Study Notes
Factors Defining High-Risk Infants
- Demographic Social Factors: Maternal age of 40 years, usage of illicit drugs, alcohol, and cigarettes, poverty, unmarried status, and exposure to emotional or physical stress increase infant risk.
- Past Medical History: Conditions such as genetic disorders, diabetes, hypertension, asymptomatic bacteriuria, rheumatologic illnesses, immune-mediated diseases, and long-term medication use heighten the risk for infants.
Timing of Primitive Reflexes
- Palmar Grasp: Onset at 28 weeks gestation, fully developed by 32 weeks, lasts 2-3 months postnatal.
- Rooting Reflex: Begins at 32 weeks gestation, fully developed by 36 weeks, becomes less prominent after 1 month postnatal.
- Moro Reflex: Onset between 28-32 weeks gestation, fully developed by 37 weeks, persists for 5-6 months postnatal.
- Tonic Neck Reflex: Onset at 35 weeks gestation, fully developed by 1 month postnatal, lasts 3-4 months postnatal.
- Parachute Reflex: Begins at 7-8 months postnatal, fully developed by 10-11 months, remains throughout life.
Periods of Growth
-
Prenatal Period:
- Zygote: 0 to 14 days of gestation; fertilized egg’s journey to and implantation in the uterus.
- Embryo: 3 weeks to 8 weeks of gestation; organogenesis occurs, laying the foundation for major body structures.
- Fetus: 9 weeks to birth; characterized by rapid growth and organ maturation.
- Perinatal Period: 22 weeks of gestation to 7 days after birth; focuses on the transition from intrauterine to extrauterine life.
-
Postnatal Period:
- Newborn (Neonate): First 4 weeks post-birth; neonates learn essential survival skills.
- Infancy: First year marked by rapid growth and early cognitive development.
- Toddler: Ages 1 to 3 years; development of motor skills and language, often marked by behavioral outbursts.
- Preschool Child: Ages 3 to 6 years; refinement of skills, imaginative play, and early social interactions.
- School-Age Child: Ages 6 to 12 years; steady cognitive and physical development, critical thinking, and social relationship building.
-
Adolescence:
- Early Adolescence: Ages 10 to 13 years; onset of puberty and emotional changes.
- Middle Adolescence: Ages 14 to 16 years; further physical maturation and identity exploration.
- Late Adolescence: Ages 17 to 19 years; final stages of growth and transition into adulthood and defined social roles.
