Chapter 35 Flashcards
- A macrosomic infant is born after a difficult forceps-assisted delivery. After stabilization, the infant is weighed, and the birth weight is 4550 g (9 lb, 6 oz). What is the nurse’s first priority?
a. Leave the infant in the room with the mother.
b. Immediately take the infant to the nursery.
c. Perform a gestational age assessment to determine whether the infant is large for gestational age.
d. Frequently monitor blood glucose levels, and closely observe the infant for signs of hypoglycemia.
ANS: D
Regardless of gestational age, this infant is macrosomic (defined as fetal weight more than 4000 g) and is at high risk for hypoglycemia, which affects many macrosomic infants. Blood glucose levels should be frequently monitored, and the infant should be closely observed for signs of hypoglycemia. Close observation can be achieved in the mother’s room with nursing interventions. However, depending on the condition of the infant, observation may be more appropriate in the nursery.
- A 3.8-kg infant was vaginally delivered at 39 weeks after a 30-minute second stage. A nuchal cord was found at delivery. After birth, the infant is noted to have petechiae over the face and upper back. Which information regarding petechiae is most accurate and should be provided to the parents?
a. Are benign if they disappear within 48 hours of birth
b. Result from increased blood volume
c. Should always be further investigated
d. Usually occur with a forceps-assisted delivery
ANS: A
Petechiae, or pinpoint hemorrhagic areas, acquired during childbirth may extend over the upper portion of the trunk and face. These lesions are benign if they disappear within 2 days of childbirth and no new lesions appear. Petechiae may result from decreased platelet formation. In this situation, the presence of petechiae is most likely a soft-tissue injury resulting from the nuchal cord at birth. Unless the lesions do not dissipate in 2 days, alarming the family is not necessary. Petechiae usually occur with a breech presentation vaginal birth.
- What information regarding a fractured clavicle is most important for the nurse to take into consideration when planning the infant’s care?
a. Prone positioning facilitates bone alignment.
b. No special treatment is necessary.
c. Parents should be taught range-of-motion exercises.
d. The shoulder should be immobilized with a splint.
ANS: B
Fractures in newborns generally heal rapidly. Except for gentle handling, no accepted treatment for a fractured clavicle exists. Movement should be limited, and the infant should be gently handled. Performing range-of-motion exercises on the infant is not necessary. A fractured clavicle does not require immobilization with a splint.
- Which conditions are infants of diabetic mothers (IDMs) at a higher risk for developing?
a. Iron deficiency anemia
b. Hyponatremia
c. Respiratory distress syndrome
d. Sepsis
ANS: C
IDMs are at risk for macrosomia, birth trauma, perinatal asphyxia, respiratory distress syndrome, hypoglycemia, hypocalcemia, hypomagnesemia, cardiomyopathy, hyperbilirubinemia, and polycythemia. IDMs are not at risk for anemia, hyponatremia, or sepsis.
- 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 per minute 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. Based on the maternal history, what is the most likely cause of this newborn’s distress?
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) suggest sepsis. A differential diagnosis can be difficult because signs of sepsis are similar to noninfectious problems such as anemia and hypoglycemia. Phrenic nerve injury is usually the result of traction on the neck and arm during childbirth and is not applicable to this situation. The earliest signs of sepsis are characterized by lack of specificity (e.g., lethargy, poor feeding, irritability), not respiratory distress syndrome.
- What is the most important nursing action in preventing neonatal infection?
a. Good handwashing
b. Isolation of infected infants
c. Separate gown technique
d. Standard Precautions
ANS: A
Virtually all controlled clinical trials have demonstrated that effective handwashing is responsible for the prevention of health care–associated infection in nursery units. Overcrowding must be avoided in nurseries, and infants with infectious processes should be isolated. Separate gowns should be worn in caring for each infant in the special care nursery. Soiled linens should be disposed of in an appropriate manner. 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. Ideally infants should remain with their mothers.
- A pregnant woman arrives at the birth unit 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. Based on her infant’s physical findings, this woman should be questioned about her use of which substance during pregnancy?
a. Alcohol
b. Cocaine
c. Heroin
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 (IUGR). The infant may have a shrill cry and sleep-cycle disturbances and may exhibit 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.
- For an infant experiencing symptoms of drug withdrawal, which intervention should be included in the plan of care?
a. Administering chloral hydrate for sedation
b. Feeding every 4 to 6 hours to allow extra rest between feedings
c. Snugly swaddling the infant and tightly holding the baby
d. Playing soft music during feeding
ANS: C
The infant should be snugly wrapped to reduce self-stimulation behaviors and to 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 stimulation will increase activity and potentially increase CNS irritability.
- Human immunodeficiency virus (HIV) may be transmitted perinatally or during the postpartum period. Which statement regarding the method of transmission is most accurate?
a. Only in the third trimester from the maternal circulation
b. From the use of 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 the HIV through breastfeeding and breast milk may occur. Transmission of the HIV from the mother to the fetus may occur through the placenta at various gestational ages. Transmission of the HIV from the use of unsterile instruments is highly unlikely; most health care facilities must meet sterility standards for all instrumentation.
- Which substance, when abused during pregnancy, is the most significant cause of cognitive impairment and dysfunction in the infant?
a. Alcohol
b. Tobacco
c. Marijuana
d. Heroin
ANS: A
Alcohol abuse during pregnancy is recognized as one of the leading causes of neurodevelopmental disorders in the United States. Alcohol is a teratogen; maternal ethanol abuse during gestation can lead to identifiable fetal alcohol spectrum disorders that include alcohol-related neurodevelopmental disorders. Cigarette smoking is linked to adverse pregnancy outcomes; the risk for placenta previa, placenta abruption, and premature rupture of membranes is twice that of nonsmokers. Marijuana is the most common illicit drug used by pregnant women. Marijuana crosses the placenta, and its use during pregnancy can result in shortened gestation and a higher incidence of IUGR. Heroin crosses the placenta and often results in IUGR, stillbirth, and congenital anomalies.
- During a prenatal examination, a woman reports having two cats at home. The nurse informs her that she should not be cleaning the litter box while she is pregnant. The client questions the nurse as to why. What is the nurse’s most appropriate response?
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 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 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. Approximately 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 cleaning the litter boxes is “just gross,” this statement is not appropriate, fails to answer the client’s question, and is not the nurse’s best response. E. coli is found in normal human fecal flora and is not transmitted by cats.
- 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?” How should the nurse respond?
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 prophylactically given 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 given to prevent infection, not for lubrication.
- The nurse should be cognizant of which condition related to skeletal injuries sustained by a neonate during labor or childbirth?
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
Approximately 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.
- The nurse is evaluating a neonate who was delivered 3 hours ago by vacuum-assisted delivery. The infant has developed a cephalhematoma. Which statement is most applicable to the care of this neonate?
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 vacuum-assisted deliveries.
ANS: C
Abnormalities in lumbar punctures or red blood cell counts, for instance, or in visuals on computed tomographic (CT) scans 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; however, spinal cord injuries are rare today because cesarean birth is used for breech presentation.
- 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 displaying signs and symptoms of which condition?
a. Gonorrhea
b. Herpes simplex virus (HSV) infection
c. Congenital syphilis
d. HIV
ANS: C
A copper-colored maculopapular rash is indicative of congenital syphilis with lesions that may extend over the trunk and extremities. This rash is not an indication that the neonate has contracted gonorrhea. Rather, the neonate with gonorrheal infection might have septicemia, meningitis, conjunctivitis, and scalp abscesses. Infants affected with the HSV display growth restriction, skin lesions, microcephaly, hypertonicity, and seizures. Typically, the HIV-infected neonate is asymptomatic at birth. Most often the infant develops an opportunistic infection and rapid progression of immunodeficiency.
