In addition to culturing the lesion, the nurse should anticipate that this infant will require which of the following tests on an urgent basis? correct answer LP- performed in all suspected cases of neonatal herpes simplex virus A 2 day old full term male w/ a hx of low apgar scores, poor urine output, and hypertonicity was noted to have 2 episodes of apnea accompanied by lip smacking and eye deviations. Episodes are most likely: correct answer Subtle seizures- most common type of seizures in premature infants Benign familiar seizures present similarly but w/o hx of low apgar scores

Neonatal myoclonus manifests as episodes of repetitive jerking or jitteriness that does not stop with passive restraint Tonic-clonic include stiffening and repetitive jerking A 2 day old is noted to have significant jaundice. His blood work shows decreased hgb, hyperbili, and a positive direct antigen test. These findings are most likely a result of? correct answer Immune-mediated hemolysis A 2 week old premie neonate has vesiculopapular lesions with an erythematous baise in her groin. Small white pustules can be seen on the lower abdomen. The most likely cause of this rash is correct answer Candida albicans- common in groin with satellite lesions extending beyond the groin A 3 day old infant born after induction at 41 weeks has a birthweight of 4.2kg. The infant has course facial features, a large anterior fontanel with a normal HC, an umbilical hernia, and a hx of poor feeding. The infant should be assessed for? correct answer Congenital hypothyroidism- signs are not always obvious at birth, often diagnosed during routine newborn screening. Other signs include thick skin, delayed bone age, poor perfusion, and hypothermia. A 3.2 kg, 37 week infant is admitted to the NICU because of resp distress. The infant was a c-sec for maternal HTN, APGARS were 6 and 8. On admission, the RR is 80-90 w/ moderate indrawing and occasional grunting. A chest radiograph shows increased vascular markings with expansion of the chest to the tenth rib. This infant most likely has: correct answer TTN- more common in late preterm and term infants born by c-sec. CXRs w/ over-expansion, haziness, increased vascular markings, and fluid in the fissure A 32-week preterm newborn born at a community facility has a HR of 130 bpm. The newborn is breathing spontaneously, although it has moderate retractions.

A 4000-g male infant has just been delivered via c sec due to fetal distress. The infant is born through thick meconium and requires ET suctioning. At the initial assessment, the infant's skin is noted to be leathery, cracked, and wrinkled. The infant's scrotum is noted to be pendulous with the testes descended. The nurse assessing this infant can anticipate that this infant is: correct answer Postterm A 41 wk baby is delivered by c sec for failure to progress. The baby is LGA with head, length, and weight all at the 95th percentile. On exam, the baby is centrally pink with no resp distress and has good tone. There is no caput or molding of the head noted. However, on palpation several soft spots that recoil with pressure are noted over the back of the head. Most likely explanation? correct answer Craniotabes- soft spots on the skull that collapse and recoil with pressure. Usually found in parietal or occipital region and though to result from bone reabsorption due to the pressure of the skull against the maternal pelvis A gestational age exam has just been performed on a newborn infant. The infant was noted to be in flexed position. The assessment shows that the square window angle is 0 degrees and the popliteal angle is 45 degrees, and the scarf sign eval shows increased resistance to crossing the midline. The infant's skin is noted to be cracking with no veins visible. Creases over the entire sole of the plantar surface are noted. Based on findings what's the gestational age? correct answer 40 weeks For a term infant, the square window angle would be 0 degrees, the popliteal would be 90 degrees, and in scarf sign testing, the elbow could not be pulled over the infant's body A mother reports that her week old daughter "has her own breast milk" On exam, the infant has enlarged breast tissue and milky secretions, but the chest otherwise appears normal. Advice to mom is based off the knowledge that: correct answer This is normal and will stop on it's own- influence of maternal

estrogen can cause engorgement with "witch's milk." Will disappear after a few months A newborn infant born at 37 weeks is in the 5th percentile for weight, length, and HC. The most likely explanation for this finding is: correct answer Intrauterine infection- symmetric IUGR begins early in gestation and is most often caused by intrauterine infection or genetic abnormalities. Chronic fetal distress is implicated as a cause of asymmetric growth restriction, resulting in a larger HC in comparison to length and weight. Maternal HTN can cause asymmetric IUGR A newborn infant presents with cyanosis. On exam the nurse hears a murmur at the left upper sternal border, but hears nothing else unusual. What cardiac defect is most likely responsible for these findings? correct answer TOF- the most common cyanotic heart defect. A grade 2-4 murmur is heard over the left upper sternal border ASD- splitting of the second heart sound, no cyanosis VSD- murmur at the left lower sternal border A newborn is cyanotic, is grunting, and has a barrel chest and scaphoid abdomen, Upon auscultation the nurse hears bowel sounds in the L side of its chest. Breath sounds are diminished. Most likely cause? correct answer Congenital diaphragmatic hernia A newborn presents with FTT, liver failure, coppery brown skin rash, and purulent nasal discharge. The mother should be tested for? correct answer Syphilis A newborn's mother asks why the nurse is performing a gestational age assessment when she had ultrasonography to determine her due date. The best

secretions until approximately 2 weeks before the onset of delivery, term or preterm. A physical assessment performed on a newborn infant notes that the skin of the infant is wrinkling, the areolae are raised with 10-mm buds, and the pinna springs back from being folded. Based on these physical assessment findings, this infant is considered to be correct answer Term- beyond 38 weeks, subcutaneous tissue decreases which causes the skin to wrinkle, breast tissue nodule measures up to 10mm, cartilage in pinna *very postterm and extremely preterm are not gestational categories A systematic approach to the physical exam of a newborn should be performed: correct answer between 12-18 hours of life (after successfully transitioning-- at birth may be too soon) A term infant delivered vaginally had APGAR scores of 9 at 1 min and 9 at 5 mins. The maternal hx identifies that mom is hep B surface antigen +. The plan of care for this infant should include which one of the following options? correct answer Administer hep B immune globulin and hep B vaccine within 12 hours after birth. Term infant with negative mother should be given hep b vaxx at time of discharge A term infant if now 24 hours old and rooming in w/ mom. The infant was a c-sec due to maternal arrest of labor. Apgars of 7 and 8. Membranes ruptured 12 hours before delivery and were mec stained. Prenatal group B step screen at 36 weeks (-). Maternal T before delivery was 100.2. Assessment reveals color slightly pale, decreased peripheral pulses and perfusion in lower extremities, difficulty getting baby to latch, slight lethargy, and RR 80 w/ no grunting, flaring, or retractions. Interventions? correct answer Notify the pediatric provider and transfer infant to

the special care nursery for obs under a radiant warmer with the poss dx of coarction of the aorta -COA has the classic findings of decreased perfusion and pulses in the lower extremities. Can develop temp instabilities and poor feeding. VHD should be suspected when infants present with an increase in RR in the absence of any other resp distress and cyanosis A term infant is born to a mother with a history of cocaine use in pregnancy. The mother is concerned about the effects of cocaine on her baby. The nurse's response should be based on the knowledge that intrauterine cocaine exposure increases the risk of: correct answer perinatal infection and respiratory distress syndrome A term infant is born via normal spontaneous vaginal deliver. The infant is noted to be cyanotic when quiet but pinks up when crying. The most likely dx? correct answer Choanal atresia A term infant is noted to have low-set ears, a short neck with excessive skin, brushfield spots, a large tongue, and simian creases. This infant is at increased risk of correct answer Duodenal atresia Heart defects seen in Tri21 inckude cardial cushion defects, VSD, PDA, ASD, and TOF. Infants at increased risk of renal anomalies A term infant presents with tachypnea and increased WOB. The infant's O2 sat is 78%-80% despite being given 100% O2. Congenital heart disease is suspected. Which of the following defects is most likely to cause these symptoms? correct answer Transposition of the great vessels occurs when the aorta arises from the RV and the pulmonary artery rises from the LV. Marked cyanosis is a presenting feature because the aorta carries deoxygenated blood from the RV to the systemic circulation

Breath sounds can be heard over both the lung fields and the stomach. The stomach is distended. Most likely, the ETT is: correct answer In the esophagus During a routine assessment after a spontaneous vaginal birth at term gestation, the neonate is pink when crying but demonstrates central cyanosis when quiet. Breath sounds are equal w/ no tachypnea. Most likely cause? correct answer Bilateral choanal atresia *neonates are obligate nose breathers

Elevated maternal serum a-fetoprotein is associated with: correct answer neural tube defects- MSAFP is a protein made by the fetal liver. High levels may indicate neural tube defects or ventral abdominal wall defects, esophageal and duodenal atresia, and some renal or urinary tract anomalies. Low levels occur in some case of down syndrome Erythema toxicum correct answer A pustular rash on an erythematous base.

The rash consists of a mix of vesicles, pustules, and brown macules. The infant is afebrile and feeding well. The rash most likely

represents: correct answer Transient neonatal pustular melanosis- pustular melanosis is more common in infants with pigmented skin. The benign rash consists of a mixture of vesicles and pustules and pigmented macules. The vesicles and pustules resolve quickly, however the macules may remain for several months. The nurse is performing a gestational age assessment on a premature infant. Observations will likely include which of the following? correct answer Preterm infants have smooth plantar surfaces, which develop creases as the mature, and large amounts of lanugo over the shoulders and back, which will eventually slough off into the amniotic fluid as they get closer to term. Vernix covers preterm fetuses, but sloughs off into the amniotic fluid as the fetus develops, so that by term it is only left in the skin folds like the groin and axilla.
