18
Q

What nursing considerations should be in place for the postterm neonate?

A
  • Intrapartal Hypoxia: decreased placental function (diminished fetal reserves)
  • Hypothermia/Cold Stress: Brown fat stores are depleted as a result of decreased placental function and needing to use it for enegy
  • Hypoglycemia: Depleted glycogen stores
19
Q

What are the priorities of care for preterm and postterm neonates?

A
  • Thermoneutral environment
  • Vital sign stability
  • Fluid and nutrient intake
  • Infection control
  • Behavioral state: environmental modifications to support need for rest, quiet
  • Parental/Neonatal attachment and bonding: kangaroo care
20
Q

How is pathological jaundice defined?

A

Any clinically evident jaundice prior to 24 hours of age is considered pathologic. Bilirubin levels rising at greater than 5mg/dL per 24 hours also suggests pathology. Any jaundice persisting greater than 6 days in a term infant OR greater than 14 days in a preterm infant is considered pathologic.

21
Q

What are the etiologies of pathological jaundice?

A
  • Rh or ABO incompatibility: Hemolytic disease of the neonate
  • Prematurity
  • Cephalohematoma (birth trauma)
  • Nutritional/Fluid Deficits
  • Sepsis
22
Q

How does pathological jaundice present itself in the neonate? (neonatal morbidity)

A
  • Lethargy
  • Poor feeding: excessive weight loss, diminished output
  • Kernicterus: encephalopathy caused by deposition of bilirubin in brain cells, potential for neurologic compromise of varying degrees
23
Q

What nursing considerations should be in place for a neonate with pathological jaundice?

A
  • Identify any risk factors: maternal blood type and Rh, antepartal RhoGAM if indicated, perinatal course, gestational age
  • Determine neonate’s blood type, Rh, Direct Coombs
  • Draw bilirubin levels per protocol/order
  • Initiate phototherapy protocol per order
24
Q

Discuss the conjugation of bilirubin

A

Indirect Bilirubin: Unconjugated bilirubin is fat soluable. It attaches to binding sites on plasma albumin and is transported to the liver. It is converted to conjugated bilirubin (glurcuronyl transferase).

Direct Bilirubin: Conjugated bilirubin is water soluable. It is excreted VIA stool and urine.

The indirect bilirubin level plus the direct bilirubin level equals the total bilirubin level

25
Q

Discuss phototherapy treatment for jaundiced neonates

A

The neonate is exposed to high-intensity fluorescent light which facilitates the excretion of unconjugated bilirubin and bypasses the hepatic conjugation.

Nursing diagnoses: Fluid Volume Deficit R/T insensible water loss and inadequate oral intake, Impaired Skin Integrity R/T frequent loose stools, Risk for Altered Parenting

26
Q

Discuss the reasons for pathological jaundice in the fetus (prenatal)

A
  • Erythroblastosis Fetalis: Rh incompatibility only. Transplacental passage of maternal antibodies leads to hemolysis of fetal RBCs
  • Hydrops Fetalis: Most severe form of erythroblastosis fetalis. Severe anemia and multiorgan system failure (intrauterine blood transfusion is treatment)
27
Q

Discuss sepsis neonatorum

A

Systemic infection during the neonatal period (6 weeks after birth). Early onset sepsis is acquired perinatally, through prolonged labor, chorioamnioitis, or PROM; it is evident through the first hours after birth and has a high mortality rate. Late onset sepsis develops during the first week of the neonate’s life and is more specific and localized, therefore, it has a lower mortality rate than early onset sepsis.

28
Q

What is proper nursing managment of sepsis neonatorum?

A
  • Know that early signs and symptoms are often subtle: temperature instability (generally hypothermic)
  • Impaired respiratory function
  • Cardiovascular indicators: tachycardia/color changes
  • Gastrointestinal Indicators: feeding intolerance leads to hypoglycemia
  • Neurological indicators: lethargy/irritability/high-pitched cry
29
Q

Discuss Neonatal Abstinence Syndrome (NAS)

A
  • Prenatal chemical exposure: opiates, tranquilizers, sedatives, ETOH
  • Onset for ETOH is 3-12 hours
  • Onset for opiates is 48-72 hours (often after discharge)
  • Observable indicators: tremors/hypertonicity, irritability/high-pitched cry, excessive sucking with uncoordinated suck/swallow reflexes
30
Q

What are the nursing responsbilities associated with neonatal abstinence syndrome (NAS)?

A
  • Collect first urine for chemical dependency
  • Administer medical withdrawal regimen: NAS scoring per protocol
  • Feeding: minimize distractions/ guard against aspiration
  • Environment: containment/controlled stimulation
  • Parent/child attachment
31
Q

Discuss Phenylketonuria (DKU)

A

CNS damage due to toxic level of phenylalanine and a deficiency of phenylalanine hydroxylase which leads to autosomal recessive disorder. Nursing responsiblities include facilitating the mandated NYS screening (make sure screening is done before discharge). Management for PKU is lifelong low-phenylalnine diet and low protein foods.

32
Q

Discuss Trisomy 21

A

Down syndrome. Each cell contains an “extra” chromosome #21 that causes delayed attainment of developmental milestones. The characteristic physical findings are small low-set ears, hypotonia, palmar crease (just one), flattened facial profile. Diagnoses are VIA karyotyping.

33
Q

Define intrauterine growth restriction (IUGR)

A

Impaired fetal growth due to any etiology

34
Q

Define macrosomia

A

Large fetal body size and weight

35
Q

Define polycythemia

A

Abnormal increase in the number of red blood cells in circulation

36
Q

Define tansient tachpnea of the neonate (TTN)

A

Tachypnea clinically evident by six hours of age, caused by excessive fluid or mucous in the lungs

37
Q

Define meconium aspiration syndrome (MAS)

A

Inhalation of meconium or meconium-stained fluid, characterized by respiratory distress

38
Q

Define respiratory distress syndrome (RDS)

A

Impaired ventilation at the alveolar level (membrane disease)

39
Q

Define hyperbilirubinemia

A

Excessive bilirubin in the blood, indicative of hemolytric process

40
Q

Define Kernicterus

A

Encephalopathy caused by deposition of unconjugated bilirubin in brain cells

41
Q

Define Erythroblastosis Fetalis

A

Hemolytric disease of the neonate characterized by anemia, jaundice, hepatomegaly, and generalized edema

42
Q

Define sepsis neonatorum

A

Generalized infection that spreads rapidly through the bloodstream during the neonatal period (first 28 days of life)

43
Q

Identify maternal data indicative of the need for a neonatal toxicology screen

A

Reported substance use/abuse an/or absence of prenatal care
