Chapter 23 On completion of this chapter, the reader will be able to: • Explain the purpose and components of the Apgar score. • Describe how to perform a physical assessment of a newborn. • Describe how to perform a gestational age assessment of a newborn. • Compare the characteristics of the preterm, late preterm, term, and postterm neonate. • Provide nursing care to assist the newborn to transition to extrauterine life. • Explain the elements of a safe environment. • Discuss phototherapy and the guidelines for teaching parents about this treatment. • Explain the purposes and methods for circumcision, the postoperative care of the circumcised infant, and parent teaching regarding circumcision. • Review the procedures for administering an intramuscular injection, performing a heelstick, collecting urine specimens, and venipuncture. • Evaluate pain in the newborn based on physiologic changes and behavioral observations. • Review anticipatory guidance nurses provide to parents before discharge. The foundation for providing comprehensive, family-centered newborn care is awareness of the mother’s preconception and prenatal history as well as intrapartal events. Recognition of risk factors (Box 23-1) enables the nurse to be more astute in observations and assessments and more likely to identify early signs of complications. This allows for earlier intervention and promotes positive outcomes. The primary goal of care in the first moments after birth is to assist the newly born infant to transition to extrauterine life by establishing effective respirations. If the infant is at term, is crying or breathing, and has good muscle tone, routine care can begin (Kattwinkel, Perlman, Aziz, et al., 2010). The infant is placed prone on the mother’s abdomen or chest, and the nurse assesses the airway. Slight extension of the neck helps keep the airway patent. Drying the infant with vigorous rubbing removes moisture to prevent evaporative heat loss and provides tactile stimulation to stimulate respiratory effort. The mother and her newborn are covered with a warm blanket (Niermeyer and Clarke, 2011). If the neonate is apneic or has gasping respirations, positive-pressure ventilation is needed. The heart rate is quickly assessed by grasping the base of the cord or by auscultating the left chest with a stethoscope. Count for 6 seconds and multiply by 10 to calculate the heart rate. It should be greater than 100 beats/min. The newborn’s trunk and lips should be pink; acrocyanosis is a normal finding (see Fig. 22-4) (Niermeyer and Clarke, 2011). If the newborn requires respiratory or circulatory support, the nurse and other members of the health care team (e.g., neonatologist, respiratory therapist) follow the American Heart Association guidelines for neonatal resuscitation (Kattwinkel, Perlman, Aziz, et al., 2010). The neonatal resuscitation algorithm directs the care (Fig. 23-1). As soon as possible after birth, the nurse places identically numbered bands on the infant’s wrist and ankle, on the mother, and on the father or significant other. An electronic infant security tag or abduction system alarm should be placed on all newborns to aid in protecting against infant abduction. The infant is footprinted with ink or a scanning device within 2 hours of birth (Vincent, 2009). (See later discussion of infant abduction.) The initial assessment of the neonate is performed immediately after birth using the Apgar score (Table 23-1) and a brief physical examination (Table 23-2). A gestational age assessment is completed within the first hours of birth in a stable newborn (Fig. 23-2). A more comprehensive physical assessment is completed within 24 hours of birth (Table 23-3).

AREA ASSESSED AND APPRAISAL PROCEDURE
NORMAL FINDINGS
DEVIATIONS FROM NORMAL RANGE: POSSIBLE PROBLEMS (ETIOLOGY)
AVERAGE FINDINGS
NORMAL VARIATIONS
Posture
Inspect newborn before disturbing for assessment
Refer to maternal chart for fetal presentation, position, and type of birth (vaginal, surgical), given that newborn readily assumes in utero position
Vertex: arms, legs in moderate flexion; fists clenched
Resistance to having extremities extended for examination or measurement, crying possible when attempted
Cessation of crying when allowed to resume curled-up fetal position (lateral)
Normal spontaneous movement bilaterally asynchronous (legs moving in bicycle fashion) but equal extension in all extremities
Frank breech: legs straighter and stiff, newborn assuming intrauterine position in repose for a few days
Prenatal pressure on limb or shoulder possibly causing temporary facial asymmetry or resistance to extension of extremities
Hypotonia, relaxed posture while awake (preterm or hypoxia in utero, maternal medications, neuromuscular disorder such as spinal muscular atrophy)
Hypertonia (chemical dependence, central nervous system [CNS] disorder)
Limitation of motion in any of extremities
Vital Signs
Check heart rate and pulses:
Thorax (chest)
Inspection
Visible pulsations in left midclavicular line, fifth intercostal space
Palpation
Apical pulse, fourth intercostal space 120-160 beats/min when awake
80-100 beats/min (sleeping) to 180 beats/min (crying); possibly irregular for brief periods, especially after crying
Tachycardia: persistent, ≥180 beats/min (respiratory distress syndrome [RDS]; pneumonia)
Bradycardia: persistent, ≤80 beats/min (congenital heart block, maternal lupus)
Quality: first sound (closure of mitral and tricuspid valves) and second sound (closure of aortic and pulmonic valves) sharp and clear
Murmur, especially over base or at left sternal border in interspace 3 or 4 (foramen ovale anatomically closing at approximately 1 yr)
Murmur (possibly functional)
Dysrhythmias: irregular rate
Sounds:
Heart on right side of chest (dextrocardia, often accompanied by reversal of intestines)
Peripheral pulses: femoral, brachial, popliteal, posterior tibial
Peripheral pulses equal and strong
Weak or absent peripheral pulses (decreased cardiac output, thrombus, possible coarctation of aorta if weak on left and strong on right)
Bounding
Obtain temperature:
Axillary: method of choice
Temporal and intraauricular thermometers not effective in measuring newborn temperature
Axillary: 37° C (98.6° F)
Temperature stabilized by 8-10 hr of age
36.5°-37.5° C (97.7°-100° F)
Heat loss: from evaporation, conduction, convection, radiation
Subnormal (preterm birth, infection, low environmental temperature, inadequate clothing, dehydration)
Increased (infection, high environmental temperature, excessive clothing, proximity to heating unit or in direct sunshine, chemical dependence, diarrhea and dehydration)
Temperature not stabilized by 6-8 hr after birth (if mother received magnesium sulfate, newborn less able to conserve heat by vasoconstriction; maternal analgesics possibly reducing thermal stability in newborn)
Observe and monitor respiratory rate and effort:
Observe respirations when infant is at rest
Observe respiratory effort
Count respirations for full minute
Auscultate breath sounds
Listen for sounds audible without stethoscope
40/min
Tendency to be shallow and irregular in rate, rhythm, and depth when infant is awake
Crackles may be heard after birth

First period (reactivity): 50-60/min
Second period: 50-70/min
Stabilization (1-2 days): 30-40/min
Crackles (fine)

Bradypnea: <25/min (maternal narcosis from analgesics or anesthetics, birth trauma)
Tachypnea: >60/min (RDS, transient tachypnea of the newborn, congenital diaphragmatic hernia)
Breath sounds:
Distress evidenced by nasal flaring, grunting, retractions, labored breathing
Stridor (upper airway occlusion)
Obtain blood pressure (BP) (usually not done in normal term infant)
Check oscillometric monitor BP cuff: BP cuff width affects readings, use appropriate-size cuff and palpate brachial, popliteal, or posterior tibial pulse (depending on measurement site)
