Study Notes
Infant (Birth - 1 Year)
- Infants transition from complete dependency to self-sufficiency.
- Average birth weight is 6-7 pounds, with variations.
- Weight doubles by 6 months and triples by 12 months.
- Head accounts for 25% of body weight.
- Narrow airways can lead to obstruction.
- Key breathing muscles are the nose and diaphragm.
- Infants initially rely on maternal antibodies, building their own immunity over time.
- Reflexes present at birth diminish:
- Moro reflex (startle): Arms out, fingers spread, grasp.
- Palmer reflex: Grasping when palm is touched.
- Rooting reflex (hunger): Turning towards cheek stimulation.
- Sucking reflex: Initiated by lip stimulation.
- Sleep patterns:
- Initially 16-18 hours.
- Gradually transitions to 4-6 hours during the day and 9-10 hours at night.
- Growth plates at the ends of bones contribute to limb growth; musculoskeletal injuries are concerning.
- Fontanels (gaps in skull):
- Posterior fontanelle: Closes around 2-3 months.
- Anterior fontanelle: Closes between 9-18 months.
- Sunken fontanels: Indicate dehydration.
- Bulging fontanels: Indicate increased intracranial pressure or crying.
- Infants develop trust and thrive in predictable environments.
- Learn through scaffolding, building on existing knowledge.
Toddler (12-36 Months)
- Body temperature: 98.6-99.6 degrees Fahrenheit.
- Weight gain: Approximately 4 pounds per year.
- Body systems become more efficient:
- Pulmonary: Terminal airways and alveolar spaces grow.
- Nervous: Brain reaches 90% of adult weight.
- Muscle development: Improved muscle mass and bone density.
- Immune: Still developing, making toddlers susceptible to illness.
- Toilet training:
- Physically possible 12-15 months.
- Psychologically possible 18-30 months.
- Language development, understanding cause and effect.
- Separation anxiety may occur.
- Magical thinking and imaginative play emerge.
Preschool Age (3-5 Years)
- Continued growth and development of body systems.
- Increased social interaction and skill development.
- Peer groups provide information and diverse perspectives.
- Peer interactions offer learning, comparison, and belonging.
School Age (6-12 Years)
- Body temperature: 98.6-100.3 degrees Fahrenheit.
- Weight gain: Approximately 6 pounds per year.
- Height increase: 2-2.5 inches per year.
- Primary teeth lost, replaced by permanent teeth.
- Increased time away from parents, developing decision-making skills.
- Self-esteem influenced by peers and emotional support (or neglect).
- Moral code develops (rewards/punishments, then internal motives).
Adolescence (13-18 Years)
- Second major growth spurt (2-3 years).
- Growth affects feet, hands, arms, and legs.
- Sexual maturity and secondary sexual characteristics develop.
- Seeking independence and personal identity.
- Interest in sex emerges.
- Body image concerns lead to potential self-destructive behaviors.
- Personal code of ethics with specific expectations develops.
Early Adulthood (19-40 Years)
- Lifelong habits are established from adolescence.
- Peak physical condition generally between 19-26.
- Career and family development occur.
- Increased stress levels.
- Accidents are a leading cause in death, along with risk-taking behaviours.
Middle Adulthood (41-60 Years)
- No significant changes in vital signs (but vision correction may be needed).
- Chronic diseases (high cholesterol, heart disease, and cancer) become more common.
- Menopause begins in women.
- Task-oriented, focus on problem solving.
- "Empty nest" stage as children leave home.
- Balancing care for elderly parents and adult children.
Late Adulthood (61+ Years)
- Physical downslope.
- Vital signs may fluctuate.
- Decline in body systems (cardiovascular, respiratory, and endocrine).
- Sleep quality decreases.
- Environmental changes, self-worth, and financial burdens are challenges.
- Dealing with death and dying is prevalent.
- Motivations and interests change based on mobility, social interaction, and finances.
Vital Signs and Lifespan Development
- Vital signs change throughout lifespan, reflecting body maturation.
- Heart rate and respiratory rate typically decrease with age.
- Blood pressure tends to increase as the body becomes more efficient.
Understanding Lifespan Development in Healthcare
- Understanding lifespan development helps healthcare providers:
- Set realistic expectations based on the patient's life stage.
- Recognize varying abilities in maturity and communication.
- Connect effectively with patients and understand their experiences.
