THE FIRST HOUR OF LIFE The primary focus at this time is the transition from intrauterine to extrauterine life, with an introduction to  family members as the neonate’s condition warrants. NEONATAL ASSESSMENT DATA BASE (FULL-TERM) Circulation Apical pulse may fluctuate from 110–180 beats per minute (bpm). Blood pressure 60–80 mm Hg (systolic), 40–45 mm Hg (diastolic). Heart Sounds: Located in mediastinum with point of maximal intensity just to the left of the midsternum at third or  fourth intercostal space. Murmurs common during the first few hours of life. Umbilical cord white and gelatinous; contains two arteries and one vein. Elimination May void at birth May have passed meconium at birth Food/Fluid Weight: 2500–4000 g (5 lb 8 oz–8 lb 13 oz) Length: 44–55 cm (18–22 in) Skin turgor elastic (varies according to gestational age) Neurosensory Muscle Tone: Hypertonic flexion of all extremities. Awake and active, demonstrates sucking reflex for first 30 min following birth (first period of reactivity). Asymmetrical appearance (molding, edema, hematoma). Cry strong, lusty, medium pitch (high-pitched cry suggests genetic abnormality, hypoglycemia, or prolonged narcotic  effect). Respiration Apgar Score: 1/5 optimal score 7–10 Rate ranges from 30–60/min; periodic pattern may be noted Breath sounds bilateral; occasional crackles common initially Thorax cylindrical; prominent xiphoid cartilage common Safety Temperature ranges from 97.7°F–99.4°F (36.5°C–37.5°C). Some vernix present (amount and distribution dependent on gestational age). Skin: Smooth, flexible; peeling of hands/feet may be noted; pink-tinged or ruddy color; may be mottled, display minor  bruising (e.g., forceps delivery), or harlequin color changes; petechiae on head/face (may reflect increased  pressure associated with delivery or nuchal cord); port-wine stains, telangiectatic nevi (eyelids, between brows, or  on occiput), or mongolian spots (primarily lower back and buttocks) may be noted. Scalp abrasion may be present (internal electrode placement). DIAGNOSTIC STUDIES Cord pH:  Levels of 7.20–7.24 reflect a preacidotic state; lower levels indicate significant asphyxia. Hb/Hct:  Hb level of 15–20 g and Hct of 43%–61%. Direct Coombs’ Test on Cord Blood:  Determines presence of antigen-antibody complexes on red blood cell (RBC)
