testbank maternal

25. A nurse sees a baby whose left arm is in a flexed position and is held in place by pinning the cuff of the baby's T-shirt sleeve to the opposite shoulder. What can the nurse conclude about this baby? A. Broken clavicle B. Broken wrist C. Duchenne-Erb paralysis D. Klumpke paralysis

ANS: A A broken clavicle is often treated by pinning the infant's arm as described. Duchenne-Erb paralysis is a type of brachial plexus injury caused by nerve injury to C5-T1. Klumpke paralysis is another type of brachial plexus injury caused by nerve injury to C5-C7. Wrist fractures in infants are uncommon.

5. The nurse is assessing the cardiovascular status of a newborn. Which of the following findings indicates adequate systemic circulation? A. Capillary refill 2 seconds B. Capillary refill 4 seconds C. Pale mucous membranes in a dark-skinned baby D. Truncal cyanosis

ANS: A On assessment, the systemic circulation is deemed adequate if the newborn exhibits a brisk capillary refill and stable blood pressure. Capillary refill in less than 3 seconds is considered adequate. A refill time greater than 4 seconds may be indicative of an underlying condition, such as sepsis, hypoxia, or cardiovascular or central nervous system compromise. A dark-skinned baby should have pink mucous membranes. Acrocyanosis is normal, but a cyanotic trunk is not.

7. An infant in the NICU has persistent pulmonary hypertension. The nurse places highest priority on which of the following nursing diagnoses? A. Ineffective tissue perfusion: cardiopulmonary B. Ineffective tissue perfusion: cerebral C. Ineffective tissue perfusion: peripheral D. Ineffective tissue perfusion: neurovascular

ANS: A Persistent pulmonary hypertension has a right-to-left shunting of blood across the foramen ovale and through the ductus arteriosus of the heart. Therefore, the appropriate nursing diagnosis prioritizes the cardiovascular and pulmonary systems.

2. The pediatric nurse is receiving a morning report via phone call on an infant who will be arriving in the neonatal intensive care unit. The report indicates that shoulder dystocia may have occurred during the birth process. The nurse assesses the neonate as at risk for which additional condition? A. Brachial plexus injury B. Hyperbilirubinemia C. Hypoglycemia D. Intracranial hemorrhage

ANS: A Risk factors for a brachial plexus injury include LGA or macrosomic newborns, newborns with a diabetic mother, instrument delivery, prolonged labor, shoulder dystocia, and multiparity.

42. A nurse is discharging parents and their new infant. When assisting the family to place the infant in a car seat, which observation leads the nurse to reinforce teaching? A. The baby is wearing a sack-type sleeper. B. The baby is wearing a single layer of clothes. C. The parent checks the temperature of the car seat. D. A rear-facing car seat is in the back seat.

ANS: A Sack-type sleepers are not recommended for wearing in a child safety seat because the straps may not fit properly. The other observations are appropriate.

16. A nurse assesses an infant using the Premature Infant Pain Profile and gives the baby a score of 19. What action by the nurse is most appropriate? A. Administer morphine (Astramorph). B. Give an oral sucrose solution. C. Provide nonnutritive sucking. D. Swaddle and cuddle the infant.

ANS: A The Premature Infant Pain Profile is a common pain tool used in NICUs. Scores range from 0to 21. The higher the score, the worse pain the baby is in. A score of 19 indicates severe pain, and the nurse needs to administer morphine sulfate. The other options are all useful treatments for pain, but in this case, the severity of the pain warrants the opioid analgesic.

41. A student nurse is caring for an infant who was just circumcised. What assessment finding should the student report to the registered nurse? A. No voiding for 8 hours B. Slight blood on the diaper C. Swelling on the glans penis D. Wishes to be held continuously

ANS: A The nurse should assess for the first voiding after a circumcision to evaluate for urinary obstruction related to injury or swelling. Slight blood on the diaper would be expected. Some swelling may occur and does not cause concern unless it blocks the urethra. After a procedure, it is normal for an infant to wish to be held and comforted.

12. A nurse is preparing to admit a newborn to the NICU who weighs 1,750 g. What classification does the nurse use to describe this infant? A. Extremely low birth weight B. Low birth weight C. Normal birth weight D. Very low birth weight

ANS: B A normal birth weight baby is between the 10th and 90th percentile on the developmental growth chart for developmental age. A low-birth-weight baby is a newborn weighing less than 2,500 g. A very-low-birth-weight infant weighs less than 1,500 g, and an extremely low-birth-weight infant weighs less than 1,000 g.

31. An infant with gastroesophageal reflux disease (GERD) is being discharged home. Which of the following is the priority topic the nurse plans to include in the teaching plan? A. Managing a multi-medication regime at home B. Positioning the infant during feeding and sleeping C. Type of formula to best prevent episode of GERD D. When to return for surgical correction of the bowel

ANS: B GERD is common in infants and is not always treated. Prevention includes maintaining an upright position when feeding and feeding the baby slowly. Medications are not always used, but when given, they consist of proton-pump inhibitor or medication to increase gastric motility. Treatment does not include a multi-drug regimen. Formula type is not related. GERD is an upper gastrointestinal disorder, so surgical correction of the bowel is not indicated.

19. A nurse has given a premature hypoglycemic infant an IV glucose solution. How would the nurse best determine if the goals for this treatment have been met? A. Blood glucose is 42 mg/dL. B. Blood glucose is 58 mg/dL. C. The baby has a normal-sounding cry. D. The baby is sucking vigorously.

ANS: B Many nurseries consider a high-risk newborn hypoglycemic when blood glucose readings are below 50-60 mg/dL. For this premature infant, a glucose of 58 mg/dL indicates that treatment has been effective. A blood glucose of 42 mg/dL would be acceptable for a healthy newborn. One sign of hypoglycemia is a high-pitched or weak cry, so this might be an assessment finding associated with euglycemia; however, it is not as specific as a laboratory test. Vigorous sucking is not related.

33. The perinatal nurse notes that a newborn does not seem to have an opening inside the anal ring. Which action by the nurse takes priority? A. Ask the mother how well the infant is eating. B. Assess the abdomen and notify the physician. C. Facilitate laboratory studies for kidney function. D. Reassure the parents that this is a normal deviation.

ANS: B This infant may have an imperforate anus, a condition that is an emergency, as the infant cannot pass stool. The nurse should quickly assess the baby's abdomen for distention and firmness and notify the physician or health-care provider. The other actions are not warranted.

11. What action by the nurse is most important to prevent respiratory depression in a newly born infant? A. Bathe the infant in warm water before giving to the mother. B. Dress the infant in warm clothing and place in a warmer. C. Dry the infant and place on the mother's bare chest. D. Turn the delivery room temperature up to 85°F (29.4°C

ANS: C Cold stress can lead to respiratory depression. The nurse should immediately dry off a newly born infant and either place him in skin-to-skin contact with the mother or put him in a radiant warmer.

1. The nurse is assessing the neonate's skin and notes the presence of small irregular red patches on the cheeks that turn into single yellow pimples on the baby's chest. What treatment and care does the nurse recommend to the parents to help resolve this rash? A. Apply aloe vera lotion to lesions and skin. B. Apply hormonal skin cream twice a day. C. None; it will disappear within about a month. D. Vigorously wash and cleanse the baby's skin.

ANS: C Erythema toxicum is a newborn rash that consists of small, irregular flat red patches on the cheeks that develop into singular, small yellow pimples appearing on the chest, abdomen, and extremities. The etiology is unknown and it may persist for up to a month before resolving on its own.

12. A nurse assesses a 2-hour-old infant's temperature and notes it to be 97.7°F (36.5°C). What action by the nurse is most appropriate? A. Document the findings and continue to monitor. B. Ensure the baby is wearing a hat. C. Place the baby in a pre-warmed incubator. D. Tightly swaddle the baby.

ANS: A A normal axillary temperature for an infant is 97.7°-98.6° F (36.5°-37° C) within 2-3 hours after birth. The nurse should document the findings and continue to monitor per institutional policy. No further action is needed

46. A nurse reads in the chart that a baby has a positive crossed extension reflex and asks a more experienced nurse to demonstrate this assessment. How does the nurse perform the assessment? A. Place the infant supine, stimulate one foot, and watch for reaction of the other leg. B. Tap the infant's forehead gently, and assess for blinking for the first few taps. C. Watch the infant attempt to crawl when he is placed on his abdomen. D. With the infant prone, stroke one side of the spine; watch the buttocks curve toward the stimulation.

ANS: A A positive crossed extension reflex occurs when the infant is supine and one foot is stimulated. The infant should flex, adduct, and then extend the opposite leg. Tapping the forehead is part of the glabellar reflex assessment. The crawling reflex is present when the infant attempts to crawl while prone. The Galant reflex (or trunk incurvation reflex) is assessed with the infant in a prone position. Stroke one side of the vertebral column and watch the baby's buttocks curve toward the side where the stimulation occurred.

13. A small-for-gestational-age (SGA) newborn is admitted to the NICU. The nurse notes that the baby's head circumference is in the 68th percentile for gestational age, but the baby's weight is under the 10th percentile. The baby also has a scaphoid abdomen and long fingernails. How does the nurse classify this baby in the handoff report? A. Asymmetrical intrauterine growth restriction B. Cold-stressed infant C. Intrauterine growth retardation D. Small for gestational age

ANS: A An SGA newborn has a weight under the 10th percentile for gestational age. This results from intrauterine growth restriction (IUGR). A baby with symmetrical IUGR has low weight plus a head circumference that falls below the 10th percentile. Asymmetrical IUGR results in weight under the 10th percentile and a head of an appropriate size. The terminology "intrauterine growth retardation" is no longer used. This baby is not cold stressed.

18. A faculty member explains to a nursing student that the best way to prevent hemorrhage from injuries in a neonate is which of the following? A. Administer vitamin K1 phytonadione (AquaMEPHYTON). B. Handle the infant carefully while wearing soft gloves. C. Keep the infant swaddled in several layers of blankets. D. Teach the parents how to trim the baby's fingernails.

ANS: A AquaMEPHYTON is given to newborns to promote normal blood clotting. The infant's intestinal tract is sterile at birth and does not have the bacteria needed to create vitamin K, a necessary component of normal clotting. Giving the infant an injection of vitamin K promotes blood clotting and prevents bleeding.

18. A mother brings her 1-week-old baby to the clinic with complaints that the baby is not eating well. The mother is attempting to bottle feed about 120 mL every 2 hours. What action by the nurse is best? A. Explain that this is too much volume at one time. B. Have the mother demonstrate her feeding and burping technique. C. Reassure the mother that the baby is eating fine. D. Weigh the baby and plot her weight on a graph

ANS: A At 1 week of age, an infant's stomach has a capacity of about 90 mL. Attempting to feed 120 mL is too much at one time. Weighing the baby and plotting her growth and having the mother demonstrate feeding and burping techniques are not incorrect, but the mother needs additional information to safely feed her baby. Simply reassuring the mother does not give her the information she needs to feed the baby appropriately.

28. A nurse notes that an infant has a drooping tongue, which causes difficulty with feeding. What cranial nerve should the nurse assess further? A. Facial B. Olfactory C. Trigeminal D. Vagus

ANS: A Birth-related damage to the 7th cranial nerve (facial) can lead to drooping tongue or mouth, unequal movement of the cheek muscles, or inappropriate eyelid movement.

2. The nurse completes an initial newborn examination. The nurse's findings include the following: heart rate, 136 beats/minute; respiratory rate, 64 breaths/minute; temperature, 98.2°F (36.8°C). The nurse also documents a heart murmur, absence of bowel sounds, symmetry of ears and eyes, no grunting or nasal flaring, and full range of movement of all extremities. Which finding requires immediate consultation with the health-care provider? A. Absent bowel sounds B. Heart murmur C. Respiratory rate D. Temperature

ANS: A Bowel obstruction in the neonate is often first identified by an absence of bowel sounds in a small, distinct section of the intestines; therefore, this finding should be reported. The other findings are normal (it is not uncommon to hear murmurs in infants less than 24 hours old)

3. The nursery nurse notes the presence of diffuse edema on a newborn baby's head. Review of the birth record indicates that her mother experienced a prolonged labor and difficult childbirth. What action by the nurse is best? A. Document the findings in the infant's chart. B. Measure head circumference every 12 hours. C. Prepare to administer IV osmotic diuretics. D. Transfer the baby to the NICU for monitoring

ANS: A Caput succedaneum is diffuse edema that crosses the cranial suture lines and disappears without treatment during the first few days of life. It often is the result of a traumatic or difficult birth. The nurse should document the findings. No other action is needed.

15. What action by the nurse takes priority in safeguarding a neonate's safety and well-being? A. Ensuring that the baby wears an abduction alarm B. Keeping the baby with the mother at all times C. Requiring visitors to the unit to wear identification D. Providing proper identification and constant surveillance

ANS: A Careful and continuous monitoring of infants and proper identification per agency protocol is the best way to ensure a baby's safety and well-being. Some institutions may use abduction alarms. Keeping the baby with the mother at all times may not always be possible. Proper identification of visitors is important, but is not comprehensive enough to be the priority.

21. A term infant's initial blood glucose level is 42 mg/dL. What action by the nurse is most appropriate? A. Document the findings in the infant's chart. B. Encourage the mother to initiate breastfeeding. C. Prepare to administer intravenous glucose. D. Recheck the blood glucose in 2 hours.

ANS: A For term infants, a normal blood glucose is greater than 35 mg/dL or a plasma concentration of greater than 40 mg/dL. This infant's blood glucose is normal, so the nurse should document the findings. No other action is necessary.

6. An infant who is possibly infected with herpes simplex infection is being dismissed. What medication should the nurse anticipate instructing the parents on giving? A. Acyclovir (Avirax) B. Ampicillin (Omnipen) C. Cephtriaxone (Rocephin) D. Hydroxyzine (Atarax)

ANS: A Herpes simplex is a viral infection, so an antiviral such as acyclovir is warranted. Antibiotics such as ampicillin and cephtriaxone are not used. Hydroxyzine is for itching.

14. What action by the nurse is most important to prevent hemorrhagic disease of the newborn? A. Administer vitamin K1 phytonadione (AquaMEPHYTON). B. Assess daily hemoglobin and hematocrit levels. C. Coordinate laboratory sticks to minimize blood loss. D. Handle the infant gently to prevent injury.

ANS: A Infants are given one dose of vitamin K during initial care and assessment to prevent hemorrhagic disease of the newborn. Assessing laboratory values does not prevent a condition from occurring, but it might alert health-care providers to changes in status. Minimizing blood loss and gentle handling do not prevent hemorrhagic disease, although both are good ideas for other reasons.

27. A nurse is assessing an infant who has a large bruise around his neck and face from a nuchal cord. What other assessment finding correlates with this condition? A. Elevated serum bilirubin B. Irritability with gentle handing C. Large-for-gestational-age measurements D. Obvious vertebral defects

ANS: A Infants born with a nuchal cord often demonstrate significant bruising to the face and neck. This may be upsetting to the parents. Irritability with handling might be related to damage from birth trauma. Large-for-gestational-age infants often have bruising related to extraction techniques during a difficult birth. Obvious vertebral defects are associated with neural tube anomalies and can be seen in children with hairy pigmented skin lesions and hairy nevi located in the posterior midline area near the spinal column.

20. A mother worries about her infant feeling pain during a heel stick for a blood test. What action by the nurse is best? A. Encourage breastfeeding during the heel stick. B. Ice the infant's heel prior to the blood draw. C. Massage the infant's heel after the needle stick. D. Reassure the mother that infants don't feel pain.

ANS: A Infants feel pain and remember painful procedures. Breastfeeding has been shown to be an effective, cost-effective, and safe intervention to decrease infants' sensation of pain. Ice and massage would not be warranted

37. Prior to giving a newborn the first bath, what action by the nurse is most appropriate? A. Assess the infant's temperature. B. Ensure the tub water is not too hot. C. Obtain all of the needed supplies. D. Take the baby's blood pressure.

ANS: A Preventing temperature instability is a critical nursing action when bathing an infant in the hospital. If the infant's temperature is within normal limits, the baby can be given a sponge bath. After the umbilical cord stump falls off, the infant can be bathed in a tub of water. Obtaining needed supplies is always important prior to performing any procedure, but this is not as important as maintaining safety. Taking the blood pressure is not needed.

14. A neonate's 5-minute Apgar assessment reveals the following: active motion; pulse, 126 beats/minute; grimace and coughing during suctioning; appearance, good color all over; and respirations slightly irregular with weak cry. What action by the nurse is most appropriate? A. Assess oxygen saturation and administer oxygen if needed. B. Document the findings in the chart and begin the identification process. C. Facilitate bonding and help the mother initiate breastfeeding if desired. D. Place the baby in skin-to-skin contact on the mother's bare abdomen.

ANS: A The baby's 5-minute Apgar score is 8 (motion, 2; pulse, 2; grimace, 2; appearance, 1; respirations, 1). If a 5-minute Apgar score is less than 9, the nurse should stabilize the infant instead of leaving the baby with the parents in the birthing unit. Because it appears that this baby's problems are related to either oxygenation or perfusion, the nurse should assess the oximetry reading and administer oxygen if neede

21. What assessment finding indicates to the nurse that goals for the diagnosis of ineffective thermoregulation related to newborn's immature temperature regulatory system have been met? A. Axillary temperature is 98.1°F (36.7°C). B. Fluctuations in infant's temperature cease. C. Baby stops shivering and falls asleep. D. Rectal temperature is 101.0°F (38.3°C).

ANS: A The normal range for newborn temperature is 97.7°-98.6°F (36.5°-37.0°C). A stable temperature within this range demonstrates that goals for this diagnosis have been met. "Fluctuations in infant's temperature cease" is vague, and the temperature may have stabilized at a level that is too high or too low. Infants can't shiver. Axillary, not rectal, temperatures are taken; the temperature may also be assessed via continuous skin probe, or tympanic or temporal artery thermometry.

23. A diabetic woman had a cesarean delivery and her baby is noted to have a respiratory rate of 82 breaths/minute with retractions. The baby's blood gas analyses are as follows: pH, 7.20; PCO2, 52 mm Hg; PaO2, 80 mm Hg; PHCO3-, 21 mEq/L. What is an important safety measure the nurse should plan to implement when caring for this infant? A. Ensure the CPAP pressures do not exceed 6 cm H2O. B. Maintain secure position of the endotracheal tube with tape. C. Place the skin temperature sensor over the liver border. D. Plan to check the baby's blood glucose every 2 hours.

ANS: A This baby is at risk for, and has signs of, transient tachypnea of the newborn (TTN). These babies are often started on CPAP with pressures of 206 cm H2O. Pressures higher than that can cause septal damage and necrosis. The other interventions are not appropriate.

14. A nurse is assessing a newborn infant and notes cool skin, poor feeding attempts, and bradycardia. Which action by the nurse is best? A. Obtain a rectal temperature. B. Place the infant in a radiant warmer. C. Provide a neutral thermal environment. D. Put the infant on a warm pack.

ANS: A This infant appears to be hypothermic, but the diagnosis of hypothermia is based on a rectal temperature in addition to the characteristic signs, so the nurse needs to do that first. Then the nurse can place the infant under a radiant warmer or on a warm pack. Infants should be provided with a neutral thermal environment at all times, but this will not warm this baby fast enough on its own.

27. A preterm infant was born at 31 weeks and has been admitted to the NICU. The nurse notes expiratory grunting, nasal flaring, and cyanosis on room air. Which laboratory findings would correlate with this condition? A. PaCO2: 56 mm Hg B. PaO2: 76 mm Hg C. pH: 7.30 D. SaO2: 94%

ANS: A This premature infant is at risk for respiratory distress syndrome (RDS) and has classic signs of the disorder. Laboratory values consistent with this condition are hypercarbia, metabolic acidosis, and low measured levels of oxygen either by arterial blood gas analysis or oxygen saturation. Normal PaCO2 for infants is 35-40 mm Hg, so this level is high. The other values are normal.

32. The nurse notes swelling in the scrotum of a newborn infant. Transillumination reveals a reddish-yellow reflection. What action by the nurse is best? A. Document the findings and reassure the parents. B. Elevate the scrotum and apply ice for 20 minutes. C. Notify the health-care provider immediately. D. Obtain informed consent for emergent surgery.

ANS: A When the nurse assesses a swollen scrotum, it is important to determine that the scrotal sac does not contain entrapped bowel or a mass. Transillumination can determine the presence of a mass when the light directed at the scrotum does not produce a reflection. A reddish-yellow reflection indicates fluid, which will be reabsorbed on its own. The nurse should document the findings and reassure the parents. No further action is needed.

35. A nurse is preparing to discharge an infant who has developmental dysplasia of the hip (DDH). What discharge instruction would be most important? A. How to correctly perform Ortolani's maneuver B. How to properly use the Pavlik harness C. When to return for corrective surgery D. Where to take the baby to be fit for corrective shoes

ANS: B A baby with DDH will be placed in a special splint, most often the Pavlik harness, to keep the legs in a position of abduction. The harness is worn continuously for 3-6 months, during which time bone growth helps create a normal hip joint. Ortolani's maneuver is an assessment for DDH. Surgery may be required, but not until it has been determined that bone growth is not creating a normally shaped hip joint. Corrective shoes are not needed.

10. The nursing professor is explaining to a class of students that which chemical factor in the blood directly leads to the initiation of respirations in the newborn? A. Bilirubin B. Carbon dioxide C. High arterial pH D. Low arterial pH

ANS: B All newborns have a brief period of asphyxia during which they become hypoxic, leading to lowered pH. Subsequently carbon dioxide levels begin to rise and this stimulates the respiratory center in the brain to initiate respirations.

9. In order to promote thermal stabilization in a neonate, which action by the nurse is best? A. Lay the infant in an incubator. B. Place the infant in skin-to-skin contact with the mom. C. Put a knitted cap on the baby's head. D. Wrap the baby in warmed blankets.

ANS: B All options will help the baby maintain a normal temperature, but ideally the nurse places the infant in skin-to-skin contact on the mother's abdomen.

17. A nurse is providing care to several neonates. In giving the infants prophylactic medication to prevent ophthalmia neonatorum, which ordered medication should the nurse question giving? A. Erythromycin (Eyemycin) B. Penicillin C. Silver nitrate (Dey-Drops) D. Tetracycline (Ocudox)

ANS: B Penicillin is not used for prophylaxis against ophthalmia neonatorum. The other medications are appropriate.

19. A new nurse is preparing to administer erythromycin (Eyemycin) to an infant. What action by the new nurse would lead the precepting nurse to intervene? A. Applies the medication in a thin strip to each eye B. Prepares to administer the medication 4 hours after birth C. Starts to administer the medication at the inner canthus D. Teaches the parents that mild irritation can occur

ANS: B Prophylactic medication to prevent ophthalmia neonatorum, such as erythromycin, needs to be administered within 1 hour of birth. The other actions are appropriate.

38. In preparing a family for discharge from the perinatal unit, which method of nail care does the nurse teach as the preferred method? A. Cutting the nails with sharp scissors B. Filing the nails with a fine emery board C. Letting the nails break off naturally D. Wrapping the infant's hands in mittens

ANS: B Several options exist for nail care to keep the infant from scratching her face. The nails can be cut, but there is a risk of damaging the delicate skin around the nail. This is best done while the baby sleeps. Letting the nails break off is not a good option, as the child may injure herself before they break. Covering the hands with mittens or a tee shirt is a possible option, but does not allow the child to suck on the fingers for self-soothing. The best option is to file the nails gently with a fine-grained emery board.

18. A nurse assesses a premature infant and finds shearing injuries to the infant's arms and legs. What action by the nurse is best? A. Apply emollient lotion to the skin. B. Assess the baby for pain. C. Order hypoallergenic crib linens. D. Place sheepskin under the baby.

ANS: B Skin breakdown due to rubbing and shearing is a common occurrence in a baby with unrelieved pain. The nurse should first assess the baby for pain and treat accordingly. Emollient should not be used on open skin. Hypoallergenic linens are not warranted. Sheepskin may or may not be helpful, but the best action is to assess and treat any pain.

21. The nurse caring for small-for-gestational-age (SGA) infants assesses them for attainment of outcomes related to nursing diagnoses. Which assessment finding best demonstrates attainment of priority outcomes? A. Body temperature of 97.5°F (36.4° C) B. Gains weight regularly C. Parents visit daily D. Skin remains intact

ANS: B The SGA infant has several important nursing diagnoses, including risk for activity intolerance related to increased metabolic needs, risk for ineffective feeding pattern related to increased metabolic need, and nutritional imbalance related to hypoglycemia. The fact that this infant is gaining weight demonstrates that he or she is meeting outcomes related to all three diagnoses. A body temperature of 97.5°F is too cool for removal of the baby from the incubator. Parental involvement may indicate no unmet psychosocial needs on their part, but physical diagnoses take precedence over psychosocial ones. Intact skin is a good finding, but risk for impaired skin integrity would not be a higher priority than the other three.

8. A neonatal nurse who is caring for newborns suggests the best time for a mother to first attempt breastfeeding is during which of the following stages of activity? A. First period of inactivity and sleep B. First period of reactivity C. Second period of inactivity and sleep D. Second period of reactivity

ANS: B The best stage for initiating breastfeeding is the first period of reactivity, which is the first period of active alert wakefulness that the infant displays immediately after birth. This first period of reactivity is an opportune time for the mother to initiate breastfeeding, if she wishes to do so.

22. A faculty member is supervising a student who is preparing to administer vitamin K1 phytonadione (AquaMEPHYTON) to an infant. What action by the student prompts the faculty member to intervene? A. Chooses a 25-gauge needle B. Draws up 0.5 mg/kg C. Gently rubs the injection site D. Uses a 1-mL syringe

ANS: B The dose of vitamin K1 phytonadione (AquaMEPHYTON) is 0.5 mg. It is not dosed according to weight. The other actions are appropriate

8. When assessing a newborn baby, which action should the nurse perform first? A. Auscultate the baby's heart and lungs. B. Don clean gloves before taking the baby. C. Record the parents' choice of name. D. Suction the nares and then the mouth.

ANS: B The nurse should observe standard precautions when handling a neonate until all blood and amniotic fluid has been removed to avoid possible infection. Then the nurse can take the baby and suction the baby's mouth, and then the nares if needed. Auscultating the baby's heart and lungs will occur later. The parents may not name the baby immediately, but even if they have, recording the name would not take priority over using standard precautions to prevent the spread of disease.

28. A premature infant has apnea of prematurity accompanied by bradycardia and desaturation. The infant was started on caffeine citrate (Cafcit), and the results from a blood level have just now returned. The infant's blood level of Cafcit is 2.3 mg/mL. What action by the nurse is most appropriate? A. Allow infant to grow out of the current Cafcit dose. B. Document results; maintain cardiorespiratory monitor. C. Inform parents that this blood level is therapeutic. D. Prepare for immediate intubation and ventilation.

ANS: B The therapeutic blood level for caffeine citrate (Cafcit) is 5-20 mg/mL; therefore, this blood level is subtherapeutic. The nurse should document the results and continue monitoring the infant with the cardiorespiratory monitor. The physician should also be informed so the dose can be adjusted if warranted. The child should not be allowed to outgrow the dose for weaning as the apnea and bradycardia episodes continue. The parents should not be informed that the level is therapeutic because it is not. There is no information leading to a conclusion that the infant needs intubation and mechanical ventilation.

5. A postterm baby is born, and the nurse notes that the baby has dirty-looking skin and nails. The baby has moderate respiratory distress with rales and rhonchi noted. What nursing care does the nurse anticipate providing for this infant? A. Giving the baby oxygen via an oxygen hood B. Increasing oxygenation by using CPAP C. Providing chest physiotherapy every 8 hours D. Sitting the infant upright to feed and sleep

ANS: B This baby has a "dirty" appearance because he or she was born in meconium-stained amniotic fluid, and the respiratory manifestations signal meconium aspiration syndrome. To improve oxygenation, treatment often involves CPAP. Less invasive means of providing oxygen (the hood) are usually not adequate. Chest physiotherapy is usually done every 3 to 4 hours. Sleeping and feeding in an upright position is helpful for GERD.

30. An infant who was stable for a day after birth now demonstrates pallor, tachycardia, tachypnea, and circumoral cyanosis. The parent asks how the child might have a heart problem when he was stable yesterday. What information by the nurse is most accurate? A. "Blood incompatibilities can cause this problem, so we will test the mother's blood." B. "Symptoms may not appear until fetal circulation routes begin to close after birth." C. "The extra blood from the umbilical cord may have kept the baby stable for a while." D. "Your baby may have gotten an infection during birth that now is causing problems."

ANS: B This baby has clinical manifestations of tetralogy of Fallot. While the ductus arteriosus remains patent, the infant remains stable. However, when the ductus begins closing after the first 24 hours of life, the infant's cardiovascular system becomes unstable and manifestations appear. The other statements are inaccurate.

15. A nurse is assessing a newborn who is jittery, diaphoretic, and hypothermic, and has poor feeding. What laboratory value would the nurse correlate with this condition? A. Bilirubin: 5 mg/dL B. Blood glucose: 32 mg/dL C. Hematocrit: 50% D. White blood cell count: 25,000/mm3

ANS: B This infant has signs of hypoglycemia, confirmed with a blood glucose level below 40 mg/dL (normal is 40-60 mg/dl). The other laboratory values are normal for a neonate

9. The nurse caring for a woman about to deliver a baby at 33 weeks' gestation knows that what factor might have accelerated surfactant production? A. Fetal hemolytic disorders B. Incorrect dates C. Maternal hypertension D. Multiple gestation

ANS: C A fetus has produced sufficient surfactant for independent respiratory function by about gestational weeks 34 to 36. Hence, a baby born at 33 weeks' gestation is at risk for not having enough surfactant. Factors that can lead to increased surfactant production include mothers with White classification D, F, and R diabetes; maternal hypertension; and maternal heroin addiction. Fetal hemolytic disorders and multiple gestation are risk factors for decreased surfactant production. Incorrect dates may be important, but this is not a factor that leads to increased surfactant production.

6. New parents are concerned that after initially breastfeeding their baby 2 hours after being born, she is sleeping soundly and will not awaken. What action by the nurse is most appropriate? A. Call the rapid response team. B. Document the neonate's behavior in the chart. C. Reassure the parents that this is normal. D. Stimulate the baby to wake her up

ANS: C After the initial period of reactivity, the infant falls into a deep sleep from which she is difficult to arouse. The nurse should reassure the parents that this is normal. Documentation is important, but the nurse first needs to care for the parents and baby by giving the parents information on normal newborn behaviors. Calling the rapid response team and stimulating the baby are both unnecessary.

39. The nurse teaching a family about bonding with their infant describes touch as an important facet of this process. What does the nurse understand is most important about touch and bonding? A. All newborn care must be completed through touch. B. Parental recognition occurs through touch. C. The neonate learns exclusively through touch. D. Touch accustoms the parent to the infant's body

ANS: C All options are at least partially correct. However, the most important point about touch and bonding is that all the infant learns during the neonatal period is conveyed through touch. Touch conveys warmth, love, pleasure, comfort, and security to the neonate.

29. A nurse is providing discharge teaching to parents of a newborn. The baby had no medical problems and is healthy other than having failed an automated auditory brainstem response (AABR) hearing test conducted in the nursery. What information does the nurse provide? A. AABR tests are conclusive and the baby is deaf. B. Background noise may have interfered with the test. C. The baby's hearing should be retested within 1 month. D. The baby should have another hearing test next week.

ANS: C Babies who fail a hearing screening test at birth should have a follow-up test within a month. The AARB test can be conducted in the presence of background noise. The results are not conclusive (it is a screening device), which is why the baby's hearing needs to be retested

4. A baby with brachial plexus injury is being discharged home. What information should the nurse include on the teaching plan? A. Encourage the baby to move the arm by holding out toys to reach for. B. Keep the baby's arm in the sling for 23 out of every 24 hours. C. Perform passive range-of-motion exercises to affected extremity. D. Return to the hospital on day 7 for microsurgical repair.

ANS: C Brachial plexus injuries (BPI) manifest by lack of movement of an arm, elbow, wrist, or hand. The arm is initially rested, then after 5 to 10 days, passive range of motion (ROM) is started. Parents are taught to do the passive ROM several times a day. This baby is too young to reach for toys and active movement is not encouraged. The baby does not need a sling. Microsurgical repair is indicated if repair is needed, but day 7 would be too early.

5. A student nurse is verbalizing disappointment in a new mother's seeming lack of interest in her newborn baby. The student complains to the registered nurse that the mother just wants to sleep and have someone else care for the infant. What response by the registered nurse is best? A. "Assess closely; we may need to call social work." B. "Don't judge other people until you have had a baby." C. "The mother may be completely exhausted from the childbirth experience." D. "We have to accept that everyone's experience is different."

ANS: C Each option has an element of an appropriate response to the student. A definitive lack of bonding may call for a social work consult. Nurses should not judge other people's responses. Every mother's experience is different. However, the best response is the one that gives the student definitive information that can clarify the situation. After a long and possibly difficult birth, the mother may be too exhausted and too overwhelmed to assume an active role in parenting at this point. The student should show acceptance, reinforce previously taught information, allow the mother rest, and assist with bonding as opportunities present themselves, praising the mother for her efforts.

16. A healthy term infant is being discharged at 48 hours of age. When should the nurse instruct the mother to follow up with a bilirubin assessment? A. Within 24 hours B. Within 24-48 hours C. Within 5 days D. In 1 week

ANS: C Healthy term infants discharged between 48 and 72 hours should receive follow-up and bilirubin assessment within 5 days.

22. A newborn has a blood glucose level of 188 mg/dL. What further assessment on this baby takes priority? A. Airway status B. Breathing status C. Circulatory status D. Skin status

ANS: C Hyperglycemia causes an osmotic diuresis and can lead to dehydration. The nurse needs to prioritize the assessment of fluid status over the other assessments.

24. A newborn baby has a calcium level of 7.1 mg/dL. What information should the nurse provide the parents? A. Low calcium can cause high blood sugars. B. Postterm babies are most at risk for this condition. C. The level will be rechecked at 72 hours. D. Your baby needs to have a magnesium level check.

ANS: C Hypocalcemia is a blood calcium level below 7.5 mg/dL. Calcium levels are lowest at 24-48 hours after birth; if levels remain low at 72 hours, the baby needs calcium supplements. The nurse should advise the parents that the level will be checked again at 72 hours. Hypocalcemia is often accompanied by hypoglycemia, but is not related to magnesium levels. Babies at risk for hypocalcemia include those whose mothers are diabetic, preterm newborns, and newborns with perinatal asphyxia.

11. The nurse is watching new parents suction their newborn. The baby begins gagging. What action should the nurse demonstrate to the parents? A. Pick the baby up and comfort her. B. Place the baby on her back. C. Turn the baby's head to the side. D. Wipe secretions out with a cloth.

ANS: C If the baby begins gagging or vomiting, the parents (or nurse) should position the infant's head to the side or downward to prevent aspiration. The other actions are not appropriate.

13. A new mother with a 6-hour-old infant calls the nursing station complaining that her baby is so cold he is shivering. What action by the nurse is most appropriate? A. Bring warm blankets to wrap the baby in. B. Encourage the mother to feed him a warmed bottle. C. Perform a thorough head-to-toe assessment. D. Set the room temperature higher.

ANS: C Infants are unable to shiver to produce heat. They produce heat through a mechanism called nonshivering thermogenesis. A report by the mother of an infant shivering requires a thorough investigation and assessment for problems such as seizures. The other actions are not needed

36. An infant was born with anencephaly and was taken immediately to the NICU. The parents are about to visit for the first time. What action by the nurse is most appropriate? A. Call the hospital chaplain to visit the parents. B. Obtain informed consent for emergency surgery. C. Prepare the parents for how the infant will look. D. Show the parents proper gowning and gloving.

ANS: C Infants born with anencephaly (incomplete closure of the anterior portion of the neural tube) are often missing parts of the brain, forehead, skull, and occiput. The nurse must be very sensitive in working with the parents of such children and needs to prepare the parents for how the child will look. Well-prepared parents have a better chance of being able to bond with their child. A visit from the chaplain may or may not be welcomed. Emergency surgery is not performed. Proper gowning and gloving are not needed unless the infant is in isolation.

23. A student nurse asks the newborn nursery nurse why so many babies prefer to be in a flexed position. What answer by the nurse is best? A. "Flexion keeps their limbs symmetrical." B. "It keeps their body temperature normal." C. "It's very familiar to them from being in utero." D. "They don't have the strength for extension."

ANS: C Many infants seek comfort and security by positioning themselves in flexion, the dominant position they were in while in utero. The other statements are inaccurate.

7. The perinatal nurse teaches the new mother and her family about appropriate infant care to prevent omphalitis. Information given would include which of the following instructions? A. Apply a mild soap and lotion to dry skin. B. Change diapers frequently following circumcision. C. Keep the base of the umbilical cord clean and dry. D. Take rectal temperatures twice a day for a week.

ANS: C Omphalitis is infection of the umbilical cord stump. The area around the base of the cord should be kept clean and dry. Cleaning the stump varies according to agency protocol. The other instructions are not related to omphalitis.

8. The pediatric nurse is providing care to an infant diagnosed with phenylketonuria. What education is vital for this nurse to provide the parents? A. Information available from the Centers for Disease Control and Prevention B. High-protein, low-carbohydrate diet for the life of the baby C. Special phenylalanine-free infant formula and diet restriction D. Very-low-protein diet supplemented with thiamine during childhood

ANS: C Phenylketonuria (PKU) is an autosomal recessive inborn error of metabolism. Individuals with PKU cannot convert phenylalanine to tyrosine, and if left untreated, the condition causes complications such as intellectual deficits. The person must follow a phenylalanine-free diet, which means eliminating protein, for the rest of his or her life. There are special formulas for infants with PKU. Information for the parents about informational resources is important, too, but the priority is on educating them regarding the diet. The child should not be on a high-protein diet. A low-protein diet supplemented with thiamine is the treatment for maple syrup urine disease, not for PKU.

1. The pediatric nurse prepares a newborn for phototherapy. The nurse explains to the parents that certain organs need to be protected during treatment. Which organs are these? A. Eyes and ears B. Eyes and hands C. Eyes and genitals D. Genitals and hands

ANS: C Phototherapy uses daylight and cool white, blue, or "special blue" fluorescent light tubes. These lights are the most effective form of phototherapy and are placed around and above the newborn. The eyes and genitals of the newborn are always covered to prevent tissue and retinal damage. The hands and ears of the newborn are not damaged by phototherapy

9. A preterm infant in the NICU is receiving oxygen, and the nurse notes that the oxygen saturation is 98%. Which action by the nurse is most appropriate? A. Call respiratory therapy to draw an arterial blood gas. B. Document the findings and continue to monitor. C. Lower the infant's oxygen concentration and reassess. D. See if the infant can tolerate more stimulation and activity

ANS: C Preterm infants receiving oxygen should only receive the amount of oxygen needed to maintain an oxygen saturation of greater than 92%, due to the risk of developing retinopathy of prematurity (ROP). Because this baby's O2 saturation is well above this reading, the nurse can try to reduce the flow and reassess. ABGs are not warranted. The nurse should document the findings, but further action is needed. Assessing activity tolerance is an ongoing assessment and is not related to preventing ROP

26. The nurse working in labor and delivery knows that which infant is at highest risk of having a long-bone fracture? A. Intrauterine growth restriction B. Mother with osteoporosis C. Multiples with one breech presentation D. Premature

ANS: C Risk factors for long-bone fractures include breech presentation, multiples, prematurity, and fetal osteoporosis. The premature baby has some risk, but not as much as multiple births with one breech presentation.

43. A perinatal clinic nurse is working with a pregnant woman who wishes a home birth. What information about newborn screening for metabolic disorders does the nurse provide? A. "A blood test will be performed within the first 2 weeks of your baby's life." B. "Newborns born at home do not need to be screened for metabolic diseases." C. "You will have to arrange screening before the end of the baby's first week of life." D. "Your birth attendant can draw blood from the umbilical cord for metabolic screening."

ANS: C Some newborn screening for metabolic disorders is required in all 50 states. For babies born at home, the person registering the baby's birth must make arrangements to have this testing done within the first week of the newborn's life.

44. The nurse is assessing an infant's extrusion reflex. To perform this correctly, what steps does the nurse take? A. Place a small object in the infant's hand. B. Stroke the side of the infant's cheek. C. Touch the tip of the infant's tongue. D. Turn the infant's head to one side.

ANS: C The extrusion reflex is elicited by touching the tip of the infant's tongue. The tongue should protrude outward. Palmar grasp is detected by placing a small object in the infant's hand. Stroking the side of the cheek should result in the rooting reflex. Turning the head and watching the position of the extremities is part of the tonic neck or fencing reflex.

31. A nurse observes a student nurse examining a newborn baby boy's scrotum and testicles. The student softly palpates the scrotum with all five digits of the dominant hand and states that there is only one testicle present. What action by the nurse is best? A. Ask the parents if this is a familial trait seen in male family members. B. Call the health-care provider and request a urology consult. C. Have the student repeat the exam using the proper technique. D. Perform the exam himself or herself and document the findings.

ANS: C The presence of only one descended testicle does call for a urology consultation. However, the student performed the examination incorrectly. The nurse should instruct the student on the proper technique (place the second finger at the posterior scrotal midline with the thumb on the anterior midline) and ask that the exam be repeated. The nurse is not helping the student by simply doing the exam. The situation of one testicle needs to be addressed whether or not this is seen frequently in this family, so asking the family about other males who had this condition is irrelevant.

45. The nurse holds an infant upright and allows his feet to brush the surface of the examination table. Which of the following is the normal reflex response to this stimulation? A. Draws legs up tight against the lower abdomen B. Extends legs straight against the pressure C. Makes stepping actions with both feet D. Toes curl in then fan outward symmetrically

ANS: C The stepping reflex occurs when the infant is held upright and his or her feet brush a horizontal surface distal to the feet. Drawing the legs up tight against the lower abdomen would be an abnormal response. Extending the legs against pressure is a positive magnet reflex. Curling the toes in, then fanning them outward, is a positive Babinski reflex

26. A nursing student is measuring a newborn baby's head circumference. Which action by the student demonstrates good understanding of this procedure? A. Measures three times, records the average B. Places tape measure at the hair line C. Records the largest of three measurements D. Uses two finger-breadths to estimate size

ANS: C The student should measure the infant's head three times and record the largest of the three measurements. The other actions are incorrect; the student should not use the average, the tape measure is placed above the eyebrows and pinna of the ear, and a tape measure is used, not the fingers.

10. A new nurse is suctioning a neonate. What action by the new nurse would cause the preceptor to intervene? A. Assesses the infant for secretions in the airway B. Places suction bulb into the baby's cheek C. Positions the suction bulb at the back of the throat D. Suctions the baby's mouth first, then the nares

ANS: C Touching the suction bulb to the roof of the infant's mouth or back of the throat can stimulate the gag reflex. The preceptor should intervene and correct this action. The other actions are appropriate.

11. A woman gave birth to an infant weighing 390 g. Which action by the NICU charge nurse is most appropriate? A. Begin the discharge planning process when the child is admitted. B. Consult social services to help make arrangements for home care. C. Consult the palliative care team and admit the infant for comfort care. D. Prepare for aggressive resuscitation and admission to the NICU.

ANS: C Very premature infants present moral and ethical dilemmas regarding their care. According to the International Liaison Committee on Resuscitation, infants born at less than 23 weeks' gestation or weighing less than 400 g are not candidates for resuscitation. The nurse should plan to admit this infant for comfort care only. The other options are not warranted.

25. A nurse takes a newborn's initial set of vital signs and records the following: Temperature: 97.9°F (36.6C), pulse: 198 beats/minute, respirations: 78 breaths/minute, blood pressure: 64/44 mm Hg. What does the nurse conclude about this infant? A. Hypotensive: needs IV fluid administration B. Hypothermic: needs to be put in an incubator C. Tachycardic: take pulse again when baby is not crying D. Tachypneic: suction if needed, administer oxygen per protocol

ANS: D A normal respiratory rate for an infant is 30-60 breaths/minute. This respiratory rate is too rapid, and the nurse needs to suction the infant if needed and provide oxygen per protocol. The blood pressure and temperature are normal. The heart rate is too fast, even for a crying baby.

29. A nurse is caring for a premature infant on oxygen. What action is critical for the infant's safety? A. Educate the parents to care for an infant on oxygen. B. Keep the infant in an incubator while on oxygen. C. Obtain daily chest x-rays to monitor lung maturity. D. Use the lowest amount of oxygen possible.

ANS: D Although oxygen therapy is often needed, it has complications, one of which is bronchopulmonary dysplasia (BPD). The use of supplemental oxygen results in lungs that fail to develop normal compliance. Preventative measures for BPD include using the lowest amount of oxygen needed to keep saturations in the desired range. If the child goes home on oxygen, the parents will need to be taught how to care for the baby. Lung maturity is assessed on the basis of function, not daily chest x-rays. The infant may need a warmer due to prematurity and inability to regulate temperature, but this is not a safety measure related to oxygen.

24. A nurse is beginning a newborn's physical assessment and notes that the infant is jumpy and seems irritable when being handled and when the nurse or parents speak. What action by the nurse is best? A. Ask the mother to attempt to breastfeed the infant. B. Conduct the assessment quickly then swaddle the baby. C. Increase the heat in the room so the baby won't get chilled. D. Postpone the assessment until the infant has calmed

ANS: D An infant who seems irritable and overreacts to voices, touch, or movement is displaying disorganized behavior. The nurse should postpone the physical examination until the infant has been calmed. To continue the assessment would risk increasing the baby's behavioral disorganization and would be disruptive for the infant. The other actions are not appropriate in this situation, although swaddling can help calm the baby, as can cuddling, rocking, and gentle holding.

4. The perinatal nurse explains the cardiopulmonary adaptations that occur in the neonate to a student nurse. Which of the following statements accurately describes the sequence of these changes? A. "As air enters the lungs, the PO2 rises in the alveoli, which causes pulmonary artery relaxation and results in an increase in pulmonary vascular resistance." B. "As the pulmonary vascular resistance increases, pulmonary blood flow increases, reaching 100% by the first 24 hours of life." C. "Decreased pulmonary blood volume contributes to the conversion from fetal to newborn circulation." D. "Once the pulmonary circulation has been functionally established, blood is distributed throughout the lungs."

ANS: D As air enters the lungs, the PO2 rises in the alveoli. This normal physiological response causes pulmonary artery relaxation and results in a decrease in pulmonary vascular resistance. As the pulmonary vascular resistance decreases, pulmonary blood flow increases, reaching 100% by the first 24 hours of life. The increased pulmonary blood volume contributes to the conversion from fetal to newborn circulation. Once the pulmonary circulation has been functionally established, blood is distributed throughout the lungs. The other explanations are inaccurate.

1. A woman gives birth to a healthy baby boy at 35 weeks' gestation. What factor regarding the development of the normal respiratory system should the nurse consider when performing an assessment of the neonate? A. As the fetus approaches term, secretion of intrapulmonary fluid increases. B. Lung expansion after birth suppresses the further release of surfactant. C. Surfactant increases alveolar surface tension, allowing re-expansion after exhalation. D. Surfactant production is sufficient to maintain alveolar stability by about 34 weeks.

ANS: D As the fetus approaches term, there is a decrease in the secretion of intrapulmonary fluid, which assists in reducing the pulmonary resistance to blood flow and facilitates the initiation of air breathing. Lung expansion after birth stimulates the release of surfactant—a slippery, detergent-like lipoprotein. Surfactant causes decreased surface tension within the alveoli, which allows for alveolar re-expansion following each exhalation. Under normal circumstances, by the 34th to 36th week of gestation, surfactant is produced in sufficient amounts to maintain alveolar stability.

47. The newborn nursery nurse knows that infant behavior is best assessed by which of the following? A. Ease of learning to nurse B. Length of sleeping periods C. Presence of reflex activity D. Response to stimulation

ANS: D Assessing a baby's response to stimulation is a vital part of a behavioral assessment. The other assessments are not really related, although a jittery, overstimulated baby who does not sleep well may need a quieter environment and more gentle handling.

19. A nursing student asks the registered nurse why babies get dehydrated so easily. What response by the nurse is most accurate? A. Babies are so tiny that a small water loss leads to big problems. B. Infants tend to lose more water through insensible losses. C. Because they don't drink much at a time, skipping a feeding is harmful. D. Infants' long intestines have more surface area from which to lose water.

ANS: D Babies' intestines are proportionally longer than adults'. This gives them more surface area from which to absorb nutrients, but also more surface area from which to lose water when they have diarrhea, leading to rapid dehydration.

3. A perinatal nurse has orders to administer betamethasone (Celestone) to the following women in preterm labor. For which patient should the nurse question this order? A. Emergency cesarean section B. Fetal cardiac abnormalities C. Maternal diabetes D. Severe preeclampsia/eclampsia

ANS: D Betamethasone is contraindicated in women in whom there is a medical indication for childbirth (e.g., severe preeclampsia/eclampsia, cord prolapse, chorioamnionitis, abruptio placentae) and in women with systemic fungal infection.

2. A nurse in the high-risk obstetrical unit monitors a student nurse preparing to give a patient a dose of betamethasone (Celestone). Which action by the student warrants intervention by the nurse? A. Assesses the patient's lung sounds prior to administration B. Draws up 12 mg in a syringe with a 20-gauge needle C. Gently shakes the medication before drawing it up D. Prepares to administer medication in the deltoid muscle

ANS: D Betamethasone should not be administered in the deltoid muscle, as it can cause local atrophy. It needs to be given in a larger muscle. The other actions are appropriate for this medication.

7. A nurse suspects that an infant in the intensive care unit has had intrauterine exposure to one of the TORCH infections. What finding is indicative of in utero exposure to a TORCH infection? A. Decreased IgA B. Decreased IgG C. Increased IgG D. Increased IgM

ANS: D Elevations in IgM can occur as a result of exposure to an intrauterine infection or one of the TORCH infections.

34. A nurse assessing an infant notes that the baby is jittery, has muscle twitches, and has jittery movement of the arms and legs. What action by the nurse is most appropriate? A. Call the physician and request muscle relaxants. B. Ensure the infant is kept warm in a quiet environment. C. Facilitate completion of either a CT or an MRI scan. D. Request laboratory work to detect substances of abuse.

ANS: D Hypertonia is characterized by muscle tremors, twitches, or jerkiness, and this finding is often associated with neonatal abstinence syndrome. The nurse should notify the health-care provider and request a drug screen. A warm, quiet environment may be best for this infant, but this action is not the priority. Muscle relaxants and scanning tests are not warranted.

10. A nurse explains to a student that which of the following is the mechanism by which circulation of oxygen is increased to the organs of a newborn? A. Deeper respirations B. Increased stroke volume C. Increased tidal volume D. Tachycardia

ANS: D In a newborn, ability to alter cardiac output is limited, and stroke volume cannot be improved. The physiological mechanism by which circulation of oxygenated blood to organs is improved in the newborn is tachycardia.

6. The perinatal nurse wants to contact the pediatrician about a heart murmur that was auscultated during a newborn assessment. During what time frame would hearing the murmur lead the nurse to contact the health-care provider? A. 8 to 12 hours B. 12 to 24 hours C. 24 to 48 hours D. 48 to 72 hours

ANS: D It is not uncommon to hear murmurs in infants less than 24 hours old. Hearing a murmur after 48 hours indicates a need for further investigation, and the health-care provider needs to be notified

17. A term infant is 22 hours old, has a total serum bilirubin level of 13 mg/dL, and has visible jaundice. What action by the nurse is most appropriate? A. Assure the parents that this is temporary. B. Document the findings in the infant's chart. C. Have the mother switch to bottle feeding. D. Review the chart for history of a traumatic birth

ANS: D Jaundice that appears within the first 24 hours of life is considered pathological. Causes can include events that lead to excessive breakdown of RBCs, leading to increased bilirubin levels, such as polycythemia, traumatic birth, infection, metabolic disorders, and Rh incompatibility. The diagnosis is made when total serum bilirubin levels rise higher than 12.9 mg/dL in term infants and 15 mg/dL in preterm infants. The nurse should review the chart for evidence of a traumatic birth. The other actions are not warranted.

40. New parents wish to include their extended family in welcoming their new baby. What suggestion does the nurse offer this couple? A. Avoid visitors for a month to prevent illness. B. Do not permit other individuals to feed the baby. C. Encourage visiting when the baby is sleeping. D. Welcome family in small groups for short visits.

ANS: D Nurses can foster attachment in several ways, including encouraging parents to invite siblings and other family members to visit for short periods of time to avoid tiring the mother and overstimulating the baby. Of course sick people should not visit. Others can be recruited to feed the baby, and often relatives and close friends desire to do so. If all the visiting takes place when the baby is sleeping, the baby and the visitors cannot get to know each other.

32. A premature infant in the NICU has a sudden increase in head circumference. Which drug does the nurse anticipate administering? A. Betamethasone (Celestone) B. Caffeine citrate (Cafcit) C. Morphine sulfate (Astromorph) D. Phenobarbital (Luminal Sodium)

ANS: D Premature infants are at risk of developing intraventricular hemorrhage and periventricular leukomalacia hemorrhage. A sign of this bleeding within the skull is increasing head circumference, which is measured frequently. The medication of choice is phenobarbital. Betamethasone is given to encourage fetal lung development. Morphine is a pain medication. Caffeine citrate is used for apnea of prematurity.

12. A neonate has difficulty maintaining a normal temperature. A student nurse prepares to place the infant under a radiant warmer. What action by the student leads the faculty member to intervene? A. Assesses the surrounding area for drafts B. Ensures the infant is dried off completely C. Observes the respiratory rate at the same time D. Wraps the baby in a warmed blanket

ANS: D Radiant heater units warm only the outer surface of objects in them, so it is counterproductive to dress the baby or cover the baby with blankets. The other actions are appropriate.

3. The pediatric nurse explains to the nursing student that respiratory distress syndrome results from a developmental lack of which substance? A. Calcium B. Lecithin C. Magnesium D. Surfactant

ANS: D Respiratory distress syndrome (RDS) is a developmental respiratory disorder that affects preterm newborns due to lack of lung surfactant. The other substances are not related to this disorder

20. A mother-baby nurse assesses newborns for their risk of developing hypoglycemia. Which infant would the nurse assess as being at highest risk? A. Asian ethnic background B. Delayed feedings after birth C. Infant with heat stress D. Maternal use of terbutaline (Brethine)

ANS: D Several risk factors for hypoglycemia exist, including pre- or post-maturity, intrauterine growth restriction, large or small for gestational age, asphyxia, difficult transition at birth, cold stress, maternal diabetes or preeclampsia-eclampsia, terbutaline use, infection, and congenital malformations.

17. A nurse has administered an analgesic to a premature infant in pain. What assessment would indicate to the nurse that the baby's pain is improving? A. Crunching the forehead B. Keeps eyes tightly closed C. Shallow respirations D. Sleeps after feeding

ANS: D Signs of pain in the infant include crunching the forehead, closing the eyes tightly, having shallow respirations, and experiencing altered sleep cycles. This baby is sleeping after a feeding, which is a normal sleep pattern, and thus indicates the pain is improving.

16. A nurse has been caring for a neonate with the nursing diagnosis of imbalanced body temperature. What assessment finding indicates to the nurse that goals for this diagnosis have been met? A. Hands and feet turn pink B. Infant stops shivering C. Pink and warm skin D. Temperature of 99.2°F (37.3°C)

ANS: D The normal temperature for a neonate is 97.7°-99.3° F (36.5°-37.4° C). A temperature within this range would indicate that goals for the nursing diagnosis have been met. The other assessments are not as accurate

4. The perinatal nurse teaches new parents that the best sleeping position for infants is which of the following? A. Prone B. Side-lying C. Side-lying with a blanket roll behind the infant's back D. Supine

ANS: D The nurse should teach the parents that all newborns should be placed on their backs (supine) for sleep by every caregiver for the first year of life.

30. A premature infant has not had a bowel movement, and the nurse assesses abdominal distention after the last feeding. What action by the nurse takes priority? A. Document the findings in the chart. B. Facilitate a bowel x-ray. C. Notify the health-care provider. D. Place the infant on NPO status.

ANS: D This baby has signs of necrotizing enterocolitis (NEC). When the nurse suspects this condition, the priority action is to stop all oral feedings. The other actions are appropriate, but do not take priority over placing the infant on NPO status.

20. A 2-hour-old infant has ruddy skin and delayed capillary refill. What laboratory value best correlates with this condition? A. Blood glucose is 38 mg/dL. B. Blood glucose is 65 mg/dL. C. Hematocrit is 42%. D. Hematocrit is 72%.

ANS: D This infant has some characteristic signs of polycythemia (ruddy skin, delayed capillary refill). The diagnosis of this disorder is based on a hematocrit of 65% or greater. A hematocrit of 42% is low. Blood glucose is not related.

13. A neonatal nurse is demonstrating the proper technique for assessing a newborn's pulse. What technique does the nurse demonstrate? A. Assess the point of maximal impulse, then auscultate the apical rate for 1 minute. B. Palpate the brachial pulse with two fingers for 30 seconds, and multiply by 2. C. Place the palm of the hand over the heart and palpate the apical pulse rate. D. Use two fingers and the thumb to feel the pulse at the base of the umbilical cord.

ANS: D To correctly take the pulse of a neonate, the nurse uses two fingers and the thumb to palpate the infant's pulse at the base of the umbilical cord.

15. An NICU nurse is caring for several infants who are being treated for hypothermia. Which baby can be dressed and taken out of the warmer? A. Skin pale but pink B. Sucks vigorously C. Temperature 97.4°F (36.3°C) D. Temperature 98.2°F (36.7°C)

ANS: D When the newborn is able to maintain her or his own temperature above 97.7°F (36.5°C), the nurse can switch the baby to air mode and dress him or her. The physical manifestations do not dictate the timing of this switch. The baby with a temperature of 97.4°F (36.3°C) is too cold to take out of the warmer.
