1. Physical assessment of the newborn can be divided into 3 phases: initial assessment using Apgar score, transitional assessment of periods of reactivity, and a period of stabilization.
2. Key assessments include vital signs like temperature, pulse, respiration; physical exams of general appearance, head/neck, chest, heart, abdomen, back, limbs; and neurological assessment of primitive reflexes.
3. Primitive reflexes present at birth like sucking, rooting, and moro reflexes are important for survival and typically disappear by 3-4 months as the baby develops higher brain functions.
