomotor, respiratory, and gastrointestinal disturbances. This evaluation tool enables the care team to develop an appropriate plan of care. The infant is scored throughout the length of stay, and the treatment plan is adjusted accordingly. Pharmacologic treatment is based on the severity of withdrawal symptoms. Symptoms are determined by using a standard assessment tool. Medications of choice are morphine, phenobarbital, diazepam, or diluted tincture of opium. Swaddling, holding, and reducing environmental stimuli are essential in providing care to the infant who is experiencing withdrawal. These nursing interventions are appropriate for the infant who displays central nervous system (CNS) disturbances. Poor feeding is one of the gastrointestinal symptoms common to this client population. Fluid and electrolyte balance must be maintained, and adequate nutrition provided. These infants often have a poor suck reflex and may need to be fed via gavage.

A primigravida has just delivered a healthy infant girl. The nurse is about to administer erythromycin ointment in the infant's eyes when the mother asks, "What is that medicine for?" The nurse responds: a. "It is an eye ointment to help your baby see you better." b. "It is to protect your baby from contracting herpes from your vaginal tract." c. "Erythromycin is given prophylactically to prevent a gonorrheal infection." d. "This medicine will protect your baby's eyes from drying out over the next few days."

ANS: C With the prophylactic use of erythromycin, the incidence of gonococcal conjunctivitis has declined to less than 0.5%. Eye prophylaxis is administered at or shortly after birth to prevent ophthalmia neonatorum. Erythromycin has no bearing on enhancing vision, is used to prevent an infection caused by gonorrhea, not herpes, and is not used for eye lubrication.

With regard to central nervous system injuries to the infant during labor and birth, nurses should be aware that: a. Intracranial hemorrhage (ICH) as a result of birth trauma is more likely to occur in the preterm, low-birth-weight infant. b. Subarachnoid hemorrhage (the most common form of ICH) occurs in term infants as a result of hypoxia. c. In many infants signs of hemorrhage in a full-term infant are absent and diagnosed only through laboratory tests. d. Spinal cord injuries almost always result from forceps-assisted deliveries.

ANS: C Abnormalities in lumbar punctures or red blood cell counts, for instance, or in visuals on computed tomography scan might reveal a hemorrhage. ICH as a result of birth trauma is more likely to occur in the full-term, large infant. Subarachnoid hemorrhage in term infants is a result of trauma; in preterm infants it is a result of hypoxia. Spinal cord injuries are almost always from breech births; they are rare today because cesarean birth often is used for breech presentation

In caring for the mother who has abused (or is abusing) alcohol and for her infant, nurses should be aware that: a. The pattern of growth restriction of the fetus begun in prenatal life is halted after birth, and normal growth takes over. b. Two thirds of newborns with fetal alcohol syndrome (FAS) are boys. c. Alcohol-related neurodevelopmental disorders not sufficient to meet FAS criteria (learning disabilities, speech and language problems) are often not detected until the child goes to school. d. Both the distinctive facial features of the FAS infant and the diminished mental capacities tend toward normal over time.

ANS: C Some learning problems do not become evident until the child is at school. The pattern of growth restriction persists after birth. Two thirds of newborns with FAS are girls. Although the distinctive facial features of the FAS infant tend to become less evident, the mental capacities never become normal.

A plan of care for an infant experiencing symptoms of drug withdrawal should include: a. Administering chloral hydrate for sedation. b. Feeding every 4 to 6 hours to allow extra rest. c. Swaddling the infant snugly and holding the baby tightly. d. Playing soft music during feeding.

ANS: C The infant should be wrapped snugly to reduce self-stimulation behaviors and protect the skin from abrasions. Phenobarbital or diazepam may be administered to decrease central nervous system (CNS) irritability. The infant should be fed in small, frequent amounts and burped well to diminish aspiration and maintain hydration. The infant should not be stimulated (such as with music) because this will increase activity and potentially increase CNS irritability.

Near the end of the first week of life an infant who has not been treated for any infection develops a copper-colored, maculopapular rash on the palms and around the mouth and anus. The newborn is showing signs of: a. Gonorrhea. c. Congenital syphilis. b. Herpes simplex virus infection. d. Human immunodeficiency virus.

ANS: C The rash is indicative of congenital syphilis. The lesions may extend over the trunk and extremities

Human immunodeficiency virus (HIV) may be perinatally transmitted: a. Only in the third trimester from the maternal circulation. b. By a needlestick injury at birth from unsterile instruments. c. Only through the ingestion of amniotic fluid. d. Through the ingestion of breast milk from an infected mother.

ANS: D Postnatal transmission of HIV through breastfeeding may occur. Transmission of HIV from the mother to the infant may occur transplacentally at various gestational ages. Transmission close to or at the time of birth is thought to account for 50% to 80% of cases.

With regard to hemolytic diseases of the newborn, nurses should be aware that: a. Rh incompatibility matters only when an Rh-negative offspring is born to an Rh-positive mother. b. ABO incompatibility is more likely than Rh incompatibility to precipitate significant anemia. c. Exchange transfusions frequently are required in the treatment of hemolytic disorders. d. The indirect Coombs' test is performed on the mother before birth; the direct Coombs' test is performed on the cord blood after birth.

ANS: D An indirect Coombs' test may be performed on the mother a few times during pregnancy. Only the Rh-positive offspring of an Rh-negative mother is at risk. ABO incompatibility is more common than Rh incompatibility but causes less severe problems; significant anemia, for instance, is rare with ABO. Exchange transfers are needed infrequently because of the decrease in the incidence of severe hemolytic disease in newborns from Rh incompatibility.

When attempting to diagnose and treat developmental dysplasia of the hip (DDH), the nurse should: a. Be able to perform the Ortolani and Barlow tests. b. Teach double or triple diapering for added support. c. Explain to the parents the need for serial casting. d. Carefully monitor infants for DDH at follow-up visits.

ANS: D Because DDH often is not detected at birth, infants should be monitored carefully at follow-up visits. The Ortolani and Barlow tests must be performed by experienced clinicians to prevent fracture or other damage to the hip. Double or triple diapering is not recommended because it promotes hip extension, thus worsening the problem. Serial casting is done for clubfeet, not DDH.

The priority nursing diagnosis for a newborn diagnosed with a diaphragmatic hernia would be: a. Risk for impaired parent-infant attachment. b. Imbalanced nutrition: less than body requirements. c. Risk for infection. d. Impaired gas exchange.

ANS: D Herniation of the abdominal viscera into the thoracic cavity may cause severe respiratory distress and represent a neonatal emergency. Oxygen therapy, mechanical ventilation, and the correction of acidosis are necessary in infants with large defects. Although the nursing diagnoses of Risk for impaired parent-infant attachment, Imbalanced nutrition: less than body requirements, and Risk for infection may be factors in providing care to a newborn with a diaphragmatic hernia, the priority nursing diagnosis relates to the oxygenation issues arising from the lung hypoplasia that occurs with diaphragmatic hernia.

What bacterial infection is definitely decreasing because of effective drug treatment? a. Escherichia coli infection c. Candidiasis b. Tuberculosis d. Group B streptococcal infection

ANS: D Penicillin has significantly decreased the incidence of group B streptococcal infection. E. coli may be increasing, perhaps because of the increasing use of ampicillin (resulting in a more virulent E. coli resistant to the drug). Tuberculosis is increasing in the United States and Canada. Candidiasis is a fairly benign fungal infection.

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, although the arm and shoulder may be immobilized for comfort.

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 newborn's distress is most likely to be: a. Hypoglycemia. c. Respiratory distress syndrome. b. Phrenic nerve injury. 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.
