Midwife Licensure Exam Newborn & Neonatal Care — Normal Newborn Assessment & CareDetailed Explanation

APGAR Scoring System

The APGAR score is a standardized, rapid, 5-parameter assessment tool developed by Dr. Virginia Apgar in 1952 to evaluate a newborn's physiologic transition at birth. Each letter of the acronym corresponds to one assessed sign: Appearance (skin color), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), and Respiration (respiratory effort). Each sign is scored 0, 1, or 2, giving a maximum possible score of 10. The assessment is performed at exactly 1 minute and 5 minutes after birth. If the score at 5 minutes is below 7, the assessment is repeated every 5 minutes up to 20 minutes. The 1-minute score reflects the newborn's intrauterine experience and the acute response to birth, while the 5-minute score better predicts long-term neurologic outcomes. APGAR Score Criteria: • Appearance: Score 0 = blue or pale all over (central cyanosis or pallor); Score 1 = body pink but extremities blue (acrocyanosis); Score 2 = completely pink all over. • Pulse: Score 0 = absent heart rate; Score 1 = heart rate below 100/min; Score 2 = heart rate above 100/min. • Grimace: Score 0 = no response to stimulation; Score 1 = grimace only; Score 2 = vigorous cry, cough, or sneeze. • Activity: Score 0 = completely limp, no tone; Score 1 = some flexion of extremities; Score 2 = active motion, well-flexed extremities. • Respiration: Score 0 = absent; Score 1 = slow, irregular, weak cry; Score 2 = good, strong cry. Interpretation: • 7–10 = Good adjustment (routine care, observe). • 4–6 = Moderately depressed (stimulate, provide supplemental oxygen/airway support, prepare for intervention). • 0–3 = Severely depressed (immediate active resuscitation — bag-and-mask ventilation, chest compressions, possible medications). CRITICAL NLE POINT: APGAR score does NOT determine when to start resuscitation. Resuscitation is initiated immediately based on three rapid assessments done in the first 30 seconds: (1) Is the baby term? (2) Is the baby breathing or crying? (3) Does the baby have good muscle tone? If any answer is 'No,' resuscitation begins without waiting for the 1-minute APGAR. The APGAR score is a documentation and communication tool, not a resuscitation trigger. Acrocyanosis (bluish discoloration of the hands and feet) is NORMAL in the first 24 hours due to peripheral vasoconstriction and immature circulatory distribution. It costs 1 point in the Appearance category but does NOT indicate pathology. Central cyanosis (blue lips, tongue, trunk) is always abnormal and requires immediate action.

Gestational Age Assessment: New Ballard Score and Classification

Accurate determination of gestational age is essential because it determines the expected physiologic capabilities of the newborn, guides appropriate interventions, and identifies infants at heightened risk. The New Ballard Score (NBS), also called the Ballard Maturational Assessment of Gestational Age, is the most widely used bedside tool for estimating gestational age from 20 weeks through post-term. It is best performed within the first 12 hours of birth for very preterm infants (where neuromuscular tone changes rapidly after birth) and within 96 hours for term infants. The New Ballard Score combines two domains: 1. NEUROMUSCULAR MATURITY (6 signs, each scored –1 to 5): • Posture: A preterm infant lies with limbs extended; a term infant lies with limbs well flexed. • Square Window (wrist): Flex the wrist — the angle between the palm and forearm decreases with increasing maturity (term = 0°, very preterm = 90°). • Arm Recoil: Flex the arm for 5 seconds, then release — a mature infant's arm snaps back quickly into full flexion (180° = 0, brisk recoil = term). • Popliteal Angle: With the infant supine, flex the thigh against the abdomen and extend the knee — the angle behind the knee decreases with maturity (term ≈ 80–90°). • Scarf Sign: Draw the arm across the chest — a preterm infant's elbow passes the midline easily; a term infant resists (elbow stops at midline or before). • Heel-to-Ear: With pelvis flat, move the foot toward the ear — a preterm infant allows this easily; a term infant resists significantly. 2. PHYSICAL MATURITY (6 signs, each scored 0–5): • Skin: Preterm = sticky, transparent, fragile; term = smooth, pink with superficial peeling; post-term = cracked, parchment-like, leathery. • Lanugo: Preterm = abundant; term = mostly absent. • Plantar Creases: Preterm = absent (only a single crease anteriorly); term = creases covering the entire sole. • Breast: Preterm = imperceptible bud; term = 5–10 mm breast bud with stippled areola. • Eye/Ear: Preterm = eyelids fused, ear flat (no cartilage); term = eyes open, ear stiff with cartilage. • Genitalia (Male): Preterm = testes in canal, few rugae; term = testes descended, deep rugae. • Genitalia (Female): Preterm = clitoris and labia minora prominent; term = large labia majora covering clitoris and minora. Scores from both domains are added. The total score is plotted on a maturity rating table to estimate gestational age in weeks. CLASSIFICATION BY GESTATIONAL AGE: • Preterm (premature): Less than 37 weeks gestation. • Term: 37–42 weeks (some sources define full term as 38–42 weeks). • Post-term (postmature): Greater than 42 weeks. CLASSIFICATION BY WEIGHT FOR GESTATIONAL AGE (plotted on growth chart): • SGA (Small for Gestational Age): Birth weight below the 10th percentile for gestational age. Risk: hypoglycemia, hypothermia, polycythemia. • AGA (Appropriate for Gestational Age): Birth weight between the 10th and 90th percentile. Expected growth. • LGA (Large for Gestational Age): Birth weight above the 90th percentile. Often seen in infants of diabetic mothers (IDM). Risk: hypoglycemia (fetal hyperinsulinism), birth trauma, polycythemia. COMBINED RISK: A preterm-SGA infant carries the compounded risks of both prematurity (immature organ systems) and intrauterine growth restriction (depleted energy stores, impaired glucose regulation).

Normal Newborn Vital Signs and Physical Measurements

Knowing the exact normal ranges for all newborn vital signs and measurements is a high-yield NLE requirement. Values outside these ranges require immediate nursing assessment and intervention. All vital signs should be assessed in a head-to-toe systematic manner, and each measurement carries its own normal range and clinical significance. VITAL SIGNS: 1. HEART RATE (HR): Normal = 110–160 beats/min. Measure by auscultation at the apical pulse (4th intercostal space, midclavicular line) for a FULL MINUTE because newborns have irregular rhythms. HR can transiently rise to 180 bpm during crying or decrease to 100 bpm during deep sleep — these are acceptable variations. Sustained bradycardia (below 100/min) or tachycardia (above 160/min at rest) requires investigation. 2. RESPIRATORY RATE (RR): Normal = 30–60 breaths/min. Respirations are characteristically abdominal (diaphragmatic), irregular, and may include brief pauses of up to 15–20 seconds (periodic breathing) — this is normal. Count for a FULL MINUTE because of irregularity. RR above 60/min (tachypnea) is a sign of respiratory distress. Signs of respiratory distress include: grunting (best described as an expiratory grunt), nasal flaring, intercostal and subcostal retractions, and seesaw (paradoxical) chest movement. 3. TEMPERATURE: Normal axillary = 36.5–37.5°C (97.7–99.5°F). Axillary is the PREFERRED site in the newborn — rectal temperature is avoided because of risk of rectal perforation and vagal stimulation causing bradycardia. Oral measurement is NOT used in newborns. Hypothermia (below 36.5°C) is a medical emergency requiring immediate rewarming. 4. BLOOD PRESSURE: Approximately 60–80 mmHg systolic / 40–50 mmHg diastolic. NOT routinely measured in the healthy term newborn but assessed in infants with suspected cardiovascular compromise. 5. BLOOD GLUCOSE: Keep above 45 mg/dL. Neonatal hypoglycemia is clinically significant at below 40–45 mg/dL. Signs: jitteriness/tremors, poor feeding, lethargy, hypotonia, high-pitched cry, apnea. At-risk groups: LGA/IDM, SGA, preterm, infants of mothers who received tocolytics (terbutaline) or beta-blockers. PHYSICAL MEASUREMENTS: • WEIGHT: Normal = 2,500–4,000 g (average ~3,400 g). Physiologic weight loss of 5–10% of birth weight in the first 3–5 days is normal (due to loss of extracellular fluid, meconium, and establishing feeding). This weight is regained by 10–14 days. Weight loss exceeding 10% or failure to regain birth weight by 2 weeks warrants evaluation. • LENGTH: Normal = 45–55 cm (average ~50 cm). Measured crown to heel. • HEAD CIRCUMFERENCE (HC): Normal = 33–35 cm. This is approximately 2–3 cm larger than chest circumference — a key exam fact. HC is larger than chest at birth and equalizes at approximately 6 months to 2 years. HC exceeding 37 cm = macrocephaly (hydrocephalus?); below 32 cm = microcephaly. • CHEST CIRCUMFERENCE: Normal = 30–33 cm. Measured at the nipple line. • ABDOMINAL CIRCUMFERENCE: Variable, used as comparison with HC. FONTANELLES: • Anterior fontanelle (diamond-shaped): 2–3 cm × 3 cm, closes at 12–18 months. Bulging = increased ICP (meningitis, hydrocephalus). Sunken = dehydration. • Posterior fontanelle (triangular): smaller, closes by 6–8 weeks. MECONIUM: The first stool. Normal meconium is dark green-black, sticky, and odorless. It should be passed within the FIRST 24 HOURS. Failure to pass meconium within 24 hours suggests Hirschsprung's disease (aganglionic megacolon) or imperforate anus. FIRST VOID: Expected within the first 24 hours (up to 48 hours). After day 4, expect 6 or more wet diapers per day as an indicator of adequate hydration and feeding.

Newborn Primitive Reflexes

Primitive reflexes are involuntary, stereotyped motor responses present at birth that reflect an intact central nervous system (CNS), specifically the brainstem and spinal cord. Their presence confirms neurologic integrity at birth, and their gradual disappearance (as the higher cortical centers mature) confirms normal neurologic development over infancy. For the NLE, the nurse must know each reflex, how to elicit it, what the normal response is, when it disappears, and what the absence or asymmetry of the reflex may indicate. KEY PRIMITIVE REFLEXES: 1. ROOTING REFLEX: Elicited by stroking the corner of the baby's mouth, cheek, or lip → the baby turns the head toward the stimulus and opens the mouth. Aids in finding the nipple for feeding. Disappears at approximately 3–4 months. NURSING RELEVANCE: If this reflex is present, it confirms readiness to feed by mouth. 2. SUCKING REFLEX: Elicited by placing a finger, nipple, or pacifier in the mouth → the baby sucks rhythmically. Present at birth in term infants; may be weak in preterm infants. Disappears at approximately 10–12 months. NURSING RELEVANCE: A weak or absent sucking reflex in a preterm infant indicates the need for alternative feeding (gavage/nasogastric tube). 3. PALMAR GRASP: Elicited by placing a finger in the infant's palm → the baby grasps the finger firmly (the nurse can often lift the baby slightly). Disappears at approximately 3–4 months as voluntary hand use develops. NURSING RELEVANCE: Asymmetric or absent palmar grasp may indicate brachial plexus injury or CNS depression. 4. PLANTAR GRASP: Elicited by applying pressure to the ball of the foot → all toes curl downward (plantarflexion). Disappears at approximately 8–9 months. Distinguished from the Babinski reflex by the site of stimulation. 5. MORO REFLEX (Startle Reflex): Elicited by a sudden jarring stimulus — place the baby supine, support the head slightly, then allow the head to drop back (or create a loud noise or sudden movement). NORMAL RESPONSE: Bilateral SYMMETRIC arm abduction and extension, fingers fan open (extension), followed by arm adduction into a midline embrace (C-shaped curve of the thumb and index finger). The cry that follows is expected. Disappears at approximately 4–6 months. CRITICAL POINT: ASYMMETRIC Moro reflex (one arm responds, the other does not or responds weakly) is ABNORMAL and suggests a fractured clavicle (especially after difficult delivery, shoulder dystocia) or brachial plexus injury such as Erb's palsy (C5–C6 injury). An ABSENT Moro in a term infant suggests CNS depression or severe neurologic injury. 6. TONIC NECK REFLEX (Fencing Position): Elicited by turning the baby's head to one side while supine → the arm and leg on the side the head faces EXTEND, while the contralateral arm and leg FLEX (the baby looks like a fencer lunging). Fades at approximately 4–6 months. An obligatory tonic neck reflex (one that persists beyond 6 months or that the baby cannot break voluntarily) is abnormal. 7. BABINSKI REFLEX: Elicited by stroking the lateral aspect of the sole of the foot from heel to toe → the great toe dorsiflexes (extends upward) and the other toes fan outward. IMPORTANT: This is NORMAL in infants and disappears at approximately 12–24 months. In adults, a positive Babinski is ALWAYS PATHOLOGIC (indicates upper motor neuron lesion). The NLE tests this distinction frequently. 8. STEPPING/DANCING REFLEX: Hold the baby upright with feet touching a flat surface → the baby makes stepping movements. Disappears at approximately 4–8 weeks. This is a primitive reflex and does NOT indicate readiness for walking. 9. GALANT REFLEX (Trunk Incurvation): Hold the baby prone, stroke along the paravertebral muscles → the trunk curves toward the stimulated side. Disappears at approximately 4–6 months. Asymmetry may suggest spinal cord injury. 10. SWIMMING REFLEX: Place the baby on the abdomen in water → the baby makes coordinated swimming movements. This reflex should NOT be used as a basis for infant swimming lessons as it does not protect against drowning.

Thermoregulation in the Newborn

Thermoregulation — the ability to maintain a stable core body temperature — is severely limited in the newborn due to multiple physiologic characteristics: large body surface area relative to mass, thin skin with minimal subcutaneous fat, high vascularity close to the skin surface, and an inability to shiver (the primary heat-generating mechanism in older humans). Understanding heat loss mechanisms and how to prevent them is one of the most clinically and exam-critical topics in newborn care. WHY NEWBORNS LOSE HEAT RAPIDLY: • Relatively large head (accounts for ~20% of total body surface area) — a major heat-loss area. • Thin, poorly keratinized skin allows rapid evaporative and radiative heat loss. • Little brown adipose tissue (BAT) in very preterm infants. • Inability to shiver due to immature hypothalamic thermoregulatory center. HEAT PRODUCTION IN THE NEWBORN — NON-SHIVERING THERMOGENESIS: When cold-stressed, the newborn metabolizes BROWN ADIPOSE TISSUE (BAT, also called brown fat) found primarily in the nape of the neck, between the scapulae, around the kidneys, and in the mediastinum. BAT is specialized adipose tissue with high mitochondrial content that generates heat through uncoupled oxidative phosphorylation. This process is energy-intensive and consumes significant oxygen and glucose. COLD STRESS AND ITS CONSEQUENCES: Cold stress (hypothermia or even mild cold exposure below the neutral thermal zone) triggers a cascade of harmful effects: 1. Increased BAT metabolism → increased oxygen consumption → pulmonary vasoconstriction → respiratory distress (the baby 'breathes harder' to meet oxygen demand). 2. Increased glucose utilization for thermogenesis → NEONATAL HYPOGLYCEMIA. 3. Pulmonary vasoconstriction → persistence or return to fetal circulation patterns → worsening hypoxia. 4. Metabolic acidosis from anaerobic metabolism. 5. Poor weight gain as energy reserves are consumed for heat rather than growth. FOUR MECHANISMS OF HEAT LOSS AND NURSING INTERVENTIONS: 1. EVAPORATION — Heat lost through conversion of water on the skin to vapor. • Highest at birth (wet amniotic fluid on skin). • INTERVENTION: Thorough and IMMEDIATE drying with warm towels; replace wet towels. Delay the first bath (at least 6 hours, ideally 24 hours). This is the FIRST and most important immediate action under the EINC protocol. 2. CONDUCTION — Heat transferred from the newborn to cooler solid surfaces in direct contact. • Examples: cold scale, cold table, cold blanket, cold nurse's hands. • INTERVENTION: Warm all surfaces, blankets, linens, and equipment before contact. Use pre-warmed radiant warmer. Pre-warm the nurse's hands. 3. CONVECTION — Heat transferred to cooler surrounding air or air currents. • Examples: air conditioning vents, open windows, drafts from corridor. • INTERVENTION: Keep the newborn away from air conditioning vents and drafts. Use incubators for very preterm infants. Maintain closed incubator porthole technique. 4. RADIATION — Heat transferred to cooler solid objects NOT in direct contact. • Examples: cold window glass, outer walls, cold incubator walls in winter. • INTERVENTION: Keep newborn away from cold windows and outer walls. Use a radiant warmer or incubator. Double-wall incubators prevent radiant heat loss. NEUTRAL THERMAL ENVIRONMENT (NTE): The NTE is the environmental temperature range in which the newborn can maintain a normal body temperature with the MINIMUM metabolic expenditure and oxygen consumption. In an NTE, the baby does not need to generate extra heat. For term newborns, the NTE is maintained by skin-to-skin care with the mother. For preterm infants, it requires a radiant warmer or incubator set to the appropriate temperature for gestational age and postnatal age. PRACTICAL NURSING INTERVENTIONS: • Place a cap on the baby's head immediately (the head is the largest surface area and greatest source of evaporative and radiative loss). • Use skin-to-skin (kangaroo mother care) — the mother's chest regulates the baby's temperature better than an incubator. • Delay the first bath for at least 6 hours (ideally 24 hours) — the vernix caseosa is an insulator. • Cover the baby with warmed blankets. • Use a radiant warmer or incubator for preterm or hypothermic infants.

EINC/Unang Yakap Protocol: Philippine Essential Intrapartum and Newborn Care

The Essential Intrapartum and Newborn Care (EINC) protocol, locally known as 'Unang Yakap' (First Embrace), is the Philippine Department of Health's evidence-based, standardized protocol for immediate newborn care. It was institutionalized through DOH Administrative Order 2009-0025 and is fully aligned with WHO/UNICEF recommendations. Every Filipino nurse working in a birthing facility is expected to implement and advocate for EINC. It is a consistently tested topic in the NLE because it represents both clinical competency and compliance with Philippine healthcare policy — both of which are within the professional scope of nursing practice under RA 9173. THE FOUR TIME-BOUND CORE STEPS OF UNANG YAKAP (in order of implementation): STEP 1: IMMEDIATE AND THOROUGH DRYING (within the first 30 seconds) The baby is dried thoroughly with a clean, dry, warm cloth — starting with the face, then the head (where evaporative loss is greatest), then the body and extremities. This is simultaneously a THERMOREGULATION intervention (prevents evaporative and conductive heat loss) and a STIMULATION intervention (the drying motion stimulates breathing). The wet cloth is discarded and a dry one used. Do NOT wipe off the vernix caseosa (it is an antimicrobial lubricant). Do NOT suction the baby routinely if the baby is vigorous and crying — routine suctioning is unnecessary and potentially harmful (vagal stimulation, mucosal injury). TIMING: Complete within 30 seconds. STEP 2: EARLY SKIN-TO-SKIN CONTACT Immediately after drying, the naked baby is placed prone (face to the side to maintain airway) on the mother's bare chest or abdomen. Both are covered with a dry blanket and the baby is given a cap. Skin-to-skin contact provides: • WARMTH (mother's chest temperature adjusts to baby's needs — 'thermoregulatory synchrony'). • COLONIZATION with maternal skin flora (protective against hospital-acquired pathogens). • BONDING and attachment. • STIMULATION of oxytocin and prolactin release (aids uterine contraction and milk production). • BASIS for EARLY BREASTFEEDING. STEP 3: PROPERLY TIMED CORD CLAMPING The umbilical cord is clamped and cut AFTER cord pulsations stop, typically 1–3 minutes after delivery. This is called 'delayed cord clamping' or 'optimal cord clamping.' Rationale: At birth, approximately 80–100 mL of additional blood is delivered to the baby from the placenta through the still-pulsating cord. This placental transfusion: • Increases the baby's blood volume and iron stores. • Reduces the incidence of iron deficiency anemia in the first year of life. • Reduces the need for blood transfusion in preterm infants. NOTE: 'Cord milking' (manual squeezing of the cord toward the baby) may be used as an alternative for very preterm infants if delayed clamping is not feasible. Cord is cut between two clamps — clean blade, sterile technique. In Philippine rural settings, a designated cord cutter (midwife or nurse) performs this under aseptic conditions. STEP 4: NON-SEPARATION OF MOTHER AND NEWBORN FOR EARLY INITIATION OF BREASTFEEDING The baby remains skin-to-skin with the mother (rooming-in) for at least the first 90 minutes or until after the first successful breastfeed. The baby should not be taken to the nursery for routine procedures (bathing, weighing, eye prophylaxis, vitamin K injection) UNTIL after the first breastfeed. Early initiation of breastfeeding within 1 hour of birth: • Provides colostrum (rich in antibodies, specifically secretory IgA, lactoferrin, and leukocytes). • Stimulates uterine contraction (reducing postpartum hemorrhage in the mother). • Establishes milk supply. • Reduces neonatal mortality. After the first breastfeed, routine newborn care procedures (eye prophylaxis, vitamin K, weighing, bathing — delayed at least 6 hours) are performed. WHAT EINC DISCOURAGES (to be highlighted for the NLE): • Routine nasopharyngeal suctioning of vigorous babies. • Early (immediate) bathing. • Footprinting and labeling before skin-to-skin. • Routine separation of mother and baby. • Administration of prelacteal feeds (formula, glucose water, etc.). • Early (before pulsation stops) cord clamping.

Prophylactic Medications and Immunizations at Birth

Immediately following the first breastfeed (per EINC), the newborn receives essential prophylactic medications and the first scheduled immunizations. These are evidence-based, DOH-mandated interventions that prevent serious or life-threatening conditions. 1. VITAMIN K (PHYTONADIONE) • Dose: 0.5 mg IM for preterm infants; 1 mg IM for term infants. • Route: Intramuscular injection into the vastus lateralis (anterolateral thigh) — the preferred IM site in neonates. • Timing: Within the first hour after birth (per DOH), ideally after the first breastfeed per EINC. • Purpose: Prevents Vitamin K-Deficiency Bleeding (VKDB), formerly called Hemorrhagic Disease of the Newborn (HDN). • Rationale: The neonatal gut is sterile at birth and cannot produce Vitamin K (which requires gut bacteria synthesis). Newborns have very low stores of Vitamin K-dependent clotting factors (II, VII, IX, X). Without prophylaxis, neonates are at risk for uncontrolled bleeding — including life-threatening intracranial hemorrhage. • Breast milk contains very little Vitamin K (unlike formula, which is fortified), making breastfed infants particularly at risk. • NLE NOTE: A single IM injection is the gold-standard method. Some countries use oral Vitamin K, but the Philippine standard is IM. 2. ERYTHROMYCIN 0.5% OPHTHALMIC OINTMENT • Purpose: Prophylaxis against ophthalmia neonatorum (neonatal conjunctivitis), specifically gonococcal and chlamydial eye infections acquired from the mother's birth canal during vaginal delivery. • Application: A thin line (approximately 1–2 cm) of ointment is instilled into the lower conjunctival sac of EACH EYE. Gently close the eyelid. Excess ointment may be wiped away after 1 minute. • Do NOT irrigate the eye after application. • Timing: Within 1 hour of birth (per EINC, after the first breastfeed — some protocols do it immediately after delivery). • Historical note: Silver nitrate was used previously but caused chemical conjunctivitis and is no longer recommended. Erythromycin is the current DOH-approved agent. • Gonococcal ophthalmia neonatorum left untreated can cause corneal ulceration and blindness. 3. HEPATITIS B VACCINE (FIRST DOSE) • Dose: 0.5 mL IM into the vastus lateralis (separate site from Vitamin K). • Timing: Within 12 hours of birth (some protocols state within 24 hours). • Purpose: Prevents vertical transmission of Hepatitis B virus (HBV) from HBsAg-positive mothers to neonates. The risk of perinatal HBV transmission can be as high as 90% in highly infectious mothers. • If the mother is HBsAg-positive: administer BOTH the HBV vaccine AND Hepatitis B Immunoglobulin (HBIG) within 12 hours of birth (at different sites) to provide both passive and active immunity. • Subsequent doses: at 6 weeks and 14 weeks (part of the Philippine EPI schedule). 4. BCG (BACILLE CALMETTE-GUÉRIN) VACCINE • Dose: 0.05 mL intradermal (ID) injection into the right upper arm (deltoid region). • Timing: At birth (or as soon as possible after birth). • Purpose: Prevents severe forms of tuberculosis in children — specifically TB meningitis and miliary (disseminated) TB — which are especially dangerous for infants given the high TB burden in the Philippines. • A papule (small raised wheal) forms at the injection site. This is EXPECTED. After 2–4 weeks, a pustule forms, which ulcerates and then heals, leaving a scar (BCG scar) — this is NORMAL and does NOT indicate infection or need for treatment. • BCG does NOT prevent pulmonary TB in adults but is highly effective against severe disseminated TB in children. • Under the Philippine Expanded Program on Immunization (EPI), BCG at birth is MANDATORY for all newborns. IMPORTANT DRUG ADMINISTRATION PRINCIPLES FOR NEWBORNS: • Vastus lateralis (anterolateral thigh) is the preferred IM site for ALL IM injections in neonates (greater muscle mass, no major nerves or vessels at risk). • Use a 25-gauge, 5/8-inch needle for IM injections in neonates. • BCG is INTRADERMAL (ID), not IM — critical distinction. • Document: drug name, dose, route, site, time, and lot number for all vaccines.

Newborn Screening: Republic Act 9288

The Newborn Screening Act of 2004 (Republic Act No. 9288) is Philippine law that requires all newborns to undergo metabolic screening within the first days of life to detect serious, treatable conditions before they cause irreversible damage. This is a high-yield NLE topic because it combines clinical knowledge with legal/policy awareness — both of which are within the nurse's scope under RA 9173. LEGAL BASIS AND MANDATE: RA 9288 mandates that all hospitals, lying-in clinics, birthing homes, health centers, and other health facilities offering birthing services MUST perform newborn screening. The law covers all liveborn babies regardless of gestational age or birth weight. SCREENING SAMPLE COLLECTION: • Method: HEEL-PRICK (filter paper blood spot collection). • How to collect: Clean the heel with an alcohol swab and allow to dry. Puncture the lateral surface of the heel (NOT the center/posterior heel — risk of calcaneal osteomyelitis and nerve injury). Allow blood to flow freely and saturate all circles on the filter paper card completely. Allow to air dry at room temperature for 3 hours before sending. • Timing: IDEALLY BETWEEN 24 AND 72 HOURS AFTER BIRTH. WHY 24 HOURS? Most metabolic screening tests are feeding-dependent — the baby must have ingested sufficient protein (from breast milk or formula) for the metabolites to accumulate to detectable levels. A sample drawn BEFORE 24 hours may give a FALSE NEGATIVE result. If the baby is discharged before 24 hours (e.g., early home delivery), the heel prick should be performed as soon as possible and REPEATED after 24 hours. • If the sample is drawn before 24 hours: it must be REPEATED after the 24-hour mark. • Maximum recommended timing: Before 3–7 days of age for best yield. DISORDERS DETECTED (CORE BASIC PANEL — 6 conditions): 1. CONGENITAL HYPOTHYROIDISM (CH): Deficiency of thyroid hormone from birth. If untreated → intellectual disability, growth retardation, cretinism. Treated with thyroid hormone replacement (levothyroxine) — if started within 2 weeks, normal development is possible. CH is the most common preventable cause of intellectual disability. 2. CONGENITAL ADRENAL HYPERPLASIA (CAH): Deficiency of 21-hydroxylase enzyme → impaired cortisol and aldosterone synthesis → virilization of female fetuses, adrenal crisis (salt-wasting) in both sexes. Treated with corticosteroid replacement. 3. GALACTOSEMIA (GAL): Deficiency of GALT enzyme → inability to metabolize galactose (a component of lactose in breast milk and formula) → galactose accumulates → liver damage, intellectual disability, cataracts, sepsis. Treated by eliminating lactose/galactose from the diet (use soy-based formula). IMPORTANT: Breastfeeding must be STOPPED immediately if galactosemia is confirmed. 4. PHENYLKETONURIA (PKU): Deficiency of phenylalanine hydroxylase → phenylalanine accumulates → brain damage, intellectual disability. Treated by a phenylalanine-restricted diet. Classic presentation: musty odor of urine, fair skin/hair (phenylalanine inhibits melanin synthesis), developmental delay. 5. GLUCOSE-6-PHOSPHATE DEHYDROGENASE (G6PD) DEFICIENCY: Most common enzyme deficiency in the Philippines (high prevalence in Filipino males, as it is X-linked recessive). G6PD protects red blood cells from oxidative stress. Deficiency → hemolytic anemia triggered by oxidative stressors (fava beans, certain medications: dapsone, primaquine, nitrofurantoin, certain sulfa drugs, naphthalene mothballs). Treated by AVOIDANCE of triggers; no specific enzyme replacement. 6. MAPLE SYRUP URINE DISEASE (MSUD): Deficiency of branched-chain alpha-keto acid dehydrogenase → accumulation of leucine, isoleucine, and valine → neurotoxicity. Classic sign: urine smells like MAPLE SYRUP or burnt sugar. Treated by a diet restricted in branched-chain amino acids. EXPANDED NEWBORN SCREENING PANEL: The Philippines now offers an expanded panel detecting 28+ disorders including organic acidemias, fatty acid oxidation defects, amino acid disorders, and others through tandem mass spectrometry (MS/MS). RESULT AND FOLLOW-UP: • Screening results are sent to the health facility and the family within 7–14 days. • A POSITIVE (abnormal) screen requires CONFIRMATORY TESTING — it does NOT mean the baby definitely has the condition (false positives occur). • The nurse must counsel parents: a positive screen result needs confirmation and does not constitute a diagnosis. • Confirmed cases are referred to a metabolic specialist (pediatric endocrinologist, metabolic dietitian). NURSE'S RESPONSIBILITIES UNDER RA 9288: 1. Inform parents about the purpose and importance of newborn screening (informed consent/education). 2. Collect the sample at the correct time (24–72 hours) and using correct technique. 3. Ensure proper labeling and transport of the filter paper card. 4. Facilitate follow-up for positive results. 5. Maintain confidentiality of results.

Normal Newborn Variations vs. Abnormal Findings

A crucial competency for the NLE is the ability to distinguish NORMAL physiologic variations in the newborn — which require only parental reassurance — from ABNORMAL findings that require immediate nursing action or physician notification. Filipino nurses encounter these situations daily, and parents frequently seek reassurance or express alarm about findings that are entirely normal. Conversely, a nurse who mistakes a pathologic finding for a normal variation endangers the newborn. NORMAL VARIATIONS (REASSURE — NO ACTION NEEDED): 1. ACROCYANOSIS: Bluish discoloration of the hands and feet in the first 24 hours due to peripheral vasoconstriction and immature peripheral circulation. Body and mucous membranes are PINK. Normal. No oxygen needed. 2. MILIA: Tiny, white, pinhead-sized sebaceous cysts found on the nose, chin, cheeks, and forehead. Caused by blocked sebaceous glands. Resolve spontaneously within weeks. DO NOT squeeze or apply creams. 3. MONGOLIAN SPOTS: Flat, irregular, bluish-gray or grayish-green pigmented areas over the sacrum, buttocks, and sometimes extremities. Extremely common in Filipino, Asian, African, and other dark-skinned infants. Caused by melanocytes in the deep dermis. They are BENIGN and fade slowly over the first few years. CRITICAL CLINICAL POINT: Mongolian spots can be MISTAKEN for BRUISES. The nurse MUST document their location, size, and shape in the newborn record to prevent future misidentification as child abuse. 4. ERYTHEMA TOXICUM (Neonatal Erythema Toxicum): A benign rash appearing in the first 2–3 days of life. Characterized by small, erythematous (red) macules and papules with a white or pale yellow center (resembling flea bites or pustules), scattered over the trunk, buttocks, and extremities. NOT present on the palms or soles. Cause is unknown; benign and self-limiting. NO treatment needed. Must be differentiated from the vesicular rash of neonatal herpes (which IS on palms/soles and IS serious). 5. CAPUT SUCCEDANEUM: Diffuse, edematous, soft swelling of the scalp caused by prolonged pressure on the presenting part during labor and delivery. CROSSES suture lines. Present at birth. Resolves within 1–3 days. Not associated with significant complications. Benign — reassure parents. 6. PHYSIOLOGIC PEELING (Desquamation): Peeling of the skin, especially on the hands and feet, in the first days of life. Normal, especially in post-term infants. No treatment (no lotion or oil is needed). Resolves spontaneously. 7. PSEUDOMENSTRUATION AND VAGINAL DISCHARGE: A small amount of blood-tinged mucous vaginal discharge in female newborns, caused by withdrawal of maternal estrogen. Disappears within 1–2 weeks. Reassure parents. 8. BREAST ENGORGEMENT: Both male and female newborns may have palpable breast tissue due to maternal estrogen withdrawal. May express a small amount of milky fluid ('witch's milk'). Normal. DO NOT squeeze the breast tissue (risk of mastitis). 9. PHYSIOLOGIC JAUNDICE: Yellowing of the skin and sclerae appearing on DAY 2–3 of life, peaking at days 3–5, and resolving by day 7–10 in term infants (up to 14 days in preterm). Caused by rapid breakdown of fetal hemoglobin and immature liver conjugation capacity. Serum bilirubin usually remains below 12 mg/dL in term infants. Treatment: phototherapy if bilirubin reaches treatment threshold. Reassure parents it is expected but emphasize the need for monitoring. ABNORMAL FINDINGS (REPORT — ACTION REQUIRED): 1. CENTRAL CYANOSIS: Blue lips, tongue, oral mucosa, or trunk → ALWAYS abnormal → immediate intervention (oxygen, call physician/code team). 2. CEPHALOHEMATOMA: A swelling caused by subperiosteal bleeding (between the periosteum and skull bone). Does NOT cross suture lines (unlike caput succedaneum). Caused by birth trauma (difficult delivery, vacuum extraction, forceps). Appears hours to days after birth. The blood is confined and absorbed slowly over weeks to months. Major complication: HYPERBILIRUBINEMIA (as the blood breaks down → excess bilirubin) → monitor for jaundice. Large cephalohematomas may also indicate skull fracture — arrange X-ray. 3. PATHOLOGIC JAUNDICE: Jaundice appearing within the FIRST 24 HOURS of life (day 0–1). Always abnormal — indicates hemolytic disease (Rh/ABO incompatibility, G6PD deficiency). Requires urgent investigation and treatment. 4. BULGING FONTANELLE: Indicates increased intracranial pressure (meningitis, hydrocephalus, intracranial hemorrhage). Report immediately. 5. SINGLE (SIMIAN) PALMAR CREASE WITH OTHER DYSMORPHIC FEATURES: May indicate Down syndrome (Trisomy 21) — warrants karyotyping and pediatrician evaluation. Note: A single palmar crease alone is NOT diagnostic of Down syndrome. 6. RESPIRATORY DISTRESS SIGNS: Respiratory rate above 60/min sustained, grunting, nasal flaring, intercostal retractions, seesaw breathing — report immediately → potential respiratory distress syndrome, transient tachypnea of the newborn, or congenital pneumonia. 7. FAILURE TO PASS MECONIUM IN 24 HOURS or first void in 24–48 hours → evaluate for Hirschsprung's disease, imperforate anus, or urinary tract anomaly. 8. ASYMMETRIC MORO REFLEX — suspect clavicle fracture or brachial plexus injury. 9. ABSENT REFLEXES — suggests CNS depression, severe injury, or congenital anomaly.

An APGAR of 0 at 1 minute indicates no spontaneous physiologic function — this is a complete neonatal emergency requiring the full neonatal resuscitation protocol. Under Maslow's hierarchy, physiologic needs (airway, breathing, circulation) are the absolute priority. Note: Ideally, this baby's resuscitation should have ALREADY been started at 30 seconds based on initial assessment of absent breathing and heart rate — NOT after waiting for the formal 1-minute APGAR.

The most critical abnormal finding is the temperature of 36.3°C — this is hypothermia. Even mild hypothermia in a newborn triggers non-shivering thermogenesis, increasing oxygen and glucose consumption, which can lead to hypoglycemia and respiratory distress. The nurse's PRIORITY diagnosis is 'Hypothermia related to immature thermoregulatory mechanisms.' Apply Maslow — thermoregulation is a physiologic survival need. Implement EINC thermoregulation measures immediately.
