NLE Newborn & Neonatal Nursing — High-Risk Newborn & Neonatal DisordersRevision Notes

Exam Tips

• NLE loves to ask: 'A preterm infant is born at 32 weeks. Which finding requires IMMEDIATE nursing action?' — Always prioritize airway/breathing first, then temperature.
• Remember the weight thresholds as a ladder: 2,500 (LBW) → 1,500 (VLBW) → 1,000 (ELBW).
• If the question mentions abdominal distension + bloody stools in a preterm infant → think NEC → action = NPO + notify physician.
• KMC is a frequent Philippine NLE topic — know its benefits and that it can be done even with a stable infant on supplemental oxygen.
• Cluster care = group interventions to allow rest → reduces oxygen consumption → prioritize this in care planning questions.

Key Points

• Preterm infant = born BEFORE 37 completed weeks of gestation (not 37 weeks and 0 days — must be LESS than 37 weeks).
• Weight classifications (independent of gestational age): LBW = under 2,500 g; VLBW = under 1,500 g; ELBW = under 1,000 g.
• A small-for-gestational-age (SGA) infant has a weight below the 10th percentile for gestational age — this is different from LBW; an SGA infant may be term or preterm.
• A large-for-gestational-age (LGA) infant weighs above the 90th percentile — common in infants of diabetic mothers.
• Prematurity affects ALL organ systems because maturation is incomplete: respiratory (surfactant deficiency → RDS), thermoregulation (minimal brown fat), GI (weak suck-swallow → gavage feeding; risk of necrotizing enterocolitis/NEC), neurologic (fragile germinal-matrix → intraventricular hemorrhage/IVH), immune (high infection risk), eyes (retinopathy of prematurity/ROP from oxygen exposure), and hepatic (hyperbilirubinemia, hypoglycemia).
• Apnea of prematurity = respiratory pause OVER 20 seconds, OR any pause with bradycardia or cyanosis — requires stimulation (tactile first) and possible caffeine citrate therapy.
• Necrotizing enterocolitis (NEC) signs: abdominal distension, bloody stools, feeding intolerance, and absent bowel sounds — a neonatal surgical emergency.
• Neutral thermal environment (NTE) is the temperature range at which the infant expends the least energy to maintain normal body temperature; maintained via incubator or radiant warmer.
• Kangaroo Mother Care (KMC) / skin-to-skin care is strongly promoted by Philippine DOH as evidence-based care for preterm and LBW infants — it supports thermoregulation, oxygenation, breastfeeding, and mother-infant bonding.
• Nursing priority cluster: WARM → OXYGENATE → FEED → PROTECT → MONITOR (glucose, weight, I&O, head circumference).
• Cluster care: group nursing interventions together and allow rest periods between to minimize oxygen consumption and energy expenditure in the preterm infant.
• Retinopathy of prematurity (ROP): immature retinal vessels are damaged by excessive oxygen. Titrate O2 to maintain SpO2 within ordered range (typically 90–95% for preterm infants); avoid hyperoxia.

Section Title

Prematurity and Low Birth Weight (LBW)

Common Mistakes

• Confusing preterm (gestational age criterion) with LBW (weight criterion) — a term infant can be LBW if SGA, and a preterm infant may not always be LBW.
• Forgetting that apnea requires a pause OVER 20 seconds or any pause with bradycardia/cyanosis — a 15-second pause without bradycardia is NOT apnea of prematurity.
• Using too high an oxygen concentration in preterm infants without titrating — this causes ROP.
• Forgetting that NEC is a contraindication to feeding — answer choices about continuing feeds in a suspected NEC case are WRONG.
• Assuming all small newborns are preterm — SGA term infants have different care priorities.

Exam Tips

• If the question asks about PREVENTION of RDS in a mother at 30 weeks about to deliver → answer = administer betamethasone to the MOTHER.
• If the question asks about TREATMENT of RDS in the neonate → answer = exogenous surfactant (beractant/poractant alfa) instilled into ET tube.
• TTN vs RDS: TTN = C-section, term baby, mild, self-limiting in 72 hrs. RDS = preterm, surfactant deficiency, requires surfactant therapy.
• The 3 cardinal signs of RDS to memorize: GRUNTING + NASAL FLARING + RETRACTIONS (intercostal, subcostal, sternal).
• For meconium aspiration: if the infant is vigorous (crying, good tone, HR>100), do NOT intubate for routine suctioning — just provide supportive care.

Key Points

• RDS = surfactant deficiency → alveolar collapse (atelectasis) → hypoxemia → respiratory failure. Primary disease of prematurity; surfactant production is adequate by about 34–35 weeks.
• Additional risk factors for RDS: maternal diabetes mellitus (insulin delays surfactant production), elective cesarean section without labor (labor stimulates surfactant release), male sex, second-born twin.
• Classic signs appearing within HOURS of birth: tachypnea (respiratory rate >60/min), expiratory GRUNTING (auto-PEEP mechanism to keep alveoli open), nasal flaring, intercostal/subcostal/sternal retractions, central cyanosis, and see-saw (paradoxical/seesaw) breathing where the chest goes in and abdomen goes out.
• Chest X-ray finding: diffuse 'ground-glass' reticulogranular (granular) pattern with air bronchograms.
• Treatment cornerstone: EXOGENOUS SURFACTANT instilled directly into the ET tube — drugs include beractant (Survanta), poractant alfa (Curosurf), and calfactant (Infasurf). Effect is rapid improvement in lung compliance.
• Respiratory support: CPAP (continuous positive airway pressure) as first-line support for mild-moderate RDS, escalating to mechanical ventilation as needed.
• Oxygen titration: target SpO2 as ordered (usually 90–95% for preterm to prevent ROP); NEVER give 100% O2 to preterm infants routinely.
• ANTENATAL PREVENTION: maternal corticosteroids — betamethasone (preferred) or dexamethasone — given 24–48 hours before anticipated preterm delivery to accelerate fetal lung maturity by stimulating surfactant production. This is a HIGH-YIELD NLE point.
• Transient Tachypnea of the Newborn (TTN): caused by retained fetal lung fluid, most common after elective cesarean section (no labor = less thoracic squeeze). Presents as tachypnea and mild respiratory distress; resolves within 24–72 hours with supportive care.
• Meconium Aspiration Syndrome (MAS): meconium-stained amniotic fluid (MSAF) is aspirated, causing mechanical obstruction and chemical pneumonitis. Seen in post-term (>42 weeks) and stressed/hypoxic infants. Management: suction if the infant is NOT vigorous (no tone, no breathing, HR<100); intubation and tracheal suctioning if indicated.
• Persistent Pulmonary Hypertension of the Newborn (PPHN): failure of the normal drop in pulmonary vascular resistance after birth → right-to-left shunting through fetal channels → severe cyanosis. Requires high-frequency ventilation and inhaled nitric oxide.

Section Title

Respiratory Distress Syndrome (RDS) and Related Respiratory Conditions

Common Mistakes

• Confusing TTN (term/near-term, C-section, resolves in 24–72 hrs) with RDS (preterm, surfactant deficiency, more severe).
• Forgetting that grunting is an infant's self-protective mechanism — it helps keep alveoli open, so do NOT suppress it without addressing the underlying cause.
• Thinking surfactant is given IM or IV — it is instilled INTRATRACHEALLY through the ET tube.
• Forgetting that betamethasone is given to the MOTHER, not the infant.
• Applying 100% oxygen to a preterm infant — always titrate to the ordered SpO2 range to prevent ROP.

Formulas

Exam Tips

• MEMORIZE THIS: Physiologic = AFTER 24 hours. Pathologic = WITHIN 24 hours (day 1). This distinction appears in almost every NLE exam.
• Phototherapy nursing care priority answer: 'Cover the eyes with opaque patches' — this is the most tested single phototherapy nursing action.
• If the question asks when to turn off the phototherapy light → answer: when drawing blood for serum bilirubin.
• For exchange transfusion monitoring: watch for HYPOCALCEMIA (signs: jitteriness, prolonged QT) — the citrate in stored blood chelates calcium.
• Rho(D) immune globulin timing: given to the MOTHER within 72 HOURS of delivery — not to the baby.
• Kernicterus early signs: lethargy + poor feeding + HIGH-PITCHED cry — these 3 together in a jaundiced newborn = emergency.

Key Points

• Bilirubin is produced from the breakdown of RBCs (heme → biliverdin → unconjugated/indirect bilirubin). The immature neonatal liver conjugates it slowly, and the high RBC load in newborns produces a physiologic bilirubin load.
• JAUNDICE BECOMES VISIBLE (detected by blanching the skin) at a total serum bilirubin (TSB) of approximately 5 mg/dL.
• Jaundice progresses CEPHALOCAUDALLY: face first → trunk → extremities → palms and soles (most severe). The Kramer's rule helps estimate bilirubin level by zone of jaundice.
• PHYSIOLOGIC JAUNDICE: appears AFTER the first 24 hours of life (typically day 2–3), peaks day 3–5 in term infants, and resolves by 1 week (term) or 2 weeks (preterm). It is benign and requires only monitoring and adequate feeding.
• PATHOLOGIC JAUNDICE: appears WITHIN THE FIRST 24 HOURS of life. Any jaundice in the first 24 hours is PATHOLOGIC until proven otherwise. Also pathologic: rapidly rising bilirubin (>5 mg/dL/day), very high levels, or jaundice persisting beyond 2 weeks (term) or 3 weeks (preterm).
• Common causes of pathologic jaundice: Rh incompatibility (erythroblastosis fetalis), ABO incompatibility (most common), and neonatal sepsis.
• CONJUGATED (DIRECT) BILIRUBIN >2 mg/dL (or >20% of total) is ALWAYS PATHOLOGIC and indicates hepatic or biliary pathology (biliary atresia, neonatal hepatitis). Phototherapy does NOT treat conjugated hyperbilirubinemia.
• KERNICTERUS (bilirubin encephalopathy): UNCONJUGATED (indirect) bilirubin is fat-soluble and crosses the blood-brain barrier, depositing in the basal ganglia. Signs: lethargy → poor feeding → high-pitched cry → hypertonia → opisthotonus → permanent neurologic damage (intellectual disability, cerebral palsy, hearing loss). Risk rises toward ~20–25 mg/dL in TERM infants (much lower thresholds for preterm/sick infants).
• Treatment thresholds are determined by the BHUTANI HOUR-SPECIFIC NOMOGRAM (plots TSB against postnatal age in hours) — NOT a single fixed number. This is the current standard.
• PHOTOTHERAPY: converts unconjugated bilirubin in the skin to water-soluble photoisomers (lumirubin) that can be excreted in urine and bile WITHOUT conjugation.
• Phototherapy nursing care (HIGH-YIELD): (1) Expose MAXIMUM SKIN SURFACE — undress the infant except for a small diaper cover over the genitals. (2) Cover the EYES with opaque patches (phototherapy masks) — prevents retinal damage. (3) TURN OFF the lights when drawing blood for serum bilirubin (light degrades bilirubin in the sample and gives a false-low result). (4) Monitor TEMPERATURE — radiant warmer can cause hyperthermia. (5) Maintain HYDRATION and FREQUENT FEEDING — loose, watery green stools are expected (accelerated bilirubin excretion). (6) REPOSITION frequently (supine, lateral, prone if monitored) to expose different skin surfaces. (7) Ensure the light is at the correct distance per manufacturer specifications.
• EXCHANGE TRANSFUSION: used for severe hyperbilirubinemia not controlled by intensive phototherapy, approaching the exchange threshold (often cited ~20–25 mg/dL in term infants). Removes bilirubin-loaded blood and antibody-coated RBCs; replaces with donor blood. Most common complication: hypocalcemia.
• BREASTFEEDING (EARLY) JAUNDICE: appears in first days due to INSUFFICIENT MILK INTAKE → less stool → less bilirubin excretion. Management: increase breastfeeding frequency (8–12 times/day), assess latch and supply.
• BREAST-MILK (LATE) JAUNDICE: appears after day 4–7, peaks around week 2, caused by a substance in mature breast milk that inhibits conjugation. Generally benign; do NOT routinely recommend stopping breastfeeding.
• PREVENTION of Rh disease in FUTURE pregnancies: administer Rho(D) immune globulin (RhoGAM) to an Rh-negative mother who delivers an Rh-positive infant, within 72 hours of delivery.

Section Title

Hyperbilirubinemia and Neonatal Jaundice

Common Mistakes

• Forgetting to COVER THE EYES during phototherapy — this is almost always an answer option on NLE.
• Leaving the phototherapy lights ON when drawing blood for serum bilirubin — this causes a false low reading.
• Recommending the mother to STOP breastfeeding for breast-milk jaundice — current recommendation is to CONTINUE breastfeeding; temporary interruption is only considered in severe cases.
• Confusing physiologic (after 24 hrs) with pathologic jaundice (within 24 hrs) — a very frequent NLE question stem.
• Thinking phototherapy cures jaundice instantly — bilirubin levels are rechecked 4–12 hours after initiating phototherapy.
• Using a fixed cutoff of 20 mg/dL as the treatment threshold for ALL infants — the Bhutani nomogram must be used; thresholds are LOWER for preterm and sick infants.
• Forgetting that conjugated bilirubin >2 mg/dL is ALWAYS pathologic — it is never physiologic.

Exam Tips

• Ampicillin + Gentamicin = the standard empiric regimen for neonatal sepsis. Memorize this combination.
• NLE question stem: 'A term newborn on day 2 has a temperature of 35.8°C, poor feeding, and is lethargic' → Think sepsis → first action: obtain blood culture, THEN notify physician and prepare antibiotics.
• GBS is the #1 organism in early-onset neonatal sepsis. Prevention = maternal penicillin/ampicillin during labor.
• The single most effective nursing measure to prevent late-onset NICU sepsis = HAND HYGIENE. This is always a correct answer option.
• Neonatal meningitis complication sign: BULGING FONTANELLE + high-pitched cry → urgently report to physician.

Key Points

• Neonatal sepsis = a systemic infection (bacteremia/septicemia) in the first 28 days of life. Dangerous because signs are SUBTLE and NONSPECIFIC — 'the baby just isn't doing right.'
• EARLY-ONSET SEPSIS (EOS): within 72 hours of birth (some sources: within 7 days). Acquired vertically from the birth canal (maternal source). Predominant organisms: Group B Streptococcus (GBS) — the #1 cause — and Escherichia coli. Risk factors: prolonged rupture of membranes (PROM >18 hrs), maternal fever/chorioamnionitis, maternal GBS colonization (vaginal-rectal swab at 35–37 weeks gestation), prematurity, low birth weight.
• LATE-ONSET SEPSIS (LOS): after 72 hours of birth (some sources: after 7 days). Acquired from the environment (nosocomial). Common organisms: coagulase-negative Staphylococcus (CONS), Staphylococcus aureus, Gram-negative bacilli, Candida. Risk factors: central venous catheters, prolonged hospitalization, invasive procedures.
• CARDINAL RULE: in neonates, TEMPERATURE INSTABILITY is more common than fever. Newborns often present with HYPOTHERMIA (temperature <36.5°C) rather than fever (>38°C). A temperature change in either direction in a newborn is a RED FLAG for sepsis.
• Clinical signs of neonatal sepsis (the 'sepsis triad' plus more): Temperature instability (hypothermia OR fever), Poor feeding / feeding intolerance, Lethargy or irritability (subtle behavior change), Tachypnea, apnea, or respiratory distress, Tachycardia or bradycardia, Hypotonia (floppy infant), Hypoglycemia or hyperglycemia, Jaundice, Mottling, pallor, or poor peripheral perfusion (delayed capillary refill >3 seconds), Bulging fontanelle if meningitis develops.
• DIAGNOSIS: Blood culture (gold standard — obtain BEFORE starting antibiotics), CBC with differential (neutropenia or left shift: bands >20%), C-reactive protein (CRP), blood glucose, lumbar puncture (CSF culture) if meningitis is suspected, urine culture in late-onset sepsis.
• MANAGEMENT — the '1-hour bundle' principle: (1) OBTAIN CULTURES FIRST (blood culture, and indicated CSF/urine) → (2) START EMPIRIC BROAD-SPECTRUM IV ANTIBIOTICS IMMEDIATELY — do NOT wait for culture results. Standard empiric regimen: AMPICILLIN + GENTAMICIN (covers GBS, E. coli, and Listeria). If Staph or Gram-negative predominance suspected in LOS, add or switch accordingly. (3) SUPPORTIVE CARE: oxygenation/ventilation, thermoregulation (incubator), IV fluids and glucose, monitoring.
• Antibiotic de-escalation: narrow antibiotics once culture and sensitivity results are known (48–72 hrs).
• PREVENTION: (1) Intrapartum antibiotic prophylaxis (IAP) — penicillin G (preferred) or ampicillin IV during labor for GBS-positive mothers or those with risk factors. (2) Strict HAND HYGIENE — the single most effective measure to prevent nosocomial (late-onset) sepsis in the NICU. (3) Minimize invasive devices and procedures.
• Meningitis in neonates: a complication of bacteremia; signs include bulging fontanelle, high-pitched cry, seizures, and neck stiffness (less reliable in neonates).

Section Title

Neonatal Sepsis

Common Mistakes

• Starting antibiotics BEFORE drawing blood cultures — always culture first, then treat.
• Expecting FEVER in neonatal sepsis — HYPOTHERMIA is more common in newborns; both temperature extremes are concerning.
• Using only ONE antibiotic empirically — the standard empiric regimen is ampicillin PLUS gentamicin (combination coverage).
• Waiting for sepsis signs to be obvious before acting — subtle behavioral changes (poor feeding, lethargy) ARE early sepsis signs; report and act promptly.
• Forgetting that hand hygiene is the #1 prevention for nosocomial (late-onset) sepsis in the NICU.

Exam Tips

• TEF: '3 Cs' = Coughing, Choking, Cyanosis with feeding → NPO + suction + elevate head → priority intervention.
• Diaphragmatic hernia: NO BAG-MASK VENTILATION → intubate + OG tube decompression. This is a frequently tested critical nursing action.
• Myelomeningocele: PRONE position + sterile moist dressing + measure head circumference daily = the 3 post-birth priorities.
• Post-op cleft lip: no prone, use elbow restraints, protect suture line — these 3 actions are commonly tested as a group.
• For any abdominal wall defect (gastroschisis/omphalocele): cover with saline-moist sterile gauze + plastic wrap → NPO → IV fluids → surgery.

Key Points

• CLEFT LIP AND PALATE: A failure of fusion of the facial structures. Cleft lip (±palate) is the most visible; cleft palate alone affects feeding and speech differently. Main problems: inability to create suction/negative pressure for feeding → feeding difficulty and aspiration risk. Management: (1) Use special feeding devices (wide-based, soft, squeezable bottles — Haberman feeder, pigeon nipple, or Mead Johnson cleft palate feeder); (2) Feed upright (45–90 degrees) to prevent aspiration; (3) Burp frequently (after every 15–30 mL) due to excessive air swallowing; (4) Support bonding (cover/show parent how to hold and feed; reassure about surgical repair outcomes). Surgical repair: cleft lip (cheiloplasty) around 3–6 months; cleft palate (palatoplasty) around 6–18 months. POST-OP CLEFT LIP: PROTECT THE SUTURE LINE: NO prone positioning, elbow restraints (to prevent infant from touching incision), avoid tension/crying, clean suture line as ordered.
• ESOPHAGEAL ATRESIA (EA) AND TRACHEOESOPHAGEAL FISTULA (TEF): The esophagus ends in a blind pouch (EA) with an abnormal connection to the trachea (TEF). Most common type (Type C / Type III): proximal esophageal atresia + distal TEF. The '3 Cs' of TEF: COUGHING, CHOKING, CYANOSIS with feeding. Other signs: excessive drooling and frothy secretions, inability to pass a nasogastric tube (tube coils back), aspiration pneumonia risk, polyhydramnios in utero (fetus cannot swallow amniotic fluid). NURSING PRIORITY: (1) Keep NPO — absolutely nothing by mouth; (2) Continuous LOW-WALL suction of the blind pouch to prevent aspiration of secretions; (3) Elevate the HEAD (30–45 degrees) to prevent reflux and aspiration; (4) Prepare for surgical repair; (5) Keep warm and monitor oxygen saturation.
• DIAPHRAGMATIC HERNIA (CDH): Abdominal organs (bowel, stomach, spleen) herniate into the chest cavity through a defect in the diaphragm (usually left-sided Bochdalek hernia). This compresses the lung on the affected side, causing pulmonary hypoplasia and severe respiratory distress. Classic signs: RESPIRATORY DISTRESS at birth, SCAPHOID (boat-shaped, sunken) ABDOMEN (bowel is in the chest), barrel-shaped chest, BOWEL SOUNDS HEARD IN THE CHEST (auscultation), shifted heart sounds (mediastinum shifted to the opposite side). CRITICAL NURSING ACTION: DO NOT use BAG-MASK VENTILATION (positive pressure by mask inflates the stomach/bowel in the chest, worsening lung compression). MANAGEMENT: (1) IMMEDIATE ENDOTRACHEAL INTUBATION for mechanical ventilation; (2) Insert an OROGASTRIC (NG) TUBE for continuous decompression of the bowel/stomach in the chest; (3) Position with head elevated and tilted toward the affected side (to let the unaffected lung expand); (4) Prepare for surgical repair (definitive treatment).
• MYELOMENINGOCELE (SPINA BIFIDA CYSTICA): A neural tube defect in which the spinal cord and its meninges protrude through an opening in the vertebral column, forming an exposed neural sac. Risk: infection (meningitis), trauma to the sac, and neurologic damage. NURSING PRIORITY AT BIRTH: (1) Cover the sac with a STERILE, SALINE-MOISTENED, non-adherent dressing to prevent drying and infection; (2) Position PRONE (face down) — relieves pressure on the sac and prevents rupture; (3) PREVENT INFECTION with meticulous sterile technique; (4) Monitor for HYDROCEPHALUS by measuring HEAD CIRCUMFERENCE daily; (5) Avoid latex products (high latex allergy risk in these infants); (6) Maintain warmth (do not place on a cold surface). Associated conditions: hydrocephalus (Chiari II malformation) requiring VP shunt; neurogenic bladder and bowel.
• IMPERFORATE ANUS: Anal opening is absent or displaced. KEY ASSESSMENT: the nurse checks the anus at EVERY newborn examination. Signs: no meconium passed in the first 24–48 hours, abdominal distension. Management: surgical repair (colostomy initially for high defects).
• GASTROSCHISIS AND OMPHALOCELE: Gastroschisis = intestines protrude through a defect LATERAL to the umbilicus (NO membranous covering — exposed bowel). Omphalocele = abdominal contents protrude through the BASE OF THE UMBILICAL CORD (covered by a membranous sac). NURSING: Cover exposed bowel with STERILE SALINE-MOISTENED gauze and plastic wrap/bowel bag; keep NPO; maintain warmth (large heat loss from exposed bowel); IV fluids; prepare for surgery.
• DOWN SYNDROME (TRISOMY 21): Most common chromosomal anomaly. Features: hypotonia, flat facial profile, upward-slanting eyes (epicanthal folds), single palmar crease (Simian crease), protruding tongue, short neck. Associated defects: congenital heart disease (AV canal/VSD in 40–50%), duodenal atresia (double-bubble sign), thyroid dysfunction, increased infection risk. Nursing: support feeding (hypotonia → poor suck), family support and referral to early intervention programs.
• CONGENITAL HEART DEFECTS (CHD): General nursing priorities — assess for CYANOSIS (central = pathologic), respiratory distress, feeding difficulties, tachycardia, and hepatomegaly. Support oxygenation, position of comfort, small frequent feedings (energy conservation), and prepare for cardiac catheterization or surgical repair.

Definitions

Section Title

Common Congenital Anomalies and Nursing Priorities

Common Mistakes

• Using bag-mask (BVM) ventilation for a suspected diaphragmatic hernia — this is CONTRAINDICATED and will worsen the condition.
• Positioning a myelomeningocele infant supine — should be PRONE to protect the neural sac.
• Dressing a myelomeningocele sac with dry gauze — it MUST be saline-moistened (sterile).
• Feeding an infant with suspected TEF — strictly NPO to prevent aspiration pneumonia.
• Forgetting to check for an anus in the newborn assessment — imperforate anus is identified only if the nurse LOOKS.
• Confusing gastroschisis (no sac, lateral to umbilicus) with omphalocele (has a sac, at base of umbilical cord) — surgical urgency differs (gastroschisis is higher risk of bowel compromise and infection).

Formulas

Exam Tips

• IDM hypoglycemia sequence: macrosomia → birth → glucose cut off → HYPERINSULINISM PERSISTS → hypoglycemia. This mechanism is frequently tested.
• First intervention for asymptomatic hypoglycemia: EARLY FEEDING (breastfeed or formula). IV dextrose is for symptomatic or feeding-intolerant cases.
• The IDM 5-problem list: Macrosomia, Hypoglycemia, Hypocalcemia, Polycythemia/Jaundice, RDS — memorize all 5.
• Jitteriness + low glucose → hypoglycemia. Jitteriness + normal glucose but prolonged QT → suspect HYPOCALCEMIA (also common in IDM).

Key Points

• Pathophysiology: Maternal hyperglycemia → excess glucose crosses the placenta → fetal hyperglycemia → fetal pancreatic beta cells hypertrophy → FETAL HYPERINSULINISM. High insulin = anabolic hormone → macrosomia (overgrowth). At birth, maternal glucose is suddenly cut off but HIGH INSULIN persists → NEONATAL HYPOGLYCEMIA.
• MACROSOMIA: birth weight >4,000 g (LGA). Associated with: shoulder dystocia and birth injuries (brachial plexus injury/Erb's palsy, fractured clavicle, cephalohematoma), operative delivery.
• HYPOGLYCEMIA: the most urgent metabolic complication after birth. Neonatal hypoglycemia is defined as blood glucose <40–45 mg/dL in the first 4 hours of life (thresholds vary slightly by source and gestational age; NLE commonly uses <40 mg/dL). Signs: jitteriness/tremors, irritability, hypotonia, poor feeding, lethargy, apnea, cyanosis, high-pitched cry, seizures.
• Other IDM complications: HYPOCALCEMIA (jitteriness + prolonged QT — caused by suppression of parathyroid gland), POLYCYTHEMIA (high hematocrit → hyperviscosity → poor perfusion, jaundice), HYPERBILIRUBINEMIA (from polycythemia), RESPIRATORY DISTRESS (insulin delays surfactant maturation → RDS even in term IDMs), CARDIOMEGALY (septal hypertrophy).
• NURSING MANAGEMENT: (1) Monitor blood glucose within 30–60 minutes of birth and as ordered (frequently in the first 24 hours). (2) Early feeding (breastfeed or formula) as the FIRST intervention for asymptomatic hypoglycemia. (3) If unable to feed or symptomatic hypoglycemia → IV DEXTROSE (D10W at 2 mL/kg over 1 minute as a mini-bolus, or continuous IV dextrose infusion). (4) Monitor for all associated complications. (5) Keep warm (prevent cold stress, which worsens hypoglycemia). (6) Document and report glucose values outside the normal range.
• Breastfeeding is ENCOURAGED for IDM infants — early, frequent feeding stabilizes glucose.
• Long-term: IDM infants are at higher risk for obesity and type 2 diabetes as they grow — family counseling is part of discharge teaching.

Definitions

Section Title

Infant of a Diabetic Mother (IDM)

Common Mistakes

• Forgetting to CHECK GLUCOSE in IDM infants early — glucose monitoring should begin within 30–60 minutes of birth.
• Treating asymptomatic mild hypoglycemia immediately with IV dextrose instead of trying EARLY FEEDING first.
• Forgetting the OTHER IDM complications beyond hypoglycemia — hypocalcemia, polycythemia, RDS, and cardiomegaly are all tested.
• Thinking IDM infants are ALWAYS large — in mothers with longstanding diabetic vascular disease, the infant may actually be SGA due to placental insufficiency.

Exam Tips

• Philippine law focus: RA 9288 = Newborn Screening Act (NBS); RA 9709 = Newborn Hearing Screening Act; RA 9173 = Nursing Act; DOH ENC Protocol = KMC and breastfeeding for LBW infants.
• NBS timing: heel-stick after 24–48 hours of milk feeding (not at birth), ideally day 3–5.
• KMC benefits for NLE: thermoregulation + breastfeeding + bonding + oxygenation + infection prevention. Any answer combining these is likely correct.
• Safe sleep = SUPINE at home. PRONE only in NICU under continuous monitoring for specific indications.

Key Points

• Parents of high-risk newborns experience fear, grief, guilt, altered bonding, and disrupted family roles. These are normal responses. The nurse's role includes emotional support, honest communication, and facilitating parent-infant attachment.
• KANGAROO MOTHER CARE (KMC): The infant is held skin-to-skin, upright between the mother's (or father's/partner's) breasts, with the head turned to one side (to keep the airway open). The parent's clothing covers the infant. Benefits: thermoregulation (parent's body acts as a natural warmer), oxygenation improvement, promotes breastfeeding (stimulates prolactin), facilitates parent-infant bonding, reduces infection risk (colonizes infant with parent's flora), shortens NICU stay. Philippine DOH ESSENTIAL NEWBORN CARE PROTOCOL promotes KMC for all stable preterm and LBW infants. KMC can be done even if the infant has an IV line, NG tube, or oxygen cannula, as long as the infant is hemodynamically stable.
• DISCHARGE TEACHING — KEY CONTENT: (1) DANGER SIGNS to report immediately: poor feeding/not eating, excessive sleepiness/lethargy, temperature instability (fever >38°C or hypothermia <36.5°C), fast or labored breathing (rate >60/min), persistent or worsening jaundice, fewer wet diapers than expected (<6/day after day 4), unusual crying. (2) NEWBORN SCREENING (NBS): as mandated by RA 9288 (Newborn Screening Act), blood sample is taken from a heel-stick on day 3–5 of life (after 24–48 hrs of milk feeding) and sent to an accredited screening center. Screens for 6 core conditions (expanded to more with expanded NBS): congenital hypothyroidism (CH), congenital adrenal hyperplasia (CAH), phenylketonuria (PKU), glucose-6-phosphate dehydrogenase deficiency (G6PD), maple syrup urine disease (MSUD), and galactosemia. Parents must be informed of results and the importance of repeat screening if invalid. (3) IMMUNIZATIONS: catch-up schedule for preterm infants is based on CHRONOLOGICAL (actual) age, not corrected age — BCG (at birth when weight ≥2 kg), Hepatitis B (at birth), and subsequent vaccines per EPI schedule. (4) FOLLOW-UP appointments: ophthalmology (ROP screening for preterm <32 weeks or <1,500 g), audiology (newborn hearing screening — RA 9709 Newborn Hearing Screening Act), developmental pediatrician, and primary care. (5) SAFE SLEEP: back-to-sleep position (supine), firm sleep surface, no loose bedding — to prevent Sudden Infant Death Syndrome (SIDS). Preterm infants may be initially positioned prone in the NICU under monitoring but go home in SUPINE. (6) HAND HYGIENE and limiting sick visitors — these infants remain immunocompromised for months. (7) BREASTFEEDING support: expressed breast milk is the preferred nutrition for preterm infants; arrange for a breast pump and lactation counseling.
• ETHICAL AND LEGAL CONTEXT (RA 9173): Under the Philippine Nursing Act of 2002, the nurse's responsibility includes informed consent facilitation, maintaining the confidentiality of health information, and advocating for the infant's best interests. In the NICU context, nurses collaborate with the neonatal team but independently assess, monitor, and intervene within their scope of practice.

Definitions

Section Title

Family Support, Kangaroo Mother Care, and Discharge Teaching

Common Mistakes

• Telling parents to delay vaccines until corrected age — immunizations follow CHRONOLOGICAL age (with exceptions for weight, e.g., BCG and Hep B at birth when weight is ≥2 kg).
• Discharging an infant without ensuring parents know the 6 danger signs — this is a safety and legal (RA 9173) issue.
• Forgetting newborn hearing screening (RA 9709) — it is mandatory and separate from NBS.
• Telling parents to place the infant prone at home for safe sleep — home sleep position is SUPINE (back to sleep).
